This will typically be the traceroute.pl web-based traceroute/ping tool developed by SLAC. Others may be added should we find a set of accessible ping MAs MAs that we can access to request pings to a target.
...
We will maintain a database of router locations. To populate this we will identify representative targets in regions of the world and carriers, and make regular traceroutes from the MAs to the targets and use the geolocation to locate the unknown positions of the routers at each hop. Having a database of router locations will mean the interactively locating the routes in a traceroute will be much faster and interactive. If the router location are not in the database when a user requests a visual traceroute then the results will be added to the database.
To assist in populating this database, we will also develop a tool to provide a traceroute archive. The traceroutes will be made from a MA at Stanford in the US and a second in Pakistan in Islamabad. The measurements will be made regularly (initially daily) and database. The masurements, will be accessible via the web, together with an analysis and comparison of the tracreroutes for 3 selected days (by default the most recent three days).
