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. We compare our adaptive scheme with two previously relevant proposals. The comparative performance evaluation carried out verifies that our scheme outperforms the two previous proposals in terms of both carried traffic and convergence speed to new operating conditions. Other key features of our scheme are its simplicity, its oscillation-free behavior, and its integrated strategy to deal with multiservice scenarios.
