Bandwidth on Demand Services for European Research and Education Networks

The Joint Research Activity 3 of the European project GN2 aims to specify and develop a prototype for a Bandwidth on Demand service destined to operate in a multi-domain environment using heterogeneous transmission technologies. This paper reviews the project's key achievements (general architecture and early prototyping results) and reports on current research and development areas (abstract network description, technology stitching and path finding) with a particular focus on inter-domain issues.
