Hi The NSF net topology is, I think, represented in this diagram: https://github.com/knowledgedefinednetworking/NetworkModelingDatasets/blob/… 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/un… 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/rout… [{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?
