Engine 0/1 - Think 7500 VIP technology, software IP forwarding
Engine 2-4 - Highspeed forwarding ASICs with adjustable microcode for line
rate forwarding.
Engine 3-4+ - Offer higher speeds then Engine 2 cards and more ASIC support
for advanced features (MPLS, CAR, ..)
Feature support (Sampled Netflow, MPLS, ACLs, CAR, ...):
Engine 0/1 - Features supplied by software so they can be used at the same
time, but throughput suffers as features are added.
Engine 2 - Cisco creates multiple microcode sets that only support several
features at the same time. Right now you
can't do CAR and sampled-netflow on the same Engine 2 card.
Engine 3/4/4+ - The cards have more ASIC support to perform multiple
features at the same time.

Subject: [nsp] GSR Engine 1/2/3/4? huh?
Hi,
is there a document that explains the difference between "engine 1",
"engine 2", ..., "engine 4" line cards for the GSR?
Is there a simple way to say "this one is better than that one", like
"the higher the number, the better the card"?
