Abstract

We propose an adaptive wavelength allocation pattern for scheduling multi-wavelength ONUs in the NG-EPON. Proposed wavelength allocation patterns make online decisions for ONU wavelength allocation based on an adaptive threshold that reflects both ONU’s absolute bandwidth request size as well as the relative bandwidth request size to other ONUs. The proposed wavelength allocation pattern has low complexity and good network performance. Simulation results show that the proposed wavelength allocation pattern achieves small packet delay, huge bandwidth throughput, and a low packet loss ratio in different network conditions, which outperforms the existing wavelength allocation patterns for the NG-EPON.
