Abstract:
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.
