Measurement-based Admission Control for Real-time Traffic in IP Differentiated Services Networks

The primary role of admission control in Quality of Service enabled networks is to control the amount of traffic injected into the network so that congestion is avoided. We consider IP Differentiated services networks able to support realtime traffic and we present a Measurement-based Admission Control (MBAC) scheme that uses only measurements of aggregate bandwidth without keeping track of any per-flow information. Through simulations we show that the admission control scheme is relatively robust to traffic heterogeneity and measurement errors and that it compares favorably against other MBAC proposals found in the literature.
