There are no works in which the end-to-end performance from end-users of the access network to metro networks is evaluated. In this study, we aim to obtain trace files of incoming traffic at the entrance of Optical Line Terminal (OLT) by running simulations of an EPON network implementing Interleaved Polling with Adaptive Cycle Time (IPACT)'a well known resource allocation scheme. Then, the generated traffic pattern will be characterized in order to find corresponding traffic model among well known traffic models and this model will be used as access traffic to the OLT
