COPS-Based Dynamic QoS Support for SIP Applications in DSL Networks

摘要

In this paper, several dynamic QoS solutions including Direct Diff-Serv, Admission-based Direct DiffServ, Indirect DiffServ, and Hybrid DiffServ are proposed to support largely emerging SIP-based P2P(Peer-to-Peer) and ASP(Application Service Provider) multimedia applications in DSL networks, most widely deployed as broadband access networks. The proposed solutions are designed to be based on standard COPS protocol which is simple and service-independent.
