Re: BGP Scalability Simulation

[David Andersen]

We have a similar analysis (which agrees with Vince Fuller's #s in a general sense) in the middle of a recent sigcomm paper:

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 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.


in

environment.


what parameters should I try to caputre.

Basically the goal of this testing is to study the BGP scalability issues 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 Can you suggest how I can set up the envrionment for this kind of study and

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




1) What sort of topology I should try out ?

2) What parameters should I test?


guys.

I am trying to simulate BGP for scalability testing. I have few queries. I am trying to simulate it in ns-2 and i would appreciate reply from you
