Abstract
A multicast tracing system for a network is provided. During operation, the system can identify, at a network device in the network, a join request and a data packet of a multicast group received at the network device. The system can determine respective timestamps indicating the arrival and departure of the join request and the data packet. The system can then determine, based on the timestamps, at least a local latency incurred by the data packet at the network device and a network latency incurred by the data packet in the network. Subsequently, the system can receive a multicast trace (mtrace) request for the multicast group. The system can incorporate the local latency and the network latency into the mtrace request. Upon identifying an upstream network device in a multicast path associated with the multicast group, the system can forward the mtrace request to the upstream network device.
