Design And Implement Of Gateway Auto Configuration And Traffic Detecting In Universal Identifier Network

With the rapid development of Internet technology,with the constant expansion of the network scale,the routing scalability problem,the security problem and the mobility problem become more and more serious.With the technical of separating the identifier and location to separate the dual attribution of the IP address,the Universal Identifier Network has become the main research direction of the next generation Internet.When IPSec has been deployed in large scale,the confidentiality and integrity of communication in the Universal Identifier Network.Meanwhile,in order to solve the difficulty in the gateway configuration to deploy the IPSec scalely,a kind of IPSec gateway auto configuration technology must be proposed.As the research shows,high load,bad flexibility and single point failure etc.,these problems are met in the current technology of gateway auto configuration.Also,the constant feature of AID helps locate the location of the terminal user and track the mobile path of its packet.In perspect of the flow distribution and monitoring the entropy,we dig up the deep distribution features of the flow.In order to solve the above problems,this thesis designs and implements a auto IPSec configuration technology and flow detecting technology,and provides better adaptability.The main work is as following:At first,we deploy the IPSec auto configuration technology by directly deployed on IPSec gateway and intrigger the interaction of IPSec gateways,and increase the interaction reliability by the timout retransmission mechanism,and protect the access network by implementing multiple strategy configuration,and increase the system flexibility to support IPv4 and IPv6.In order to detect flow,we propose a plan of distribution collection and centralization dealization.According to research,we describe the Universal Identifier Network and the IPSec protocol as well as its necessity,and disscuss the deployment plan.We introducee the inception of network info traffic detection and the infomation entropy.Base on these theory,we analyze the demand of the IPSec gateway auto configuration and the traffic detection technology,and disscuss the system designing.We design the intrigger subssytem,the interaction subsystem,the console subsystem and the engine subsystem.We design and implement the functionmodules of the system by module designing,and finally complete the implemention of IPSec auto configuration and network traffic detection.In the end,through testing and analysis,the functions of the system is verified and we discuss the research and improvement of the system in the future.
