Abstract
From both technical and economic viewpoints, DiffServ IP QoS architecture is accepted as a more practical solution in Internet world because the other IntServ architecture is more complex and has scalability problem. This paper presents a dynamic DiffServ Model called Indirect DiffServ to support dynamic QoS requirements of SIP-based ASP multimedia applications in broadband access networks. An operational model of QoS-enabled broadband access networks to support dynamic QoS for SIP is firstly proposed. Then the procedures to establish QoS-enabled SIP sessions of ASP applications are presented. The signaling interfaces for dynamic provisioning of DiffServ QoS are designed to be based on COPS and COPS-PR protocols. The inter-layer mapping of QoS attributes between SIP and underlying layers is also discussed in this paper. The underling broadband access networks are assumed to support largely-deployed Metro Ethernet 802.1 D/Q QoS.
