Realization Of Collaboration Communication Platform Based On Shared Space

With the great improvement of PC performance and the fast growth of Internet speed, it has become a popular issue how to efficiently use the computer and internet resources. Collaboration calculation will be the coming application paradigm, Service based communication method is a key technique of collaboration system, and it's very important to provide transparent, automatic and security shared method. This paper reviews researches on service based collaboration system; and a shared service space framework also been built to support collaboration applications.This paper will research how to implement a collaboration communication platform based on shared space, which includes following important parts: real time communication, P2P, message management, site management and shared space management.(1) Message based communication system.Different communication protocols are used for data exchange in current collaboration system and the collaboration applications must deal with the data according to different communication protocols.Message based transparent communication system is introduced in this paper to solve this problem. System will automatically select different communication type and exchange data by message according to the network situation.(2) Message based service system.General collaboration system needs to analyze the data transferred by the network, to share data between collaboration nodes, collaboration application also need to deal with and organization the data.Message based service system is introduced in this paper to solve message exchanging issue. All the cooperation actions can be separated as service request and service response, service consumer only need to send service request message to service provider; service provider will deal with the request message and send the result back by response message.(3) Share data by shared space.It's hard to use the collaboration resources in the general collaboration systems, and it's expensive to develop collaboration applications. Share space is provided to solve these issues. Share space provide transparent, automatic information sharing service, and also support offline operation, so the application can easily access the collaboration services.(4) Application research.PIDS is built on this collaboration system, which consume the collaboration service and share space service to co-operate information and operate railway station service information between some PIDS applications.
