Title: A Utility Maximizing Rate Control Algorithm in Multicasting Networks
Abstract: In this paper, we address the optimal resource allocation problem in networks with unicast and multirate multicast sessions. With the purpose of maximizing the aggregate user utility, we use a unified convex program formulation to integrate unicast and multicast sessions into a common framework, keeping in mind the heterogeneity of the multicast sessions. By applying a penalty function approach, a heuristic rate control algorithm is derived. Simulation results show that the algorithm guarantees the fair coexistence of TCP-based unicast sessions with multirate multicast sessions. It is also shown that various fairness criteria of resource allocation could be achieved by choosing appropriate utility functions, and resource-utilizing efficiency would be likewise different.
