Quality of Service delivered to Grids by packet-switched networks, is one of the most important factors affecting performance and efficiency of both Grid applications and middleware.The use Virtual Private Network services can improve the overall performance of Grids in many respects.In this paper, we show how the security, privacy and Quality of Service offered by scalable on-demand VPN services can be applied in large-scale Grid scenarios.We propose a novel network resource abstraction for resource discovery of on-demand Virtual Private Networks.It is implemented in a Grid Information Service prototype which was successfully tested both on dedicated infrastructures and production networks.1
