[e2e] IP Table Size

[Poh Tze Ven]

Hi,

I need some information from ISPs (more ISPs the better) regarding active
network elements (in particular, routers) that capable of routing IP packets in
their networks. The information is needed only for statistical purpose. The
following are what I seek for:

(i)  The average size of IP forwarding table (in term of number of IP prefixes)
excluding AS border routers.

(ii) The average number of external prefixes in the forwarding table (exclude AS
border routers).

(iii) The average number of external prefixes in forwarding table of an AS
border router.

(iv) Rough estimation of number of routers in the domain.

Please reply directly to my e-mail address.

Thank you in advance.
