A rate adaptation algorithm for multicast sources in priority-based IP networks

This article presents a new rate adaptation algorithm for multicast sources that operate in priority-based IP networks. The algorithm represents the flow control component of our work on an architecture for video multicasting in priority-based IP networks. We show (through simulation results) that the algorithm meets our design goal of satisfying the quality of service (QoS) requirements of different video multicast receivers which have different networking capabilities.
