Examining The Benefits Of A Hybrid Distributed Architecture For Bandwidth Brokers

In this paper the issue of the architectural organization of a Bandwidth Broker with respect to the distribution of functionalities among separate entities is examined. We discuss the benefits of a distributed versus a centralized architecture and study some of the most important implementations. We also present a novel design proposal that builds on our earlier work on the admission control module of a Bandwidth Broker and introduces it in the framework of a distributed Bandwidth Broker architecture. Our conclusions are supported by a series of simulated experiments that we analyze.
