Abstract
The present invention provides a system and method for improving the quality of real-time multimedia sessions wherein each endpoint of a real-time packet stream transmits (1) feedback reports that describe the quality of the stream received by the endpoint and (2) forward reports that are based on the feedback reports received by the endpoint and that describe the quality of the stream received by the other, remote endpoint. The forward reports are used by routers to re-route packets around problems in the network that are located between the router and the remote endpoint.
