| 摘 要： | 提出了一种新的基于数据包束探测(packet-bunch probe)和TCP吞吐量公式的多速率多播拥塞控制方案PTMCC(packet-bunch probe and TCP-formula based multicast congestion control)。这种接收端驱动的拥塞控制,采用数据包束来探测网络的可用带宽,利用TCP吞吐量公式得到TCP友好速率,并采用了新的速率调节算法。仿真实验表明,PTMCC在收敛性、灵敏性以及TCP友好性上具有较好的性能。

| Abstract: | A novel congestion control mechanism based on packet-bunch probe and TCP throughput formula(PTMCC) was proposed.This receiver-driven multi-rate multicast congestion control mechanism probes available bandwidth by packet-bunch and gets TCP-friendly rate by TCP throughput formula.A new rate adjustment algorithm was also designed.Simulation results show that the PTMCC make good performance on convergence,TCP-friendliness and response to congestion. |
