Research And Implementation Of Key Technologies Of Identifier Network Based On IPv6 Protocol

With the rapid development and coverage of IP network in recent years,as well as the diversity of terminal devices and the popularity of wireless access,making the mobility of network has become an important demand.However,based on the traditional TCP/IP protocol system,IP address has dual attributes of identity and location identification.The ambiguity of IP address brings great trouble to the implementation of mobile network.The key to solve this problems in the duality of IP address.The Identity and Location Separation Protocol can solve the semantic overload of IP address fundamentally,which makes it having unique superiority in the implementation of mobile network.At the same time,the gradual expansion of the Internet scale has led to many problems,such as the lack of IPv4 address,the mobility of network,the expansion of routing tables.As the core protocol of the next generation network,IPv6 protocol can solve the limitations of Ipv4 network fundamentally.According to the development of IPv6 networks and the mobility management deficiencies withing traditional networks,this thesis combines the separation technology of identity and location technology and IPv6 networks,and studies the key technologies as follows:1.This thesis firstly studies identity and location separation protocols including HIP,Shim6,and LISP.The main characteristics and signaling processes are analyzed.2.The characteristics and problems of IPv6 mobility management schemes based on the current TCP/IP architecture are studied,mainly focuses on MIPv6 protocol and its extension and optimization techniques.At the same time,the mobility management schemes based on identity and location separation protocol are studied.Based on the design idea and the advantages and disadvantages of the schemes,a new IPv6 based network architecture of identification bearer network is proposed.3.Mobility management scheme based on identity mapping and hierarchical registration update.4.For the security requirements of the network,the IPSec is introduced into this network architecture,which provides protection to the data via a security tunnel.5.The main functional entities in the network are developed.And the experimental platform is built to test the key technologies in the project.
