19 IP The Unifier: Hides The Network Infrastructure From The Applications WWW VoIP Mobile Commerce... Anything over IP IP facilitates usage of applications across network boundaries (write once - use many times) Internet PSTN Switch PLMN Unified provisioning of IP applications Corporate Network IP over Anything A common IP layer harmonises networks and provides internetworking over different network technologies 19

20 IP The Unifier Opens the Door to a Unified IP Infrastructure WWW VoIP... Mobile Commerce... Common IP+ infrastructure Interworking with non-ip networks via media gateways or mediation devices Reduction of complexity and cost due to unified IP infrastructure 20

21 Characteristics Of The IoA Network " End-to-end IP, internet compliant (IETF, W3C, DMTF) " Enhancements where necessary to enable mobility. Design is based on ipv6 " Support end-to-end multi-media communication over heterogeneous networks " Use TCP/IP as a common framework for multimedia communication " Enable global mobility " Access over many different networks (wireless & wire line) " Interworking with existing (legacy) networks " Provisions for allocation and management of network resources " Voice is only one possible application, although an important benchmark Clear split between transport network and applications 21
