Based On Dcom Component Proxy Server Load Balancing Strategy

The requirement for load balancing is becoming harder and harder for distributed system. The purpose of this paper is to propose a low-cost load balancing strategy that is most useful for basic programmer. By means of analyzing DCOM structure and exploring the interface that is exposed for programmer, we come up with a solution based on component agent server, and then we analyzed its performance and its cost. It does make the most of current resources and makes it possible to enable current DCOM components to get load-balancing feature.There are many load-balancing methods, the emphasis of the paper is component agent server, and it's a usual method on network. It can improve the response efficiency of the sever. The focus of the method is intercepting the requests of clients, and chooses the best server. In this paper we use the agent component to intercept the request and in the agent server we choose the best server. In this paper we use response time(ping) to determine the best server, we design a background thread to maintain the response time of the server cluster.We provide a common solution; it has nothing to do with specific code the solution modify none of the code .the only thing for the clients to do is configuration, it is like using dcomcnfig to configure COM component.
