Performance of a deterministic flow control scheme for data traffic in ATM networks

This paper presents certain preliminary performance results obtained using a scheme called deterministic quantised rate based flow control for data type traffic in ATM networks. The scheme has been based on a new paradigm of congestion control for data traffic in ATM networks, which tries to guarantee a certain QoS for such services as well, while trying not to effect the QoS of other services supported within the network. The performance of such a scheme has been evaluated using the OPNET simulation tool using a simple model of 2 VBR video sources and 2 ABR data sources. The results indicate an improvement in the traffic pattern within in the network at the same time providing a better environment for other services.
