Fw: NCC#2006021124 [RIS Lease-A-Beacon Request]
Hi, I'd like to ask your view on this request. At the moment there are no available beacon prefixes that can be used for this experiment. So, we need to decide if we wish to support this user in his research and if so, we need to submit a request to RS for a new RIS beacon IP range. What do you think? I informed the user that we are discussing this case internally and will let them know when we have a solution (or not). Thanks, Vasco Asturiano -------------------------- Software Engineering Dept.

We propose an active measurement method to measure the impact of ASPP method under different prepending lengths and strategies. We applied it on a dual-homed, stub AS. We announce a prefix(/21) to both upstream ASes. But the announcement to one of the upstream AS, we applied different prepending length. After prepended once, we observe the route changes from different looking glasses (we have the script to collect the route changes from different looking glasses). However, we would like to perform the active measurement from other sites to see the effect.

I don't think we can currently do this automatically using the RRCs, so it would take a fair bit of manual tinkering to set it up initially. Maybe we could use the same setup that I used for the AS-set stuffing experiments, i.e. the BGP announcer and a cron job running on a machine with an IBGP peering to the RRCs.

Getting more prefixes should be trivial: walk to RS, ask them for a temporary assignment for an experiment).

That is more of a problem. If we can set this up easily, we should do this. If not, talk to Shane and see if he has the resources. In any case, we should reply to the original requestor "soon". Henk Henk

Actually, it would be really nice if Lorenzo will pick it up. I will not have time to do it for couple of weeks. Mailing thread is in xrtt. Ticket number is NCC#2006021124. Arife

Ok, so what these guys want to do is see how traffic shifts in different prepending configurations. They have already performed this using another AS (their own?) and they would like to do this from AS12654 as well. This is a reasonable research project, but implementing this on our side is more than a couple of hours of work. I don't really know much about RRC configuration file backups and the like, but it will probably take at least a day or two if we want to do it in any non-hackish manner. And of course whoever does it needs to have operational access to the RRCs. I can try to take care of this, but I'm not sure I'll have time to do this properly before the RIPE meeting.

Thanks Lorenzo for the reply. If Henk will have time tomorrow, shall we discuss it tomorrow? Even if we can not make it, it would be nice to tell them. Arife On Wed, Mar 08, 2006 at 03:46:58PM +0100, Lorenzo Colitti wrote:

Arife, Lorenzo,
If Henk will have time tomorrow, shall we discuss it tomorrow?
No, sorry, I won't. I'm flying back from Brisbane right now, my plan was to stop by the office for 2 hours at most tomorrow, just to say hi to Robert. I then have Thu pm and Friday off. Let's discuss this Monday. Can one of you schedule something? In the meantime, we should send them a "keep-alive" (sorry, we're really busy, we'll look at this next week). Henk
