Adaptive Remote Rate Control Using Extrapolation and Correction Mechanism for Periodic Notification of Link Utilization Ratio

SUMMARY A new adaptive rate control with congestion prediction is developed that is highly robust against long propagation delays. It minimizes the network performance degradation caused by the delay based on prediction by extrapolating past data and correction using new notification. The simulation results show that our proposed control maintains high throughput and a smaller buffer even in long propagation delay networks, like ATM-WAN.
