This paper presents an original analytical model for a finite buffer queueing system with active queue management (AQM) where the dynamic channel conditions are captured by Markov-modulated Poisson processes. The model derives the close-form expressions of performance metrics including the mean number of packets in the system and in the queue, throughput, response time, delay, packet loss probability...
Active queue management (AQM) coupled with differentiated scheduling mechanism is an important and promising scheme for congestion control and quality-of-service (QoS) guarantee in communication networks. This paper develops a new analytical performance model for priority-based AQM subject to heterogeneous bursty traffic modelled by Markov-modulated Poisson processes (MMPP) and non-bursty traffic...
Various buffer management and congestion control mechanisms have been proposed to support differentiated Quality-of-Service (QoS) requirements due to the heterogeneous properties of real-world network traffic and applications. Active Queue Management (AQM) with multiple thresholds, which starts dropping packets before the queue becomes full in order to notify incipient stages of congestion, is a promising...
Active queue management (AQM) with multiple thresholds is an effective mechanism of buffer allocation for differentiated quality-of-service (QoS) of heterogeneous traffic. This paper develops an original analytical model for a finite buffer queueing system with AQM under two heterogeneous classes of traffic which are modeled, respectively, by the non-bursty Poisson process and bursty Markov-modulated...
