Distributed online RWA considering add/drop contention in the nodes for directionless and colorless ROADMs


This paper presents an online distributed RWA algorithm that considers the add/drop ports occupation in directionless-colorless ROADMs, to reduce the lightpath blocking. Results support our approach to reduce the number of ROADM transponder banks.
