The Design Of The Unified Management About The Address Pool Based On Public Address Resource Allocation Of NAT

With the rapid development of information technology,the network application is rich and varied,and the network scale is expanding continuously.Serious shortage of IPv4 address resources in the world.The introduction of IPv6 is the inevitable trend of the evolution of the network.In the initial stage of evolution,Operators of the network,business platform,terminal and other technologies can not fully support the IPv6,and has the ability to IPv6 commercial.Therefore,in the future for a long period of time,IPv6 can not completely replace the IPv4,both of which will exist in the way of coexistence.In this paper,we first introduce the three IPv6 transition technology,focusing on the Ipv6 to the IPv4 protocol conversion technology,Analysis of the translation technology used in sparsely populated where the device has a wide distribution and the low utilization rate of address,the management of the network address resource allocation of NAT will be useless.An improved method of address resource management is proposed,The method can optimize the management and deployment of address resources,save the address space,and make the maintenance of routing information more efficient.In this paper,the unified management of static global address pool and the unified management of dynamic global address pool are designed for the purpose of unified management of address resources.Articles starting with the static method,Analysis of the interaction between each module of CGN device,a detailed study of the static global address pool creation,the address resources add,the initial segment,increment,upper and lower threshold configuration and the address resources application and release.Then,the limitations of the static method are analyzed,and the dynamic method is proposed,In dynamic method,on the basis of the constant interaction process between each module which is located on the CGN device of the static method,the interaction of the Radius server and the AAA module are also introduced.The interactive implementation process is described in detail,and the design of dynamic method is completed,In this paper,At the end of the implementation of the static methods and dynamic methods,both have carried out a detailed test of the relevant functions,the results are in full compliance with the expected results.
