White Paper Abstract:
This white paper describes the requirements for IP networks to support an IP Next-Generation Network (NGN) environment. Carrier-class IP will become a fundamental requirement in the development of IP NGN and associated services. Illustrating how this development might occur for a typical traditional service, a scenario is presented in which carrier-class telephony is migrated from traditional circuit switching to IP. Each aspect of carrier-class IP in this migration is discussed to provide for a complete overview.
