Control architecture for tuning intensity and burstiness of traffic

In this paper we explore a control architecture that can implement active queue management and transport control. For queue management, two independent metrics-utilization factor ρ and burstiness factor η, are used to characterize queueing congestion state. Consequently, two information bits are generated to guide the sender´s adaptation of traffic intensity and burstiness. Transport control is achieved through the combination of a window and a token bucket that can respond to the two-bit feedback properly. Preliminary simulation study shows that this architecture can easily achieve specified throughput and constrain both queueing delay and delay jitter within specified bounds.
