Some might not see that as necessarily a bad thing, provided
the ASIC is robust enough to handle all of the user's
required features in the hardware path (being the only path)
:-).
This is one of the things we like about vendor J - packets are either
forwarded in software or not at
Yeah the software forwarding idea just ends up crashing large boxes like the
7609. If you suddenly enable a feature that causes software forwarding or
you run out of TCAM and software starts to make up for that, say goodbye to
either performance or your SUP/RSP.

I think they'd like to in the future but the problem still exists that IOS
is monolithic based and has a horrible time making good use of SMP, One of
the reason they've stepped away from IOS for the Nexus/ASR platforms.

Agreed. Its particularly curious on the ISR, since its still a software-based
platform and not positioned for heavy IGP/EGP workloads. SMP for NX-OS/XE/XR
where its just the control-plane is a lot
We're looking at several options for the multi-core CPU. Offloading
specific features, management, apps, HA options. We've looked very
closely at some of the other attempts to use multi-core processors
across Cisco and are trying to learn from their experiences.

I was just reading the 3925/3945 announcements and notice they're plugging
multicore processors. Given brief and violent life of MPF on the NPE-G1,
this seems surprising. Does anyone know what the plans are to actually
utilize these?
