Big Switch Networks

Top Executive: Guido Appenzeller, Co-Founder, CEO

Location: Mountain View, Calif.

Big Switch has become the top dog of SDN startups since VMware bought Nicira. It uses the OpenFlow switching and communications protocol, which handles packet routing on a software layer separate from the network’s physical infrastructure. The company recently launched Switch Light, an open-source thin switching platform.
