摘　　要：DOCSIS协议在HFC网络中的广泛应用,使其已成为事实上的标准。DOCSIS协议的目的是在HFC网络前端和用户端之间透明地双向传输IP业务,由于在HFC网络中存在大量的不确定因素,评估DOCSIS HFC网络性能一般采用仿真的方法。该文利用OPNET提供的CSF13仿真了DOCSIS HFC网络上行信道的吞吐量和平均接入延时。The DOCSIS specification is established as the primary HFC network data communication standard.The intended service will allow transparent bi-directional transfer of IP traffic between the HFC network head and customer locations. The way to evaluate the performance of DOCSIS HFC network is through simulation as there is considerable uncertainty in HFC network. In this paper, we utilize OPNET to simulate throughput and average access delay of DOCSIS HFC network upstream channel.
