Bank Grid Computing Architecture Research Based On OGSA

Grid computing plays a core role for the grid system to provide services, mainly consisting of Meta Computing, P2P Computing, Distribute Computing. Such an computing focuses on Organic combination of so many Discrete computing resources, so to make those resources a computing system with powerful computing and coordinating competence. As a basic service industry of informational society of our time, banks serving billions of clients with services of a great variety every day which often involve themselves with "business peak" in rush time. In consideration of that, this paper proposes apply the most popular computing mode-Grid Computing to the bank, and builds the Bank Gird Computing System based the OGSA with open Grid system, the system is sharing resources and computing coordination.The center of the Bank Gird Computing System is the PBC (People Bank of China) and converges the various computing resources coming from many different banks, such as servers, host computer and financial mainframe and the like to provide the banks with full computer resource. The system includes the financial application level, the web level, the middle level and the resources level in order to correspond, put out and control the resources in the whole.Mentioning resource management mechanism in the Bank Grid Computing System, the concept of 'Bank Management Domain' is introduced, each one as a self-controlled computing system. In addition, Bank Management Domain is classified into the inner area and the out area, the inner area is under resource centralizing management, while the out area all use RID to publish resource description information. Self-controlled computing system like these are scattered in position but are under consistent coordination of the Bank Grid Computing System. After Bank Management Domain, the second concept of 'Banking Resource Pool' was introduced about which a lot of words are pumped into. Such words remark on the detailed portrayal of the resource pool's performance, the scheduling mechanism for the resource scheduling level and user scheduling level in the mode of the two-level resources management are presented .The realization of the mode of the two-level resources management under different environments with the assistance of 'Static Critical Path with Task Migration'. As for the security management mechanism, with the assistant conception of the mode of the two-level resources management, the scheduling mechanism, and the Bank Management Domain, the paper proposes the conception of Security Model for Access Control, and descript it formally.Finally, in order to examine the theory of the bank gird computing system, we construct a grid computing system based on OGSA, and simulate the bank computing service under the grid environment.
