Abstracrt Asynchronous Transfer Mode (ATM) has emerged as most promising technology in supporting broadband multimedia communications. Congestion control plays important role in the effective and stable operation of ATM networks. In this paper, we described several existing rate based congestion control schemes namely, Explicit Forward Congestion Indication (EFCI), Enhanced Proportional Rate Co...

A control theoretic model for SBRM, a TCP variant based on congestion pricing theory, is presented in this article. We also examine the impact of instability on networks and show that instability causes decreased utilization. From our results we conclude that SBRM is more efficient than TCP Reno with RED queues.

In this paper we investigate the dynamic behavior of multiplexer queues for TCP traac in simple ATM networks. Our results are based on theoretical investigations which are proved by simulations. We propose a cell based queue length evaluation for TCP traac over ATM using service c ategorie UBR. In case of cell losses at the ATM multiplexer we estimate packet loss probabilities and discuss the i...
