After several years of research, Software Define Networking (SDN) has finally become a reality. At this year’s Open Networking Summit, Google announced it had already deployed its own SDN design in the backbone network that interconnects all its Data Centers. NTT and Verizon hinted that they’d deploy SDN soon, while network equipment vendors indicated they were committed to the concept. IT executives and managers are also taking notice. One pundit predicted a ‘new epoch’ in networks based on SDN- for data centers, campus networks and WANs. But what exactly is SDN and the associated OpenFlow protocol that the Open Networking Foundation (ONF) is standardizing?
The term SDN has been redefined from the 1980s and 90s where it was used by AT&T and other telcos to denote a VPN for digital circuit switched and private line WANs. SDN now applies to the control of IP routed and Ethernet switched networks. Key SDN concepts include the separation of the data and control planes, the existence of a centralized controller with an overarching network view, and the ability for external apps to program the network. Why is that so profound and what are the advantages to be realized?
Meanwhile, the OpenFlow protocol is said to increase network functionality while lowering operating costs through simplified hardware, software, and management. How is that possible? ComSocSCV has lined up the world’s top two speakers on each of these topics to describe and discuss SDN, OpenFlow along with research projects and ONF standardization activities. The two 45 minute presentations will be followed by a lively panel session and audience Q & A moderated by the IEEE ComSocSCV Chair.
