Research And Design Of The Answering System On Network Based On P2P

Along with the computer technical universality, more and more people carry on a study through a network, having already become a kind of new education mode to develop quickly according to the education of network. Answering is an important tache of the net education, it offers an important platform for tutorship, communication and teaching's feedback. Now answering system mostly are C/S or B/S mode, the net work applies the concentration to a little amount server up, a great deal of customer carries an equipments mutually of can't communicate mutually, can make contact with server, resulting in a great deal of waste of resources, and C/S system since need customer to carry software and need the server soft hardware, cause thus excessive of saving equipments and software, also bring more maintenance works.The paper makes an analysis of the existing few kinds the answering system , combines the characteristics that the traditional classroom answers ,gives the design project of answering system based on P2P, the JXTA platform provides the foundation service of the P2P procedure, the system developing in the P2P network, the system chooses pure P2P mode to avoid the problem of traditional C/S mode, It solves the problem of the peer-to-peer connecting communication by making students and teachers as clients. They can communicate more directly without server on network. Analyze the requirements and functions of the system, makes overall design and divides the system into function modules, designs the group member management module, data processing module, transmission module ,resources sharing module and audio processing module.The group member management module gives the establishing, joinning and exiting, data processing module pieces various transferring data, JXTA uses input/output pipe to send /receive data, and uses piping to bind settle mechanism and define particular system message to carry on management to the members inside the set, for students's sharing the teaching resources on the teacher's machine,includes teacher's papers and homework etc.. The system provides the share function, each share contents has a content advertisement. The speech processing module sets one by one speech exchanges between students and teachers.Finally,the paper builds the test environment, the experiment expresses each module pieces to can work normally. The system doesn't need support of server, each peer on an equal position and sets each other independence with each other not interference, peers can communicate with each other through a pipe.
