Transition characteristics of congestion avoidance flow control: CEFLAR in ATM networks

CEFLAR is one way of realizing ATM-ABR with no cell loss. This paper shows that the transition characteristics of CEFLAR(transition time to achieve fair share), important when addressing network fairness, strongly depend on the acceleration-ratio coefficient, not the rate decrease factor or the distance between source and congestion estimation nodes. This paper also shows that the average throughput of a transmission line in transition degrades as the rate decrease factor decreases and as the distance between the source and congestion estimation nodes increases.
