Hello Max, Thanks for your interest in our work.
Dear Benoit,
is there a list of communities and what it's mean?
The answer is yes. The list of communities we used in our work is freely available at the following URL: http://inl.info.ucl.ac.be/system/files/ CommunityTaxonomy-DataBase.xml_.gz This list is documented following our taxonomy. This is presented as an XML file. The next step in our work would be to propose to the community an on- line database that could be queried by anyone to get information on BGP communities. This database should also allow ISPs to document their own communities. Keep on Rockin' Benoit
For example, community 12530:51020 means say to Golden Telecom not to announce that prefix to C&W (see whois AS12530).
Some ISPs publish this info on RIPE DB (like AS12530), but is there a place for publish these communities?
Often it is very useful to make some ISP to accept certain way to your network, even if this ISP is in three-for hops from your upstream.

Dear RIPE Routing Working Group,
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 27,000 entries.
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'
