By making an analysis on the information communication mode in the network virtual community using mainly the society network matrix analysis method,the article sums up basic characteristics of the group of the virtual community,and at the same time makes a verification analysis on how these characteristics affect the CMC information transmission in the virtual community and presents means and countermeasures to control information communication.
At present,information management research mainly focuses on the following subjects:information integration system,new type preference service,personalized information service,information sharing system,library website,digital library,digital communication platform and management innovation.
Recently, the 21-centery - oriented society development, information network communication, information resource exploitation, the constitution and usage of network composed the new environment of user information demand.
We should construct the new ideological system of editing, intensify the consciousness of position,build the new publishing system of edition,increase the content of super technics, build the new system of school newspaper's communication,boost the networks′ cooperation and advance development of university newspaper's information network.
When either a node or a link in a fault-tolerant network fails, the communication from one node to another using this faulty element must be sent via one or more intermediate nodes along a sequence of paths determined by this routing.
An important and practical problem is how to choose a routing in the network such that inter-mediate nodes to ensure communication are small for any fault-set.
By using DR estimation of the state, the effect of communication delays is overcome.
A new dynamic routing algorithm based on MANET in LEO/MEO satellite networks, which fits for the LEO/MEO satellite communication system, is proposed.
Dense wavelength division multiplexing (DWDM) system is the ultimate selection as an optical communication system because of its high speeds and capacities.
