The JRA3 Activity of GN2 project is heading to implement a multi-domain, heterogeneous technologies bandwidth reservation system for end users. During the design and implementation efforts of the last two years, project participants have come across a set of problems and decisions that are common for reservation systems. Having in mind the specific project objectives, supported by the knowledge and experience from similar efforts around the world, the JRA3 team has been working to identify the most suitable, and flexible approaches for inter-domain Bandwidth-on-Demand (BoD) provisioning issues. This paper presents the assumptions and decisions made so far, their background, pros and cons, and their consequences for the further project development.
