Scalability of inter-domain edge tunnels using bandwidth brokers: a region-based approach

In this paper we present a scalability study on inter-domain tunnels using bandwidth brokers. Our approach is based on collections of autonomous systems called regions. We analyzed our architecture through simulation. Our analysis results show that scalability of the approach depends on the size of the regions, and as the size of the region decreases, scalability of the approach increases. We show that our architecture increases state scalability as well as signaling scalability for Diffserv networks.
