Big Switch, Avaya, IBM, VMware: SDN Strategies

Part 4 in our series comparing vendors' SDN approaches.

The Big Virtual Switch and Big Tap applications integrate with the controller, and the company’s Switch Light is a software platform for merchant-silicon-based physical and virtual switches within hypervisors.
