Linear Formulation to Avoid Adjacent Channel Interference in LTD of Optical Networks

摘要

A strategy is implemented for solving the Logical Topology Design (LTD) based on a Linear Formulation (LP) with channel interference constraints. The formulation is able to provide excellent solutions. In traditional LTD Problem there is no a-priori knowledge of channel use and once the solution has been implemented the interference cannot be avoided. Taking into consideration the effects of adjacent channel interference, we extend the traditional formulation as a set of analytical formulas as additional constraints on LTD.
