[c-nsp] network probes / netflow vendors

[christian.macnevin at uk.bnpparibas.com]

Hi all,

I've received a quote for a couple probes and whatnot for a new network 
I'm building. It came to
a staggering bill of half the value of the entire network (which is full 
of redundant sup720s, 67XX line
cards, 10Gb and more DFCs than you can shake a stick at.) So, we laughed, 
they laughed, we laughed,
they stopped laughing. Turns out it wasn't a joke.

So. I'm now in the market for a less humorous monitoring solution. Does 
anyone have any particular
suggestions for good, not psychotically priced LAN monitoring solutions? 
I've heard that crannog is
a great netflow analysis tool in the past, so I'm going to talk to them. 
We're using multicast heavily
(it's finance) so we need something that can handle that. We'd also like 
some deep packet inspecting
abilities, and if possible, recording for post incident forensics. I'm 
expecting inline probes to be the
biz there.

The offending vendor sounded a bit like Met Trout, incidentally. (I don't 
particularly want this post
coming up on searches).

Thanks
Christian.
