BGP community attribute taxonomy

Tue Dec 4 09:54:04 UTC 2007

Dear Nanog community,

We would like to thank you for helping us in our efforts on  
documenting BGP communities.

As researchers, we are now in the process of writing a paper on our  
work on BGP communities.

We plan to submit this paper to ACM SIGCOMM Computer Communication  
Review for the April issue.  This is an editorial paper (max. 4 pages).

You can find a preprint of the paper at the following URL: http:// 
inl.info.ucl.ac.be/communities or directly at  http:// 
inl.info.ucl.ac.be/system/files/communities.pdf

Any comments on the paper is welcome.

Thank you very much.

Keep on Rockin'

Benoit & Olivier

> Our current database of classified BGP communities currently

> Here is the top 10 of most seen ASes using uncommented communities:
> AS19151
> AS3549
> AS3549
> AS2914
> AS7473
> AS286
> AS3292
> AS13237
> AS6667
> AS34225
