Juniper messaging seems to be geo-specific, in EU their sales seems to
sell them more willingly than in US. My understanding is that
basically fusion is dead, but they don't actually have solution for
access/SP market front-plate, so some sales channels are still
pitching it as the solution.
Would that be high-density face-plate solutions for access aggregation
in the data centre, that they are struggling with?
I haven't used their EX platform since the EX4600 broke things, and I
have never tried their QFX platform. So not sure if Juniper have any
decent switch offerings for large scale data centre aggregation in 1U
form factors, that customers are actually happy with.
Nokia seems very committed to it.
I think the solution space is
a) centralised lookup engines - so you have cheap(er) line cards
for high density low pps/bps
b) satellite
c) vlan aggregation
Satellite is basically a specific scenario of c), but it does bring
significant derisking compared to vlan aggregation, as a single
instance is designing it and can solve some problems better than can
be solved by vendor agnostic vlan aggregation. Vlan aggregation looks
very simple on the surface but is fraught with problems, many of which
are slightly better solved in satellites, and these problems will not
be identified ahead of time but during the next two decades of
operation.
Are you suggesting standard 802.1Q/Q-in-Q trunking from a switch into a
"pricey" router line card that support locally-significant VLAN's per
port is problematic?
Centralised boxes haven't been available for quite a few years, but
hopefully Cisco is changing that, I think it's the right compromise
for SPs.
I'm still a bit unclear on what you mean by "centralized"... in the
context of satellite, or standalone?
Mark.
