Abstract

Voice, video and multimedia sessions are applications sensitive to the QoS provided by the underlying IP network. Therefore a lot of interest is currently devoted to the interaction of application level protocols with the QoS mechanism in IP networks. Among them SIP is currently having a lot of attention as a protocol for session signaling over the Internet. This work will describe an enhancement to SIP protocol for the interworking with a QoS enabled IP network. The proposed mechanism is simple and it fully preserves backward compatibility and interoperability with current SIP applications. Moreover the paper describes the application of this mechanism to a particular QoS enabled IP network, which implements DiffServ as transport mechanisms (the DiffServ mechanisms are obtained by means of Traffic Control functionalities with the TCAPI software libraries) and modified COPS clients for resource admission control. A test-bed implementation on Linux PCs of the proposed solutions is finally described.
