Abstract
We study the upgrading problem of existing Passive
Optical Networks (PONs) that need to increase their capacity at
different points in time. Our method upgrades line rates and migrates
network services over new wavelength channels based on
increasing traffic demand and cost constraints. Our method minimizes
capital expenses and system disruptions, while ensuring effective
resource usage. Our multistep model uses Mixed Integer
Linear Program (MILP) formulations whose cost parameters are
set by a pricing policy. We evaluate the PON upgrade through installation
of single-wavelength transceivers or multiple-wavelength
arrays of transceivers. We consider a typical case study, which is
solved using CPLEX. Illustrative examples demonstrate the attractive
properties of our method.
