Optimization of the Bandwidth Distribution Scheme for Handling Topology Changes
Category: Networking and Communications
Overview The Bandwidth Distribution Scheme (BDS) was designed to combine the advantages of the Integrated and Differentiated Services models and to provide support for scalable per-flow Quality of Service. In the studies Hnatyshin et al. showed that the variation of the Bandwidth Distribution Scheme called the Exact Requested Bandwidth Range BDS (X-BDS), can support per-flow minimum bandwidth guarantees in a scalable manner. The X-BDS achieves per-flow QoS by maintaining aggregate flow requirements in the network core and distributing these requirements as needed. Based on the obtained information the edge nodes determine the fair allocation of available bandwidth among the active flows. This paper introduces an optimization which allows the XBDS approach to operate seamlessly in the event of network topology changes.
