This article analyses the behavior and evaluate the performance of an implementation of a fair traffic marker proposed in [1]. In this implementation, this marker makes use of the FRED (Flow Random Early Drop) fair buffer allocation algorithm. It exploits the duality between buffer allocation and token consumption in a token bucket marker in order to enforce fairness among different flows originated from the same subscriber network in a Differentiated Services domam, The results obtained show that fairness among flows from different traffic sources can be achieved by using this marker if FRED parameters are set correctly. Well-defined guidelines are established to help configure these parameters. Finally, it is shown that the fair marker cannot provide fairness in allocation of excess bandwidth.
