Abstract

Power outages can seriously disrupt the digital services over community antenna television (CATV) networks. This paper proposes two novel schemes for the ranging process of the Data Over Cable Service Interface Specification (DOCSIS) protocol, within the dynamic persistent ranging framework, which offer an absolute reduction of up to 34% in a cable network's recovery time with an average of 28%. Based on the number of previously, active cable modems (CM) the CMTS allocates the best backoff start/end and updates them once (single backoff shift, SBS) or continuously (continuous backoff shift, CBS) as soon as a percentage of a non-ranged CMs is reached.

DOCSIS网络快速动态恢复测距方案
电力中断会严重干扰社区天线电视(CATV)网络的数字服务。本文提出了两种基于动态持久测距框架的电缆数据服务接口规范(DOCSIS)协议测距过程的新方案,这两种方案可使电缆网络的恢复时间绝对减少34%,平均减少28%。根据先前的有源电缆调制解调器(CM)的数量,CMTS分配最佳后退开始/结束,并在达到非远程CMs的百分比时立即更新它们一次(单后退移位,SBS)或连续(连续后退移位,CBS)。
