“The Killer E2500 delivers powerful networking technology to gamers and performance users, including significant new enhancements to its Advanced Stream Detect 2.0 Technology and the all new Killer Control Center. In addition to detecting and optimally prioritizing your games, video, and voice applications with Advanced Stream Detect 2.0 Technology, the Killer E2500 also detects and manages 500+ of the top global websites.”

The networking performance is said to be improved considerably with the new controller and software, with "Lag and Latency Reduction Technology":

KillerE2500_NetworkingPerformanceChart.jpg

“Through its patented technology, Killer is able to get network packets to your applications and web browsers up to 25% faster than the competition during single application usage, and potentially by more than 10x faster when multitasking.”

As I quickly realized when reviewing the Killer Wireless-AC 1535 last year, the software is just as important as the hardware with a Killer adapter. For the new E2500, the Killer Control Center has been re-designed, to provide “users full control of all aspects of their system’s networking performance”.

Rivet Networks describes the functionality of this Killer Control Center software, which allows users to control:

  • The priority of each application and popular website
  • The bandwidth used by each application and popular website
  • The Killer interface that each application is going over
  • The total bandwidth being used by system

I found that enabling the Killer Software bandwidth management to significantly affect latency when gaming (which you can see here, again revisiting the AC 1535 review), and Rivet Networks is confident that this new system will offer even better performance. We’ll know exactly how this new controller and software performs once we have one of the new motherboards featuring this E2500 controller onboard.

Actiontec MoCA WCB6200Q and ECB6200 Review

Occasionally we’ll get some gear rolling through the PCPer offices that are a bit off the beaten path.  The pair of devices on tap today are something you may not come across often, and could very well be something you may not have even heard of.  They are niche products serving a niche need, and that niche is “MoCA.”  Today we’re looking at the Actiontec WCB6200Q 802.11ac MoCA 2.0 Wireless Network Extender and its partner in crime the Actiontec ECB6200 Bonded MoCA 2.0 Network Adapter.

00_MOCA_Network.jpg

So, what the hell is “MoCA” you ask?  “MoCA” stands for “Multimedia over Coax Alliance” and is a standard for running data over in-house Coax wiring.  Whether you know it or not, you may have already run into MoCA networking as it's often used by cable and satellite companies to connect multi-room DVRs.  Established in 2004, the ‘Alliance’ currently has 45 members including pay TV operators, OEMs, manufacturers and IC vendors.  These members came together and developed a standard to create an in-home backbone for wireless network extension, multi-room digital video recorders (DVRs), over-the-top (OTT) streaming content as well as network access in MDU (Multiple Dwelling Unit) environments.  Using unused frequency bands on the Coax cabling, MoCA comes in 3 flavors, MoCA v1.1 that has speeds of up 175 Mbps, MoCA v2.0 was released in 2010 with speeds of up to 800 Mbps, and just recently announced in April of this year, MoCA v2.5 will see throughput of up to a whopping 2.5 Gbps.  Unfortunately, MoCA v2.5 is so new that we’ve not seen any related hardware yet.

So, what does all that actually mean?  Simply put, MoCA is a way for you to easily get high speed network connectivity to areas that you normally couldn’t.  Unless you are lucky enough to have a house with network drops in each room, you are most likely are using wireless to reach the far corners of your house.  But what if you can’t get a good signal somewhere in your home, or you can get a signal, but the throughput just isn’t up to snuff?  This is where MoCA is supposed to help.  You likely already have a ‘hard wire network’ running into every room of your house, and that’s Coax.  Using a MoCA network you can extend your high speed network’s footprint anywhere in your house you have a Coax port.

Introduction

Even before the formulation of the term "Internet of things", Steve Gibson proposed home networking topology changes designed to deal with this new looming security threat. Unfortunately, little or no thought is given to the security aspects of the devices in this rapidly growing market.

One of Steve's proposed network topology adjustments involved daisy-chaining two routers together. The WAN port of an IOT-purposed router would be attached to the LAN port of the Border/root router.

di1.png

In this arrangement, only IOT/Smart devices are connected to the internal (or IOT-purposed) router. The idea was to isolate insecure or poorly implemented devices from the more valuable personal local data devices such as a NAS with important files and or backups. Unfortunately this clever arrangement leaves any device directly connected to the “border” router open to attack by infected devices running on the internal/IOT router. Said devices could perform a simple trace-route and identify that an intermediate network exists between it and the public Internet. Any device running under the border router with known (or worse - unknown!) vulnerabilities can be immediately exploited.

di2.png

Gibson's alternative formula reversed the positioning of the IOT and border router. Unfortunately, this solution also came with a nasty side-effect. The border router (now used as the "secure" or internal router) became subject to all manner of man-in-the-middle attacks. Since the local Ethernet network basically trusts all traffic within its domain, an infected device on the IOT router (now between the internal router and the public Internet) can manipulate or eavesdrop on any traffic emerging from the internal router. The potential consequences of this flaw are obvious.

di3.png

The third time really is the charm for Steve! On February 2nd of this year (Episode #545 of Security Now!) Gibson presented us with his third (and hopefully final) foray into the magical land of theory-crafting as it related to securing our home networks against the Internet of Things.

The Rebel scum known as the LEDE Project have broken away from the OpenWRT project in an unannounced move meant to increase transparency.  Jokes aside, The Register named seven of the developers who are part of this forking, a not uncommon practice in open source projects.  LEDE will try to bring in fresh enthusiasm to a Linux project which has been losing the interest of programmers, perhaps due to the lack of transparency that they cite or possibly just due to waning interest in a long running project.  Pop on over to their page to see their mission statement, rules and processes if you are interested in how they compare to OpenWRT.

