Do you get commission from Juniper?

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. -alex On Fri, 30 Jan 2004 Jack.W.Parks@alltel.com wrote:
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...
