Architecture for Dynamic and Fair Distribution of Bandwidth

The problem of fair distribution of available bandwidth among traffic flows or aggregates remains an essential issue in computer networks. This paper introduces a novel approach, called the Exact Bandwidth Distribution Scheme (X-BDS), for dynamic and fair distribution of available bandwidth among individual flows. In this approach, the edge routers keep per-flow information, while the core routers maintain the aggregate flow requirements. The XBDS approach employs a distributed message exchange protocol for providing network feedback and for distributing aggregate flow requirements among the nodes in the network.
