| Abstract: | 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. |
