Re: transportPCE and gnpy

Hi Michael

I agree the documentation at
does not answer these questions.

Until recently, GNPy had no standard REST interface so we had to start from scratch when developing a REST interface for transportPCE.

It was a long time ago. GNPy made recently some progress to propose a standard REST interface.
And we are now converging to something much more stable though it is still a bit fluctuating.
I think it is still under work but I might be wrong.
Ahmed or Olivier in CC are following that much closer than me and might tell you more about it .

more details at

You can find an example on how to use our GNPy REST interface in tests/transportpce_tests/pce/
It has been automated in the CI recently.

You can run it via tox with python 3.8 with the following command.
$ tox -e buildcontroller,testsPCE gnpy

Python 3.9 and > work too but you have to unforce the version specified in tox.ini

NB: Older versions requiring a docker image were not automatically evaluated by the CI and were tested manually.

Let me know if you have any issue to make it work or to infer how to deploy a working solution from it.

Hope this helps

Objet : [ODL Discuss] transportPCE and gnpy


we try to find out how gnpy and transportpce are working together, since we found some commits and presentations with this. My question is:

Is there a documentation how to get this working together? Something like
  * a deployment documentation,
  * a README with the steps to configure transportPCE and gnpy,
  * or any other documentation.

Sadly I was not able to find any articles in the odl wiki about it, but maybe I do oversee something.

Thanks in advance.

Kind regards,
