Dear Nanog community,
We would like to thank you for helping us in our efforts on =20
documenting BGP communities.
As researchers, we are now in the process of writing a paper on our =20
work on BGP communities.
We plan to submit this paper to ACM SIGCOMM Computer Communication =20
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://=20
inl.info.ucl.ac.be/communities or directly at http://=20
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
