"User interface is the space where interactions between humans and machines occur. The goal of this interaction is to allow effective operation and control of the machine from the human end, whilst the machine simultaneously feeds back information that aids the operators decision making process. [...] Generally, the goal of human-machine interaction engineering is to produce a user interface which makes it easy (self explanatory), efficient, and enjoyable (user friendly) to operate a machine in the way which produces the desired result. This generally means that the operator needs to provide minimal input to achieve the desired output, and also that the machine minimizes undesired outputs to the human." [Wikipedia]

Report: NSA implants software to spy on 100,000 foreign computers
The National Security Agency has implanted software in nearly 100,000 computers around the world — but not in the United States — that allows the U.S. to conduct surveillance on those machines,The New York Times reported Tuesday.
The Times cited NSA documents, computer experts and U.S. officials in its report about the use of secret technology using radio waves to gain access to computers that other countries have tried to protect from spying or cyberattacks. The software network could also create a digital highway for launching cyberattacks, the Times reported.
The Times reported that the technology, used by the agency for several years, relies on radio waves that can be transmitted from tiny circuit boards and USB cards inserted covertly into the computers. The NSA calls the effort an “active defense” and has used the technology to monitor units of China’s army, the Russian military, drug cartels, trade institutions inside the European Union, and sometime U.S. partners against terrorism like Saudi Arabia, India and Pakistan, the Times reported.

- Thermal Plastic is a composite material based on engineering plastics with non-metallic thermal conductive materials added.
- After it is made into plastic heat sinks or plastic shells, it can have higher heat dissipation performance than ceramic or general engineering plastic heat sinks. Moreover, Thermal Plastic has higher temperature resistance than ordinary plastics.
Thermal Conductivity：2／4.5／6 W/m•K
Material：PC / PA
Thermal Deformation Temperature：180~210℃
Application：Case / Heat Sink / Display Card Backplane
For electronic products that require no metal heat sinks or metal casings, or other product characteristics that need to be considered to prevent radio frequency interference, in the past decade, more and more thermal engineers will give priority to using Thermal Plastic heat dissipation solutions in their designs.
For example: Arcadyan Technology / Alpha Networks has applied Thermal Plastic in the heat dissipation solutions designed by customers, and the heat dissipation application in the smart electric vehicle industry supply chain will gradually become popular in the future.

UBEAM. THE PHYSICS IS SOUND™FIRST, LET’S GET SOME FACTS STRAIGHT…
WHAT IS SOUND?
Sound is vibration of the air (or other media). Sound waves enter the ear canal and vibrate the eardrum, causing signals to travel from the inner ear and then to the brain. The brain translates this “noise” into information. The rate at which sound vibrates molecules back and forth is described as cycles per second, or hertz (Hz). Humans hear sounds that move back and forth through a space 20 to 20,000 times per second – this is described as 20,000 Hz (or 20 kHz).
WHAT IS ULTRASOUND?
The range of human hearing is between 20 Hz and 20 kHz; sound below 20 Hz (called infrasound) and sound above 20 kHz (called ultrasound) cannot be detected by human ears. Thus, ultrasound waves are sound waves with frequencies higher than the upper limit of human hearing. uBeam is an ultrasound wireless power delivery system designed to safely charge mobile devices. Our team is comprised of the world’s leading experts in ultrasound and electronics, with decades of experience in all aspects of the system. The technology, the product’s safety, and how the system impacts the surrounding world have been extensively studied. Like all technology companies in the product development process, with critical intellectual property, at this time, we cannot release our full technical specifications to the public. However, we’ll give you a little taste of how our system works and why it’s safe, and as we approach product release we will provide more system specifications to your heart’s delight.
HOW IT WORKS
The uBeam system is composed of two parts: a transmitter that emits energy, and a receiver that receives energy. The transmitter is like a sound speaker, but instead of emitting audible sound, uBeam’s transmitter emits high frequency sound. This sound can’t be heard by humans or dogs; it’s called ultrasound. The receiver, like a microphone, picks up the sound and converts it into usable energy.
Sound, like light and wind, is a form of energy that can be converted into electrical energy with our proprietary energy harvesting technology. The receiver then sends this electrical power to charge or power an electronic device. Today, ultrasound technology is not designed for power transmission. Ultrasonic transducers are designed for medical imaging, distance measurement, and industrial cleaning. In order to make wireless power transmission via ultrasound commercially viable, uBeam engineered several incredibly difficult (but not impossible) things: • We invented a novel high-powered ultrasonic transducer. • We developed the thinnest, most powerful, most complex, and most intelligent ultrasonic transmitter in the world. • We developed a highly secure ultrasonic data transmission system. • We developed a receiver that could efficiently convert airborne ultrasound into usable power. uBeam’s multiple inventions have enabled the world’s most powerful, safe, and intelligent true over-distance commercial wireless power system for consumer electronics.
