Patent US7966409 - Routing protocol based redundancy design for shared-access networks - Google Patents
A protection CMTS is available to immediately service a cable modem should that modem's service from a working CMTS fail for any reason. To speed the service transfer (cutover) from the working CMTS to the protection CMTS, the cable modem may preregister with the protection CMTS well before the cutover...http://www.google.co.uk/patents/US7966409?utm_source=gb-gplus-sharePatent US7966409 - Routing protocol based redundancy design for shared-access networks
