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
> contains more than 12,000 entries.
>
> When running our database and taxonomy on recent BGP table dumps
> from RouteViews and RIPE (last dump from September 2007), we were
> only able to classify, on average, 20% of the encountered communities.
>
> Based on this result, we ranked the unclassified BGP communities.
> Here is the top 10 of most seen ASes using uncommented communities:
> AS19151
> AS3549
> AS3549
> AS2914
> AS7473
> AS286
> AS3292
> AS13237
> AS6667
> AS34225
>
> You can find the top 100 on the following url: http://
> www.info.ucl.ac.be/~donnet/communities.html It gives the AS number
> as well as, for each AS, the various unclassified communities and
> their total frequency (i.e., the number of times the AS with
> unrecognized communities is encountered in table dumps).
>
> If you have any documentation regarding these communities, it would
> be very helpful if you can send us back this information. The
> easiest way for you is probably to reply to this email and attach
> the information (text, PDF, doc file, ...).
>
> When our database will be enough representative of the used BGP
> communities, we will made it freely available. We will also
> propose a way for updating (adding or removing) BGP communities
> information in our database.

> Thanks in advance.
