摘　　要：基于前跳虚时钟算法原理提出了一种新的调度算法 ,它将业务所预留的带宽和链路的剩余带宽实时分离 ,并用剩余带宽改善其他种类业务的 Qo S特性 ,使得带宽资源的分配更加灵活 .理论分析和仿真证明 ,算法不仅降低了“尽力而为”业务的平均时延 ,还具有确定的时延保证和公平性 .Based on the leap forward virtual clock algorithm, this paper proposed a new scheduling algorithm which can separate the reserved bandwidth and residual bandwidth. The residual bandwidth can be used to improve the QoS performance of best effort services, which makes the bandwidth allocation more flexible. The deterministic delay guarantee and fairness performance were also demonstrated and proved by the simulations.
