Design and implementation of a Grid Network-Aware Resource Broker

The paper presents the design and the development of a Grid Network-Aware Resource Broker. It enhances the features of a Grid Resource Broker with the capabilities provided by a Network Resource Manager. The innovative contribution of the presented integration is the possibility to design and implement new mapping/scheduling mechanisms to take into account both network and computational resources.

Currently, Grid applications arc developed for a network offering only a best effort packet delivery set-vice. Nevertheless, High Performance Computing applications with Quality of Service requirements stress the capabilities of the interconnecting network of the target Grid infrastructure. Therefore the application runtime environment must interact, through a Grid Resource Broker, with a Network Resource Manager to obtain information about the network and to reserve network resources among the computational resources that will host the execution of applications.
