摘要： Various exemplary embodiments relate to a method and related system and machine-readable medium including one or more of the following: receiving, at the MEP, a connectivity fault management (CFM) message; determining whether the CFM message includes an indication specifying a new value for a timeout factor; and when the CFM message includes an indication specifying a new value for the timeout factor, using the new value as the timeout factor. One or more of the following may also be included: when the CFM message does not include an indication specifying a new timeout factor, using a default value as the timeout factor; determining a timeout period using at least the timeout factor; determining whether the timeout period has elapsed since a most recent CFM message was received; and when the timeout period has elapsed since the last CFM message was received, determining that a timeout has occurred.
