Research On Differentiated Service Mechanism Based On IPv6 Customer-Service Address

With the rapid development of computer network skill,there are more network applications and more requires for the carrying capability of the network.Though IPv4 played an important role in the development of Internet and made a great success,for the limitation of address resources,uncertainty of address allocation,deficiencies of protocol design and etc,gradually it restricted the development of Internet.Moreover,IPv6 grows mature and is going to become the carrying protocol for the Next Generation Internet(NGI).The telecom operators are also hoping that,when the NGI is widely brought into effect in commerce,they could make a scientific and reasonable overall plan for the IPv6 address allocation.Therefore,the network carrying capability and the enterprises capability of completing,both could be strengthened.Currently,the ways of address allocation that are often used are limited within the method of Sequence-Scheme and Bisection-Scheme.These methods are simple,but they could increase the fragment of vacancy address and the load of Internet management.Furthermore,while the IPv6 addresses were allocated without considering the types of the customers and service model,which will increase the difficulties of traffic flow identification in NGI.Based on the existing research results,the paper made a deeply research on IPv6 address format and the new concept of IPv6 customer-service address on construction new aspect,and built up a networking model based on IPv6 customer-service address.On the basis of IPv6 customer-service model,E-Number differentiation service system was designed and implementation.Then the system was tested in test environment.The test result shows that the system achieves the designing goals well.At the end of this paper,this article discussed the project of networking model based on IPv6 customer-service address in QoS,customer exploration,the management and control of P2P traffic flow and etc.
