【摘要】 针对现有区分服务网络中多服务间带宽公平性问题,提出了一种自适应加权调度方案。该方案通过对本地节点缓存区指标的定期测量,计算得到在各队列间公平分配剩余带宽的调度权值。仿真结果表明,该方案可以在网络负载变化时自适应的快速调整到理想调度值,有效改进了带宽分配的公平性。更多还原

【Abstract】 An adaptive weighted scheduling scheme is proposed for the fairness problem among multiple services in current differentiated services network. This scheme periodically measures the metrics in local buffer of router, and calculates the scheduling weights for fair bandwidth allocation among the queues. Simulation results show that it can quickly and adaptively adjust the scheduling weights to ideal settings upon the changes of traffic load, which effectively improves the fairness of bandwidth allocation.更多还原
