An automatic load-balancing DWBA algorithm considering long-time tuning devices for λ-tunable WDM/TDM-PON

We propose an automatic load-balancing DWBA algorithm for λ-tunable WDM/TDM-PONs. The algorithm is widely applicable despite the use of long-time tuning devices. We have confirmed with simulations that the proposed algorithm properly activates λ-tuning when the load-balancing is needed although the λ-tuning period is much longer than the DBA cycle.
