| 摘 要： | 组播拥塞控制是设计组播协议的关键问题之一。提出了一种基于速率的 ,由接收者和发送者混合驱动的组播拥塞控制机制 (RBMCC)。组播拥塞控制机制中由接收者计算本地丢失率、中间节点聚集反馈报文、发送方计算TCP友好发送速率 ,并最终实现对网络拥塞的快速、准确响应。仿真试验证明 ,组播拥塞控制机制具有良好的可伸缩性与满意的公平性

| Abstract: | Multicast congestion control mechanism is one of the key problems in the designing of multicast protocols. A multicast congestion control mechanism, i.e. RBMCC, that is rate based and driven mixedly by sender and receiver, is presented. RBMCC uses the local loss rate and aggregated ACK of intermediate nodes worked out by receiver and TCP friendly rate computed by sender to provide a timely and accurate response to the network congestion. Simulation results show that RBMCC is scalable and TCP friendly. |
