sandwichprobe: Internet packet probes data
Description
These data correspond to an experiment conducted by Coates et al. to
measure the difference in delay experienced by packet probes sent over
the Internet during a short period in 2001, from a desktop computer in
the ECE department at Rice University to similar machines at ten other
university locations. The data were intended for use with a newly
proposed method of Internet topology inference.
Format
The data is provided in two files. delaydata
is a three-column
data frame. The first columnf is the difference in delay of the small
packets (in milliseconds). The second column is the numeric code of
the destination of small packets. The third column is the numeric code
of the destination of large packet. host.locs
contains the character code of the destinations:
- IST Instituto Superior Tecnico (Portugal)
- IT Instituto de Telecomunicacoes (Portugal)
- Bkly University of California, Berkeley
- MSU1 Michigan State University (Host 1)
- MSU2 Michigan State University (Host 2)
- UIUC University of Illinois, Urbana-Champaign
- UWisc1 University of Wisconsin, Madison (Host 1)
- UWisc2 University of Wisconsin, Madison (Host 2)
- RiceU1 Rice University (Host 1)
- RiceU2 Rice University (Host 2)
