Industry Veteran to Lead Company's Drive to Position Itself as the 'Network Provider of Choice to the World's Data Centres' SAN JOSE, Calif - March 11, 2014: Brocade (Nasdaq: BRCD) today announced the appointment of Christine Heckart to the position of Chief Marketing Officer (CMO). ...
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...
One month from today, Plexxi’s Nils Swart and Derick Winkworth will participate in SDNCentral’s DemoFriday to illustrate application abstraction using OpenDaylight. We encourage you to register here and check out the demo on March 14 at 10 a.m. PDT.  In our video of the week, Dan Bachm...
Not entirely unexpected, the optical capabilities in our switch have provoked questions from customers and potential customers on whether the Plexxi solution could be used to create campus, metro or even long distance multi site fabrics. The answer to that question is a resounding yes,...
It’s not clear to me whether there is really a conclusion to a technology trend. I suppose that one trend begets another and that morphs into another. So in some sense, discussing the SDN end game is really foolish. It seems most likely that we all stop talking about SDN in another yea...
We get quite caught up in high level architectures at times. It is good to read some posts that focus on design and implementation and the practicality of taking higher level architectures to reality. Two of Ivan’s posts caught my eye this week. In the first, he discusses the differenc...
I've been following SSL for a long, long time. Since before the turn of the century, in fact. I devised performance tests back in the day that, on at least one system (back when PCI was still the standard method of enabling SSL hardware acceleration) actually melted circuits on the hos...
The biggest difference between high-performance teams and more average teams is that the high-performance group actually acts like a team. That statement is so obvious, I am going to let it stand on its own. If you look at most groups, they tend to act less like teams and more like...
Telecoms system integrators, distributors and telcos have a unique opportunity to partner with Iskratel to deploy a working SDN application, ready for access and flow-based switching immediatelySTOCKHOLM, Sweden and KRANJ, Slovenia. 4 February 2014 At FTTH Conference 2014, Iskratel, on...
NetMatch-S evolves to Cloud environment with the internal adoption of Cloud technologyMilan, February 3rd, 2014 - Italtel today announced the availability of NetMatch-S, the world's first Cloud-inside Session Border Controller (SBC), which uses Network Functions Virtualization (NFV) an...
A newish trend is quietly (comparatively speaking) increasing across the Internets. The basic premise is that end-users aren't being charged for data traversing mobile networks when accessing certain sites, much in the manner users are not charged for calling a company's toll free (800...
We are a few short days away from the biggest spectacle in sports – the Super Bowl. It is impossible to avoid talk this week of Peyton Manning, the Denver Broncos, the Seattle Seahawks, and the NFL in general. But does the NFL have anything to teach tech industries? The NFL is a mas...
#SDAS #SDDC A programmable platform should be more than just lipstick on a CLI The term programmability is, like every other term associated with hype-driven trends, used to describe a wide range of capabilities. In general, when applied to "the network", programmability implies one o...
During a session at Gartner Data Center 2013 (Software Defined Networking? Not a Question of If, A Matter of When and How) the question of SDN adoption was asked by speakers Joe Skorupa and Andrew Lerner of an approximately 100 person audience. These are the (very informal and totally ...
New Adapters Increase Server Virtualisation Density, Connect Hybrid Clouds with Virtual Networks Fabrics, Enable SDN with Open APIs and Optimise Application DeliveryCOSTA MESA, Calif, January 23, 2014 - Emulex Corporation (NYSE:ELX), a leader in network connectivity, monitoring and man...
Last week I walked through the packet formats for VXLAN and NVGRE specifically focused on ways by which the overlay packets provide information to the physical network that help the physical network. Some of the initial extreme thoughts that the overlay and physical network can and sho...
Analyst Joe Hoffman sees Openwave Mobility's Integra platform as a highly scalable solution for networks to optimize and monetize video traffic REDWOOD CITY, Calif- January 20, 2014 - Openwave Mobility, a software innovator enabling operators to manage and monetize mobile data, today a...
By Bob GourleyYou know the top federal IT news of 2013, after all, you probably lived it.  We all tracked topics like the Shutdown and its impact on IT, HealthCare.gov, NSA programs, Data Center consolidation efforts. Every one of those stories have something in common. None of them we...
By Prayson PateWhen discussing innovation, most people focus on advances in technology.  Technology is important, but it is only one of three key components required for innovation.  In order to maximize the opportunity for successful innovation, one must combine the following: A custo...
There have been many articles describing overlay networks in the past few quarters. It's a relatively straightforward concept, not far removed from some of the older VPN technologies very popular a while ago. The actual transport of packets is probably the simplest, it is the control p...
Oracle’s acquisition of cloud-based services company Corente topped the headlines this week. As Mike Bushong noted in a recent post, Oracle’s third cloud acquisition and pursuit of SDN pushes the company into closer competition with Cisco. Both IT giants are looking to expand their mar...
With SDN top of mind (or at least top of news feeds) of late, it's natural to wonder how F5's architecture, Synthesis, relates to SDN. You may recall that SDN -or something like it - was inevitable due to increasing pressure on IT to improve service velocity in the network to match th...
Why is it that the definition of SDN continues to get debated? I think the definition of SDN remains a bit squishy. And while I am not entirely certain that it matters (people shouldn’t be buying SDN; they should be building networks), it is an interesting phenomenon, and understand...
As we embrace 2014, it’s important to focus on emerging trends to predict any industry changes this year and in the coming years. Mike Bushong reviewed 2013 on the Plexxi blog and noted important events that will likely carry into this year, including how 2013 initiated SDN deployments...
From a news perspective, a year is defined by the stories that make headlines. But markets are frequently moved more by subtext than overt story. Its sometimes the less sexy and more subtle happenings at the fringe of media interest that determine how industries will evolve and ultimat...
Sports fan strategists like to throw around the famous Wayne Gretzky quote: I skate to where the puck is going to be, not where it has been. The corporate implications of the quote are self-evident: plot your strategic course to where you think the market is going. Setting your sights ...
We still see quite a few eyebrows raised when we explain how we use WDM optics in our datacenter solution. In the various descriptions of the Plexxi solution it is often mentioned and referred to, but it is worth explaining what that optical infrastructure actually looks like and why i...
The white box switching movement appears to be gaining some momentum. For some, it is a fait accompli that hardware and software will be meaningfully separated, allowing users to procure each independently in a model that more closely resembles what happens on the server side. The fire...
Earlier in 2013 when discussing the evolution of application delivery and F5 I posed a question to which, at the time, didn't have an answer. It was simply "What's Next?" As the time has gone by, the answer to that has become clear. What's next is an evolutionary step in the history...
