Opis :
Providing quality of service (QoS) into the networks based on the packet switched technologies, as ATM and IP, is currently the challenge for the military communi cation system designers. The main element for achieving QoS capabilities is to implement effective admission control (AC) function, which regulates the volume of submitted traffic to the network. The traditional approach for the AC is that it is invoked by each call requesting QoS. As a consequence, the call set-up latency is increasing and, in addition, the signaling traffic in the network is growing. This paper proposes a simple AC method that is based on the online traffic load measurements and assumes that the AC is involved only when the load exceeds a predefined threshold. As a consequence, for most of the connections the AC is not necessary to be executed and this causes lower set-up phase duration and limits the volume of signaling traffic. The numerical results showing effectiveness of the approach are included and compared with traditional AC performing.
