To see the difference between traceroute and rtt's for multiple days , we developed traceroute archive. It can be accessed using traceroutearchive.cgi script. It displays traceroute from a monitor node to the monitoring node for any three days (which can be selected from drop down menu). It checks loops within traceroute and shows the changes observed in a link for the requested days. It is currently available from SLAC to world wide nodes monitored by SLAC at http://www-wanmon.slac.stanford.edu/cgi-wrap/traceroutearchive.cgi and also from pingER Seecs to all monitored sites within Pakistan at http://pinger.seecs.edu.pk/cgi-bin/traceroutearchive.cgi
Traceroute Archive Flow At SLAC
Following are scripts used for traceroute archive
?1. Collection of Traceroutes
