OpenFlow Test Deployment Options
April 08, 2013
OpenFlow can be introduced into production networks in several ways. I’ll look at two options for deploying OpenFlow that network engineers can use to test the protocol and get their feet wet with SDN.New SDN Technology Challenges VMware, Cisco
April 02, 2013
A new SDN competitor is challenging VMware, Cisco and others. Nuage Networks, an Alcatel-Lucent venture, has announced Virtualized Service Platform (VSP), an SDN technology that employs virtual switches and network overlays.How APIs Transform Data Center Management
March 26, 2013
APIs are helping to usher in new mechanisms for making data center management more automated and scalable. They’re also key to network virtualization and private clouds.VMware's NSX End Game Is Hybrid Clouds
March 15, 2013
NSX, VMware's data center network virtualization platform, is really about public and hybrid clouds, where VMware has plans for growth. Here's why.VMware's Network Virtualization Plans Crystallize in NSX
March 13, 2013
VMware announces NSX, a software platform that combines its vCloud Network and Security software with Nicira's NVP. The combined platform provides network virtualization via vswitches and a centralized controller.SDN: Focus On The Possibilities, Not Just The Technology
March 07, 2013
Software-defined networking is in an enviable position: Everyone is excited about the concept and wants to believe in it. Among networking professionals, expectations are high. But don't make the mistake of looking at SDN as just a new tool to solve yesterday's problems.
are falling into this trap as they seek to market and monetize SDN before the new-car smell wears off. OpenFlow, because it's a standard, is an exception, but we see SDN-like capabilities baked into a number of proprietary and only partially standards-based systems. Sure, most vendors promise to support OpenFlow in addition to proprietary code, but the temptation is strong to "embrace and extend."
As chief architect of the InteropNet and CEO of a technical design company, I understand that it's normal for IT organizations to come at software-defined networking from the perspective of an engineer: What's broken that can be fixed by the ability to program a network to dynamically change its operating mode or parameters via a programmatic method?
Use SDN to make the current network better, sure. But it's more important to think differently about how SDN will help us design and build the network of the future.
Will SDN Kill TRILL?
February 26, 2013
Layer 2 multipathing standards such as TRILL and SPB may seem redundant in an SDN world. But these standards still have a role to play while we wait to see how the SDN market matures.SDN Startup Targets Cloud Providers
February 15, 2013
SDN startup Anuta Networks is launching a controller for IaaS cloud providers to manage physical network infrastructure—switches, routers, load balancers and more—and to automate the provisioning of network services.F5 Acquires SDN Startup LineRate Systems
February 12, 2013
News roundup: F5's LineRate Systems acquisition targets data center programmability, scalability; Dell launches a new switch and rolls out OpenFlow support; CA simplifies IAM offerings; Veeam offers VM backup up to 15 cloud providers.Cisco's ONE Controller Debuts; Targets SDN
February 04, 2013
Cisco's SDN architecture gets its keystone with the launch of the Cisco ONE Controller, a software package that supports OpenFlow and its own onePK APIs. Cisco also announced support for hybrid clouds with its Nexus 1000V product and the Nexus 6000, a new data center switch.
