Worth Reading: The TCP Tortoise

As LinkedIn migrated to serving its pages on HTTP/2 earlier this year, it became imperative that we identify and use the most optimal transport layer strategy for our users’ network. Being a Transmission Control Protocol-centric (TCP) infrastructure, we initiated an effort to study the effects of different TCP congestion control strategies in different geographies. We found that with the right strategy, we could significantly improve our site speed, resulting in up to 7% faster content downloads. —Prasanna Vijayanathan @ Linkedin

The new Extreme Networks is off and rolling

The story of Extreme Networks is one of the more remarkable turnarounds I’ve seen in technology in years. About two years ago the company had a market cap of under $300 million, and I thought they were a sure-fire acquisition target for someone who wanted some decent technology on the cheap — because it was becoming apparently clear that the once-cool networking company had lost its way like so many others before it.Many of the brand names we have known in the past — Nortel, 3Com, Cabletron, Lucent, FORE systems and Foundry — all dropped as Cisco got bigger and HP Networking gobbled up the low end. There just didn’t seem to be room for another vendor. If an acquisition happened, it would likely fall on the scrap heap that so many other networking vendors have been tossed on.To read this article in full or to leave a comment, please click here

How Hardware Drives The Shape Of Databases To Come

One of the reasons that the University of California at Berkeley was been a hotbed of software technology back in the 1970s and 1980s is Michael Stonebraker, who was one of the pioneers in relational database technology and one of the industry’s biggest – and most vocal – shakers and movers and one of its most prolific serial entrepreneurs.

Like other database pioneers, Stonebraker read the early relational data model papers by IBMer Edgar Codd, and in 1973 started work on the Ingres database along IBM’s own System R database, which eventually became DB2, and Oracle’s eponymous database, which entered …

Hadoop Platform Raised to Knights Landing Height

It would be surprising to find a Hadoop shop that builds a cluster based on the high-end 68+ core Intel Knights Landing processors—not just because of the sheer horsepower (read as “expense”) for workloads that are more data-intensive versus compute-heavy, but also because of a mismatch between software and file system elements.

Despite these roadblocks, work has been underway at Intel’s behest to prime Knights Landing clusters for beefier Hadoop/MapReduce and machine learning jobs at one of its parallel computing centers at Indiana University.

According to Judy Qiu, associate professor of intelligent systems engineering in IU’s computing division, it is …

IDG Contributor Network: SDN and a life beyond the death of the internet

For decades, enterprises have relied on the public internet for business-critical SaaS applications and data traffic. The reason why is pretty simple: it’s cost-efficient, it’s easy to use and it’s already there. Compare that to the logistical, financial and implementation challenges of installing an alternative private network, and it’s clear why enterprises have been pretty content with the internet for their entire digital lives.But, it’s 2017. And, if there’s one thing clear about the public internet today, it’s that it no longer cuts it. Rampant DDoS attacks and other cyber threats posed by hackers, rogue employees and nation-states have not just revealed the security, reliability and transparency cracks in the public internet — they’ve blown them wide open.To read this article in full or to leave a comment, please click here

SecureNet: Simulating a Secure Network with Mininet

I have been working with OpenStack(devstack) for a while and I must say it is quite convenient to bring up a test setup using devstack. At times, I still feel it is an overkill to use devstack for a quick test to verify your understanding of the network/security rules/routing etc. This is where Mininet shines. … Continue reading SecureNet: Simulating a Secure Network with Mininet

NSX-Powered Credit Union Shifts Focus to Speed and Innovation

Personal banking sure isn’t what it used to be. Thankfully.

When is the last time you went to a bank? My trips are so infrequent that I actually enjoy the experience as a change of pace. That’s because normally, I get to transfer money or deposit a check not only online, but from my phone. And things in the banking sector aren’t slowing down, they’re speeding up, as new digital upstarts create competition and a pressure to innovate and make customers’ lives easier.

Still, not too long ago, the banking industry was still feeling the shockwaves of the financial crisis. Investments across the industry were tight, meaning more had to be done with less – a story many of us who have had roles in IT can relate to. So when Amy Hysell took on the role of CIO at the Arizona Federal Credit Union (AZFCU), she decided to take a fresh approach. To compete in this fast-moving industry, she stepped back and took a look at on how to enable speed and innovation, while keeping security as the top priority, and also without sacrificing cost efficiency.

Fast forward to today, and a peek at some of AZFCU’s services quickly Continue reading
