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.
