COT: Consistent Optimized and Trustworthy SDN


Software defined networking (SDN) brought new interesting challenges by externalizing the task of controlling the network to some generic computer software. In particular, the controller software can modify the network routes by introducing new forwarding rules and deleting old ones at a distributed set of switches, a challenge that has received lots of attention in the last six years.
