| 摘 要： | 为了改善分层多播拥塞控制的性能,提出了一种基于适应性效用分层策略的主动分层多播拥塞控制方案DL-AALM.该方案采用了主动标记分层、适应性效用分层策略、逐跳反馈归并以及主动速率控制算法.仿真结果表明,DL-AALM方案具有较高的分层多播系统效用、较快的拥塞响应速度、较好的稳定性和TCP友好特性,大大改进了分层多播拥塞控制的性能.

| Abstract: | An adaptive utility layering policy-based congestion control scheme for active layered multicast, called DL-AALM (dynamic layering-adaptive active layered multicast), is proposed in order to improve the performance of layered multicast. Active label layering, adaptive utility layering policy, hop-by-hop feedback merging and active rate control algorithms are adopted in DL-AALM scheme. Simulation results show that DL-AALM is more responsive, more stable and TCP (transmission control protocol)-friendly, and can greatly improve the utility performance of layered multicast. |
