Software defined networking (SDN) and OpenFlow as the outcome of recent research and development efforts provided unprecedented access into the forwarding plane of networking elements. This is achieved by decoupling the network control out of the forwarding devices. This separation paves the way for a more flexible and innovative networking. While SDN concept and OpenFlow find their ways into commercial...
In this paper, a novel and optimized virtual optical network (VON) composition method, aware of the impact of physical layer impairments (PLIs), is investigated. VONs are composed using Mixed Integer Linear Programming (MILP), which can provide optimal solutions for VON composition. The quality of the composed VONs is verified by adopting an analytical assessment model of PLIs. In order to improve...
