Next Generation Networks have become reality, represented by two main candidate architectures, the 3GPP standardized IP Multimedia Subsystem and the ETSI/TISPAN standardized Next Generation Network which we commonly refer to as NGN in the following. With first NGN implementations being tested and early NGN solutions being already deployed, industry and research focus shifts from pure NGN functional aspects to integration, migration, quality of service and security aspects. However, even if NGN implementations currently exist, they do so as isolated islands, their sole common interoperability and integration path being restricted to legacy PSTN networks. This status questions the main paradigm of all NGN architectures to serve as an integration platform for circuit-switched and packet-switched, fixed and mobile networks. The FTW project BACCARDI (Beyond Architectural Convergence: Charging, SeCurity, Applications, Realization and Demonstration of IMS over fixed and wireless networks) aligns itself with the trend towards integration, being the first FTW project which adresses shared, as well as specific 3GPP IMS and ETSI NGN aspects. BACCARDI therefore will focus on a broad range of integration aspects which includes migration issues, identity management, and overload situation handling from an architectural point of view. Factors which BACCARDI considers to be decisive for NGN acceptance include the definition of novel integrated services and enablers, as well as analysis and provisioning of appropriate security mechanisms as countermeasures to NGN attacks with dedicated focus on Spam over Internet Telephony (SPIT), which is commonly agreed on to be a high risk for NGN success. With increasing number of customers migrating to NGN, service differentiation by means of quality of service will be of paramount importance for positive user experience, same like flexible charging offerings. Finally, integration aspects govern also the planned BACCARDI testbed evolution towards interoperability and interconnect. A cornerstone of testbed extension will be the integration of existing third-party components for MGCF, MGW and SBC, complemented by feasibility studies and optional development of prototypes for components like RACS and NASS.
