| 摘 要： | 组播网络的异构性问题导致了组播内部公平性问题。本文在分析了相关工作的局限性之后，提出了一种基于效用的单速率组播内部公平性标准，其优化目标是最大化组播会话的净收益。相应地设计了一种基于动态规划的速率控制与修剪算法，该算法在计算开销与通信开销两方面都是可扩展的。

| Abstract: | A multicast session may involve a large number of receivers with heterogeneous data reception capacities, this leads to the inter-receiver fairness problerru Unlike the previous inter-receiver fairness criteria, a utility based fairness criterion is proposed. Both rate control and pruning are considered to maximizing the net benefit of the multicast session, and a dynamic programming algorithm is proposed. The algorithm is scalable both on computation and communication complexity. |
