The Phosphorus [1, 2] project focuses on delivering advanced net-work services to Grid users and applications interconnected by heterogeneousinfrastructures. The project is addressing some of the key technical challengesto enable on-demand end-to-end network services across multiple domains. ThePhosphorus network concept makes applications aware of their complete Gridresources environment -computational and networkingand its capabilities. Phos-phorus enables and tests dynamic adaptive and optimised use of the heterogeneousnetwork infrastructure interconnecting various high-end resources. The projectwill demonstrate on-demand service delivery across access-independent multi-domain/multi-vendor research network test-beds on a European and worldwidescope. Phosphorus enhances and demonstrates solutions that facilitate verticaland horizontal communication among applications middleware and the networkresources across different domains, managed by existing Network Resource Provi-
