Big Switch Girds for SDN Battle

In coming out with its first commercial product, Big Switch Networks seems ready to define some battle lines in software-defined networking (SDN).

As expected, the company is promoting a network architecture that uses OpenFlow to program Ethernet switches. As has been fashionable in SDN circles lately, Big Switch is also espousing the idea of a hybrid network -- one where OpenFlow-enabled gear is installed next to traditional routers and switches.
