Abstract
Ethernet passive optical networks (EPONs) have emerged as a promising solution for the next generation access networks. As this technology matures, intensive research work is underway to enhance its functional capability and economic viability. This work evaluates the performance of EPONs from the analytical perspective. Specifically, this study elaborates an analytical framework to explore the performance characteristic of EPONs with quasi-leaved polling operation and gated resource allocation policy. By investigating the temporal relationship of multiple events successively occurred in such a system, a graphical presentation is developed to facilitate more quantitative analysis. Using classical queuing theory, we then derive closedform expression for the average packet queuing delay and average queue length of the researched EPON model. Simulation experiments show that the derived analytical expression can precisely evaluate the network performance for memoryless traffic inputs, as well as to closely estimate the performance of lightly loaded network for bursty input traffic profiles.
