A Segmentation and Design Method for Large-Scale Optical Path Networks based on Traffic Distribution Information

Abstract (in Japanese) (See Japanese page) 
(in English) We propose a segmentation and design method for large-scale optical networks considering traffic distribution.
For networks of several hundred nodes,it is required to regenerate optical signals at regular intervals by costly 3R regenerators and reduce expensive operation, administration and maintenance cost.
We have already resolved these problems in regular mesh networks with uniform traffic distributions by splitting them into several sub-networks called segments where all regeneration and wavelength conversion functions are placed on the boundary nodes [Sugimura et.al.~'05].
As a generalization to general topologies with nonuniform traffic distributions, the proposed method divides given network, that is assumed to be equivalent to a 2-connected indirected plane graph, into minimum cycles.
Then it iteratively merges the cycles to segments while maximum distance between any node pair in each segment is smaller than specified transmissible distance of optical signals.
The cycles to be merged are selected so as to minimize total traffic volume acrossing segment boundaries that can be estimated by using traffic distribution information.
