摘　　要：回顾了ＨＦＣ网络ＤＯＣＳＩＳ标准中采用的碰撞解决算法，通过计算机仿真比较了各种退避窗口设置的性能差异，在此基础上提出了基于负荷大小和ＦＩＦＯ首传规则的动态碰撞解决算法，并以仿真结果验证其性能，获得了较佳的性能参数。In this paper, contention resolution algorithm in DOCSIS standard for HFC networks is reviewed. The difference of performance for some backoff window settings is compared by computer simulation. We then present a dynamic algorithm based on the load and FIFO First Transmission Rule. Its feasibility is verified by computer simulation.
