To begin with, we thank the community for their interest in ARDA 1.0 and their invaluable feedbacks while
using it. We are now committed to including private route collectors located in Africa as data sources,
as a next step for improving ARDA’s accuracy. We describe below the modalities for IXP operators to
contribute to this data collection process
1. Which types of private route-collectors are concerned?
Only private route-collectors located in Africa with a peering viewpoint (and not a global viewpoint)
are concerned by this approach. These include route-collectors deployed at an African IXP and at
which members announce solely their network as well as those of their customers (but not those of their
peers and/or transit providers).
2. How do we plan to collect these data?
An IXP operator interested in participating can first create an FTP or web repository destined
to host the daily dumps from the route-collector. He can then mail the corresponding url
as well as his details to email@example.com
. Note, the said url will be
kept private during the processing. He will be then be notified whether or not the repository
fits with the requirements listed in 3 and 4.
3. How to organize the repository?
In the created repository, each year will correspond to a folder whose name will be a number corresponding
to that of the year. Similarly, the names of its subfolders will vary between 01 and 12, depending on
the months in which they will be generated. Further, the name of a file contained in that repository will be under
the format Year_Month_IXPname.gz
. This way, ARDA will for instance
access a given file 2017_08_13.gz
through the url, Repository_url/2017/08/2017_08_13.gz
4. Which format to use for the files?
We suggest that the files of the repository contain the daily dumps of the route-collectors presented
under the show ip bgp
output of a Cisco or Quagga router. In order words, the routing information should
be presented in the order:
Network, Next Hop, Metric, LocPrf, Weight, Path
IXP operators using another type of router (Bird, Juniper, Huawei, etc.) can contact us at
for discussions, before we retain a common format.
