摘要
为了适应覆盖网络节点之间虚拟链路带宽资源的动态变化,在流媒体数据采用单层的自适应编码方式下,提出基于速率的应用层多播逐跳拥塞控制方案。该方案在跳内采用成熟的端到端拥塞控制机制,在跳间采用上下游速率的自适应调整。测试结果表明,基于速率的应用层多播逐跳拥塞控制方案可行有效。
In order to be adaptive to the dynamic change of the overlay link＇s bandwidth, proposes a new layer based application level muhicast hop by hop congestion control-RHBHCC, which is streaming oriented and the multimedia data is single layer adaptive coded in it. RHBHCC applys the mature end-to-end congestion control mechanism within one hop, and applys adaptive adjustment between upstream and downstream hops. It is proved by test that the rate based application layer muhicast hop by hop congestion control schema is feasible.
