Optical in-band crosstalk monitor placement using Partial Set Cover model

Abstract

In this paper, switch induced in-band crosstalk impairment is used for evaluating the number of monitoring devices with respect to the amount of reported monitoring information in items of optical signal to crosstalk ratio. Partial Set Cover model and greedy algorithm with four heuristic parameters are proposed for placing the monitor devices for performance evaluation. The numerical results showed that heuristic parameters, Interference Rate (IR) and Highest Crosstalk Analytical Value which are computed during network operation, outperform parameters, highest degree and lowest degree which are determined at network planning stage in NSF, GRID and Mesh topologies.
