Q&A: Building a Layer-2 Data Center Fabric in 2016

One of my readers designing a new data center fabric that has to provide L2 transport across the data center sent me this observation:

While we don’t have plans to seek an open solution in our DC we are considering ACI or VXLAN with EVPN. Our systems integrator partner expressed a view that VXLAN is still very new. Would you share that view?

Assuming he wants to stay with Cisco, what are the other options?

US Supreme Court leaves gap in Samsung-Apple patent ruling

The U.S. Supreme Court on Tuesday ruled in favor of Samsung Electronics and its backers in the industry in a design patent dispute with Apple, when in a 8-0 decision it said that “the term 'article of manufacture' is broad enough to embrace both a product sold to a consumer and a component of that product, whether sold separately or not.”But the top court has left a lot unsaid, including by not providing guidance to the U.S. Court of Appeals for the Federal Circuit on how the damages Samsung has to pay Apple for the infringement of smartphone design patents will have to be calculated. That could also delay for a long time the resolution of the patent dispute between Apple and Samsung, which has already dragged on for a number of years.To read this article in full or to leave a comment, please click here

Facebook, Google, World Wide Technology near top of Glassdoor’s Best Places to Work 2017 list

Depending up on how loosely I define "enterprise technology vendor," I'd say about a third of the 2017 Glassdoor Best Places to Work in the U.S. list consists of companies that supply IT professionals and those they support.Facebook (hey, they sell Workplace collaboration tools) is all the way up to #2, rising from #5 last year, and Google (#4), system integrator World Wide Technology (#5) and Adobe (#9) are all among the top 10. Consulting firm Bain & Co., is #1 for the third time since 2012, and replaces Airbnb as top dog this time around in the 9th annual rankings.To read this article in full or to leave a comment, please click here

Malicious online ads expose millions to possible hack

Since October, millions of internet users have been exposed to malicious code served from the pixels in tainted banner ads meant to install Trojans and spyware, according to security firm ESET.The attack campaign, called Stegano, has been spreading from malicious ads in a “number of reputable news websites,” ESET said in a Tuesday blog post.

Big Switch adds security perimeter around SDN data center

Big Switch Networks today unraveled a wide-ranging group of products aimed at mitigating security attacks, scrutinizing cloud and container environments and improving its existing SDN-based monitoring software. In the security realm Big Switch rolled out its BigSecure Architecture, a high-performance cyber-defense platform that the company says will help enterprises protect against Terabit-speed attack. +More on Network World: 20 years ago: Hot sci/tech images from 1996+ “What we are seeing is network attack by thousands of IoT devices [like the recent Dyn DNS attack that hit 1.2Tbps] using massive speed and bandwidth to take down resources. To mitigate against that kind of attack can be cost prohibitive but what we have implemented in BigSecure can help mitigate those attacks,” said Prashant Gandhi, vice president and chief product officer.To read this article in full or to leave a comment, please click here

Say goodbye to MS-DOS command prompt

My very first technology article, back in 1987, was about MS-DOS 3.30. Almost 30 years later, I’m still writing, but the last bit of MS-DOS, cmd.exe — the command prompt — is on its way out the door. It’s quite possible that you have been using Microsoft Windows for years — decades, even — without realizing that there’s a direct line to Microsoft’s earliest operating system or that an MS-DOS underpinning has carried over from one Windows version to another — less extensive with every revision, but still there nonetheless. Now we’re about to say goodbye to all of that. Interestingly, though, there was not always an MS-DOS from Microsoft, and it wasn’t even dubbed that at birth. The history is worth reviewing now that the end is nigh.To read this article in full or to leave a comment, please click here

Tech Talent Shortage Holding Back Business

Backdoor accounts found in 80 Sony IP security camera models

Many network security cameras made by Sony could be taken over by hackers and infected with botnet malware if their firmware is not updated to the latest version.Researchers from SEC Consult have found two backdoor accounts that exist in 80 models of professional Sony security cameras, mainly used by companies and government agencies given their high price.One set of hard-coded credentials is in the Web interface and allows a remote attacker to send requests that would enable the Telnet service on the camera, the SEC Consult researchers said in an advisory Tuesday.To read this article in full or to leave a comment, please click here

Google says it will reach 100% renewable energy goal by end of 2017

Google in 2012 announced a goal of running its operations 100% on renewable energy. Today the company announced that it plans to meet that target by the end of 2017, a year ahead of schedule.Google will purchase direct renewable energy and buy renewable energy credits that match the amount of power the company uses to power its global operations. That’s 2.6 GigaWatts of electricity, or 2,600 MegaWatts (MW).Google is just one of a handful of vendors, particularly those in the IaaS cloud computing market, who have committed to buying renewable energy to power their operations. Last week Amazon Web Services announced that it plans to be 50% powered by green energy sources by the end of next year.To read this article in full or to leave a comment, please click here

Reaction: Openflow and Software Based Switching

Over at the Networking Nerd, Tom has an interesting post up about openflow—this pair of sentences, in particular, caught my eye—

The side effect of OpenFlow is that it proved that networking could be done in software just as easily as it could be done in hardware. Things that we thought we historically needed ASICs and FPGAs to do could be done by a software construct.

I don’t think this is quite right, actually… When I first started working in network engineering (wheels were square then, and dirt hadn’t yet been invented—but we did have solar flares that caused bit flips in memory), we had all software based switching. The Cisco 7200, I think, was the ultimate software based switching box, although the little 2ru 4500 (get your head out of the modern router line, think really old stuff here!) had a really fast processor, and hence could process packets really quickly. These were our two favorite lab boxes, in fact. But in the early 1990’s, the SSE was introduced, soldered on to an SSP blade that slid into a 7500 chassis.

The rest, as they say, is history. The networking world went to chips designed to switch Continue reading