THE SAFETY OF SOUND
Ultrasound has been used safely for 100 years. It has been used in medicine since the 1940s. Its use in obstetrics began to increase in the 1960s. Ultrasound is considered safe for humans and wildlife and is employed routinely in the examination of developing fetuses. Fetuses are the most vulnerable organisms to injury, and the safety of ultrasound is in stark contrast to the absolute danger of ionizing radiation such as x-rays in examining developing fetuses. The safety of ultrasound has been examined for over 30 years and various occupational medicine scientific studies have failed to identify dangers of either industrial or medical ultrasound. The most recent paper to investigate the safety of ultrasound was just published in the January 2016 issue of Ultrasonics. In this paper, ultrasound energy was delivered to pig tissue to charge a device under the skin. The pigs were subjected to repeated charging of high intensity over 5 weeks and then the tissue that was subjected to the ultrasound was looked at under the microscope. There was no injury to the tissue, indicating that the ultrasound energy was safe. Of note is that this study used energy levels to tissue that were orders of magnitude higher than levels that uBeam’s system uses. uBeam is designed to charge devices outside of the human body and this type of ultrasound would not be expected to penetrate skin. This particular study supports that, even if the uBeam could penetrate skin, there would be no injury. Ultrasound in the very high frequencies (Megahertz, or MHz, 1000x higher frequency than kHz) is widely used in the medical field, and is the most common medical imaging modality used in almost all specialties due to its versatility and safety. In fact, nearly everyone under the age of 50 in the United States was imaged in-utero by ultrasound, and it is considered a routine and standard procedure.

Semiconductor Liquid Cooling
Semiconductors are key components used in the manufacture of transistors, diodes and integrated circuits. As demand for high-power computing has increased, so has demand for densely packaged semiconductor devices. While in use, semiconductors generate a high level of thermal energy, and smaller packages make that energy more difficult to regulate.
When a semiconductor device or chip overheats, its functionality can slow down or fail completely, leading to data loss and system crashes. Traditionally, engineers have used air cooling systems to keep the temperature of electronic components under control. However, air cooling can no longer keep up with the heat generated by increasingly powerful and compact systems. Semiconductor liquid cooling systems offer an effective alternative for temperature control. Microchannel cold plates for semiconductors circulate coolant fluids with high thermal conductivity evenly over the entire heated surface of the chip.
At Mikros Technologies, we design and manufacture microchannel cold plates for semiconductor cooling applications.
Semiconductor Temperature Control
Semiconductor chips can be either lidded or unlidded. In a lidded chip, a thermal
interface material sits between the die and a copper lid mounted to the back of
the die. In an unlidded chip, no lid or thermal interface material is present between
the die and the heat sink. Unlidded packages tend to produce lower junction
temperatures, with junction temperature being the maximum operating temperature
of a semiconductor, but both chip styles have their advantages.
We offer semiconductor cooling technologies that can accommodate the thermal management of
both lidded and unlidded chips.
Multi-Chip Packaging (MCP)
Multi-chip modules integrate multiple chips into a single package. With more chips
in a concentrated area, you have more heat to dissipate. Our microchannel cold plates
can dissipate over 1kW/cm2 while keeping surface temperature and pressure drop to a minimum.
To continue boosting computer performance despite the slowing pace of Moore’s Law,
semiconductor device manufacturers have begun making processors using chiplets,
small dies that come together to form larger chips. Our liquid cooling systems cool chiplets
effectively by tailoring the highest cooling zones to the hottest dies.
Semiconductor Thermal Challenges
As semiconductor devices become smaller and more densely packed, new thermal challenges arise, including larger power spikes in hot spots below the surface layer. These issues demand intelligent cooling solutions.
Heat Flux Regulation
Mikros cold plates use tailored cooling to direct more coolant to areas in need of greater heat dissipation. The low thermal resistance of microchannels provides very high heat transfer coefficients for better heat flux regulation.
Semiconductor Module Testing
At Mikros Technologies, we design and produce microchannel cold plates and semiconductor cooling systems with fast thermal transients for unparalleled temperature regulation during rigorous semiconductor testing profiles.
Also known as IC validation, functional testing determines whether an individual semiconductor chip works as intended in a test socket.
A system-level test evaluates how well a chip functions within a complete system by emulating the final user environment on a board.
Burn-in involves placing the semiconductor into extreme operating conditions, including high temperatures, and testing how well it performs.
This process helps detect early failures.
Thermal Head Retrofitting
Mikros can design and produce test heads for existing semiconductor test equipment to save companies on capital costs as higher power chips are released.
The thermal capacity of Mikros semiconductor cooling plates is very low, which allows for millisecond-level thermal response times as test profiles are applied.
High Power Chip Testing
The low thermal resistance of Mikros cold plates allow for higher power tests to be run on higher power chips, speeding the time to market for new semiconductor products.
Benefits of Microchannel Cold Plates for Semiconductor Liquid Cooling
To accommodate the needs of our clients in the semiconductor industry, we often configure our microchannel cold plates
into a variety of complex topologies. Our cold plates increase system reliability by lowering junction temperature
and offer exceptionally low pressure drop, surface temperature rise, low thermal gradients and fast transients.
To learn more about the benefits of our semiconductor module liquid cooling reach out to us today.
In 2022, Mikros was selected by CIO review as one of the 20 most promising semiconductor industry solutions providers.

Implementation of semantic Communications for the general communications system is a Key challenge in the journey towards 6G. While promising significant improvements in channel bandwidth efficiency to go beyond what is generally considered as Shannon theory based communications, semantic communications create new opportunities to modern high bandwidth applications. The need for a highly efficient communication model has become of paramount importance due to the exponential growth in data traffic on image transfers, streaming, video conferencing, and online learning, which consumes a significant amount of system resources and necessitates longer transmission and processing times. This workshop focuses on introducing the theory of semantic communication in relation to multimedia content in a mobile communications system.
In conventional transmission systems, data transmission happens in bit level, where the source is converted into a bit sequence to be transmitted. This data would be text, audio, images, or video. At the receiver end, the bit sequence which represents the original source is recovered to represent the original data. There are many compression techniques developed to transmit data over limited bandwidth channels, but all existing compression and transmission techniques function within the Shannon capacity limit.
In contrast to the conventional transmission model, Semantic Communication models convey only the necessary information required for a specified task. Semantic communications convey the semantic meanings of the original source over the physical communication channel and the receiver intelligently decodes the semantic meaning of the transmitted labels to recover the source data. For instance, in image transmission, semantic communication employs semantic feature extraction of the original images which are of importance to a specified task.
Furthermore, proliferation of video-based machine-to-machine, machine-to-human, and human-to-machine communications (such as automated driving, factory automation, gaming, IoT, and remote sensing) further stresses the already bandwidth limited channel and new ways of designing of the communication systems to be employed. This workshop explains how semantic communication can help in resolving these emerging problems in high volume media transmissions in limited bandwidth applications.
Scope and Information for Participants:
The objective of this workshop is to introduce semantic communication theory and its importance in current high volume low bandwidth applications specially in mobile communications. During the session, potential practical applications of semantic communication, its current limitations, and future direction will be discussed. In contrast to the conventional communication applications and data compression techniques, an increasing share of data content is analyzed by machines rather than humans, and hence the importance to optimize the transmission and compression techniques to suit the machines are discussed.
We expect to present our study on semantic communication-based image transmission system architecture based on Generative Adversarial Network (GAN) which emphasizes the impact of the physical channel characteristics, specifically the channel noise and quantization noise, in semantic communication systems used for image transmission.
Further, we will present a theoretical architecture that will utilize semantic communication for the transmission of video content over a wireless communication channel.

What is CTV?
Connected TV (CTV) is the future of television. It is a cordless delivery of televised content, streaming over any device connected to the internet. Advertisement-powered CTV entails video on demand transacted programmatically, alleviating subscription fatigue and reducing the overall cost of content for the end user.
How CTV ads work?
Connected TV is a smart TV, smartphone, desktop, tablet, or any device that is connected to the internet and facilitates the delivery of streaming content.
A CTV device connects to the internet through built-in capabilities or an external over-the-top (OTT) piece of equipment that enables a standard TV to become “smart.”
CTV advertising occurs during the in-app experience. In addition to typical programmatic targeting capabilities, CTV ads can be based on the operating system, app, or content producer the user is engaged with.
A video ad similar to pre- and mid-roll ads on computers, laptops, and smartphones appears. The overall user experience remains similar to traditional TV.


BUSINESSES across central Victoria will benefit from an increased access to new and emerging technologies once the National Broadband Network is rolled out.
Bendigo Community Telco put on a NBN connectivity update breakfast on Thursday morning with a number key businesses leaders in attendance.
NBN general manager of product marketing and service provider Timothy Smith was a guest speaker at the event.
Mr Smith spoke about the benefits the NBN could have for businesses in Bendigo and the progress of the roll out across the city.
Bendigo Community Telco business development general manager Adam Murdoch said there were a number of technologies through the NBN that could help businesses.
He said the NBN would improve productivity, give better access to new markets and cut costs on business phone, internet and inter-office communication.
He said it would allow local businesses to compete on a global scale.
"Some of these services that are available they really only possible or work properly over high (connection) and that is what NBN is bringing us," he said.
"There is a lot less risk (for businesses) too.
"They don't have to have all the equipment on site and can just be provided with it through their date service.
"It reduces risk, adds productivity - there are lots of benefits."
Mr Murdoch said the NBN was available to 7000 households in Greater Bendigo, including Longlea, Lockwood South and Eppalock.
He said it would still be about 12 to 18 months before the NBN would be rolled out in central Bendigo.
Mr Murdoch said BTC was a direct NBN retail service provider and households that want the service could get it through the business.
"Was they start deploying in Bendigo they will roll that right through," he said.
"It's more economical to have their teams work in an area and finish then move on."
To find out where the NBN is available visit www.bendigotelco.com.au or call Bendigo Community Telco on 1300 228 123.


Rocket Science Scale: 5
Let’s Set the Mood:
This article isn’t about the impending doom of how we are going to destroy the earth. It is about space satellites and how we plan on putting thousands upon thousands more up there.
This article was thought of after hearing that Elon Musk wanting to make a “Space Internet”. He’s opening up a Seattle branch of SpaceX to continue work on the the SpaceX rockets and possibly start a Space Internet.
It is an interesting concept. The plan is to launch a hundreds (the number changes depending on the source). It should allow faster internet speeds to everyone in the world including third world countries. The plan to allow those speeds is to launch the hundreds of satellites into very low earth orbit (about 750 miles above Earth) so they can communicate to each other faster. Or at least that’s Elon Musk’s plan.
To him the satellites would be the base for future communications to a Mar’s colony. Keep your eyes on the prize Elon.
What was interesting to me is the recent attention on a Space Internet was because Musk announced it as his new pet project. But the Space Internet seems to actually be the idea of Greg Wyler.
Wyler has created three total startups that have to do with setting communication networks. The first was Terracom, which was a successfully 3G network in Rwanda to set up cell and internet service (with the use of a fiber optic cable). This increased communication within Rwanda but was slow for international communications. Next he set up a company called O3b which has 12 satellites around 5000 miles from Earth which provides internet in the Pacific.
And now he has moved on to OneWeb. It is supposedly cheaper than Elon Musk’s plan (2 billion to 10), and would feature satellites about 750 miles away from the Earth’s surface (sound familiar). OneWeb has also secured funding from large investors like Virgin Group and Qualcomm.
Apparently Wyler and Musk are friends. The key thing from both their plans is it would provide a cheap internet to everyone in the world. Cool concept right? I think Wyler has a better start since he has already set up a satellite network and experience does help when finding investors. I’m pretty sure Musk’s plan is funded internally.
My only concern with both plans is maintenance of the satellites. If they die after three – five years , both companies should have a plan to remove them from space and replace them with a new one. Otherwise, the Earth will be covered with space junk.
So my opinion: Yay Space Internet but boo space junk. It’ll be interesting to see what happens!

Windows Sockets – A commonly used application programming interface (API) that Windows applications use to transfer data using TCP/IP.
A NetBIOS name is a 16-byte name that identifies a NetBIOS application on the network. A NetBIOS name is either a unique (exclusive) or group (nonexclusive) name. When a NetBIOS application communicates with a specific NetBIOS application on a specific computer, a unique name is used. When a NetBIOS process communicates with multiple NetBIOS applications on multiple computers, a group name is used.
The NetBIOS name identifies applications at the Session layer of the OSI model. For example, the NetBIOS Session service operates over TCP port 139. Because all NetBT session requests are addressed to TCP destination port 139, a NetBIOS application must use the destination NetBIOS name when it establishes a NetBIOS session.
An example of a process using a NetBIOS name is the file and print sharing server service on a Windows–based computer. When your computer starts up, the server service registers a unique NetBIOS name based on your computer’s name. The exact name used by the server service is the 15-character computer name plus a 16th character of 0x20. If the computer name is not 15 characters long, it is padded with spaces up to 15 characters long. Other network services also use the computer name to build their NetBIOS names, and the 16th character is typically used to identify each service.
When you attempt to make a file-sharing connection to a computer running Windows by specifying the computer’s name, the Server service on the file server that you specify corresponds to a specific NetBIOS name. For example, when you attempt to connect to the computer called CORPSERVER, the NetBIOS name corresponding to the Server service is CORPSERVER <20>. (Note the padding using the space character.) Before a file and print sharing connection can be established, a TCP connection must be created. For a TCP connection to be created, the NetBIOS name CORPSERVER <20> must be resolved to an IPv4 address. NetBIOS name resolution is the process of mapping a NetBIOS name to an IPv4 address.
For more information about NetBT and NetBIOS name resolution methods, see Chapter 11, “NetBIOS over TCP/IP.”
Application Programming Interfaces
Windows networking applications use two main application programming interfaces (APIs) to access TCP/IP services in Windows: Windows Sockets and NetBIOS. Figure 2-6 shows these APIs and the possible data flows when using them.
Figure 2-6 Architecture of the Windows Sockets and NetBIOS APIs
Some architectural differences between the Windows Sockets and NetBIOS APIs are the following:
NetBIOS over TCP/IP (NetBT) is defined for operation over IPv4. Windows Sockets operates over both IPv4 and IPv6.
Windows Sockets applications can operate directly over the IPv4 or IPv6 Internet layers, without the use of TCP or UDP. NetBIOS operates over TCP and UDP only.
Packet Multiplexing and Demultiplexing
When a sending host sends an IPv4 or IPv6 packet, it includes information in the packet so that the data within the packet can be delivered to the correct application on the destination. The inclusion of identifiers so that data can be delivered to one of multiple entities in each layer of a layered architecture is known as multiplexing. Multiplexing information for IP packets consists of identifying the node on the network, the IP upper layer protocol, and for TCP and UDP, the port corresponding to the application to which the data is destined. The destination host uses these identifiers to demultiplex, or deliver the data layer by layer, to the correct destination application. The IP packet also includes information for the destination host to send a response.
IP contains multiplexing information to do the following:
Identify the sending node (the Source IP Address field in the IPv4 header or the Source Address field in the IPv6 header).
Identify the destination node (the Destination IP Address field in the IPv4 header or the Destination Address in the IPv6 header).
Identify the upper layer protocol above the IPv4 or IPv6 Internet layer (the Protocol field in the IPv4 header or the Next Header field of the IPv6 header).
For TCP segments and UDP messages, identify the application from which the message was sent (the Source Port in the TCP or UDP header).
For TCP segments and UDP messages, identify the application to which the message is destined (the Destination Port in the TCP or UDP header).
TCP and UDP ports can use any number between 0 and 65,535. Port numbers for client-side applications are typically dynamically assigned when there is a request for service, and IANA pre-assigns port numbers for well-known server-side applications. The complete list of pre-assigned port numbers is listed on .
All of this information is used to provide multiplexing information so that:
The packet can be forwarded to the correct destination.
The destination can use the packet payload to deliver the data to the correct application.
The receiving application can send a response.
When a packet is sent, this information is used in the following ways:
The routers that forward IPv4 or IPv6 packets use the Destination IP Address field in the IPv4 header or the Destination Address in the IPv6 header to deliver the packet to the correct node on the network.
The destination node uses the Protocol field in the IPv4 header or the Next Header field of the IPv6 header to deliver the packet payload to the correct upper-layer protocol.
For TCP segments and UDP messages, the destination node uses the Destination Port field in the TCP or UDP header to demultiplex the data within the TCP segment or UDP message to the correct application.
TCP Three-Way Handshake
A TCP connection is initialized through a three-way handshake. The purpose of the three-way handshake is to synchronize the sequence number and acknowledgment numbers of both sides of the connection and to exchange TCP window sizes. The following steps outline the process for the common situation when a client computer contacts a server computer:
1. The client sends a TCP segment to the server with an initial sequence number for the connection and a window size indicating the size of a buffer on the client to store incoming segments from the server.
2. The server sends back a TCP segment containing its chosen initial sequence number, an acknowledgment of the client’s sequence number, and a window size indicating the size of a buffer on the server to store incoming segments from the client.
3. The client sends a TCP segment to the server containing an acknowledgment of the server’s sequence number.
TCP uses a similar handshake process to end a connection. This guarantees that both hosts have finished transmitting and that all data was received.
To use TCP, an application must supply the IP address and TCP port number of the source and destination applications. A port provides a location for sending segments. A unique number identifies each port. TCP ports are distinct and separate from UDP ports even though some of them use the same number. Port numbers below 1024 are well-known ports that the Internet Assigned Numbers Authority (IANA) assigns. Table 2-9 lists a few well-known TCP ports.
TCP Port Number
FTP (data channel)
FTP (control channel)
HTTP used for the World Wide Web
NetBIOS session service
Transmission Control Protocol (TCP)
TCP is a reliable, connection-oriented delivery service. Connection-oriented means that a connection must be established before hosts can exchange data. Reliability is achieved by assigning a sequence number to each segment transmitted. TCP peers, the two nodes using TCP to communicate, acknowledge when they receive data. A TCP segment is the protocol data unit (PDU) consisting of the TCP header and the TCP payload, also known as a segment. For each TCP segment sent containing data, the receiving host must return an acknowledgment (ACK). If an ACK is not received within a calculated time, the TCP segment is retransmitted. RFC 793 defines TCP.
Table 2-8 lists and describes the key fields in the TCP header.
TCP port of sending application.
TCP port of destination application.
