[Kdn-users] GBN topology

Hi On this page: https://github.com/knowledgedefinednetworking/Unveiling-the-potential-of-GN… I have seen that there is this data set: http://knowledgedefinednetworking.org/data/GBN.zip It is described as having been used for evaluation, but I can’t find anything else that refers to it. Can anyone tell me more please? Many thanks Nathan
