Study And Realization Of The Loading Balance On Middleware About Corba

The distributed object technology provides the powerful solution for software programming in network computing in 1990's. At present, the distributed object technology has been the core technology, for constructing services of application framework and software components , and it appears powerful living in large distributed application systems. With the progressing development of the network , many software programming must be running in some different structures about different network products, hardware products, network protocols. In the case, the middleware is happened. Middleware is a general services between the operation system and application software. The character of different structures between the operation system and network protocols is hidden and the difference in network hardware is also done. It makes application software run in different flat roof in sharply. The loading balance service is one of the attributions to the middleware, and it makes capability of the enterprise application step up a lot.The goal of loading balance service is the keeping consistence to each object in the systems, and it provides some services heavy and the others light. It also allocates command to each object according to the ability of loading, and it will increase the handles ability in whole system.In this thesis ,we research mainly the establishment of a real time% stable, and efficient loading balance service on the oriented CORBA technology middleware. When the client puts forward the claim, the loading balance service will select the best application service machine to offer service .The function of loading balance service is to making the each object service in the system to hold the balance, and making services expanded, and making the demanding changing continuously adapted quickly. It will make use of well to assign the system resources with the reasonable, realizing internal and valid usage in resources in system, avoid theefficiency of work suffering the influence in the whole system...
