Dear Nathan,

We have observed some inconsistencies between the node IDs in the PNG figure of NSFNet and the IDs used in the NED file. We have modified the PNG figure (https://github.com/knowledgedefinednetworking/NetworkModelingDatasets/blob/m...) to make it match with the NED file.

We also checked that the node IDs in the rest of topologies already matched with their corresponding NED files.

Thanks,

José Suárez-Varela

Hi

The NSF net topology is, I think, represented in this diagram:

https://github.com/knowledgedefinednetworking/NetworkModelingDatasets/blob/m...

The same network is also, I think, represented by the NED file in this compressed tar:

http://knowledgedefinednetworking.org/data/datasets_v0/nsfnet.tar.gz

That NED file is also here in my project:

https://github.com/Data-Science-Projects/demo-routenet/blob/master/tests/uni...

In that NED file, I see these connections:

node2.port[2] <--> Channel10kbps <--> node5.port[0]; node4.port[1] <--> Channel40kbps <--> node5.port[1]; node5.port[2] <--> Channel10kbps <--> node12.port[0]; node5.port[3] <--> Channel10kbps <--> node13.port[0];

In my (refactored from original code) I have these values for the connections at https://github.com/Data-Science-Projects/demo-routenet/blob/master/src/route...

[{0: 1, 1: 3, 2: 2}, {0: 0, 1: 2, 2: 7}, {0: 0, 1: 1, 2: 5}, {0: 0, 1: 4, 2: 8}, {0: 3, 1: 5, 2: 6}, {0: 2, 1: 4, 2: 12, 3: 13}, {0: 4, 1: 7}, {0: 1, 1: 6, 2: 10}, {0: 3, 1: 9, 2: 11}, {0: 8, 1: 10, 2: 12}, {0: 7, 1: 9, 2: 11, 3: 13}, {0: 8, 1: 10, 2: 12}, {0: 5, 1: 9, 2: 11}, {0: 5, 1: 10}]

Node 5 is: {0: 2, 1: 4, 2: 12, 3: 13}, which means node 5 is connected to nodes 2, 4, 12 and 13. In the diagram, node 5 is connected to 2, 4, 12 and 8.

Does anyone have any ideas as to where the discrepancy is coming from please?

Many thanks
