A fair and flexible dynamic wavelength and bandwidth allocation algorithm for IEEE 100G-EPON

In the IEEE 100G-EPON, channel bonding enables ONUs to work on multiple wavelengths simultaneously to achieve higher peak rates. Three types of ONUs (25G, 50G and100G ONUs) share all the 100G bandwidth and each type of ONUs have a total capacity constraint. In this paper, a fair and flexible dynamic wavelength and bandwidth allocation algorithm is proposed for 100G-EPON. Proposed algorithm considers weighted fair as well as capacity constraints for each type of ONUs. Simulation results show that ONUs share bandwidth fairly based on their weights. Besides, overloaded ONUs can flexibly share the bandwidth within capacity constraints.
