Each camp believes in software-defined networking, but one will go open source and the other will fight to hold ownership of the networking world by going proprietary. The open source camp is home to software-defined networking (SDN) vendors that believe in placing the brains of a network in centralized software, which will control underlying commodity hardware using the OpenFlow standard. In this camp, companies like NEC and Big Switch will build networks based on commodity hardware. They hope to see the emergence of an ecosystem of third party applications that run on top of OpenFlow controllers and bring about new kinds network services, including granular QoS and mobility management. The most radical player in this camp is Nicira, which offers virtual switches (vSwitches) that can be woven together in a unified fabric running over any physical network. While Nicira's switching software isn't open source, its ... Access >>>
