移动Agent系统中消息机制的设计与实现

Design and Implement of Message Mechanism on Mobile Agent System

在描述移动 Agent系统中消息对象和消息队列设计的基础上 ,通过流程图说明整个系统中消息机制的实现。消息机制是 Agent通讯的主要手段。通讯时 Agent传递消息对象 ,每个 Agent还要维护一个消息队列 ,用于存储接收到的待处理消息。实现消息机制时 ,系统定义专门的 messagethread线程来处理消息 ,并规定m essagethread线程的优先级策略。

The message object and message queue in a mobile agent system are introduced. The realization of message mechanism of the mobile agent system is explained by using flow chart.Message mechanism is the main means of agent communication.In communication the agents send special information:message object.In addition,each agent still has a message queue using for saving received treating message.The system defines the specialized messagethread for message processing and stipulates messagepriority strategy of the messagethread.
