What do we think about this lease a beacon request? Henk

Hello Henk,
I am Hitesh, Paul's student working on the IP Anycast project (http://pias.gforge.cis.cornell.edu). As Paul mentioned to you, we are interested in doing some measurement studies on IP Anycast and think that the RIS beacon service offered by your group can serve as a very useful testbed for such measurements. We have acquired an AS number and a prefix (a /22) for this purpose and would like to use some or all of your RRCs as anycast servers by advertising our prefix through them. I can see two ways in which this can be done:
* If it is possible for me to get access to the beacon boxes, I could run a software router on them to peer with your beacon software and advertise our prefix through your AS. Note that we would like our own peering, instead of the beacon service being currently offered, so that starting and stopping of the advertisements and the RRCs being used can be controlled by us. Apart from the software router, I will also need permissions to run a DNS server on the same host.
* In case access to the beacon boxes is not possible, we could establish EBGP peerings between a box here at Cornell and your RRCs over tunnels. In effect, this would allow me to run whatever I need on my boxes while you would only need to support a BGP peering across a tunnel (and advertise our prefix onwards).
In any event, if either of these options seem feasible, I would be more than happy to provide more details about the kind of experiments we want to run, the peering requirements, the amount of traffic that can be expected and so on.
Thanks. -- hitesh

This doesn't seem like a great idea. I doubt that our agreements with our peers cover announcing prefixes that do not belong to the RIS, providing transit to other ASes, and forwarding traffic. Also, the prepending work with HK university has shown me that many of our transit peers filter on ^12654$, i.e. don't even accept prepending of our own AS. If they want to do this, since they already have an AS and a prefix, why don't they get someone to give them transit for the duration of the experiment?

I do agree with Lorenzo, implementing such a thing will put us in difficult situation with our peers. It would be difficult to explain somebody's AS.

Probably a better solution for them.

I agree, I'll write this to them. Henk At 09:57 04/09/2006, Arife Vural wrote:
