Announcing BGPlay - A Tool Hosted By the RIPE NCC that Visualises BGP Updates

Hash: SHA1

Dear All,

The Roma Tre University Computer Networks Research Group and the RIPE
NCC are pleased to announce BGPlay, a new beta tool that can
visualise BGP updates in the Routing Information Service's (RIS)
database. Its animated, interactive graphical display makes it easier
to interpret how BGP updates affect the routing of a specific prefix
than by analysing the updates themselves. For an idea of what BGPlay
can do, please visit the BGPlay web page at:

and click on the screenshot for an interactive help page.

BGPlay was developed by the Computer Networks Research Group at Roma
Tre University, and is hosted by the RIPE NCC, who provide direct
access to the RIS database.
