AMD, in cooperation with Aricent and Mentor Graphics, recently demonstrated the first ARM-based Network Functions Virtualization (NFV) solution at ARM TechCon. The demonstration employed AMD's Embedded R-Series "Hierofalcon" SoC virtualizing a Mobile Packet Core running subscriber calls. The 64-bit ARM chip is now sampling to customers and will be generally available in the first half of next year (1H 2015). The AMD NFV Reference Solution is aimed at telecoms for use in communications network backbones where AMD believes an ARM solution will offer reduced costs (both initial and operational) and increased network bandwidth.
The NFV demonstration of the Mobile Packet Core entailed virtualizing a Packet Data Network Gateway, Serving Gateway, Mobility Management Entity, and virtualized Wireless Evolved Packet Core (vEPC) applications. AMD further demonstrated live traffic migration between ARM-based Embedded-R and x86-based second generation R-Series APU solutions. NFV is related to, but independent of, software defined networking (SDN). Network Functions Virtualization is essentially the virtualizing of network appliances with specific functions and performing those functions virtually using generic servers. For example, NFV can virtualize firewalls, gateways, load balancers, intrusion detection, DNS, NAT, and caching functions. NFV virtualizes the upper networking layers (layers 4-7) and can allow virtual tunnels through a network that can then be assigned functions (such as those listed above) on a per-VM or per flow basis. NFV eliminates the need for specialized hardware appliances by virtualizing these functions on generic servers which have traditionally been exclusively x86 based. AMD is hoping to push ARM (and it's own ARM-based SoCs) into this market by touting even further capital expenditure and operational costs versus x86 (and, in turn, versus specialized hardware that serves the entire network whereas NFV can be more exactly provisioned).
It is an interesting take on a lucrative networking market which is dealing with 1.4 Zetabytes of global IP traffic per year. I'm interested to see if the telecoms and other enterprise network customers will bite and give AMD a slice of this pie on the low end and low power fronts.
AMD "Hierofalcon" Embedded R Series SoC
Hierofalcon is the code name for AMD's 64-bit SoC with ARM CPU cores intended for the embedded market. The SoC is a 15W to 30W chip featuring up to eight ARM Cortex-A57 CPU cores capable of hitting 2GHz, two 64-bit ECC capable DDR3 or DDR4 memory channels, 10Gb Ethernet, PCI-E 3.0, ARM TrustZone, and a cryptographic security co-processor.The TechCon demonstration was also used to launch the AMD NFV Reference Solution which is compliant with OpenDataPlane platform. The reference platform includes a networking software stack from Aricent and an Embedded Linux OS and software tools (Sourcery CodeBench) from Mentor Graphics. The OpenDataPlane demonstration featured the above mentioned Evolved Packet Core application on the Hierofalcon 64-bit ARM SoC. Additionally, the x86-based R-Series APU, OpenStack, and Data Plane Development Kit all make up the company's NFV reference solution.

Trendnet has launched a new 802.11ac wireless router called the TEW-919DRU. The new dual band router supports speeds up to 1300 Mbps on the 802.11ac network and 600 Mbps on the 2.4GB 802.11n network.
The router is powered by an undisclosed ARM chip clocked at 1GHz and uses six internal 6 dBi antennas along with beamforming technology to increase stability and range. Trendnet includes five RJ-45 Gigabit Ethernet ports (four LAN, one WAN), one USB 3.0 port, and one USB 2.0 port. Users can simultaneously run an 802.11ac Wi-Fi network and an 802.11n Wi-Fi network. Further, users can add an additional guest Wi-Fi network on each 2.4GHz and 5GHz band as well as multiple SSIDs.
Trendnet also touts that the TEW-818DRU comes with a pre-encrypted Wi-Fi network that is setup out of the box with strong encryption; which is a great feature to see. Unfortunately, the benefits of the out-of-the-box Wi-Fi encryption is undermined by the default support of WPS (Wi-Fi Protected Setup) which has been shown to be insecure. Hopefully new firmware will make WPS opt-in rather than opt-out (if it is indeed possible to truly disable on this model) to get the security nod.
The new 'AC1900' TEW-818DRU wireless router will be available this month with an MSRP of $259.99 and 3 year manufacturer warranty.

