解决由Agent移动产生的可靠性通信问题.在分析已有方法的基础上,提出一种保证移动Agent之间可靠、高效通信的主动通信机制,并给出它的可靠性分析和通信效率分析.它能够在通信双方自由移动的情况下,将消息可靠、高效地从发送方提交给接收方,并承诺消息传递的exactly-once语义,为Agent通信语言等高层通信方式奠定了可靠的基础. To solve the problem of reliable communication caused by Agent mobility, an active communication mechanism to ensure reliable and efficient communication between mobile agents is proposed based on the analysis of existing methods, and its reliability analysis and communication efficiency analysis are given. It can reliably and efficiently deliver messages from the sender to the receiver and promise the exactly-once semantics of the message delivery, which establishes a reliable foundation for high-level communication such as Agent communication language.
