Any recent predictions for routing table growth?

2008-11-03 Thread Brad Freeman
Hi,

I am looking for some recent estimates of future IPv4  IPv6 routing table
growth, the most recent reliable estimate I can find was done by Vince
Fuller in his presentation in March 2007, is there any newer or alternative
figures out?

Thanks

Bradley

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

 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.
