Abstract: In real-time multimedia, the overall time in Internet communications must be low and constant, in order to keep real-time sense and received media quality. When mobility is a basic requirement, efficient and flexible solutions should be adopted, avoiding harming time sensitive applications. In order to support mobile real-time multimedia communications on Internet backbones, a novel SIP extension is proposed, adding direct support to handover procedures in SIP clients. The procedures of that new extension, MobSIP, are specified and implemented in SIP clients, allowing formal and experimental verifications.
Keywords: SIP, Application layer mobility, Handover procedures, Real-time multimedia, fFormal specification.
