Flexibility and extendibility of Software Defined Networks allows development of diverse network management and flow monitoring techniques. Yet, there are inherent tradeoffs between the quality of flow monitoring and the required network resources. In particular, collecting flow statistics, at the level of specific source-destination addresses (and, moreover, specific protocols and ports), requires...
This paper proposes a distributed algorithm that aims for congestion control in Software Defined Networking with distributed controllers by exploiting loop structures in a network and coloring. Our algorithm dissects a network into loop units called tie-sets and updates flows on edges by enclosed calculation in each controller, which is in charge of one of loop units. Additionally, the deployment...
