| 摘 要： | 提出了一种用户广域网环境下的客户服务器系统的资源使用状态自维护机制，使客户在保存自身对资源的使用状况和有关状态的同时定时地将其通知服务器，从而达到应用系统的健壮性和状态参数的一致性。在此基础上，利用Perti网对具备该机制的客户服务器系统进行了建模，对正常和各种异常情况下系统的自维护特性进行了分析，最后介绍了该机制在一个实际的客户服务器系统中的应用情况。

| Abstract: | A self-maintenance mechanism of the state of resource usage in Client/Server System over wide area networks is put forward. Client retains the set of parameters about its usage of resource and related states. At the same time, it passes the set of parameter on server periodically. Thus the robust of application system and the consistency of state parameters can be attained. The Petri Net based Modeling of the Client/Server System that adopts this mechanism is described and the analysis of Self-Maintenance in this kind of system are also provided. Finally, the application of this mechanism is introduced. |
