Analytical Model of Modified Traffic Control in an ATM Computer Network

Abstract

The ABR class of ATM computer networks uses feedback information that is generated by net switches and destination and is sent back to a source of data to control the net load. A modification of the standard traffic management of the ATM network is presented, based on the idea of using RM cells to inform the source about congestion. An analytical model of a net switch is designed and mathematical relations are presented. The probability of queueing is considered. The analytical model of the switch was constructed for the purpose of analysing the network behaviour. It is used for investigating of cells passing through the network. We describe the model below. The submitted analytical results show that this method reduces congestion and improves throughput.
