Intra-Domain Delay-Based Quality of Service Using Differentiated Routing

Differentiated routing is an approach to providing service differentiation in networks, a field that is currently receiving significant research attention. In this paper, the authors present an algorithm, namely Intra-Domain Differentiated Routing (IDDR), which supports qualitative delay differentiation in IP networks. They review existing differentiated routing approaches and then introduce IDDR and present initial results. They demonstrate that using IDDR, they can achieve qualitative delay differentiation for two classes of flows. The demands placed on computer networks continue to increase, with increased development of multimedia applications and distributed data processing and retrieval systems.
