Abstract
The present invention broadly contemplates addressing QoS concerns in overlay design to account for the last mile problem. In accordance with the present invention, a simple queuing network model for bandwidth usage in the last-mile bottlenecks is used to capture the effects of the asymmetry, the contention for bandwidth on the outgoing link, and to provide characterization of network throughput and latency. Using this characterization computationally inexpensive heuristics are preferably used for organizing end-systems into a multicast overlay which meets specified latency and packet loss bounds, given a specific packet arrival process.
