Abstract

Link-by-link flow-controlled virtual channels are proposed for asynchronous transfer mode (ATM) networks. The flow control mechanism efficiently uses leftover bandwidth after guaranteed traffic has been served, thus achieving high network utilization. Compatible with existing ATM standards, this proposal is called FCVC, (for flow-controlled virtual channels). Three increasingly memory-efficient credit-based flow control schemes, named N123, N123+ and N23, are described for implementing link-by-link flow control. These credit-based flow control schemes have been used in an experimental 622-Mbps ATM switch currently under development. Simulations based on the switch design have confirmed that the flow control mechanism is indeed able to provide sufficiently rapid feedback to let a network adapt to load changes and maximize its performance
