摘要
区分服务是提供QoS的重要机制之一,但在区分服务中存在着汇聚流之间剩余带宽分配的不公平性问题。为解决该问题,提出了动态数据包标记算法(DPMA),该算法通过监测汇聚流的流速变化,能动态地调整标记策略,它能以一种近似按比例的方式在各汇聚流之间公平地分配网络中的剩余带宽。仿真结果表明该算法是有效的。
Diffserv is an important mechanism to provide QoS,but there are unfairness problem in sharing the excess bandwidth between aggregates.To solve the problem,this paper proposes an algorithm named DPMA which changes the marking policies dynamically according to the change of the aggregates＇s speed.The algorithm achieves proportional fair sharing of excess bandwidth among aggregates.Simulation result shows that the algorithm is effective.
