Conventions

We use the following conventions:

  • Country names are defined by the Mapland database since this is used to produce our maps and we cannot modify it.  Usually (but not always) it is in agreement with UN standards.
  • Regions are defined as given in the PingER NodeDetails Oracle database.

Deployment of Landmarks

There are about 60 SLAC/Looking Glass landmarks, and about 156 PlanetLabs landmarks.  We are working on filtering the latter to remove non- or poorly respodning landmarks. The PlanetLab landmarks send 10 pings very quickly, whereas the SLAC/Looking Glass landmarks send five 56 byte pings with one second between them, they will also wait for a deadline time of 30 seconds for pings to be replied to.