Sequence number of the first byte of data in the TCP segment.
Sequence number of the next byte the sender expects to receive from its TCP peer.
Current size of a memory buffer on the host sending this TCP segment to store incoming segments.
A simple mathematical calculation that is used to check for bit-level errors in the TCP segment.
Multicast Listener Discovery (MLD)
MLD is the IPv6 equivalent of IGMP version 2 for IPv4. MLD is a set of ICMPv6 messages exchanged by routers and nodes, enabling routers to discover the set of IPv6 multicast addresses for which there are listening nodes for each attached interface. Like IGMPv2, MLD discovers only those multicast addresses that include at least one listener, not the list of individual multicast listeners for each multicast address. RFC 2710 defines MLD.
Unlike IGMPv2, MLD uses ICMPv6 messages instead of defining its own message structure. The three types of MLD messages are:
Multicast Listener Query Routers use Multicast Listener Query messages to query a subnet for multicast listeners.
Multicast Listener Report Multicast listeners use Multicast Listener Report messages to either report interest in receiving multicast traffic for a specific multicast address or to respond to a Multicast Listener Query message.
Multicast Listener Done Multicast listeners use Multicast Listener Done messages to report that they might be the last multicast group member on the subnet.
Windows Server 2008 and Windows Vista also support MLD version 2 (MLDv2), specified in RFC 3810, which allows IPv6 hosts to register interest in source-specific multicast traffic with their local multicast routers. A host running Windows Server 2008 or Windows Vista can register interest in receiving IPv6 multicast traffic from only specific source addresses (an include list) or from any source except specific source addresses (an exclude list).
A highly useful aspect of IPv6 is its ability to automatically configure itself without the use of an address configuration protocol, such as Dynamic Host Configuration Protocol for IPv6 (DHCPv6). By default, an IPv6 host can configure an address for use on the subnet for each interface. By using router discovery, a host can also determine the addresses of routers, additional addresses, and other configuration parameters. Router Advertisement messages indicate whether an address configuration protocol should be used. RFC 4862 defines IPv6 address autoconfiguration.
For more information about IPv6 address autoconfiguration, see Chapter 6 “Dynamic Host Configuration Protocol.”
Router discovery is the process through which hosts attempt to discover the set of routers on the local subnet. In addition to configuring a default router, IPv6 router discovery also configures the following:
The default setting for the Hop Limit field in the IPv6 header.
A determination of whether the node should use an address configuration protocol, such as Dynamic Host Configuration Protocol for IPv6 (DHCPv6), for addresses and other configuration parameters.
The list of subnet prefixes defined for the link. Each subnet prefix contains both the IPv6 subnet prefix and its valid and preferred lifetimes. If indicated, the host uses the subnet prefix to create an IPv6 address configuration without using an address configuration protocol. A subnet prefix also defines the range of addresses for nodes on the local link.
The IPv6 router discovery processes are the following:
IPv6 routers periodically send multicast Router Advertisement messages on the subnet advertising their existence as routers and other configuration parameters such as address prefixes and the default hop limit.
IPv6 hosts on the local subnet receive the Router Advertisement messages and use their contents to configure addresses, a default router, and other configuration parameters.
A host that is starting up sends a multicast Router Solicitation message. Upon receipt of a Router Solicitation message, all routers on the local subnet send a unicast Router Advertisement message to the host that sent the router solicitation. The host receives the Router Advertisement messages and uses their contents to configure addresses, a default router, and other configuration parameters.


PaliApps uses secure third party key management from Scentrics to securely encrypt messages and data. Using SEnDs as an example, these are sent over traditional communication channels such as SMS and Email with one-click encryption and control who sees data, wherever it is.
SEndS secures your messages without changing the way you communicate. This means:
Messages are sent using a cryptographic system that encrypts and authenticates the messages. The process is illustrated below and shows how the sender’s phone uses a secret key to encrypt the message making it indecipherable. The receiving phone can then decrypt the message. The uniqueness of the service is where the keys are stored and how they are made available to the intended message recipient.
The role of the authentication tag is to guarantee to the recipient that the received e-mail or text message is identical to the original transmission. Only somebody who has the secret key can create a valid tag. This means that when your phone verifies the tag, you know that the sender had the secret key and that you are indeed communicating with the right person.
For encryption and authentication, we use the AES-EAX standard and for optimum security we use the maximal possible key size, which is 256-bit keys. For the secure channel between the user and Scentrics key server we use TLS with 2048-bit RSA keys and certificate pinning that ensures SEndS will only instantiate TLS connections with Scentrics.
