Managing P2P services via the IMS
Antonio Liotta, Lin Ling · 2007
The key aim of our work was to illustrate the benefits and means to deploy P2P services via the IMS. Having demonstrated the technical viability of P2P-IMS we have also found a way to add a new management dimension to existing P2P systems. P2P-IMS comes with a natural "data management" mechanism, addressing the DRM problem which is still a major hurdle in existing P2P platforms. In P2P-IMS, the IMS manages user registration, authentication, and authorisation, as well as monitoring, charging and billing. The immediate benefit is that P2P-IMS can be used as a building block to deploy managed secure group communication services. By contrast to existing P2P systems, in P2P-IMS group members are authenticated securely. In this way it is possible to manage authorisation policies in P2P communication and data exchange.
