Abstract
In networks that support service differentiation, each in their own way, it is very important to manage how interactive multimedia applications use the networks’ enhanced services. Therefore, ways to ensure that these services are properly authorized and accounted for are needed. This paper addresses the role of Session Initiation Protocol (SIP) proxies to authorize QoS-enabled multimedia sessions, based on the session’s policy information and the network resources’ availability. Our inter-domain call authorization model provides call authorization status and adds more granularity to the authorization process. This model is implemented in a SIP testbed, and simulation results showed that the model is scalable at end domains.
