Re: BGP community attribute taxonomy
- From: Benoit Donnet
- Date: Tue Dec 04 04:56:19 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

Dear Nanog community,
During the past years, we have seen an increasing usage of the BGP
community attribute. For instance, in a recent BGP table dump from
routeviews, 99% of the routes stored by the router carries BGP
communities.
In this context, we are currently working on a BGP community
taxonomy, i.e., we want to classify and document communities
according to their usage. We describe our taxonomy on the
following url: http://inl.info.ucl.ac.be/communities
Based on this taxonomy, we tried to collect as much as possible
information on BGP communities. This was a daunting task as we
mainly relied on public database, such as whois server and ISP web
sites.
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.
Best regards.
Dr. Benoit Donnet & Prof. Olivier Bonaventure
