14、 Status At its 9thmeeting in London, 14-17 November 2005, the Focus Group on NGN has provided a view on the status of the documents. Deliverables that are marked “P“ in the sixth column of tables 1, 2 or 3, have already been passed to ITU-T Study Group 13, and one has been published, as shown. The F

15、GNGN considers that the deliverables that have given the status “A“ have been developed to a sufficiently mature state, as technical reports, to be considered by ITU-T Study Group 13 for publication. The FGNGN considers that those deliverables that have gained the status of “S“ have reached a mature

16、 state but would require further consideration in Study Group 13 before publication. The FGNGN considers that all other deliverables shown as status “D“, are not yet mature, requiring discussion and technical input to complete their development. 2 NGN Focus Group deliverables ITU-T FGNGN deliverable

44、.1 Framework for Customer Manageable IP network Introduction 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

45、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.

46、 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. A IP network has the following general features. Support business model for differentiated service concept

47、 Support usage-based billing and charging model Stable and secure with reliability performance of 99.999 % To support these features, the network operator provides network connectivity services to its end users. A service level agreement (SLA) is a formal definition of the contractual relationship b

48、etween service provider and its end user 14. It specifies what the end user wants and what the supplier commits to provide. It defines the level for the quality of services provided, setting performance objectives that the supplier must achieve. It also defines the procedure and the reports that mus

49、t be provided to track and ensure compliance with the SLA. In this service environment defined by a SLA, the IP network should be reliable and manageable. The end-to-end connectivity should meet the negotiated SLAs according to various application types and equipment types. The users may want to include their specific performance requirements in terms of bandwidth, delivery time, and loss performance for each application. But, some users may not want SLA like the existing Best Effort
