Optimal Utility-based Internal Congestion Control in a Cluster-based Router

  • Technical report TR09-12. Optimal utility-based congestion control is an optimization approach to congestion control problems where the objective is to maximize the aggregate source utility over their transmission rates. It has been used to analyze Internet congestion control schemes. In this paper, we develop a discrete congestion control scheme to manage congestion internal to a cluster-based router. We simulate our proposed scheme with ns-3 and also evaluate this scheme in our cluster-based router prototype. Our results show that it is a very effective approach to improve the overall forwarding rate of the router by reducing the injection rate of traffic to the internal network when the router is under heavy load. | TRID-ID TR09-12
