SDN (Software Defined Networking), making the network open and programmable, is considered to be one of the future development trends of the network. The academic institutions started the development of SDN, and today International organizations take the steps to promote its standardizations. As the OpenFlow protocol is the mainstream approach to implement SDN, the latest versions of OpenFloware therefore discussed. Also the standardizations of SDN developed and supported by the International Organizations are introduced in this article. It is believed more promising application and development of SDN can be seen in the near future.
