Evaluation of the virtual source/virtual destination-technique for available bit rate traffic in ATM-networks

This paper deals with the performance analysis of the virtual source/virtual destination (VS/VD) technique for ABR flow control. The VS/VD mechanism allows the segmentation of the ABR end-to-end feedback loop. We investigate the behaviour and performance of classical explicit rate switch algorithms in conjunction with VS/VD and give recommendations for improvements and alterations. The analysis is based on simulations of different network topologies and traffic scenarios.