Cable Companies Besting DSL For Internet, But Continue Dropping Pay TV Subscribers

Subject: General Tech | December 1, 2015 - 07:30 PM |
Tagged: networking, cable tv, cable isp

A bit before the week of Thanksgiving and Black Friday, I came across a pair of interesting articles (linked below) over at DSL Reports that had some interesting figures for the state of broadband and cable TV. While cable companies continue to rule the roost when it comes to the ISP subscriber side of things, they are also steadily bleeding cable TV subscribers. According to the numbers (which they got from Leichtman Research), the third quarter of 2015 has been simultaneously the worst quarter ever for telcos who lost both internet and cable TV subscribers, it was the best quarter (of least cable TV losses) since 2006.

On the broadband side of things, of the top seventeen providers Leichtman Research provided numbers for, cable companies brought in 787,629 new subscribers while the telephone companies lost 143,338 of their subscribers (likely customers on older forlorn CO-fed DSL tech). Cable companies are maintaining a healthy lead in total subscribers as well at approximately 54 million versus 25 million telco subscribers.

 

Broadband internet subscribers at end of Q3'15
  Subscribers YTD Net Subscribers +/- in Q3
Cable 54,262,565 787,629
DSL 35,246,382 -143,338

Not too bad considering all the bad press the cable companies have thrust upon themselves with, for example, Comcast rolling out 300GB caps across the US and their notorious (or should I say infamous) customer support departments. Somehow only CableOne and WOW lost subscribers in Q3.

At the end of Q3'15 there were 94 million cable television subscribers shared among the 12 top providers (eight cable, two satellite, and two cable). Collectively, the companies lost 190,693 TV subscribers versus last quarter which is an increased loss YoY as well (155,000 in Q3'14). It should be noted that if Dish's Sling TV subscriber numbers are not taken into account, it is a 345,000 decrease in pay TV subscribers.

Cable TV Subscribers at end of Q3'15
  Subscribers Net Subscribers +/- in Q3
Cable 48,809,907 -144,693
Satellite 33,479,000 -3,000
Telephone 11,678,000 -49,000

The cable companies lost 144,693 subscribers in Q3 making it an improvement in that it is the least amount of subscribers lost since 2006. For example, in the same quarter last year the cable companies lost 440,000. Comparatively, the telephone companies only lost 49,000 TV subscribers, but it was their worst quarter yet when it comes to losing TV subscribers. Charter, Direct TV, and Verizon were the only three of the listed companies to actually pick up subscibers this quarter while everyone else lost them.

 What do you think about the numbers? Will the cable beheomouths continue being the dominant source of internet for the US? Will traditional cable/paid TV ever make a comeback, and if not just how many subscribers will these providers have to lose before they embrace new models that support à la carte and even cord cutting/streaming only?

CES 2015: TP-LINK AV1200 3-Port Gigabit Powerline Adapter

Subject: General Tech, Networking | January 6, 2015 - 07:30 AM |
Tagged: tp-link, powerline networking, networking, ces 2015, CES

Powerline networks are not the most popular, especially with advancements in wireless technology, but they are still being actively developed. TP-LINK specifically mentions a few use cases: going through cement or certain soundproof walls, going across metal beams and studs, and going further than is practical under FCC broadcast power limits.

Today at CES, TP-LINK has announced the TL-PA8030 AV1200 Gigabit Powerline networking adapter. This product differentiates itself from previous offerings with “HomePlug AV2 MIMO”, which is an acronym that is normally applied to wireless technology with multiple antennas. It is basically the same thing in this case, because the adapter uses all three prongs.

TPLink-TL-PA8030.jpg

Basically, how electrical sockets work is that you have two main prongs, one of which has an alternating voltage applied to it that averages out to about ~115V RMS over a cycle (relative to the other prong). When that wire is connected to a second one, at whatever is considered “neutral” voltage, it creates an electrical current with that drop (or rise) in voltage. A third plug, which is held at the ground's voltage, takes away any excess buildup from friction, wires that are shorted to the case, and so forth.

For this product, this means that one connection will be on the same circuit as a high-voltage, 60Hz signal, and the other will be mixed with ground noise. Keep in mind, the alternative to powerline networking is broadcasting on unregulated, wireless spectrum, so humanity is not afraid to send a signal through some nasty noise. Still, it is good to stop and think about what these engineers have been able to accomplish: broadcasting two signals, down two really nasty (and in different ways) circuits, and combine them for increased performance with multiple devices.

This out of the way, the specifications themselves are brief: it is three Gigabit (1.2 Gbps total) network connections that communicate through A/C plugs. It is backwards compatible with older TP-LINK HomePlug AV adapters (AV1000, AV600, AV500, AV200, and of course other AV1200s).

No pricing information, but TP-LINK is targeting Q3 2015 for this AV1200.

AMD Demonstrates ARM-Based NFV Solution Using Hierofalcon SoC

Subject: General Tech, Networking | October 11, 2014 - 01:42 AM |
Tagged: sdn, nfv, networking, Hierofalcon, arm, amd

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.

AMD ARM-Based Hierofalcon 64-bit SOC.jpg

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 Readies TEW-818DRU AC1900 Wireless Router

Subject: Networking | March 12, 2014 - 07:56 PM |
Tagged: router, trendnet, gigabit router, gigabit ethernet, ac1900, 802.11ac, 256 qam, networking

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 TEW-818DRU IO.jpg

 

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.
