RESUMO

We propose new framework for traffic modelling, policing and scheduling in Ethernet Passive Optical Networks. This framework aims at providing performance guarantees to individual flows in access networks. We propose a new envelope process called Fractional Bounded Arrival Process for selfsimilar multimedia traffic representation. The policing of such a kind of traffic by using the leaky bucket algorithm is also proposed. We present a novel discipline for scheduling the upstream flows in EPON networks. In such a discipline, which is calle4 Proportional Sharing with Load Reservation, each flow is guaranteed a minimum share of bandwidth and the unused bandwidth is fairly distributed among them in proportion to their own demands and priorities. We analyze the performance of the proposed discipline and provide fairness and delay bounds on a per-flow basis
