All this forking weakens a vendor's position in some respects, because
when BU's are presenting one company as 6,000 ones, it's difficult for
buying consistency.
Options are great, but when options have options, it starts to get ugly,
quick.
Ah well...

That is the hope. We've been to the cinema for this one before, though.
Quite a few times. So I'm not holding my breath.

Not all of it - remember the big pink elephant in the room, the NCS
6000? That is/was nPower. Again, sending customers in all sorts of
directions with that box, where now ASR9000 and the new 8000 seem to be
the go-to box. Someone can't make up their mind over there.

When you're building boxes for one or two customers, things like this
tend to happen.
But like I've been saying for some time, the big brands competing with
the small brands over merchant silicon doesn't make sense. If you want
merchant silicon to reduce cost, you're better off playing with the new
brands that will charge less and be more flexible. While I do like IOS
XR and Junos, paying a premium for them for a chip that will struggle
the same way across all vendor implementations just doesn't track.
Mark.
Yes, for sure NCS6K was a completely different beast, much as NCS1K, NCS2K. Not sure why the NCS naming was adopted vs. ASR, and then dropped for 8000/8200. Probably lots of battles within the Cisco conglomerate.
Not defending, just observing. Either way, networks got to get built, debugged, maintained, debugged, upgraded, debugged. All while improving performance, managing CAPEX, reducing OPEX.
