Description ASExplorer is ideal for diagnosing inter-domain routing problems on ISP backbones. ASExplorer uses the Salamander data distribution system to provide updated information via a real-time push webcasting system. Users simply launch the Java applet, click on an AS, and follow the links to display the number of announcements made by successive layers of neighbor ASs. Once you launch the Java applet, it may take a minute or so for the new window to appear on your screen. Orange indicates over 16 announcements, and so on.
Users can easily change the color coding to use any system preferred.
Similarly, the user can change the value at which ASExplorer will filter out data. For example, by default, only AS's that make more than 4 BGP announcements will be displayed. By choosing 'Show Graph of Current Instability Levels', you can display instability graphs that are constantly updated in real-time. The graph plots the aggregate number of BGP announcements and withdraws in 15 minute intervals seen at the Route Servers today. Table of Current Flapping Prefixes By Choosing 'Show Current Flapping Prefixes' under 'Show Data', you can view a table detailing the number of BGP announcements and withdrawals recieved from each Route Server peer during the last fifteen minutes.
