You are mistaken.  They use the ez-chip in non "Q" cards as well for the MX.

I think you only need to look at what the Q card does and you will see it does not marry up very well to the "traffic management" feature of the ez-chip... I think the previous poster was correct.  Ethernet framing and MAC lookup is all they are used for.

I'm sorry not to agree on this one. Unless you can prove me that I'm wrong
- Juniper uses the chips on the MX series only in -Q- Line Cards. So when
you use something only in advanced QoS line cards, there's something related
to QoS, definitely.
- Check the description of EZChip NPs on their website (
http://www.ezchip.com), they are built to provide the Ethernet framing and
MAC lookup AND traffic management). Neither Cisco nor Juniper would buy a
chip to have it do only 20% of what it could do. Cisco uses the chip in the
ES+/ES40 and in ASR 9k cards.

EZchip’s NP-2 is a highly-flexible network processor with integrated traffic
managers providing wire-speed packet processing and advanced flow-based
bandwidth control. The NP-2 offers the speed of an ASIC combined with the
flexibility of a programmable microprocessor. It provides the silicon core
of next-generation Carrier Ethernet Switches and Routers (CESR). Through
programming the NP-2 delivers a variety of applications such as L2
switching, Q-in-Q, PBT, T-MPLS, VPLS, MPLS and IPv4/IPv6 routing. The
integrated traffic management provides advanced QoS for flow-based service
level agreements (SLA) and enabling triple-play services (voice, video,

All that stuff makes me think that the 2 vendors will not release any 100G
ports (*with advanced QoS*) on MX or ASR until the EZChip NP4 is produced
(not only prototypes). That gives by the way > 2 years advance to
Alcatel-Lucent from that point of view, because their 100G NP has been ready
since last year. Funny market :)

But well, let's wait for Juniper's next week announcement.
