-----BEGIN PGP SIGNED MESSAGE----- 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: http://www.ris.ripe.net/bgplay/ 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. Links to Respective Groups: * RIPE NCC Routing Information Service: http://www.ripe.net/ris/ * Roma Tre Computer Networks research Group: http://www.dia.uniroma3.it/~compunet/ Please note that BGPlay requires the Java browser plug-in version 1.4 or above (you can download it at http://www.java.com/en/download/ if you don't have it). If you have the Java plug-in installed, click on one of the links below for examples of BGPlay in action: 1.
