PCH

Daily Routing Snapshots

PCH operates route collectors at more than 100 Internet Exchange Points around the world. Data from these route collectors is made available publicly for the benefit of the Internet's operational and research communities. PCH maintains two different, but complementary, kinds of data from these route collectors.

  1. Daily snapshots of the results of "show ip bgp" on PCH route collectors These indicate the state of the routing table on PCH route collectors at the moment in time that the snapshot is taken. Note that the state of the routing table will change from moment to moment across the course of a day as a route collector receives new routing announcements from peers. These are available below.
  2. Archives of MRT format files with BGP updates These provide the raw stream of BGP updates received by PCH route collectors. While the "show ip bgp" data provides a daily overview of each route collector's routing table, these archives of BGP updates provide information on the changes in routing data received from PCH peers which contribute to moment to moment changes in a route collector's routing table. These are available here.

Note that the data collected by PCH represents the sum of inter-domain routing announcements received from PCH peers. This data does not, and cannot, reflect the status of every autonomous system at an IXP.

Note - Some route-collectors in this data set were renamed at different points. This file provides a mapping of previously used names to their current equivalents:
