A method and apparatus to provide hop-by-hop tracking for a communication network is described. In one embodiment, each router verifies that a next downstream router supports tracking and in response, adds a tracking indicator and a timestamp to the data packet. An end router provides a compilation of all the timestamps back to the originating router.

Performance measurement in a network supporting multiprotocol label switching (MPLS)

A method and apparatus to provide hop-by-hop tracking for a communication network is described. In one embodiment, a router verifies that a next downstream router does not support tracking and in response terminates hop-by-hop tracking. An end router provides a compilation of all the timestamps back to the originating router.
