Abstract:
WRR and DWRR in the architecture of DiffSever was discussed. And based on WRR, an adaptive weighted round-robin (AWRR) and how to carry out this algorithm was presented. By this algorithm, different packets have different weight, and schedule packets according to this. So that AWRR not only can obtain the requirement of QoS, but also can according to the node’s condition dynamically assigning the bandwidth and the bandwidth resource sharing.
Key words: P DiffServ, quality of service, weighted round robin, adaptive weighted round robin
摘要:
分析了在DiffServ模型下的WRR和DWRR调度算法,提出了一种基于WRR的改进的 调度算法AWRR(ADWRR),同时提出了AWRR调度算法的实现过程。该算法根据网络中各业务数 据的实际流量动态的调整其对应的权值。因此AWRR不仅能提供QoS保证,而且还能根据该节点的 实际负载状况,提供动态的带宽分配。
