EstherLerouzic 56e615c713 Feat: Use a reference channel per OMS instead of total power for design
Correctly uses the oms band and spacing for computing the nb of channel
and total power for design per band.
In order to keep the SI values as reference, introduce a new parameter
in SI to indicate wether to use this feature or not.

If "use_si_channel_count_for_design": true, then the f_min, f_max and spacing
from SI are used for all OMSes
else, the f_min, f_max, spacing defined per OMS (design_bands) is used.

This impacts tests where the artificial C-band boudaries were hardcoded, and
it also has an impact on performances when SI's defined nb of channels is larger
than the one defined per OMS. In this case the design was considering a larger
total power than the one finally propagated which resulted in reduced performance.
This feature now corrects this case (if "use_si_channel_count_for_design": false
which is the default setting). Overall autodesign are thus improved.

GNPy: Optical Route Planning and DWDM Network Optimization

Install via pip Python versions Documentation status GitHub Workflow Status Gerrit Contributors Code Coverage via codecov DOI Matrix chat

GNPy is an open-source, community-developed library for building route planning and optimization tools in real-world mesh optical networks. We are a consortium of operators, vendors, and academic researchers sponsored via the Telecom Infra Project's OOPT/PSE working group. Together, we are building this tool for rapid development of production-grade route planning tools which is easily extensible to include custom network elements and performant to the scale of real-world mesh optical networks.

Quick Start

Install either via Docker, or as a Python package. Read our documentation, learn from the demos, and get in touch with us.

This example demonstrates how GNPy can be used to check the expected SNR at the end of the line by varying the channel input power:

Running a simple simulation example

GNPy can do much more, including acting as a Path Computation Engine, tracking bandwidth requests, or advising the SDN controller about a best possible path through a large DWDM network. Learn more about this in the documentation, or give it a try online at gnpy.app:
