本文提出了一种新的通信智能体，称为通用对象请求智能体，通过超时技术提高开放分布式对象系统的客户／服务器模型通信的可靠性．本文提出通信智能体模型的目的在于提高请求的可靠性．在这个模型中，应用由时间段事务处理支持的反馈机制，对服务器完成请求的过程有更大的控制能力，并且客户以超时操作作为避免死亡的最后手段，从而使系统整体性能更加可靠.

This paper proposes a new communication agent，called CORA(commonobject request agent)．The purpose of this approach is to improve the reliability of commu-nication using time-out in open distributed system based on client/server model．In CORA model, the application client could have more control over server'S processing the request through the feedback mechanism of timesegment transaction．and provide time-out's handling for preventing the bad propagation of the partial failure SO that the whole system becomes more rohust．
