Experiments of IP over ATM with congestion avoidance flow control: CEFLAR
義夫 梶山, Hideo Tatsuno, Nobuyuki Tokura · 2002
This paper demonstrates IP over ATM with congestion avoidance flow control, CEFLAR: congestion estimation feedback by limited acceleration-rate/ratio. A CEFLAR terminal adapter for STM-1 and CEFLAR nodes is developed to evaluate this characteristic. Experimental results confirm that CEFLAR can avoid the congestion state in ATM networks and control the transmitting rate without upper layer anomalies, IP packet loss and TCP re-transmission. Fair sharing of the available bandwidth is realized in local area networks. Lossless transmission on UDPI IP over ATM can be attained even in wide area networks of more than 1000 km in diameter.
