Abstract
In certain embodiments, monitoring a flow set to detect faults includes identifying, by a first maintenance end point, a flow set comprising flows that utilize a paths from the first maintenance end point through one or more intermediate nodes to a second maintenance end point. Continuity check messages are generated. Each continuity check message is formatted as a data packet that an intermediate node forwards. Each continuity check message comprises a header comprising a maintenance indicator. The continuity check messages are transmitted on the flows to allow the second maintenance end point to monitor the paths.
