NPD-Routes

Description

These datasets contain Internet route measurements made using the traceroute utility. The measurements were repeatedly made between a set of Internet sites participating in the Network Probe Daemon (NPD) framework, described in the paper given below.

Format

Each measurement is the raw output from a single execution of traceroute. Different versions of traceroute ran at the different sites, so the format varies slightly. Rough awk scripts for parsing the files are available from the contributor. The filename of each measurement gives the name of the site originating the traceroute, the site to which the traceroute was attempted, and the measurement time in terms of Pacific Standard Time.

Measurement

The first dataset, NPD-Routes-1, consists of 6,991 attempted measurements made between 27 Internet sites, conducted from November 8, 1994, to December 24, 1994. Measurement failures appear in this dataset as empty files. The second dataset, NPD-Routes-2, consists of 37,097 attempted measurements made between 33 sites, 23 in common with NPD-Routes-1. These measurements were made from November 3, 1995, to December 21, 1995. Measurement failures in this dataset have been omitted, so there are 35,229 actual measurements present.

Privacy

The data is available directly as measured.
