摘　　要：文章以EDF算法为基础,提出一种改进的调度算法IEDF。在IEDF中,提出一种新的带宽调度策略,并在3种具体情况下进行业务流调度过程分析。同时,在SIM环境下进行仿真实验,仿真结果表明,和原EDF算法相比,IEDF算法有效保证了带宽,降低了时延,提升了Qos。An improved earliest deadline first （EDF） scheduling algorithm （IEDF） was proposed, which involves a new scheduling strategy to properly dispatch bandwidth when a variety of network business coexist. The scheduling process of network business bandwidths dispatching in three cases was analysed. Meanwhile, simulation experiments were conducted in SIM environment. The simula- tion results show that the IEDF algorithm ensures the bandwidth dispatching more effectively, lowers time delay and improves the Qos compared with the original EDF.
