Thanks, but those products are not routers and switches... they TEST the
capabilities of routers and switches. I'll try to remember that tidbit of
using routers AND switches. It might come in handy one day... glad you
pointed that one out.  Have you considered the possibility of writing a
white paper on that idea and sharing it with the group?

I'm not an idiot.  In the future, it might be good advice to not assume that
just because you're not familiar with something you know more than someone
else.

Sounds like you need more of highend routers...None of those you mentioned
mean much to me, I would be looking more in the direction of Lucent,
Foundry, Riverstone, Cisco...

And for big jobs use seperate products: Switches AND Routers.

Looking for comments/experiences/war stories on testing products, such as
Smartbits, Ixia, Adtech, Agilent, and Ganymede.

Desired functionality:
L2: 10/100/1000 Ethernet, ATM, FR, POS, PPPoX session generation
L2.5: MPLS, MPLS-TE
L3: BGP, OSPF, RSVP, Diff-Serv
L4-7: closed-loop testing (i.e., effects of TCP windowing and
other types of
flow control), VoIP, streaming media, etc.

Not entirely happy with current vendors... Smartbits seems ok for
L2, but L3
sucks, often too cumbersome to be productive, and I found some
descrepancies
and reporting problems with Smartbits, which makes me not want to
trust it.
Agilent seems to be good at L3, but lacks L2 testing
capabilities.  Ganymede
is good if you want to test application functionality.  Past
experience with
Adtech was L2 only.  No clue who makes anything decent to test MPLS,
although I believe Agilent does.

Experience with the current vendor market is that they all have their
strengths, so you really need a mixture of products to do
adequate testing.
Just curious if others have similar experiences.  Off-list replies
welcomed...

Thanks,
Tim
