Modeling Open Optical Line Systems with GNpy

Time 10/18/18 10:40AM-11:00AM

Room Pacifica Ballroom 10/11/12

Session Abstract

Modern optical networks, built from coherent optical transponders, high-degree ROADMs and flexible optical components, can effectively separate the analog line system from the services layer. This disaggregation allows network operators to make the best choices from available technology and will lengthen the service life of their infrastructure. It also opens new opportunities for collaboration, resource exchange and research. But we will need new software tools in order to step away from the proprietary model that has dominated the optical networking world. Open control and monitoring APIs are a necessary first step, already available from many vendors. To predict the behavior of the line system we require simulation tools that understand the components and their interconnections. The Telecom Infra Project, through its Open Optical Packet Line group has written GNpy, a Python library that predicts OSNR between network endpoints using mathematical modeling of the fiber, amplifiers and ROADMs. This talk will present the GNpy tool, discuss its development and potential applications, and show examples of how it can be used in real networks.
