实时协同编辑中群组可靠性和容错研究

Group Reliability and Fault Tolerance in Real-Time Cooperative Editing

论述了在实时协同编辑系统中,协作站点的可靠性和协同会话管理的容错问题。给出一个会话管理器的查询算法,解决了协作站点或网络故障或长时间无操作生成等带来的系统可靠性与安全性问题。给出一个分布式备份模型解决了会话管理器的容错问题。并通过实验对相关算法的有效性进行了验证,为实时协同编辑系统的设计与实现提供了支持。

This paper describes the problems of reliability of cooperative sites and tolerance of session manager in a real-time cooperative editing systems on the Internet. A query algorithm based on session manager is presented to solve the reliability and security caused due to fault of sites or network, or long time no operation at cooperative sites. A distributed backup model is presented to solve the fault-tolerant problem of session manager. The validity of the above algorithms proposed in this paper is verified by a prototype system. It also provides the support for the design and implementation of the real-time cooperative editing systems.
