Re: [c-nsp] Leaked Video or Not (Linux and Cisco for internal Sales folks)

open APIs tops that funny abuse list IMHO :
https://github.com/OAI/OpenAPI-Specification/issues/568

can we change the topic of the thread to an informative one, instead
of a leaked video or not, to why exactly do network engineers are
often confused by the abusive marketing all over the place of what is
open and what is not and other computing terms.

I guess this is happening in networking more often than other domains
because networking people didnt get a chance in their career to learn
about the world of computing, their heads were somewhere else,
learning about  complex networking protocols and not the common
computing interfaces, the open source world, existing  frameworks and
paradigms, this video helps a bit on how did this happen:
https://vimeo.com/262190505https://vimeo.com/262190505

has anyone here seen list of topics that network engineers usually
miss on their journey ?  i know they never get exposed to software
development and engineering in general, databases, web technologies,
operating system fundamentals.

opinions ?

danke,
markus

Unfortunately, like many other industry terms, "open" is becoming a
meaningless marketing buzzword much like "cloud", "converged", even
"redundancy" or any other technical term that has had its definition
diluted as time goes on. We're all well aware on the ISP side that it
only takes one Fortune 500 to start using a buzzword incorrectly, then
the rest of the big guys all the way to mom and pop shops around the
world start using it in the same context. Unfortunately I don't see
any end to this trend in sight.

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.

can you easily answer this question ? why packets are not pushed in
linux ?
is it because of big switch, cumulus, pica8 ?

can you push packets in linux without writing code to do that ? who is
writing
that code ?

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,
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.


Oh and with regards to:
<  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.
