Prediction-based AQM algorithm for diffServ network Academic Article uri icon

abstract

  • A new active queue management algorithm-PIO based on the prediction of the arrival rate in DiffServ networks is proposed. In PIO, the average arrival rate for IN packets and all packets in the next interval are predicted firstly. The PIO algorithm decides whether or not to drop the arriving packet according to the queue length for IN packets, the total queue length for all packets, the predicted arrival rate for IN packets and all packets in the next interval. Through the simulation, the PIO performances with respect to the stabilization of the queue, packet loss ratio and attainable throughput under the different subscription ratio and the different number of connections are analyzed. The simulation results indicate that PIO compared with RIO improves the stabilization of queue and reduces packet loss ratio efficiently whether the network is under-subscribed or oversubscribed, while providing statistical assurance for the bandwidth.
