Efficient resource management via dynamic bandwidth sharing in a WDM-PON ring-based architecture

In this work, we propose an efficient resource management approach for WDM-PON ring architectures that supports dynamic bandwidth allocation and sharing of downstream wavelengths. We propose a modification in the ONU design, to dynamically setup virtual circuits for inter-ONU communication. The reservation mechanism is arbitrated by the OLT, which also monitors the traffic imbalances of downstream channels.
