Research and Implementation of Collaboration Computing Model Based on Proxies

Aiming at he scalability of real-time collaboration computing which is large scale and multiple data sources, a three-layer architecture model is presented after analyzing the shortcomings of existing models.Then the method of constructing overlay layer is given, namely, by collecting servers and deploying some proxies in every autonomy system, and kernel proxies are selected in every autonomy system.The kernel proxies run Pastry protocol and form overlay layer.Experimental results show that the model has good real-time performance and scalability.
