Abstract

A communication system includes multiple routers interconnected by a packet-based communication network. Each of the routers includes a monitoring application that monitors quality of one or more packet flows during each of multiple successive monitoring periods. For each of the packet flows, the monitoring application determines quality metrics based on information obtained from transport headers of packets.
