Synchronized Process Realization in the Computer Real-time Collaborative System
Peng Wu · Journal of Hangzhou Dianzi University · 2006
As a kind of distributed system that supports human-computer interaction,real-time collaborative design systems should be highlighted in practical implementation.When we are developing a real-time collaborative system,three requirements of real-time,distribution and unconstraint are to be fulfilled.Because of the concurrent operations from the users and the transmission latency of the network,some concurrent problems take place during the collaborative work.During the cause of the collaborative design,if a site joins the system late,or a site disconnect from the system abnormally and rejoins in,concurrent problems will occur.As a prototype of real-time collaborative system,the CoDesign system implements some algorithms proposed from others.This prototype is tested under the simulation of various situations happen in the cosmically usage of the collaborative system.