Over at Linux.com is a look at five network monitoring tools that will really help you determine not only what is utilizing your network but also its overall health. Bandwidthd is a tool for web hosts and LAN admins which tallies up incoming and outgoing bandwidth usage and can present it in a variety of time frames, from usage per day to usage per year. Nethogs tracks usage per process and Darkstat tracks total usage but comes with an embedded HTTP server which makes it fairly self contained. Speedometer is fairly self explanatory and to understand iperf you should read the write up here as it is a powerful tool for investigating the quality of your network.
"In this roundup of Linux network testing utilities we use Bandwidthd, Speedometer, Nethogs, Darkstat, and iperf to track bandwidth usage, speed, find network hogs, and test performance."

Linaro, a non-profit engineering group, announced a new collaborative organization called the Linux Networking Group at the Embedded Linux Conference in San Francisco this week. The new group will work on developing open source software to be used with ARM-based hardware in cloud, mobile, and networking industry sectors. Of course, being open source, the software for ARM SoCs will be used with Linux operating systems. One of the Linux Networking Group’s purposes is to develop a new “enhanced core Linux platform” for networking equipment, for example.
The new Linux Networking Group is currently comprised of the following organizations:
- Nokia Siemens Networks
- Texas Instruments
The new cooperative has announced four main goals for 2013:
- "Virtualization support with considerations for real-time performance, I/O optimization, robustness and heterogeneous operating environments on multi-core SoCs.
- Real-time operations and the Linux kernel optimizations for the control and data plane.
- Packet processing optimizations that maximize performance and minimize latency in data flows through the network.
- Dealing with legacy software and mixed-endian issues prevalent in the networking space."
Reportedly, Linaro will have an initial software release within the first half of this year. Further, the organization will follow up with monthly software updates to improve performance and add new features. More collaboration and the furthering of ARM-compatible open source software is always a good thing. It remains to be seen how useful the Linux Networking Group will be in pushing its ARM software goals, but here’s hoping it works out for the best.
The full press release can be found below.

Corsair sure does like to expand upon their product base. The company was founded in 1994 and produced only memory for quite a few years. The past five years have seen tremendous growth from the company in terms of SSDs, cases, power supplies, and high end cooling solutions. Corsair also dabbled in sound with a line of successful speakers (though these have not been updated in some time). Corsair is again making another move, but this time with an aime to deliver content around the entire house.
The front of the Roomplayer II is rather bland, but it should hide itself well in nearly any decor.
Simple Audio is a Scottish based company (if it isn't Scottish it's crap!) that designs and sells multimedia streaming solutions. The hardware is the Roomplayer 1 and Roomplayer II units which are high definition media players that are either amplified (forconnecting directly to speakers) or non-amplified to connect to current stereo and home theater systems. Audio is broadcast to these units from iOS enabled devices or PC and Mac computers via software provided by Simple Audio.
Corsair has acquired Simple Audio in a multi-million dollar transaction, but we do not have exact numbers due to Corsair being a privately owned company. From my understanding these products will still carry the Simple Audio name, but Corsair will be the parent company and will distribute the products throughout Asia and North America (two areas that Simple Audio currently does not support).
The back of the Roomplayer I is much more interesting as it has a 50 watt amplifier built-in so it can power speakers independently.
The Roomplayer solutions are apparently quite easy to hook up and their output is very clean (supports up to 24 bit sound natively). As the average consumer is becoming more and more comfortable with setting up a home network, this is an opportunity for both Corsair and Simple Audio to market these products in new regions where overall market penetration of networked home audio is still quite low.
Corsair is a very, very aggressive company when it comes to entering new markets. Their power supplies and cases are perfect examples of how they tend to do business. Corsair actually produces neither of those product lines, but instead relies on contract manufacturing to handle production. What Corsair certainly appears to do well is specify these components very well and handle end product quality control. There really are few overall complaints about Corsair and their products, and as a consumer I do hope that they have another good one on their hands.
The sales numbers will of course be key, and obviously Corsair feels comfortable enough with Simple Audio and their products to buy them up. We are not certain when we expect to see the Simple Audio products on store shelves, but Corsair typically does not screw around.
Now we only have to wonder, "Who is next on Corsair's radar?"
ASUS RT-N56U Wireless Router Review
On deck for review today is the ASUS RT-N56U “Black Diamond” Dual-band Gigabit Wireless-N Router. ASUS has a broad stable of networking equipment including wireless adapters, wireless routers, wired networking gear and even some power line networking gear. Released in late 2010, the RT-N56U is one of the lower cost offerings in ASUS’ Dual Band N series and can be found online for around $99.
ASUS RT-N56U Wireless-N Router Overview
The media review information supplied to us by ASUS claims the ASUS RT-N56U “Black Diamond” offers “Extreme performance in style.” The router’s “Aesthetic design” has a “Sexy and stylish approach with streamlined, meticulously designed and well-rounded appearance, just like diamonds sparkling and twinkling in the dark.” Now I don’t know about you, but if it’s dark, I’m not sure how you see diamond’s twinkling? But I digress; the RT-N56U is a great looking router, with the black cross hatched lattice surface we liked from previous ASUS routers.
Amped Wireless R20000G and UA2000 Introduction
Continuing with our networking adapter and router reviews, today we have a pair of devices on tap from a relative newcomer to the home and office networking field, Amped Wireless. Founded in 2007, they began selling Wi-Fi products in 2010. In those 2 years they’ve already pushed out a wide array of Routers, Range Extenders, Access Points, USB Adapters and Antennas/Boosters. While they don’t have the history of Cisco, Netgear or D-Link, it’s great to see new companies entering the fray as more competition can only benefit the consumer.
Today we’re looking at their flagship High Power Router, the Wireless-N 600mw Gigabit Dual Band R20000G as well as one of their leading USB adapters, the High Power Wireless-N Directional Dual Band UA2000. List price for the router and adapter is $169 and $99 respectively, but the router and adapter can be found online for about $10 less each at Newegg.

