摘要:

提出了一种用于实时多径传输的失序可控的负载分发模型.根据目的端反馈的各条路径的传输质量以及路径之间的失序信息,在源端动态更新各条路径上的负载分配份额,在满足与路径传输质量成正比的负载均衡的同时,最小化目的端的数据包失序风险.仿真结果表明,负载分发模型可有效降低目的端由数据包失序导致的丢包率.

Abstract:

A packet reordering-controlled load distribution model for real-time multipath transport was proposed. According to the feedback information of path transmission quality of all paths and packet out-of-ordering between paths from the destination, the source updated dynamically the load share of paths. Packet out-of-ordering risk was minimized while the load balancing proportional to the path transmission quality was satisfied. Simulations show that the proposed model can effectively reduce the total packet loss rate of the destination caused by packet out-of-ordering.

Key words: multipath transport, application-level relay, load distribution, packet reordering, real-time transmission
