Comparison and analysis of measurement and parameter based admission control methods for Quality of Service (QoS) provisioning

Admission control methods are important tools for ensuring the Quality of Service (QoS) of flows within a network by allowing additional flows only if their addition does not disrupt current flows. Two common admission control methods are Parameter-Based Admission Control (PBAC) and Measurement-Based Admission Control (MBAC). We have implemented versions of both methods in our Network QoS Management framework, which provides a QoS API for QoS-aware application to request network resources. We have made evaluations within our testbed environment of our MBAC implementation against the more traditional PBAC method in order to compare the efficiency of network utilization between the two methods.
