Performance of Transport Protocols over ATM Networks

Abstract

The performance of file transfer applications running over an ATM infrastructure is investigated, taking into account both the impact of the ATM and AAL layer protocols, and the features of the adopted transport layer protocol. Two transport protocols are considered: TCP and XTP. The performance investigation is performed by simulation, using CLASS, a tool for the study of ATM networks at the cell and burst levels. The obtained results do not show a definite advantage of one transport protocol over the other, but rather different situations where either one performs slightly better or slightly worse.