In our apps, we use a novel patented Server-centric key management system that eliminates the hassle of key management. Instead of you storing the keys on your phone, the keys are stored securely in cloud and provide the keys to your phone exactly when needed. One advantage of this solution is that your data is still secure even if your phone is stolen, as the keys are not stored with the data. Moreover, if you have several phones you do not need to copy keys between them; all keys are automatically available on any phone where you have installed PaliApps products.
Our apps use SaaS based key management for scalability, security and ease of management. One huge advantage is that keys are separated from the encrypted data.
Protect your data against theft by hackers or data breaches by encrypting it
Stop internet companies reading your messages - without encryption keys, they cannot access or scan your messages
Take control of your online privacy, controlled through your personal Privacy Account
Log in once to secure your data from multiple linked accounts including emails, phone numbers and more
Encryption keys are stored in the cloud and not on your device, so if your device is lost your protected data stays secure.
Choose to make any message private, on any device – giving you confidence to send personal data and images to anyone from anywhere.
One click secures your messages from anyone capturing your data, including hackers, email companies and marketeers
With SEndS, your encryption keys are linked to your Privacy Account. The Privacy Account is a new and secure service that aims to give all users easy, single sign-in access to encryption and to control their data.
Think of your online self as a digital estate - from youth, you contribute to this estate with data – selfies, emails, financial data. Given enough time, it's everything you are. The Privacy Account becomes a protected estate so that only YOU can access it - after all, it’s your legacy.
From the Privacy Account itself, you can keep your data under lock and key. Keys are generated for the user and the user alone – keys separated from the content it's associated with.
Login with your Privacy Account wherever you see the “Secure with Scentrics” padlock symbol.

34 Percent of China’s 5G Contract Goes to Ericsson. 10 Percent Goes to Nokia
China practicing what it preaches, westerners welcome to help build its telecom infrastructure
China’s largest telecommunications operator China Mobile has awarded half of its 5G network equipment contracts to Huawei Technologies, in a boon for the Chinese telecoms giant after being squeezed in overseas markets by a US decision to add it to a trade blacklist.
Huawei will provide 49 per cent of the MME/SGSN equipment and 54 per cent of the SAE-GW/GGSN equipment – two types of core network equipment needed for the operation of ultra-fast 5G networks – to China Mobile, according to the results of a tender posted on the telecom operator’s website.
Sweden’s Ericsson and Finland’s Nokia bagged 34 per cent and 12 per cent of the MME/SGSN equipment orders, as well as 34 per cent and 9 per cent of the SAE-GW/GGSN orders respectively. ZTE Corp, Huawei’s crosstown rival in Shenzhen, was awarded 5 per cent of the MME and 3 per cent of the SAE 5G equipment orders.
“We have set up a fair and transparent procurement policy and potential vendors have to go through a vigorous tender process,” said China Mobile in an emailed response to a request for comment. “We have considered factors such as price, product quality and customer service in arriving at the final decision. Huawei is one of our major long-term suppliers and over the years it has consistently provided us with exceptional products and services.”
The company added it would continue to work with both domestic and international suppliers.
On June 6, China granted commercial 5G licences to the country’s three telecommunications network operators and the nation’s cable network giant, signalling major new investments in the world’s largest mobile market amid a raging tech war with the United States.
The award of the 5G licences came after the US government put Huawei on a trade blacklist last month, which has severed the Shenzhen-based company’s access to American hi-tech suppliers, including semiconductor firms Qualcomm and Intel as well as software providers Google and Microsoft.
“Huawei is fully prepared” for the roll-out of commercial 5G networks in China, the company said in a statement after China granted the 5G licences.
Huawei declined to comment on China Mobile’s announcement today.
Hong Kong-listed China Mobile, Unicom and China Telecom currently buy their network equipment from multiple suppliers, including Nokia and Ericsson. The technological advances made by Huawei and ZTE, however, have enabled them to expand their share of the market among China’s leading carriers over the past two generations of mobile systems.
Huawei announced earlier this month that it has obtained 46 commercial 5G contracts from 30 countries. Ericsson and Nokia have publicly announced they have secured 21 and 43 5G commercial contracts respectively. ZTE has not disclosed its recent 5G contract figures.

Securing Municipality's Industrial Control System (ICS) Through Data Flow Analytics
Traditionally, Industrial Control Systems (ICS) were isolated, independent systems that were not integrated into modern IT networks or infrastructure. Interconnecting these devices with IT networks is posing new, unrealized threats that these systems were not designed to mitigate. Furthermore, the industries that leverage ICS technologies have failed to fully investigate or properly mitigate these threats. This case study presents the use of a toolset CLIQUE within a metropolitan critical infrastructure ICS network.

Sometimes, I think KISS is the best solution.
