【摘要】 在分析已有广播通信机制的基础上,提出了一种新的移动Agent间通信算法。通过可靠扩散来实现广播,保证接收者至少接收一次消息;通过接收者主动请求消息,保证接收者只能接收一次消息。新算法保证可靠地完成消息发送以及消息传递的exactly-once语义,并在效率上有了进一步的提高。除了基本的算法,还讨论了一些改进的算法以及实现中遇到的一些问题。更多还原

【Abstract】 Broadcast is implemented byreliable flooding, which ensures that the receiver accepts the messageatleastonce. The receiveractively requests messages, which ensures the receiver accepts the message at most once. In virtue of the algorithm, the messages forremote mobile agents can be trustworthily accepted, and exactly-once delivery of the message is guaranteed, and besides, comparedwith the existing broadcast mechanism, it is more efficient. A number of enhancements to this basic algorithm and the issues in imple-mentation are also discussed.更多还原
