Abstract: The DOCSIS specification is established as the primary HFC network data communications standard. In order to improve HFC network to be full service network quality of service must be supported. Connection adimission control(CAC) must be considered. In this paper, the average delays of different traffic have been derived theoretically, and a method of CAC has been proposed.

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。为使未来的全数字化的ＨＦＣ网络成为全业务接入网，就必须支持服务质量。为了保证通信量的服务质量，任何实际的传输控制方案必须考虑对用户传输实施连接接纳控制，文章从理论上得出了高、低优先级通信量的平均延时，并提出了一种实时的接纳判决方法。
