EVPN vs PBB-EVPN

The is the next in a series of technical posts relating to EVPN – in particular PBB-EVPN (Provider backbone bridging, Ethernet VPN) and attempts to explain the basic setup, application and problems solved within a very large layer-2 environment. Readers new to EVPN may wish to start with my first post which gives examples of the most basic implementation of regular EVPN;

EVPN – the basics

Regular EVPN without a doubt is the future of MPLS based multi-point layer-2 VPN connectivity, it adds the highly scalable BGP based control-plane, that’s been used to good effect in Layer-3 VPNs for over a decade. It has much better mechanisms for handling BUM (broadcast unknown multicast) traffic and can properly do active-active layer-2 forwarding, and because EVPN PE’s all synchronise their ARP tables with one another – you can design large layer-2/layer-3 networks that stretch across numerous data centres or POPs,  and move machines around at layer-2 or layer-3 without having to re-address or re-provision – you can learn how to do this here;

EVPN Inter-VLAN routing + mobility

But like any technology it can never be perfect from day one, EVPN contains more layer-2 and layer-3 functionality than just about any single protocol developed Continue reading

NFD13 Forecast – Cloudy With a Chance of Software

Well, this week is a week of firsts — or at least, firsts in a while. It’s my first time actually posting something new on the blog in a while, and it will also be my first Tech Field Day event in a while.

I’m honored to have been invited back to NFD13, happening on Thursday, 11/17 and Friday, 11/18. I’m very excited to be joining the TFD team for another event! The delegate panel includes some of the most experienced and well respected names in the networking industry (myself excluded, obviously), and the sponsor list is really quite exciting. I’m looking forward to seeing some old friends, and making some new ones along the way.

I really like when NFD events have a mix of focuses (foci?). It keeps the conversation varied and interesting for both the delegates and the audience. For NFD 13, I see several big themes for the sponsor list:

Data Center Fabric/Automation/Orchestration

Network Testing/Modeling/Audit/Management

Software Defined WAN

Note: I could be mis-classifying a couple of Continue reading

Reprisals against Apple in a U.S.-China trade war would be indirect

If the Chinese government retaliated against tariff increases by the United States, it would not take direct aim at Apple, an economist argued today."For China, the best target is Boeing," said Caroline Freund, a senior fellow at the Peterson Institute for International Economics.Freund was responding to questions after Global Times, a Chinese Communist Party-supported newspaper, warned of reprisals if President-elect Donald Trump follows through on a campaign pledge to dramatically increase tariffs on goods imported into the United States.To read this article in full or to leave a comment, please click here

Worth Reading: Can Technology be Morally Neutral?

“Technology is neutral. It’s only how it’s used that can be good or bad.” Back in the 1960s and even up to the 1970s, a statement along those lines was often the standard response you got from an engineer or scientist if you raised questions about the dangers or moral implications of a given invention. The neutrality argument was used to defend radio, television, computers, and even nuclear energy. But Sheila Jasanoff, for one, would disagree. —MercatorNet

IDG Contributor Network: Smartphones cause insomnia, study finds

Put that smartphone away or limit your use of it if you want to get a decent night’s sleep and stay healthy.Researchers from the University of California, San Francisco say they have confirmed that sleep deprivation is magnified by exposure to a kind of blue light emitted by the devices. And missing sleep can instigate deadly diseases, such as obesity and depression.“Longer average screen-time was associated with shorter sleep duration and worse sleep-efficiency,” the journal PLOS ONE says of the research on its website.Sleep took longer to come on and quality was generally poor, according to the researchers.To read this article in full or to leave a comment, please click here

Troubleshooting High CPU Usage On Cisco Nexus 7000

Intel Sets Up Skylake Xeon For HPC, Knights Mill Xeon Phi For AI

With the “Skylake” Xeon E5 v5 processors not slated until the middle of next year and the “Knights Landing” Xeon Phi processors and Omni-Path interconnect still ramping after entering the HPC space a year ago, there are no blockbuster announcements coming out of Intel this year at the SC16 supercomputing conference in Salt Lake City. But there are some goodies for HPC shops that were unveiled at the event and the chip giant also set the stage for big changes in the coming year in both traditional HPC and its younger and fast-growing sibling, machine learning.

Speaking ahead of the …

Intel packs more horsepower in its monster 22-core processor

CPU performance increases were ignored for years, but AMD put them back on the map with its upcoming Zen chip. This has rubbed off on Intel in a good way.Intel's taken its fastest server chip, the top-line 22-core Xeon E5-2699 v4 chip, and made some tweaks to squeeze out more CPU performance. It has created a new chip called the 22-core Xeon E5-2699A v4, which is about 5 percent faster.While 5 percent may sound like a small number, it's big for those installing thousands of servers running on the chips. Four-socket servers can have up to 88 CPU cores and run up a 20 percent gain in performance improvements.The new chip could also be used in workstations with the latest GPUs to create VR content or run engineering applications like SolidWorks.To read this article in full or to leave a comment, please click here

Intel’s latest Xeon chips based on Skylake due next year

Intel has moved to a new architecture called Kaby Lake for its PC chips, but it isn't done with the previous generation Skylake yet. The company will release new Xeon server chips based on Skylake in mid-2017, and they will boast big performance increases, said Barry Davis, general manager for the accelerated workload group at Intel. The Skylake Xeon chips will go into mainstream servers and could spark a big round of hardware upgrades, Davis said. Xeon chips aren't as visible as Intel's PC chips but remain extremely popular. Companies like Google, Facebook, and Amazon buy thousands of servers loaded with Xeon chips to power their search, social networking, and artificial intelligence tasks.To read this article in full or to leave a comment, please click here

iPhones in China are randomly shutting down, owners say

A consumer protection group in China is asking Apple to investigate problems with iPhone 6 and iPhone 6s units automatically shutting off.Recently, iPhone customers in the country have been complaining about the problem to the China Consumers Association, the group said in a statement on Tuesday. The shutdowns occur when the phone’s battery charge drops to between 60 and 50 percent.The problem will persist despite upgrading to the latest version of iOS. It will also occur in both cold environments and at room temperature.  After the automatic shutdown, the phones will also fail to turn on without connecting to a power supply.To read this article in full or to leave a comment, please click here

Super Mari-owned: Startling Nintendo-based vulnerability discovered in Ubuntu

A vulnerability in a multimedia framework present on Version 12.04.5 of Ubuntu can be exploited by sound files meant to be played on the venerable Nintendo Entertainment System, according to security researcher Chris Evans. The vulnerability is the result of a flaw in an audio decoder called libgstnsf.so, which allows gstreamer Version 0.10 to play the NSF files that the NES uses for music. NSF files, when played, use the host system’s hardware to create a virtualized version of the NES’ old 6502 processor and sound hardware in real time. +ALSO ON NETWORK WORLD: Cool Yule Tools 2016: Digital disruption at Santa's Workshop + Android deems Instagram worthy of its presenceTo read this article in full or to leave a comment, please click here
