Design And Research Of Distributed Network Based On XMPP Protocol

With the rapid development of information and network communication technology,enterprise information construction process is accelerating,the structure of enterprise information network and the security management of information resources become more important.Distributed control network uses decentralized control,each node can directly establish the data link,which is convenient for the whole network to share the resources,even if the entire network of a partial failure,it will not affect the operation of the whole network,with high reliability.It can meet the needs of the construction of the current enterprise information network.XMPP protocol is an open,flexible and extendable protocol,which is based on XML the real-time message and online protocol.It has a unique advantage in the distributed network expansionAt first,this paper introduces the relevant knowledge of XMPP protocol,the communication principle of XMPP protocol,and the communication between XMPP servers,and the communication between the server and client.Then the paper based on the XMPP protocol and the mature MINA framework to achieve the function of network server,including receiving,processing,backing-up and forwarding the authentication information of park server as well as the design of corresponding database.At the same time,it focuses on the key technologies of distributed network server,such as the response of the server to the network,the server to monitor the network status,the choice of the core server and the synchronization and backup of the data between the servers.In the end,the distributed network is deployed and online tested and achieve satisfactory results.
