This is how Juniper and other vendors present it. But it's very
questionable if you really need a dedicated set of queues per subscriber
Hi Pavel,
HQoS is needed for subscriber aggregation, exactly for the case that is
discussed in another thread "Juniper buffer float".
NG cards without HQoS can be configured for "flexible mode" which is
HQoS limited to 32k queues. It's suitable for example if you have some
number of vlans and

Without going into too much detail (again),
If all your traffic
High level diff:
MPC2E
2xPFE@40G each
No IR license mode (all features but 32VRF limit per MPC)
Minimum Junos 11.2R4
MPC2E-NG
1xPFE@80G
IR license mode available
Minimum Junos 14.1R4
Requires SCBE or SCBE2
More details here about specific features: (dynamic power, flexible
queueing, hqos, l2tp
Hi,
If memory serves, MPC2-NG is much like MPC3-NG: one MPC5-like PFE inside. A
good question is what is the difference between the MPC2-NG and MPC3-NG...
I'll let the astute readers figure it out on their own.
Old MPC2 non-NG is the "first generation Trio"-based card: two PFE, one per
MIC.
Hey Rolf,
No that's not it, that's difference between Q and non Q card. All
three generations had HQoS support:
1) MPC (Trio 1.0)
2) MPCE
3) MPCE--NG
I'm not sure about difference, MPCE I believe got better oscillator
for timing and I think more linecard cpu dram for higher subscriber
scale.
Hello,
as far as I see the feature difference is HQoS:

Hi list,
Can anyone tell me the differences in scaling or features of the
MPC2E-3D-NG-R-B vs MPC2E-3D-R-B. I know the NG requires an SBCE2.
Thanks,
Kevin
