CoopRED: Cooperative RED for software defined networks

Recently, Internet is an essential part for human life, and several problems lead Future Internet. Software Defined Networks (SDN) is a representative approach in Future Internet. We propose Cooperative Random Early Detection (CoopRED) to avoid inefficiency in core routers when incoming traffic generates congestion.

Our scheme selects packets that will be dropped in the bottleneck link, and drops them early in the edge router. We conducted simulation to measure the performance, and it shows that the proposed scheme improves the efficiency of core networks.
