Dear Nathan,
Probably you read our work-in-progress version uploaded at ArXiv.
Please, check the last version published in the proceedings of ACM SOSR
(https://dl.acm.org/citation.cfm?id=3314357). Here, we make the
evaluation also in GBN.
Sorry for the possible misunderstanding. We uploaded the README page
(https://github.com/knowledgedefinednetworking/Unveiling-the-potential-of-GN…)
to provide the link to ACM SOSR.
Regarding the GBN topology, unfortunately we didn't prepare a figure.
However, you can find an image of this topology at the following paper
(Figure 4):
J. Pedro, J. Santos, and J. Pires, “Performance evaluation of integrated
otn/dwdm networks with single-stage multiplexing of optical channel data
units,” in Proceedings of ICTON, 2011, pp. 1–4.
I hope it will be useful.
Regards,
José

Thank you Jose. I have read the paper (many times
:-)). I have seen the details of the evaluation with the Geant2 network, but there is no
mention of the GBN network in the paper.
I am perfectly comfortable with processing the data (you can see my code here:
https://github.com/Data-Science-Projects/demo-routenet).
Specifically for the GBN network, I wanted to see what the topology looks like. I have
the NED file, but I can’t use that NED file with OMNet (for reasons discussed elsewhere).
I can, of course, manually reverse engineer the NED file. But I wanted to ask if there
was already a topology diagram just to save me the effort.
Regards
Nathan

generalization capability of the model.
