The objective of this workshop was to exchange and to confront the technical approaches followed by the two projects on specifying Network Service Interfaces in their respective contexts. High Performance Networks offer advanced network services to users having different requirements. A Network Service Interface enables configuration, monitoring and orchestration of Network resources under particular agreements and policies to deliver on-demand end-to-end connectivity across multiple domains among the consumers (private companies, research labs, universities, etc.). The upper grid application middleware layer may request network services from one or more network service providers through the network service interface (NSI). The workshop developed on the recommendations for a generalized network service interface that can be called by different types of end user organizations, grid application middleware and by other network service providers. The grid + network infrastructure virtualization, the horizontal and vertical information exchanges were introduced, as well as the required messages and the extensions on the protocol engines were discussed according to different views: business, service, network, element and instances. During these two days of intensive technical exchanges, the agenda followed was:

The workshop allowed analyzing the similarities and the complementarities of the two projects for specifying the generalized network service interface taking into account the requirements in their respective contexts on one hand the business industrial applications and carrier transport networks (CARRIOCAS) and on the other hand the scientific applications and NREN transport networks (PHOSPHORUS).
