Based On Group Communication Protocol, Applied Research And Realization

As the rapid development of Internet, many new communication methods have come forth, the traditional point-to-point Unicast protocol can't meet the requirements now. So people proposed group communication protocols, such as Multicast and Anycast, to decrease the server's burden and increase users' access speed. This paper major researches the applications and implementation of group communication protocol.By analyzing and comparing existed Multicast anonymous communication protocols, contraposing to the weakness and shortcoming, this paper proposes a new Multicast anonymous communication protocol MACP, MACP uses camouflage group mechanism and multi-agent forward technology to achieve anonymity of receivers and senders, add a little network payloads to hide the both sides' communication relationship and increase the security and anonymity of communication process.By analyzing the Anycast protocol's RFC documents and existed Anycast protocol implementation specifications, this paper proposes a brand-new Anycast protocol implementation method, this paper details the method that supports Anycast protocol on Linux IPv6 soft router, discusses the designation and implementation of kernel Anycast protocol, Anycast information exchange protocol, Anycast group management, some difficulty and key technology. And according to this method I have finished programming task on Linux platform in IPv6 environment, which is the basement of Anycast protocol's application and further research jobs.
