ABSTRACT:
Fault isolation in a network includes embedding in-band traceroute packets in a media stream, passing the traceroute packets into a network connecting a proximal end point and a distal end point, monitoring the network for responses, expected from respective traceroute packets, from each of a plurality of network devices that are disposed between the proximal and distal end points; analyzing the respective responses; and based on the analyzing step, identifying one or more of the network devices as being responsible for a fault. In a preferred embodiment, fault isolation further includes correlating un-acknowledged, i.e., un-responded, traceroute packets with packet loss and or jitter computed at the distal end point.
