Was wondering if anyone here could recommend a Traffic ananlizer,
one that can show us where our traffic is destined for and how much that,
peer, or site is getting?

Thanks

NetFlow and related tools. Cisco's own NetFlow and CAIDA's cflowd tools are
the two I'm familiar with.

What kind of additional load (CPU, RAM) does NetFlow put on a router
(say a 7505 or 7513)? How does it work with CEF (along side it or in
place of it)?

I recently turned it off on one of our 7206's where it was using about 6mb
of RAM and increasing the CPU load by about 20 points. 128mb doesn't go
as far as it used to.
