Buffering concepts for ATM switching networks
Erwin Paul Rathgeb, Thomas H. Theimer, M. Huber · 2003
The authors study various buffering strategies for switch fabrics of the Banyan type, where the buffers are located in the individual switching elements. The influence of the different strategies on the performance of the network has been evaluated under equivalent conditions to allow a comparison of the results, and the packet loss probability for networks constructed of switching elements with input buffers has been analyzed. The investigations indicate that significant performance improvements can be achieved by applying advanced buffering concepts. The choice of the best buffering strategy depends on the size of the switching elements as well as on economic and technological constraints.>
