Why the RIS?
•Many tools that debug Internet
connectivity, e.g. Ping, TraceRoute, Protocol Analyzers, Router
debug commands e.t.c.
•Major drawback – No ‘history’. Only works with the current
status and configuration
•Another drawback – No perspective
‘mobility’ (exception: Looking Glasses, however, not all are
available to the public and they only provide information about the
AS where it’s installed)
