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.

Vince Fuller has done some projections on what the the routing tables willbe 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. Regards Bradley Freeman 2008/9/1 Moazzam Khan <emoazzam () gmail com>Thanks Stefan for your reply.Basically the goal of this testing is to study the BGP scalability issuesinthe 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 simulationenvironment.Can you suggest how I can set up the envrionment for this kind of study andwhat parameters should I try to caputre.

In my experience, eBGP testing is fairlystraightforward as you are almost always testing reconvergence of the BGPnext-hop.iBGP testing scenarios on the other hand can be quite a bit more complexasyou may also be testing the reconvergence of the underlying IGP if theBGPnext-hop remains unchanged. Can you describe your testing goals and environment in a bit more detail?

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 youguys. Regards MAK
