This paper considers the implementation of ABR functionality in a queuing point located in the access part of the network. The developed Explicit Rate flow control mechanism is the result of a balanced trade-off between implementation complexity and link load efficiency. Also, the ABR end-system behavior is implemented on a Network Interface Card. At the same time, a solution is presented to realize ABR in a service multiplexer built around a shared-medium bus. Experimental and simulation results are presented which show the main characteristics of ABR. It is demonstrated that a cost- effective implementation of ABR performs very efficiently.© (1998) COPYRIGHT SPIE--The International Society for Optical Engineering.
