Performance Comparison of Resilient Packet Ring (RPR), Packet over SDH/SONET (POS) and Gigabit Ethernet (GE) for network design

This paper provides a systematic approach for determining the best of three emerging network technologies – RPR, POS and GE for any given network with a set of basic network requirements. This approach uses an extensive set of evaluation criteria including raw experimental data, a realistic pricing model, scores and weights. All experimental results presented in this paper come from actual testing on a network testbed, which makes conclusions much more credible than pure simulation may offer.
