The University of Michigan and Merit Network, Inc. are pleased to announce the 1.0 Beta release of ASExplorer. The new ASExplorer is the first of a series of visualization tools being developed by the Internet Performance Measurement and Analysis project (IPMA). Please see: http://www.merit.edu/ipma/asexplorer The new, light-weight ASExplorer Java client displays routing instability data received from one or more user-selected channels. We are currently providing channels for routing instability data collected at the AADS, MAE-East, MAE-West, PacBell, and PAIX exchange points. Some of the new features of ASExplorer include: * Who is AS1239? Well, just float your mouse cursor over AS1239, and we'll tell you! Dynamically updated Internic information tells you more than just an AS number -- try it and see. * Instability levels are monitored via graphs of BGP announcements and withdrawals, both updated in real-time. * Lists of currently flapping prefixes are hooked into the main ASExplorer window, and allow you to jump to an AS with a single click. * ASExplorer now lists all of the announced routes by an AS within the last time window (currently fixed at 75 minutes). * You can jump directly to an AS if you know its AS number. No more hunting through layers of HTML. * Can't figure out how the darn tool works? Use the on-line help! Also note that if you just want to look at the real-time graphs, you can view them at http://www.merit.edu/ipma/realtime/. The new version of ASExplorer relies on the Salamander Data Distribution infastructure to provide real-time updates to the client applets/application via a platform-independent webcasting technology. If you have any questions, comments, or any form of criticism, please feel free to send mail to ipma-support@merit.edu. P.S. If you have any problems running the ASExplorer software, please mail us the contents of your Java console and a brief description of your problem. The ASExplorer team will be more than willing to help you get the software up and running. - Jimmy vecna@eecs.umich.edu
