| | PDF (64 KB)

Summary form only given. This paper argues that, for high-speed networks such as ATM, it is important to use link-by-link flow control on a per virtual circuit (VC) basis. It can effectively control congestion and maximize network utilization. Three progressively memory-efficient, credit-based flow control schemes, called N123, N123+ and N23, are described, and simulation results of these schemes ... View full abstract»
