OWAMP 3.0c Released
This version of the draft implementation code, which adheres to IETF RFC 4656, includes many changes to the man pages. The new (-N) option to the three client applications (owping, owstats, and owfetch) allows users to sub-set a data file to produce statistics over smaller sample sizes than a complete owp file.

This version also addresses a minor bug in the powstream application (output summary files were not being flushed to disk until just after the file name was printed to stdout). The order has been changed, so any application that might be reading those filenames can now rely on the fact that the summary files are complete at the time the filename is seen. The new release of the code can be found at: http://e2epi.internet2.edu/owamp/download/owamp-3.0c.tar.gz.

Network Performance Workshop in Honolulu
Internet2 offered a 1.5 -day hands-on workshop focusing on performance testing and continuous measurement before the recent Joint Techs Workshop in Honolulu . Participants received training on how to use the open source measurement tools used by Internet2 and ESnet to solve particular problems, including locating duplex mismatch, congested links, and faulty equipment, among others.
