No, things changed there as well. Lookup merchant sillicon, and revise this
post every 6 months. have you heard of Barefoot networks? The days of ASICs
from Cisco are gone and we are glad, we tested the P4 DSL (cisco never got
that right with mantel) on Nexus and its wonderful.
The asics you speak of are no longer important or valuable because people
realized that in many networking planets and galaxies, the asic is reflects
the network design, they are related, and specifically for the data center,
the clos fabric design won, and that does not require fancy asics.
I guess your knowledge is out dated a bit. Cisco itself is using those
merchant sillicon ASICs happily. (lookup Chuck's comments on nexus9000,
best selling cisco switch ever)...guess it is a good switch, because bright
box pushed cisco to do that, and if any one on this list can disagree with
me here, i'm up to that challenge.
What i have discovered recently is that things happen in following way.
Your boss or his boss picks a work culture (no one gets fired for buying
IBM/Cisco), that culture (buying the shiny suits) impacts how you do work,
it makes you select vendors (the ones that sends me to vegas every year)
and not the right network design, you select cisco and you are stuck there
for life, because once they tell you how things should work (aka :
certificates), things are worse, now every time you make a new network
purchase (afraid of new CLI ), you will not be able to look the other way
because you just dont know any thing else (and loosing your certificate
value).
I wish the culture would change to, no one got fired for buying closed but
didnt get promoted either. change requires boldness.

don't worry no single company owns the whole industry.
Also we can argue that this is only about the OS but in reality it's also
the quality of apps running on top and the quality of the underlying HW
that plays a major role.
The quality of BGP app for instance, or the ability of the forwarding ASIC
to deliver the stated pps rate even if multiple features are enabled or
protect high priority traffic even if ASIC is overloaded.
< I am sick of having to learn all the cisco specific terms to all sorts
of different boxes and technologies
I'd recommend you read all the cisco books on networking to get yourself
educated on the topic and to get the difference between SW and HW
forwarding ( -on why packets are not routed in linux)
And while on that I suggest you read all Stanford university lectures on
how routers work too, it'll help you understand why Cisco and Juniper ASICs
are so much more expensive than white-box ASICs.

can you easily answer this question ? why packets are not pushed in

can you easily answer this question ? why packets are not pushed in
is it because of big switch, cumulus, pica8 ?
can you push packets in linux without writing code to do that ? who is

this is supposedly a community effort, something that older generations
dont understand.
If pure linux as NOS has some legs it'll fly regardless of cisco blessing,this is supposedly a community effort, something that older generations
dont understand.
