It means you can't use "network" protocols to make intelligent decisions about applications any more. Back in 2000 (or 2001, I forget exactly), I got to test a variety of bandwidth management appliances. Oh, they were the bomb back then - able to identify (and classify) applications b...
In reviewing some opportunities for Plexxi this week, I was reminded that we have made things very hard on ourselves. Through no one’s fault but our own we have created monsters of networks that are impossible to maintain, debug, diagnose and understand. I have been lucky in my career...
London, 1 May 2014 - The Kenton Group is to offer 100G networks with SDN / NFV to its European and Middle East customer base following a landmark agreement with Cyan (NYSE: CYNI), a leading provider of software-defined networking (SDN) and packet-optical transport solutions (P-OTP) for...
There’s a running meme in networking that has caught a lot of momentum with SDN: abstraction. Just about every vendor these days has bold ambitions to abstract out the complexity. There are APIs, abstraction layers, and architectural shims that all aim to hide complexity from the user....
From a cost perspective, the networking dialogue is dominated by CapEx. Acquisition costs for new networking gear have historically been tied to hardware, and despite the relatively recent rise of bare metal switching, networking hardware remains a high-stakes business. But SDN is chan...
We've talked before about the bifurcation of the network, which is driven as much by the evolution of network services from "nice to have" to "critical" as it is by emerging architectures. The demarcation line in the network stack has traditionally been - and remains - between layers 3...
Integra recognized for innovation in Software Defined NetworkingREDWOOD CITY, Calif - April 22, 2014 - For the second year running Openwave Mobility, a software innovator enabling operators to manage and monetize mobile data, has won the Excellence in SDN Award for Integra - the indust...
Earlier this week, Ethan Banks wrote a very nice article about Mellanox’s dual spine and leaf network in support of a large amount 10GbE access ports. After describing the scaled up network design, he reviews 8 observations about the design, not to point out good or bad, but merely to ...
OpenStack. OpenDaylight. SDN. Cloud. It's all about abstraction, about APIs and "software-defined" (which really means software-controlled, but this is neither the time or place to get into that debate). It's about jailbreaking the network. Enabling access to features and functionalit...
Despite claims that there exists (or will, look out!) a mythical "god box" for the enterprise data center, capable of performing every data center function imaginable, it remains, well, mythical. Efforts to effectively secure the data center and the applications it delivers therefore r...
University aims to dramatically increase network performance and resilience to support 25,000 students across four campuses through infrastructure upgradeBracknell, UK - 11 April, 2014: The University of Westminster, one of London's largest and most respected higher education instituti...
In any space, there is a very small vocal minority. Most people lack the time, interest, or even confidence to say what they think in public. So we are left with a vocal few who drive the conversation. In networking, the vocal minority consists mainly of the vanguards for change. For t...
New OneConnect OCm14000-OCP Adapters Maximise Application Performance with RDMA, Support Overlay Networks for the Cloud and Enable SDN with Open Programmable APIs INTEROP, LAS VEGAS and COSTA MESA, Calif, 1 April 2014 - Emulex Corporation (NYSE:ELX), a leader in network connectivity, m...
The term "service chaining" hasn't quite yet made it into the mainstream IT vernacular. It's currently viewed as a technical mechanism for directing packets, flows or messages (depending on where you sit in the network stack) around the network. Service chaining is the answer to "how ...
It has been over four years since Telia Sonera Sweden and Finland launched the world’s first commercial LTE networks and ushered in the age of true mobile broadband services.  By the end of 2014 we expect there to be nearly 300 LTE networks serving upwards of 300 million use...
Many IT teams are looking at virtualization in the Cloud where enterprise-level storage is kept in “pools” often hosted by vendors who specialize in virtual storage. Most commonly, the data and additional space is accessed via a web-based API. Coraid offers a unique storage management ...
One of the most common phrases heard when new technology is introduced is that it's going to "bridge the gap" between X and Y. X and Y are almost always one of three IT groups: development, operations and networking. And while that goal is admirable (and indeed there are techno-cultura...
Tuesday 25 March, 2014 Flexible, scalable, Open Source Infrastructure as a Service (IaaS) used by organizations such as Zynga, Datapipe, and ISWest, among others, for creating, managing, and deploying public, private, and hybrid Cloud Computing environments Forest Hill, MD --25...

Proponents of pure software infrastructures often point to rapid provisioning (like right now, push a button and blam! Instant scale) as one of the reasons to "go software." Superficially this is true. If your infrastructure is all software (or virtual, if you prefer) then when you nee...
Google’s pursuit of self-driving cars has been well documented over the years. The promise of fleets of self-driving vehicles that could potentially make driving safer while simultaneously shortening commute times makes it one of the most attractive futures technologies around. But whe...
LIn 1974 a specification was developed that would, eventually, launch what we know of as "The Internet." That specification was TCP and though it is often overshadowed by HTTP as the spark that lit the fire under the Internet, without TCP HTTP wouldn't have a (transport) leg to stand o...
#sdas #webperf New TCP algorithms and protocols in a platform net improved performance for apps The original RFC for TCP (793) was written in September of 1981. Let's pause for a moment and reflect on that date. When TCP was introduced applications on "smart" devices was relegated to...
If the future of federated controllers is based on service layering, then how do multiple controllers manage the same device? Is there a requirement for state synchronization? Do they share information about device operation or configuration? Is there a need for controllers that are ma...
As SDN moves closer to large-scale deployments, the issue of controller scaling is becoming a hotter topic. The consensus seems to favor some form of distributed cluster environment, likely in the form of federated clusters. But how should these federations be formed? The first thin...
A lot of security-minded folks immediately pack up their bags and go home when you start talking about automating anything in the security infrastructure. Automating changes to data center firewalls, for example, seem to elicit a reaction akin not unlike that to a suggestion to putting...
What started out as a mechanism to program flows into network switches and routers in a standard way is evolving into a full blown forwarding engine programming and management specification. In the latest version of the spec (1.4, released in October 2013), the abilities exist to confi...
It is human nature to try and relate new information and new ways of doing things to something that we know, something we are familiar with. Often when we talk about the way we fit traffic onto a Plexxi mesh network, the reaction is “I know what you mean, you are doing traffic engineer...
Estimates based on reports from Google put the number of daily activations of new Android phones at 1.3 Million. Based on reported data from Apple, there are 641 new applications per day added to the App Store. According to Cisco's Visual Networking Index, mobile video now accoun...
