Abstract
Differentiated services architecture is receiving wide attention as a scalable mechanism for providing different levels of Quality-of-Service (QOS).Recent studies, both analytical and simulation-based, have shown that the provided bandwidth in such an architecture may differ from the contracted rates.In this paper, we propose an active resource management approach that brings the provided service closer to the target rates. The proposed approach, SACRIO, actively allocates available excess bandwidth through localized packet remarking within a router. It is shown that SACRIO is simple to implement within the diff-serv architecture. It is also shown that the packet handling cost remains O(1) with SACRIO. SACRIO is shown to be quite effective through simulations.
