Executive Summary

In this paper, the authors study a mechanism which allows the sender application to mark video packets based on its importance in reconstructing the video. Passing such video frames to Differentiated Service (DiffServ) network increases the video quality and treats the video frames based on their priorities. A media aware sub-layer has been added to the edge routers in DiffServ network. The media aware sub-layer has the responsibility to cache high priority video frames. They demonstrate through simulation that the proposed mechanism decreases the average packet delay, and the packet loss. This in turn produces a better video quality at the clients than produced under the existing techniques.
