ITU-T Next Generation Network Focus Group (NGN FG) Proceedings, Part 2

This document contains the advanced IP network architecture especially in views of end-user functions for control and management. The future IP network is not just focused into the provider provisioned single network. It equally considers the integrated environments of fixed/wireless network elements to accommodate computer systems, home peripherals and intelligent appliances. The future IP network may compromise of heterogeneous requirements of service quality and physical interface from network and computer and consumer equipments. A IP network guarantees real-time service quality and supports multimedia applications. It also provides bandwidth reservation and various service models for present and future business needs. The scope of this document covers: • Definition of and requirements for the service capabilities offered to an end user of a NGN, implemented with IP. • Reference architecture, from the end user perspective, of a manageable IP network • Functional capabilities, from the end user perspective, of a manageable IP network • Applications scenarios and procedures used by the end user of a manageable IP network Details of the mechanisms to support these capabilities are out of the scope.
