As virtual switch and Open vSwitch (OVS) technology increasingly become the heart of SDN-based data center networks, the challenge for vSwitch vendors becomes finding ways to meet rapidly growing performance challenges. 6WIND is among those working to find ways to optimize OVS. They recently announced extensions to their SDN networking software designed to provide a 10x performance improvement over standard virtual switches.
In this video, 6WIND executives Eric Carmès and Charlie Ashton discuss how they’ve enhanced the company’s 6WINDGate networking software to address OVS scalability issues in SDN environments. The video takes a look at how SDN changes in the data center are increasing the performance challenges for OVS and similar vSwitches, and how 6WIND approached the problem.
6WIND developed its virtual switch acceleration by reusing the architecture concepts of 6WINDGate based on the separation of the data plane and the control plane. Their OVS acceleration solution, with full OpenFlow compatibility, removes the performance bottlenecks of a standard virtual switch while giving it the ability to scale linearly on a large number of cores. Targeted for use in cloud and telecom data centers, the Open vSwitch acceleration solution is designed to address critical scalability challenges.
The 6WINDGate extensions provide network administrators with the ability to deploy larger numbers of virtual machines per blade, leading to significant reductions in CAPEX and OPEX. Company officials expect compatibility with standard OpenFlow controllers will speed adoption of their software in enterprise, cloud and telecom applications.
