摘　　要：针对多节点综合业务传输链路,提出一种基于起始时延调整的分布式时延抖动控制方案,并通过仿真对比的方法对该方案的有效性进行研究。结果表明,该方案可大幅度减少多节点链路端到端的时延抖动以及网络缓冲空间需求总量,并可使链路节点的缓冲空间分布趋于均衡且具有一致性。A distributed jitter control scheme based on the initial delay regulating is presented for the integrated service transmission via a multi-node link. The validity of the scheme is studied by means of simulation. The results show that the scheme is capable of providing a significant reduction in end-to- end delay jitter of the link, and requires smaller amount of buffer space to be allocated. Also the scheme makes the space much more uniformly distributed along channel routes.
