Managing Multimedia Traffic in IP Integrated over Differentiated Services: SIP dynamic signaling inter-working
The current IETF standardization work has highlighted the feasibility of providing the users with a QoS network architecture in the framework of Integrated Services over Differentiated Services. In such a framework other works have highlighted the need of a coordination between the access signaling protocols and the transport level resource reservation mechanisms. In this work we propose a general method and coordination of these transport level mechanisms between SIP entities and the QoS DiffServ architecture supposed to act as the interconnecting network. A re-defined version of COPS developed in our laboratories is used for authorization/resource allocation requesting; such protocol re-definition is optimized for managing the multimedia flows when requesting access to the DiffServ architecture so making able a SIP server to commit resources for the calls that it is managing. The procedures needed to establish the QoS call over a multidomain DiffServ scenario will be discussed; the ...
