A Three Level Broker Framework for Global Service - Oriented Utility Grid

The topology of brokers is very important in a global service-oriented utility grid for serving both the users' and service providers' interests. A three level broker framework is proposed in this paper in which the brokers are not bound to any particular domain. Hence the users and service providers are free to choose the broker they wish. The framework is designed in such a way that the brokers are organized into three levels. A Level 1(L1) broker is assisted by many Level 2(L2) brokers and a L2 broker may be assisted by many Level 3(L3) brokers. Users interact with LI brokers only. L2 brokers are classified according to the type of resources. L3 brokers are classified based on the resources under a L2 broker. A L1 broker contacts L2 brokers, which in turn may contact L3 brokers for selecting the requested resources.
