Abstract

In this article, new Dynamic Bandwidth Allocation (DBA) algorithms which give high priority to some ONUs corresponding to important agencies are studied in order to manage emergency cases causing severe network traffic. In order to deal with such cases, the network state is divided into two states, namely the normal and the emergency states. We apply the Weighted Round Robin (WRR)-based algorithm to the normal state, and three priority-based DBA algorithms are applied to the emergency state. These algorithms are different from each other according to the mode of protecting non-priority ONUs from starving. Each algorithm is analyzed in terms of utilization of the uplink bandwidth and the average packet delay. Simulation and theoretical results show that the proposed algorithms are working properly at the emergency state and can satisfy more stringent QoS requirements than WRR algorithms.
