COST 263 Common Measurement Infra-structure
|
|
Goal
|
To create a test-bed between partner sites for Voice Over IP
measurements. Scripts will periodically send telephony like
conversations between sites and the quality and reliability of the
links will be measured to assess the suitability of the Internet for
IP telephony.

Trace files
|
All files (currently 10355) are gnuzip compressed (winace 2.11 can
decompress this format on Windows). The directories indicate the
sender and the receiver, the filename is the GMT + 1. We used a
standardised time to easily detect bidirectional traces. We are
working on providing (renaming) traces with localtime filenames.
veloso Amhurst, Mass
obo02 Namur, Belgium
zorzal Buenos Aires, Argentina
topor Tampere, Finland
idmaps Ann Arbor, Michigan
rain Berkeley, California
local_host Stockolm, Sweden
login Lulea, Sweden
helena Berlin, Germany
The general format of the filename is:
.log_format
200202041808.log.gz
An alternative (newer) format that might be seen is:
yyyymmddhhmm_silenceSuppression_packetSize.log.gz
200202041808_0_20.log.gz for example. Where 0 indicates silence
supression and 1 means no silence supression. The packet size is in
milliseconds (packetisation so 20 means 160 bytes). Trace files can
be browsed here VoIP traces. They are can
be downloded as tarred gzip files for each connection.
