摘要： 从分布式地理信息系统的应用出发，考虑到在一次调用中客户提出多个服务请求的情况，提出了多对多异步RPC模型，讨论了该模型的各个组成部分的功能及调用关系，并进一步阐述了运用线程池和异步Web Services技术实现模型的方法.

Abstract: Beginning from the application of distributed geography information system and considering the situation in one call that a client requests several services, the model of multicast asynchrony RPC was pro-posed. And the functions of each component and their call relationship each other were discussed. Finally, the method based on the thread pool and asynchrony Web Services was introduced to implement this model.

Key words: RPC, web services, agent, multi-threads, distributed GIS, RPC, web services, agent, multi-threads
