N2 - This paper presents a method for constructing logical topology in multi-hop WDM networks hierarchically. Our logical topology can be built over WDM ring networks with only three ADMs (Add-Drop Multiplexers) and transceivers per node. We aim to realize low-cost WDMs that can be deployed for MANs and LANs. Due to well constructed hierarchical topology, both the maximum distance between two nodes and the number of required wavelengths on each optical fiber are reduced to the logarithmic order of the number of nodes. This contributes to mitigate traffic costs in WDM networks. Furthermore, we propose a node labeling scheme to achieve efficient routing without routing table lookup. From our numerical experiments, we have shown that we could construct a logical topology consisting of 1,000 nodes with a very small diameter and 16 wavelengths in a WDM ring network.
