thanks for your reply. That helps a lot.
One additional question. Since the commit Guillaume has linked is
relatively new, can I use the Opendaylight phosphorus-SR1 release
version or do I have to create it from the master branch? And am I
correct that your version (gnpy4tpce) which is 2.4.3 is then using
I think that Guillaume has well explained how the functional
test of gnpy-TPCE could be performed, which could be a good
first step to discover the tool.
Then, if you want to use the interface with other examples, you
can follow these steps:
1- install the gnpy with this command: pip install gnpy4tpce
2- Launch gnpy using this command: gnpy-rest
3- launch karaf for T-PCE
Now the two programs are ready to communicate and T-PCE will
take into account GNPy to check the feasiblity of the path.

I agree the documentation at https://docs.opendaylight.org/projects/transportpce/en/stable-phosphorus/developer-guide.html#gnpy-interface
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 https://git.opendaylight.org/gerrit/c/transportpce/+/99937
You can find an example on how to use our GNPy
REST interface in
It has been automated in the CI recently.
You can run it via tox with python 3.8 with the following
$ 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
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
* 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.
