We propose a novel adaptive reservation scheme designed to operate in association with the well-known Multiple Guard Channel (MGC) admission control policy. The scheme adjusts the MGC configuration parameters by continuously tracking the Quality of Service (QoS) perceived by users, adapting to any mix of aggregated traffic and enforcing a differentiated treatment among services during underload and overload episodes. The performance evaluation study confirms that the QoS objective is met with an excellent precision and that it converges rapidly to new operating conditions. These features along with its simplicity make our scheme superior to previous proposals and justify that it can satisfactorily deal with the non-stationary nature of an operating network.
