Abstract
Experience-based admission control (EBAC) is a hybrid approach combining the classical parameter-based and measurement-based admission control schemes. EBAC calculates an appropriate overbooking factor used to overbook link capacities with resource reservations in packet-based networks. This overbooking factor correlates with the average peak-to-mean rate ratio of all admitted traffic flows on the link. So far, a single overbooking factor is calculated for the entire traffic aggregate. In this paper, we propose type-specific EBAC which provides a compound overbooking factor considering different types of traffic that subsume flows with similar peak-to-mean rate ratios. The concept can be well implemented since it does not require type-specific traffic measurements. We give a proof of concept for this extension and compare it with the conventional EBAC approach. We show that EBAC with type-specific overbooking leads to better resource utilization under normal conditions and to faster response times for changing traffic mixes.
