Adaptive Grant Extension in OC-Enhanced PONs

We present a distributed mechanism termed Adaptive Grant Extension (AGE) for grant-size adjustment in Optical Coding (OC)-enhanced Passive Optical Networks (OC-PONs). AGE exploits the real-time queue updates of OC-PONs to allow the Optical Network Unit (ONU) to extend its transmission beyond the grant provided by the Optical Line Terminal (OLT), thus reducing average frame delay. We discuss the parameters and requirements of AGE in OC-enhanced Ethernet PONs (EPONs). Our simulations show delay gains reaching 9% over OC-PONs.
