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 report we present an algorithm, namely Intra-Domain Differentiated Routing (IDDR), which supports qualitative delay differentiation in IP networks. We review existing differentiated routing approaches and then introduce IDDR and present initial results. We demonstrate that using IDDR we can achieve qualitative delay differentiation for two classes of flows
