Abstract

The ABR service category of ATM architecture is a best effort service which aims to provide rapid access to unused network bandwidth at up to the link rate whenever the network bandwidth is available. As a result, the transfer characteristics provided by the network may change subsequent to connection establishment, and a congestion control mechanism is required. The ATM Forum has specified a congestion control infrastructure from where congestion control mechanisms like EFCI, EPRCA, ERICA and others have been proposed. The analysis of the underlaying infrastructure shows that, for the present switch and end-system behavior definitions, situations can arise when sources are allowed to transmit without control by the implemented congestion control mechanism. This study presents a quantitative analysis of the expected effects.
