Abstract:
1. A cable modem termination system comprising: machine memory and/or circuits comprising logic to maintain an operational status indicating whether each of a plurality of fiber nodes coupled to the cable modem termination system is operationally capable of providing service to cable modems over each of a plurality of MAC domains, wherein each MAC domain communicates with a plurality of fiber nodes over a plurality of downstream channels and a plurality of upstream channels, at least one downstream channel from each MAC domain coupled to carry data from the MAC domain to a first plurality of the fiber nodes, at least one upstream channel to each MAC domain coupled to carry data from a second plurality of the fiber nodes to the MAC domain, the CMTS maintaining the operational status separately for each unique pair of MAC domain and fiber node, the operational status including which downstream channels and which upstream channels are active and properly functioning between each unique pair of MAC domain and fiber node, which downstream channels and which upstream channels have a respective fault, and a respective state of each fiber node; and machine memory and/or circuits comprising logic to formulate a minimum requirement for identifying each unique pair of MAC domain and fiber node as operationally capable of providing service to the cable modems, and logic to generate, from a DOCSIS MIB, a suitability metric for a particular cable modem architecture to a particular fiber node, the minimum requirement comprising:
