A Topology of Specialized Brokers for Computational Grid

Abstract-Computational grid comprises compute resources like PCs, clusters etc. The topology of brokers is very important in order to increase the scalability and fault – tolerance in a grid. The existing broker topologies are designed in such a way that the users and resource providers are bound to a single broker. Hence they have no choice in choosing the broker even if the brokers are biased. Moreover a single broker may not scale well if the number of entities bound to it increases and it also represents a single point failure. Hence a scalable and fault – tolerant topology of specialized brokers for computational grid is proposed in this paper in which the users and resource providers are not bound to any particular broker. So they are free to choose the broker according to their choice. The topology is designed in such a way that each broker is specialized in one type of resource. I
