Research And Develepment On Service Accounting Of Next Generation Internet

With the pervasion of IP technology into various fields, telecom carrier network has gradually integrated into IP network, and the next generation of network NGN/NGI and the third Generation network are all using IP as the bearing network. Therefore, IP network will become the core network in the future, and it will gradually transites from a single data network to a multi service network.At the same time, with the rapid development of IP network, IPv4 protocol has exposed a lot of disadvantages, such as shortage of IP addresses, difficulty of providing QoS, etc. IPv6 is the next generation protocol which will replace IPv4, greatly improves the address space, QoS, security, mobility. Nowadays the IPv6 network is being widely deployed in our country, every network provider all focuses on the IPv6 development, considering the transition of their network platform from IPv4 to IPv6. Telecom service needs strict assurance of quality of service. Whether the current IPv4 QoS mechanisms can still be used in the new network environment and how to provide quality of service in the IPv6 network are the key issues which will impact the development of next generation network. How to solve the QoS problem in IPv6 environment, this right the key research contents of the CNGI QoS project.Presently, different QoS abilities are provided by main IP network equipment vendors, but they still can't solve the end-to-end quality of service.CNGI project "Research on CNGI QoS Mechanism, Key Network-constructing Technique and Correlative Implementing" focuses on how to provide QoS in the IPv6 environment. It aims at providing end-to-end QoS service for the applications by deploying a CNGI QoS management system over the physical networks. The New Internet Service Accounting Scheme is one of the important parts of the CNGI QoS system. Based on the new industry value chain and the developing trend of internet, and existing accounting schemes, a compound new accounting scheme is proposed. The new accounting scheme will become a good tool for all sorts of entities in the internet, such as Network Provider, Service Provider and Content Provider, to get success.Fistly the article introduce the background of the project briefly, then focus on the research status of the Internet Service Accounting scheme and the CNGI QoS management system. Based on the background and research status, the article proposes a new Internet Service Accounting scheme which combines closely with the trend of Internet development. Finally, introduce how the Accounting system is developed and its testing and verification progress.
