Re: BGP Scalability Simulation

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.

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.
Regards
MAK
