TTM daily processing

analyze-rvec

The analyze-rvec script coordinates the processing of the RVEC files with the results from the traceroutes measurements performed by the remote boxes. It calls the analyze program with the proper list of files to process.

Both the database and the analyze program will be reimplemented soon. Requirements have been submitted to the Software Department.

Note that TTM analysis has the requirement that the traceroute DB has been updated before the test packet measurement data are processed: as long as we add vector id and number of hops to the delay datastructure, the routes must have bene processed first, in order to do a proper matching.

Occasionally, it could happen that transfer of a RVEC file fails, while transfer of a SNDP (send data) file succeeds. All send packets will then either be matched to the wrong (previous day's) routing vectors or not have any routing vector assigned at all. Therefore, if transfer of RVEC file succeeds the next day, all data send by the box will have to be reprocessed to correct the route vector matching.
