Executive Summary

In this paper, the authors present an approach for supporting best effort traffic on an ECOFRAME ring network which has been dimensioned primarily for Guaranteed Traffic. This approach is reservation based, and is combined within the ECOFRAME MAC with the opportunistic access method used for Guaranteed traffic. The reservation method is intended to both protect the Guaranteed traffic and allocate fair shares of the excess resources to the competing Best Effort traffic flows. They analyze the performance of the proposed approach on 2 simple scenarios, i.e., a "Concentration" scenario where all stations send the same amount of traffic to a Hub on the ring, and an "Any-to-any" scenario where each station sends the same amount of traffic to each other station on the ring.