We finally purchased an ICOM 802M SSB radio and AT-140 antenna tuner for better or worse. If you are not familiar with the radio, the radio has a remote head and speaker, hence the transceiver can be mounted in “almost” any location. Now the challenge is to find a location to mount the transceiver and antenna tuner without losing too much storage space. In an effort to “do things right” I telephoned ICOM and discussed mounting locations. The ICOM technician was helpful and polite but strongly recommended I employ a marine professional who was very experienced at installing SSB radios and antenna tuners.
ICOM recommended a location that has at least 1 ft of space around each of the sides of the unit, as well as the top. This is to allow sufficient air space for the heat generated by the transceiver to disperse without overheating the unit. Further, the two modules - transceiver, tuner - and cables should not be located too close to other DC wiring or instrument cables. ICOM pointed out the units and their associated cables may cause feedback into other instruments and radios via the DC wiring or other instrument cables. The engine compartment is not recommended because it is hot and RF from the alternator may cause noise in the radio. It was also recommended I read the NMEA standards for installing SSB radios, &C. According to the technician, these were available online. I checked NMEA’s website (http://www.nmea.org/) and for a cost of $270 and $340, I may purchase the standards. Based on my conversation with ICOM, it seems near impossible to install the radio and tuner within the space of a small boat under let’s say 50 ft LOD. Of course, ICOM did admit, sometimes one has to compromise. Unfortunately, the ICOM manual does not include these installation recommendations.
My SSB installation on IDUNA will be as follows. The antenna tuner will be mounted on the starboard side of the transom inside the lazaretto. This will place the tuner about 1 ft from the battery box, approximately 2 ft from the battery cables and at least 3 ft from the fluxgate compass head. I may need to move the fluxgate head, if I detect any interference when transmitting. The remote head and speaker are already mounted on the side of the cabin above the chart table. I will mount the transceiver below the chart table - (note: IDUNA’s interior is different than found on a SLM boat - Canadian BCC). Routing the cables will be a compromise, in terms of DC wiring and other instrument cables , as I suspect it is on most boats.
I am always amazed how electronic components seem so simple in principle to install become so complicated in practice. If I would have known all of the above before I went to the Annapolis boat show, I would have reverted back to KISS-MA principle when we visited ICOM’s booth.
If you have a SSB radio installed in your Bristol Channel Cutter, I am interested how you solved the space limitation and ICOM recommendations when you installed your radio and tuner. In addition, how well does your transceiver work when transmitting and receiving?

Looking back at the fiber optic cable industry over two to four decades, I notice the trend, as in everything, is to make each device smaller and more feature-filled. This is true in connectors, cables, transceivers etc. Perusing my collection of old fiber optic equipment, I am amazed that some of the early systems were even considered viable for field use.
Over the Years
My collection includes a circa 1980 optical cleaver that used three hand micrometer stages to position and cleave an optical fiber. The unit is about the size of a large laptop and three times as thick. Additionally, a 1980’s Deutsch connector, about the size of a typical phone jack, resides in this collection.
These items would be inconceivable in today’s world as they take up too much room and require far too many specialized skills to operate. On average, it would take about 30 minutes to strip and cleave a fiber and about 60 minutes to connectorize and test one.
Over the years, we have steadily improved all the components of optical communication to levels not thought of in 1980. Today we have connectors that can be installed in 1 to 2 minutes and cables that are approximately 800 times denser than in 1980. This typically follows the semi-conductor curve and should be expected.
However, as we continue this shrinking of the technology in handling, we run into some new concerns. Much like our copper cousins in communications, size matters. In handling these connectors and sharing larger fields on the interconnect plane, we now must take into consideration the ergonomic fact that we humans are not shrinking in size. In making the fiber optic communications patch panel a standard piece of telecommunications hardware, we now face the issue that there will be less trained personnel working with these smaller devices.
We need to understand the human factor as we shrink the real estate of our equipment to accommodate the ever-growing demand for information exchange. The information exchange can be
- between people
- between people and machines or
- between machines in the ‘internet of things’ (where we do not even see the machines exchanging information with each other on our behalf)
Therefore, the question comes down to: Can we continue to shrink our equipment and still allow humans to handle, configure or change it?
Considering Rapid Repair Needs
The aerospace and military use of optical fibers systems have specifications about the accessibility of their systems for rapid repair. I believe that it is time we consider a similar tool set, either software or hardware, that can mimic the requirement for our network systems. As several recent weather events have shown us we may need to rapidly repair networks and need to be aware that accessibility and the ability of intuitive repair processes for less familiar or trained personnel needs to be added in the mix of our next level of design. The goal should not be to limit next generation concepts but rather to include the lessons learned from previous experiences. The use of soft Virtual reality systems only works if the systems can work independently of the damaged network. The same is true of proprietary interconnect systems and schemes.
While there are many competing systems and ideas that all have merit. We need to consider a common repair methodology as we continue to improve, add features and shrink our technology.
