Abstract: The steadily rising demand for multimedia and data services, the falling cost and omnipresence of Ethernet and the maturity of PON (Passive Optical Networks) technology, promise to radically change the landscape in the local loop. Standardization efforts under way for the specification of Passive optical networks (PONs) at Gbps speeds concentrate on the transportation of bursty IP traffic. In this paper, the implementation in hardware of the MAC controller which governs the upstream bandwidth allocation taking into account the QoS requirements of the user flows is presented. It employs the bandwidth arbitration tools of the FSAN/ITU G.984.3 standard and assigns the 1.24Gbps of the upstream link down to a resolution of a byte with QoS differentiation.
