An implementation study of a dynamic inter-domain bandwidth management platform in DiffServ networks

In this paper, we assess the scalability and efficiency of a scalable Bandwidth Manage-ment Point (BMP) for guaranteed Quality-of-Service in Diffserv networks. Our BMF ' uses centralized network state maintenance and pipe-based intra-domain resource management schemes that significantly reduce the admission control time and minimize the scalabil-ity problems present in prior research. We have designed, developed and implemented an enhanced Simple Inter-Domain Bandwidth Broker Signaling (SIBBS) protocol for inter-domain communication. The BMP uses dynamic inter-domain pipes to handle inter-domain provisioning and dynamic provisioning schemes to increase signaling scalability. To assess our BMP implementation in terms of signaling scalability and effective resource utilization, we conducted experiments on a test-bed demonstrating how a BMP substan-tially increases resource utilization and scalability while requiring minimum changes in the underlying infrastructure
