摘　　要：在基于前跳虚时钟(LFVC)算法的基础上进行了改进,将实时业务所预留的带宽和链路的剩余带宽实时地分离开来,并用剩余带宽改善非实时业务的平均时延和丢失特性,使得带宽资源的分配更加灵活。Based on the leap forward virtual clock algorithm , we proposed an enhanced scheduling algorithm to separate the reserved bandwidth andresidual bandwidth. The residual bandwidth can be used to improve the average delay and cell loss ratio performance of best effort services, which makes the bandwidth allocation more flexible.
