Research On Service Grid And It's Application In The Field Of Anti-Spam

Grid is a new generation infrastructure based on internet, which called the third revolution on network after internet and www(world wide web). Grid looks like a virtual supercomputer composed by the computers, which located in defferent 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. Grid technology is still on researching now, but the scholars have reached lots of great achievement.At present, junk mail becomes disaster ,not only it disturb the studying and working of the individual user or employee, but also it bring the negative influence on our country and society.The voice of resist the spam is more clearly ,and supported by the computer users from the world. Many countrys, such as USA, Japan, sponsor to resist spam by the way of resource sharing and cooperative working.The used antispam technology aim at the single machine or individual,the antispam resources cannot be share, the resource includes the blacklist,ip address of mail server, filter rules, as well as learned knowledge of bayes algorithm, the memory and compute capability of the computer system are antispam resoures too. The point of grid techinque is resource shareing and cooperative working,so it will make up the insufficiency of the present antispam technique. Service grid is the grid emphasized on service, it integrate the separate resource into grid service and offer the accordant interface to access resource. Service grid manage the registation ,allocation and other operations.it provide dynamic services,and can adapt the dynamic environment.so the research and application on grid service in the antispam field have very strong theory and practice significance.Firstly,the paper introduce the basic concept of grid technique and web service technique.Service grid is the combination of grid and web service ,with the progressive development of them. Secondly,the third chapter instroduce the basis of grid — architecture, grid architecture changed from sandglass modal to OGSA .and the important specification of ogsi is replaced by wsrf. Finally, the paper illuminate the system design of the antispam service grid in detail, how to implement the antispam grid serivce in the .net platform useing the wsrf.net 2.0 tools, and how to develop the client program to invoke the antispam grid service.
