Multiclass systems with different Quality of Service (QoS) requirements are essential in nowadays Ethernet passive optical networks (EPON). In this paper, we propose a code division multiple access (CDMA) enabled dynamic power and bandwidth allocation (DPBA) algorithm for multiclass system. The novelty of the proposed algorithm is the resource allocation components: power control (PC) and bandwidth allocation (BA). Both resources are related and optimized through the weights of the Weighted Round Robin (WRR) scheduler in a way to meet both the physical layer signal to interference ratio (SIR) and the network layer packet delay (PD) requirements for every class of users. It is shown that the proposed algorithm can greatly enhance the network performance in terms of packet delay, throughput, and queue size management while guaranteeing the QoS requirements for all classes.
