基于移动代理技术的网格搜索服务的研究与实现

网格服务是网格的中心思想，但OGSA描述的网格服务是静止的，固定在能提供此服务的网格主机上，不具有移动性，由此带来了持续连接、带宽浪费、智能性不高、调用繁琐等缺点。本文在深入研究Globus网格和移动Agent技术后，将移动Agent应用于Globus网格服务的实现中，提出了基于此思想的网上信息搜索服务的模型及其原型系统的实现方法。这种网格服务具有灵活的可移动性，解决了静止服务产生的上述弊端。

RESEARCH FOR SEARCH SERVICE OF GRID BASED ON MOBILE AGENT

Grid Service is the key thought of Grid.But describ ed in OGSA,Grid Service is static,it is fixedly installed on the Grid node mach i ne that can provide this service and has no mobility.This static service results in many drawbacks such as continuous connection,waste of bandwidth,less intelli gence and overload with services calling.After deep research on the framework an d implementation of Globus and Mobile Agent techniques,this paper brings mobile agent into the implementation of grid service,showing a prototype system for inf ormation searching on WEB based on the method.Such grid service is more flexible with mobility which solves the disadvantages that caused by static service.
