Do you get commission from Juniper?

 

Where do I get my comission then? Iīve described inferior product as 
such many times
and so far I havenīt seen deposits from vendors in my bank account?

Keep in mind, 72xx is still flow-based, so you need to count *both* shared 
fabric capacity (aka PCI buses) and capacity of NPE to establish flows 
(aka pps rate).

NPE-G1 might probably route 3*GE, without any services and if all 3GE are 
in a single flow, but will melt down at a face of one-packet-per-flow DDoS 
(read: "Nachi" worm) at a far lower rate (I'd be surprised if it sustains 
200kpps DDoS traffic, which can be as low as 150Mbit bandwidth). 

That is of course, as opposed to Juniper, which is truly line-rate at any
interface, with any services, at any composition of traffic.

Does anyone have definitive speed results on the 3 "built-in" Gig ports
on the NPE-G1?  I know that they aren't attached to the PCI Buses, and
don't consume bandwidth points, but all of that is mute.  Can all three
of the ports do line rate Gig?  The Gig PA is limited to 400Mbps.  I
have seen posts that allude to the fact the max throughput on the 3 Gigs
are 800Mbps.  It's is like a big mystery that cannot be solved.  With a
"J" M7i, I know I'm going to get line rate per port up to the total
forwarding capacity of the FPC.
We are trying to create a comparison matrix and any info you have would
be great.

One more interesting feature - if you need a 4th GigE port, you can add
the GigE I/O card which still uses none of the bus bandwidth points.
The buses are fine for OC3 and below...
