7. Introductory Papers [1] Mohamed El-Sayed, Jeffrey Jaffe, A View of Telecommunications Network Evolution, IEEE, Comms Magazine, December 2002 [2] M H Reeve, C Bilton, P E Holmes, M Bross, Networks And Systems For BT In The 21st Century, IEE Communication Engineer, October/ November 2005 BT = British Telecom (known as 21CN) © Peter Komisarczuk, VUW, 2003-9

8. Rationale for 21CN? • Replace many “stove-pipe” single service networks with a single “converged” network • Remove multiple OSS (operational support systems) – large $ savings • (Management, billing, customer care, etc.) • Avoids “interworking” issues - large $ savings • Create new opportunities (services) and faster service enablement (provisioning • Intelligence layer and application platforms © Peter Komisarczuk, VUW, 2003-9

11. Network Provider Architecture • Access Network – “first mile” or “last mile” • Aggregation Network • (Metropolitan Network) • Metro Office Node (IP Services Node or sometimes called aggregation router) • Backhaul Network • Regional Network • Backbone (or core) Network • Inter-network transit points © Peter Komisarczuk, VUW, 2003-9

12. 21CN Service Execution Network © Peter Komisarczuk, VUW, 2003-9 Figures from [2]

13. Service Extensions • Legacy service encapsulation • Mobility Services (session, user, and terminal mobility) • Multimedia Services (voice, video, data) • Hosting Services (e.g. VoD) • ICT Services (outsourcing of infrastructure hardware (terminal and hosting) and software [application] service providers) • Connectivity Services (IP VPN, Ethernet services, optical services, etc.) • Third Party Services (open interfaces, APIs) © Peter Komisarczuk, VUW, 2003-9

14. Main Principles • All services over IP • Edge adaptation, IP, MPLS, optical core • Multi-Service Access Node (edge) • Metro Node (IP Service Node or BRAS) • Quality of Service (QOS) support • Mobile and fixed network integration • Middleware • 3GPP (3rd generation partnership project) IMS (IP Multimedia Subsystem) • Reusable service components (SOA) • One touch support systems (OSS) • Workflow engine, component orchestration © Peter Komisarczuk, VUW, 2003-9
