1. Short overview
The SCoPE project aims to create a metropolitan grid infrastructure, gLite based, among the departments of the University of Naples Federico II .
In this environment we have implemented and deployed GlueDomains, a network monitoring framework, in order to provide the measurements needed to support the network aware meta-scheduling algorithms and the QoS of the network services. In this work we show as the use of network measurement can improve the performances in a the general purpose Grid.
The impact of the GlueDomains deployment is to optimize the use of the network resources and to provide a growing of the general performances during the data transfer operations.
The metropolitan wide implementation of a network measurement system, also offer the opportunity to study and to test the cooscheduling algorithms and to understand how the use of the network parameters can improve the performance of the "best effort" based Grid systems.
The the SCoPE framework allows having an excellent and complete testbed platform in which deploy and evaluate the new Grid services. So that the expected impacts due to the diffusion of this experience, will be related to the progress of the know-how about the potentiality to use the network measurements in more large environments.
4. Conclusions / Future plans
The GlueDomains Framework has been deployed in the main sites of the SCoPE infrastructure and the measurements are in used by users and developpers for monitoring the network reliability and to test some network aware cooscheduling algoritms. Some new measurement tools are ready to be added to the framework. In the immediate future we plan to allarge the testbed and add new measurements tools to the environment with the feedback of the users and developers.
