| Nowadays, Grid becomes an important information technology in the world, which aims to realize high performance resource sharing and cooperation and to eliminate information and Resource Island. Grid looks like a virtual supercomputer composed by the computers, which located in different places and connected by internet, the resources in grid, such as memory, data, information, software, knowledge and specialist resource etc, can be shared each other.E-mail is a successful example of the Internet application as a new communications tool. It has been born before long, but it has infected all aspects of the human-being deeply including the working and the living. However, E-mail gives a lot of advantages for ill-message spreading abroad. Nowadays, it becomes a headache problem for many users because of all kinds of spam appearing on Internet.The used antispam technology mainly aims at the single machine or individual, the antispam resources cannot be share. The memory and compute capability of the computer system are antispam recourse too. The point of grid technique is resource sharing and cooperative working, so it will make up the insufficiency of the present antispam technique. Service grid is the grid emphasized on service. It integrates the separate resource into grid service and offers the accordant interface to access resource. Service grid manages the registration, allocation and other operations. It provides dynamic services, and can adapt the dynamic environment.In this paper, through studding E-mail system and service grid system, the paper will try to design a distributed anti-spam system using the ability of resource sharing and heteromerous of grid, and will realize some functions. Entire system includes the antispam client, antispam server, and dispatcher mainly. The paper describes how to creat the grid service, how to deploy the grid system and how to design the dispatcher.For as far as possible accurate difference the spam mail and regular mail, the paper analyses the main current anti-spam technology. Union the grid system's characteristic property, the paper will try to design the distributed Beyes solution, which is able to record spam mail's characteristic. And pass the data share, the grid system will finally realize distributed Beyes filter. The system which centralizes the resource of servers in the GT container can filter spam in the whole of network which makes the ability of anti-spam better. |
