SCALABLE NETWORK PATH TRACING

Abstract:

A method implemented in a network device to enable scalable network path tracing. The method includes receiving a data packet with operations, administration and maintenance (OAM) information, updating a previous node identifier field in the OAM information, updating a current node identifier field in the OAM information, and sending a copy of the updated data packet with OAM information to a collector to build a packet trace.
