Notes on the Peering Matrix

  • bilat: 0, multilat: 2352
  • Clicking the AS number in the table header will isolate that column. Clicking individual cells in the body will freeze the dynamic highlighting.
  • Where a INEX member is not listed on this peering matrix, it is because they are currently not actively peering at INEX, or because they have opted out of presenting their peering information in this database.
  • This peering matrix is based on sflow traffic accounting data from the INEX peering LANs and route server BGP peerings.
  • This peering matrix only detects if there is bidirectional TCP flow between routers at INEX. It cannot detect whether there are actually prefixes swapped between routers.