Intel's new Crystal Forest chipset includes an undisclosed embedded CPU, an 89XX-series chipset and their Data Plane Development Kit which is the SDK they've created for designing fast path network processing. This is not a competitor to AMD's Freedom Fabric which is designed for communication within a large series of processing nodes, instead you will see Crystal Forest powering high end routers and web appliances. Intel has designed this new chipset to increase the performance of cryptography and compression on network packets and claims it will increase speed as well as security, along with the benefits of support coming directly from Intel. The Inquirer reports a long list of vendors who have signed on, including Dell, Wind River Systems and Emerson Network Power.
"CHIPMAKER Intel has launched its Crystal Forest chipset for network infrastructure.
Intel might be best known for its X86 desktop, laptop and server chips but the firm does a pretty good trade in embedded chips and has announced that a number of large vendors have pledged their support for its new Crystal Forest chipset. The firm said its Crystal Forest chipset will enable networking equipment vendors to shift and control more data using its chips."

Some computer components get all the glory. Your normal lineup of FPS crushing GPU’s, Handbrake dominating CPU’s, and super-fast Memory end up with most of the headlines. Yet behind the scenes, there are some computer components we use that are pivotal in our use and enjoyment of computers and receive very little fanfare. Without networking we wouldn’t have file sharing, LAN parties or even the Internet itself. Without routers and network adapters, we wouldn’t have networking.
ASUS recently sent a whole slew of networking components our way and we’ve decided to take them for a spin and see if they’re worth your hard earned dollars. Our box of ASUS goodies included:
- ASUS RT-N66U Gigabit Router – Dual Band Wireless-N900
- ASUS PCE-N10 - Wireless N PCI-E Adapter Wireless-N
- ASUS PCE-N15 - Wireless N PCI-E Adapter Wireless-N
- ASUS USB-N53 - Dual Band Wireless N Adapter
- ASUS USB-N66 - Dual Band Wireless-N900 Adapter
Without further ado, let’s jump in and tackle each one.
ASUS RT-N66U Gigabit Router – Dual Band Wireless-N900
Routers are one of those components that most of us don’t really think about unless something goes horribly wrong. Most people will buy one they find on a big box store shelf (or even worse, just use their ISP’s router), pull it out of the box, plug a few cables into it and then forget about it in a closet for a few years.
