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. ________________________________ From: Roger Gabarit <roger.gaba...@gmail.com> To: Richard A Steenbergen <r...@e-gerbil.net> Cc: Juniper-Nsp <juniper-nsp@puck.nether.net>; cisco-...@puck.nether.net Sent: Saturday, October 24, 2009 5:56:18 AM Subject: Re: [j-nsp] [c-nsp] juniper trinity > > On Fri, Oct 23, 2009 at 12:54:40PM -0700, Marlon Duksa wrote: > > This Trio or Trinity, whatever they call it is internally grown > > technology...a combination if EZChip + I-chip functionality. > > > > Plus I don't think it is a good strategy for Juniper to use third party > > vendors as this will not give them differentiation... > > I've heard people make this argument, but it is absurd.

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. Quote : 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, data). 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.
