Code for Understanding the Modeling of Computer Network Delays using Neural Networks

by Nathan Sowatskey

Hi The reference 18 in "Understanding the Modeling of Computer Network Delays using Neural Networks" points to the KDN site as the location of the code use: http://knowledgedefinednetworking.org I think that the section being referred to is labelled “Neural Nets:”, but I would like to confirm that please. Many thanks Nathan

Normalisation

by Nathan Sowatskey

Hi In the demo code, for example in: https://github.com/knowledgedefinednetworking/demo-routenet/blob/master/dem… A form of normalisation is applied: predictions = 0.54*preds + 0.37 This is consistent with the parse() function here: https://github.com/knowledgedefinednetworking/demo-routenet/blob/master/cod… if k == 'delay': features[k] = (features[k] - 0.37) / 0.54 if k == 'traffic': features[k] = (features[k] - 0.17) / 0.13 if k == 'link_capacity': features[k] = (features[k] - 25.0) / 40.0 There is another case here: https://github.com/knowledgedefinednetworking/network-modeling-GNN/blob/mas… if k == 'delay': features[k] = (tf.math.log(features[k]) + 1.78) / 0.93 if k == 'traffic': features[k] = (features[k] - 0.28) / 0.15 if k == 'jitter': features[k] = (features[k] - 1.5) / 1.5 if k == 'link_capacity': features[k] = (features[k] - 27.0) / 14.86 if k == 'queue_sizes': features[k] = (features[k] - 16.5) / 15.5 What is the basis for this normalisation and those specific constants please? Why does the normalisation in routenet_with_link_cap and routenet_with_forwarding_nodes differ? Many thanks Nathan

RouteNet with forwarding nodes

by Nathan Sowatskey

Hi I would like to know more about https://github.com/knowledgedefinednetworking/network-modeling-GNN/blob/mas… if possible please. The reference points to Proceedings of the 2019 ACM CoNEXT 2019 Student Workshop, Orlando, USA, December 2019. I have had a look here: https://conferences2.sigcomm.org/co-next/2019/#!/accepted-papers But I don’t see the paper. I can’t find it with a Google search either. Is there any other source for the paper please? Many thanks Nathan
