In the future, grid application developers will be able to schedule lightpaths provided by commercial network providers. In this demonstration, a large-scale nano-quantum application utilizes both computational resources and an optical path. The application uses Ninf-G middleware, which calls on a Scheduler that calls on a Lambda Path Resource Manager to request an optical path in a GMPLS control environment, specifying the end nodes’ locations and other requirements, such as bandwidth. GMPLS, in turn, programs physical OXCs (optical cross connects) to set up end-to-end lightpaths over multiple domains. The goal is to define a standard interface between the grid and the optical network, which can be used as a tool for realizing emerging new commercial services that both application service providers and commercial network companies will accept.
