Abstract :
This paper presents a QoS solution for tactical networks with security consideration. Since encryption prevents the exchange of QoS information between the cipher text side and the plain text side, a partitioned QoS approach is presented. We present measurement based admission control (MBAC) as part of the plain text side QoS solution. MBAC uses real time measurements to regulate the flow of traffic entering a tactical core network based on a computed end-to-end congestion level. This paper discusses the benefits of using MBAC and the possible challenges of such an approach. The paper shows how the measurements can be used to create a Markov chain indicating the severity of path congestion. The paper also presents some simulation results from implementing MBAC in an OPNET model of the warfighter information network-tactical (WIN-T) network
