Performance evaluation of TCP over ABT protocols.

ABT (ATM block transfer) has been considered an efficient protocol for high-burst data transmission in ATM networks. The characteristics of ABT in the ATM service class have already been investigated. For practical applications, however, it is necessary to consider an upper layer having its own congestion-control mechanism, apart from the ABT. This paper analyzes the characteristics of a TCP (transmission-control protocol) for the Internet which has become very popular recently, when this is used for the upper layer of the ABT. It is shown to be possible to separate the congestion control and the error-recovery service, since the congestion control is carried out effectively in the ABT by the retransmission mechanism of TCP, without using the congestion control of TCP. However, for high performance it is necessary to tune the retransmission timer of the TCP as discussed in this paper. © 2002 Wiley Periodicals, Inc.
