ANNOUNCEMENT: BGPlay @RIS upgraded to 1.4
by Lorenzo Colitti 30 Nov '04

30 Nov '04

[Apologies for duplicate emails] Dear All, The BGPlay team is pleased to announce that the BGPlay instance hosted by the RIPE NCC has been updated to BGPlay v1.4. Notable fixes in this release include: - Depending on the exact query interval input by the user and the sequence of BGP updates preceding it, previous versions of BGPlay sometimes generated an incorrect initial AS graph. This has been corrected. - If the query interval was spread over multiple days, BGPlay would sometimes not display all BGP updates on the last day. - BGPlay no longer crashes when it encounters an AS-set. - Mouse wheel scrolling has been much improved: the animation window no longer scrolls one pixel at a time. - Better error handling and reporting BGPlay is a tool to visualise BGP updates in the Routing Information Service (RIS) database. An animated, interactive graphical display makes it easier to interpret how BGP updates affect the routing of a specific prefix. For an idea of what BGPlay can do, please visit the BGPlay web page at: http://www.ris.ripe.net/bgplay/ Click on the screenshot for interactive help. Please note that BGPlay requires the Java browser plug-in version 1.4 or above (this is available for download at http://www.java.com/en/download/ ). 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 send any comments to <bgplay(a)dia.uniroma3.it> and <ris(a)ripe.net>. On behalf of the BGPlay team, Lorenzo Colitti
