摘要 本文提出一种新的语音流队列管理调度机制 ,结合随机早期探测 (RED)和主动丢包调度算法实现因特网语音流的队列管理和调度 .采用仿真方法分析了新机制的性能特征 ,并与RED做了性能对比 .当网络拥塞时 ,该算法可有效改善包转发的性能 .语音质量测试表明新机制是可行的和有效的 . This paper proposes a new queuing management and scheduling mechanism for VoIP queues,which coordinate RED and a scheduling algorithm of advisedly dropping packets.Simulation results show that the mechanism enables some improvement of the performance of packet forwarding effectively during network congestions compared to RED and FIFO scheduling.VoIP quality measurements verify its feasibility and effectiveness.
