SIP services and interworking with IPv6

This paper presents a research project that has implemented a Mobile IPv6 enhanced native IPv6 network on which different TCP and UDP based protocols are used. The most important protocol is considered to be the Session Initiation Protocol, which defines the infrastructure and end client behavior for efficient end-to-end session setup. An overview of the project targets is first given and each technology used is described. Topics covered are IPv6 and Mobile IPvB, transition mechanisms and the Session Initiation Protocol (SIP). The project achievements and possible future work is also presented. A conclusion of the technologies used in the research project is given.
