In conventional multicast communication, the source carries a singleconversation with all destination nodes. If a node on the path to any destination becomes congested, the throughput to all destinations is reduced, thus treating some destination nodes unfairly. We consider a window-controlledmultipoint connection and study the use of destination set grouping, where thedestination set can be split into disjoint subgroups with the source carrying independent conversations with each subgroup. We present a static grouping heuristic that can obtain near optimum grouping for static network environmentsand a dynamic grouping protocol which can adjust the grouping and the window sizes per group in response to changing network conditions. The performance ofthe static grouping heuristic and the dynamic grouping protocol are studied using simulation and compared with single-group multicasting.
