TULIP - Raja
We have sent a reminder email to Yahoo giving them an update on TULIP and how it might be extended to meet their needs. They have responded, they appear to be interested. We are trying to interest them in providing landmarks.
Raja uses the options feature of traceroute.pl to reduce the time for the PingER/perfSONAR landmarks to make the pings by a factor of 5. Given this we probably need to review the timeouts. Also we are now using caching and nightlty we populate the caches by a cronjob tracerouting to the PingER targets from SLAC, CERN, NUST, ICTP, UM and ICTP. This also helps speed things up. We added wildcards and comments to the caching.

cgi-wrap/reflector.cgi?function=vtrace It is a visual traceroute. It uses TULIP to locate the routers. t is in beta test and needs testing by friendly users. We are looking to ada a link to it from the perfSONAR home page.

Raja has also re-written the historical traceroute facility that takes nightly traceroutes and allows one to retrieve and compare them. He then extended it to use the reverse traceroute facility to provide histories for NUST, CERN, UM as well as SLAC. When the UNIMAS and UTM traceroutes work, we can include them. See for example http://www-wanmon.slac.stanford.edu/cgi-wrap/traceroutearchive.cgi
