本文提出了基于丢失优先权公平队列 (FQLP)调度算法 .理论分析和仿真实验表明FQLP调度算法能保证实时业务获得的网络资源不小于预约带宽 ,为实时业务提供确定的时延上界 .FQLP调度算法利用ATM网络中的信元优先权机制 ,提高了网络资源的利用率 .同时FQLP调度策略能保证信元的发送顺序 .
In this paper, FQLP scheduling algorithm is proposed.The theoretical analysis and simulation results show that the FQLP scheduling algorithm can ensure that the network resources obtained by real-time services are not less than the reserved bandwidth and provide a definite upper bound for the real-time traffic.FQLP scheduling The algorithm makes use of the cell priority mechanism in ATM network to improve the utilization of network resources.At the same time FQLP scheduling strategy can guarantee the order of cell transmission.
