BGP Scalability Simulation

[bradfreeman at gmail.com (Brad Freeman)]

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.
