OpenFlow Control for Cooperating AQM Scheme

摘要：

OpenFlow is defined as a unified control plane and architecture for packet and circuit switched networks. We deal with the congestion control problem in the multi-layer network, and propose a cooperative congestion control scheme for a domain with multiple AQM routers based on the OpenFlow architecture. This scheme operates three different cases in the domain, where the domain server share information with core router and edge router interactively. Moreover, we use the OpenFlow to control atomic behaviors for packet handing within each switching element, which could manipulate such behaviors from a control server, thus users can program their own network behaviors by injecting their own control programs into the server. The congestion control algorithm is simulated to ensure the convergence of the average rate and throughout capacity to its equilibrium state when there are many high-rate flows in multilayer network. Finally, we compared its performance of the dropping probability and the queue length queue length with respect to the single router control results.
