Meta-Brokering requirements and research directions in state-of-the-art Grid Resource Management

Grid resource management is probably the research field mostly affected by user demands. Though well-designed, evaluated and widely used resource brokers, meta-schedulers have been developed, new capabilities are required, such as agreement and interoperability support. Existing solutions cannot cross the border of current middleware systems that are lacking the support of these requirements. In this paper we examine and compare different research directions followed by researchers in the field of Grid Resource Management regarding the level on top of brokering approaches. Our proposed meta-brokering approach means a higher level resource management by enabling communication among existing Grid Brokers and utilizing them. We state the requirements of this novel middleware service, and define a general meta-brokering architecture to be implemented as a Service Oriented Knowledge Utility (SOKU) in future generation grids.
