We have a similar analysis (which agrees with Vince Fuller's #s in a general sense) in the middle of a recent sigcomm paper: http://www.aip-arch.net/ See the paper "Accountable Internet Protocol (AIP)". I point it out mostly because the Fuller presentation said "kinda looks exponential"; we found that the scaling was 17% per year, which could be a bit more useful if you need to come up with #s for the years between when Fuller provides projections for. -Dave On Sep 2, 2008, at 8:41 AM, Brad Freeman wrote:
Vince Fuller has done some projections on what the the routing tables will be like in the near future which would be useful for you, check out http://www.ripe.net/ripe/meetings/ripe-53/presentations/rou-vf-sca.pdf
If you are looking at doing simulations of what it could be like, use similar figures to his for IPv4 & IPv6 routing table size.

Thanks Stefan for your reply.
Basically the goal of this testing is to study the BGP scalability issues in the internet sometime in future lets say 10 years from now and try to find out what problems it could face . I am trying to use ns2 as my simulation environment.
Can you suggest how I can set up the envrionment for this kind of study and what parameters should I try to caputre.

Topology and setup of these kinds of tests largely depend on whether you are testing iBGP or eBGP. In my experience, eBGP testing is fairly straight forward as you are almost always testing reconvergence of the BGP next-hop. iBGP testing scenarios on the other hand can be quite a bit more complex as you may also be testing the reconvergence of the underlying IGP if the BGP next-hop remains unchanged. Can you describe your testing goals and environment in a bit more detail?

Hi
I am trying to simulate BGP for scalability testing. I have few queries.
1) What sort of topology I should try out ?
2) What parameters should I test?
I am trying to simulate it in ns-2 and i would appreciate reply from you guys.
