QoS signalling across multiple domains is an open issue: in this paper we propose a QoS interdomain signalling solution for SIP-based multimedia sessions. Our solution refers to a signalling architecture proposed by ETSI in which the interdomain QoS signalling flows on the application layer along with the session signalling. In our solution we extend the precondition set attributes defined in the “Integration of Resource Management and Session Initiation Protocol (SIP)”, RFC 3312, to allow the domains along multimedia session paths to exchange information about the required resources and their availability in each domain.

Abstract
QoS signalling across multiple domains is an open issue: in this paper we propose a QoS interdomain signalling solution for SIP-based multimedia sessions. Our solution refers to a signalling architecture proposed by ETSI in which the interdomain QoS signalling flows on the application layer along with the session signalling. In our solution we extend the precondition set attributes defined in the “Integration of Resource Management and Session Initiation Protocol (SIP)”, RFC 3312, to allow the domains along multimedia session paths to exchange information about the required resources and their availability in each domain. Moreover in this paper we provide a signalling solution that integrates interdomain signalling and SIP end-to-end session negotiation signallingI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
