Prof Nick McKeown recently presented a talk on Software Defined Networks (SDN) at GigaOM Network’s Structure 2010 conference. One main thesis of SDN is the separation of control logic from forwarding logic; control logic running externally to the high-speed forwarding logic makes the decisions about how and where network traffic is forwarded. This allows new services and routing algorithms to be deployed by upgrading only the control software; the forwarding elements can remain unchanged.
