PHOSPHORUS: single-step on-demand services across multi-domain networks for e-science

The Phosphorus project focuses on delivering advanced network services to Grid users and applications interconnected by heterogeneous infrastructures. The project is addressing some of the key technical challenges to enable on-demand end-to-end network services across multiple domains. The Phosphorus network concept makes applications aware of their complete Grid resources environment -computational and networking- and its capabilities. Phosphorus enables and tests dynamic adaptive and optimised use of the heterogeneous network infrastructure interconnecting various high-end resources. The project will demonstrate on-demand service delivery across access-independent multi-domain/multi-vendor research network test-beds on a European and worldwide scope. Phosphorus enhances and demonstrates solutions that facilitate vertical and horizontal communication among applications middleware and the network resources across different domains, managed by existing Network Resource Provisioning Systems (NRPS), or domains that integrate a new Grid-GMPLS (G2MPLS) Control Plane, both under a new AAA architecture to support policy based on-demand network resource provisioning. This G2MPLS extends ASON/GMPLS in order to provide part of the functionalities related to the selection, co-allocation and maintenance of both Grid and network resources, by exposing upgraded interfaces at the UNI and E-NNI network reference points -i.e. G.OUNI and G.E-NNI-. The project outcomes are going to be demonstrated in a worldwide test-bed.
