The Key Technology Of Grid Service Resource Search Engine Based On Mobile Agent

Now the Internet is developing towards the next generation network that is the grid based on fully resource sharing. The grid is a network integration technology for sharing distributing computing resource. The first thing to implement a gird resource sharing is grid resource's definition, registration, finding and searching. Building a facility, fast and accurate grid resource search engine will be the key for users to use computing grid resource quickly, so it is very important to study the resolving methods. The mobile agent technology is a new distribute technology and it's main idea is dispatching the system's separate executing programs to the data storage context for usable resource. In grid using mobile agent can find grid service and resource quickly and accurately. The ways to publish and register grid service are UDDI service register center and grid service inspection language. By diagnosing the distinguish between the two service finding methods, it can be found that the merit of grid service inspection language is net crawlet used freely. Search engine can distribute search programe to different computers by using mobile agent. So it can reduces the consummation of software and hardware.Using mobile agent to process grid searching requests in parallel model may enhance searching speed. In search engine the job of finding service resource is completing be search agent, but the difficulty is the way to controll search agent. The agent smart clone technology and propriate security system can help to make mobile agent system run much more safely and efficiently.
