ETHERNET CONNECTIVITY FAULT MANAGEMENT WITH USER VERIFICATION OPTION

摘要

An access node (310) (e.g., DSLAM, OLT/ONT) is described herein that implements a trust verification method (350) comprising the steps of: (a) filtering (502) an up-stream message (370, 604, 702, 802) initiated by a non-trusted device (312, 312') (e.g., CPE); (b) intercepting (504) the filtered up-stream message if the filtered up-stream message is a connectivity fault management message (e.g., LB message (702), LBR message (604), CC message (802)); (c) inserting (506) a trusted identification (372) into the intercepted up-stream message; and (d) outputting (508) the intercepted up-stream message with the inserted trusted identification. Thereafter, a trusted device (304) (e.g., BRAS) receives and analyzes the outputted up-stream message with the inserted trusted identification message to ascertain a trustworthiness of the non-trusted device (e.g., CPE). Several different ways that an access network (300) (e.g., IPTV network) can implement the trust verification method are also described herein.
