Multi-period planning in metro-aggregation networks exploiting point-to-multipoint coherent transceivers

Abstract

This paper proposes an integer linear programming framework to optimize the multi-period planning of metro-aggregation networks exploiting point-to-multipoint coherent pluggable transceivers and a filterless line system architecture. We investigate several planning strategies to minimize capital expenditure caused by transceiver cost based on the predictability horizon of traffic and availability of transceivers during planning while considering operational expenses (OpEx) as well. The results obtained by evaluating a deployed reference network provide evidence of reductions in transceiver cost between 20% and 32% compared to that in the point-to-point approach, and the OpEx can be reduced by around 30% at the expense of a 10% increase in transceiver cost over a five-year planning period.
