摘要
This paper proposes a novel approach for introducing programmable functions into Internet-type networks. Specifically, the functions are designed to improve the quality of multiple video conferencing sessions when transmitted over DiffServ-enabled IP networks. The scheme operates through the use of the IPv6 hop-by-hop option header. Detailed simulations are presented that show how incorporating the programmable network functionality into the DiffServ routers guarantees the end-to-end delay for basic video playback is reduced by at least 50% with no packet loss.
