[Outages] Link-Rank 1.0 alpha for visualizing BGP routing changes

[Mohit Lad]

Dear all,

Apologies if you have already received this. We recently released an  
alpha version of Link-Rank 1.0 tool.

Summary: Link-Rank works by weighing AS-AS links from each BGP router  
by the number of BGP routes carried, and visualizes routing events as  
changes in AS-AS link weights. Red edges represent loss of routes  
while green edges represent gain of routes. The tool can currently  
visualize data starting from January 1, 2007 from RouteViews' Oregon  
collector, with a time lag of 1-2 hours.

The tool can be downloaded from
http://sourceforge.net/projects/link-rank/
More information about the Link-Rank project can be found on the website
http://linkrank.cs.ucla.edu/

The new version has various improvements over existing version including

1. Better handling of very large routing events.
2. Ability to save and load graphs. Some sample events are included  
in the "Examples" directory.
3. Near real-time continuous visualization (This feature is being  
tested and will be available in the beta release soon).
4. Redesigned GUI based on feedback from previous release.

We expect to move to beta release in a few weeks and would really  
appreciate any bug reports or feature requests. The full source code  
of the tool will be available with the beta release. We will also be  
releasing a set of scripts and instructions to be able to use the  
tool with your own BGP data.
We hope you find this tool useful. Feel free to send us an email at

Thanks

Link-Rank team
