In this video, Nick McKeown from Stanford presents: How SDNs Will Tame Networks.
Networks are notoriously hard to debug. Today, we only have a rudimentary set of tools available, such as ping, traceroute, tcpdump, and netflow. These tools try to reconstruct the distributed state of the network in an ad-hoc fashion, while the state is being constantly changed by a variety of complex distributed protocols. Software-Defined Networks (SDNs) make it possible – for the first time – to verify, validate, and even prove that the network is behaving correctly. SDN provides the opportunity to rethink how we write network control programs, from the development of control programs all the way to their deployment in production networks.”
