Amajor recent development in computer networking is the emergence of Software Defined Networking(SDN),whose goal is to provide a centralized,programmable control plane that is decoupled from the distributed data planes on individual network devices.In particular,the development of OpenFlow has demonstrated many potential benefits of SDN,and multiple vendors have started to offer commercial switches supporting the OpenFlow standard.Researchers have also made progress on SDN components including SDN controllers,
Amajor recent development in computer networking is the emergence of Software Defined Networking （SDN）, whose goal is to provide a centralized, program- mable control plane that is decoupled from the distributed data planes on individual network devices. In par- ticular, the development of OpenFlow has demonstrated many potential benefits of SDN, and multiple vendors have started to offer commercial switches supporting the OpenFIow standard. Researchers have also made progress on SDN components including SDN controllers, switches, programming interfaces, verification and de- bugging tools,
