Abstract:
1. A method comprising: receiving at least portions of media packets from a media stream, the media packets encapsulated in a tunnel having tunnel headers that include tunnel time stamps that identify approximate times when the media packets are initially trapped at an intermediary node, wherein the media packets include media packet headers including media time stamps that identify when the media packets were generated by a media source; receiving a first set of sequence numbers in the tunnel headers identifying an order that the media packets are trapped and receiving a second set of sequence numbers in the media packet headers identifying an order that the media packets are output from the media source; using the first set of sequence numbers to identify the media packets dropped over a first portion of a packet switched network using the second set of sequence numbers to identify the media packets dropped over a second portion of the packet switched network or while being trapped at the intermediary node; and analyzing the media stream according to where the media packets were dropped.
