Provisioning in complex networks

Abstract

IP Multimedia Subsystem (IMS) solutions emphasize services including allInternet Protocol (IP) voice, data, video, multimedia, and other user-centric technologies-make possible such interactive multimedia services as multiparty video conference and user mobility (presence and location management) [15]. These services are the major contributors to data diversity in the network.Services operate on network and subscriber data in the network. Collectively, the network contains enormous amounts of service data. The structure (relational, hierarchical) and the kind (voice, video, text) of data depend on the service and technology, such as wireline or Voice over IP (VoIP). The diversity of data, services, technology, and vendors has caused the proliferation of provisioning systems, each catering to a technology domain [12] or a vendor [9] or a class of service [14]. These differences pose many challenges to unification. In literature,
