High Availability (HA) has not been standardized as part of the CCAP and MCMTS specification efforts and therefore implementation of these capabilities has been interpreted differently by each system implementer. This paper presents scenarios for applying High Availability (HA) systems concepts to the new DOCSIS Remote PHY architecture.
An overview of DOCSIS Remote PHY is
presented to introduce the new architecture. Next, to set the context for high availability systems, models and tactics for generalized HA systems are presented. The document concludes by combining the concepts of Remote PHY and HA to suggest models and scenarios for creating High Availability (HA) systems supporting DOCSIS Remote PHY architectures.
