Research And Implementation On IPv6Support Online Proxy Technology

Nowadays it is in the IPv6transition phase. It is a long process from IPv4toIPv6, IPv6transition technology is the an important tool and to solve IPv4and IPv6interworking. This paper studies the realization of the principle IPv6transitiontechnology, features, advantages and disadvantages, analyzes their problems, studiesthe proxy server how to work and the role of technology for the analysis of theproblems of the transition into the necessity of a proxy server, presents a speciesintroduced proxy server methods to solve the client access IPv4Environment IPv6environment Web servers.First of all, this paper based on the previous theoretical analysis and research,designs and and realized an IPv6online proxy system, the system’s main function isto IPv4environment, clients can access the website and enter the proxy server toaccess the IPv6environment to a Web server URL for a visit. And the system carriedout a detailed needs analysis and module structure is divided, this system is dividedinto the background module, agent module, the interface module and cache modules,and each module used in the concrete implementation and related technologies aredescribed.Secondly, this paper detailed analysis of the Web Cache difference with thetraditional cache, analyzes cache replacement algorithm works and processesproposed URL hit rate, byte hit rate and access latency rate three evaluation index.Specific research and analysis advantages and disadvantages of the four kinds of theclassical algorithm, simulated experiments and comparative analysis, in which thebased on value of Hybrid algorithm retention compared to the other three algorithmsURL hit rate is relatively high, the access delay rate is relatively low, but byte hit rateis not very high. To solve this problem on Hybrid optimization algorithm twice, andagain carried out simulation experiments and comparative analysis, the secondoptimized Hybrid algorithm byte hit rate has significantly improved.Finally, this paper finally performance test the IPv6online proxy system,simulates5000client runs60seconds to send a request to the proxy server, thesuccess rate was94.98%. Test results shows that the system can be a high number ofconcurrent connections, the memory consumption is less than2G, with goodperformance.
