Emerging high-end applications require a rich set of network provisioning services that go beyond the traditional source-destination, end-to-end path service. They also require high-bandwidth and high-quality circuit services that only optical networks could offer. In this paper, we first analyze some repive high-end Grid applications and abstract their needed generic set of network provisioning services. Then we provide some preliminary analysis on the routing, resource allocation, and survivability mechanisms of these generic network services. The focus is on the temporal and spatial extensions over the traditional network service definitions. We also introduce our implementation and experimental activities within the Enlightened Computing project and present ongoing research work.
