Abstract
An access node (e.g., DSLAM, OLT/ONT) is described herein that implements a trust verification method comprising the steps of: (a) filtering an up-stream message initiated by a non-trusted device (e.g., CPE); (b) intercepting the filtered up-stream message if the filtered up-stream message is a connectivity fault management message (e.g., LB message, LBR message, CC message); (c) inserting a trusted identification into the intercepted up-stream message; and (d) outputting the intercepted up-stream message with the inserted trusted identification. Thereafter, a trusted device (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 (e.g., IPTV network) can implement the trust verification method are also described herein.
