Line System Design for DWDM Networks

Overview

State-of-the-art Dense Wavelength Division Multiplexing (DWDM) allows data transport with very high capacity, measured in terabits per second, and very long reach, thousands of kilometers. One current DWDM technology arranges network elements into line systems, where a line system is a path consisting of alternating network elements and optical fibers. A line system is a linear sequence of network elements (OADMs) and fibers, all optically transparent. This paper describes algorithms for partitioning a DWDM mesh network into line systems, given a demand matrix.
