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

[Tails Pipes]

Mojatau, Big switch, cumulus, arista and even juniper are trying to move
networking to a better place, but not cisco. they do contribute to it,
there is xdp, ebpf, quagga, vrfs in linux...etc < do you want to deny those
? just because you have a ccie and you are comfortable being a cisco
network guy, well you dont live alone in the world, others also need to be
able to run networks without having to work on it for 10 years.

What do you mean that no one is pushing packets in linux ? Isnt that the
point of all the linux networking ? are you saying that the vendors
mentioned are closing their work ? can you give an educated opinion who
exactly is not allowing packets to be pushed in linux ? is it Linus
trovalds and the NetDev folks or is it the community of people like you
that are so comfortable in their own skin that they dont allow innovation
to take course.

Linux and BSD are both operating systems that are well documented and many
people can understand and work with but if you are so comfortable with IOS
variants, that doesnt mean that every one is....can i operate networks
without having years of experience and implicitly forced support by cisco,
I am sick of having to learn all the cisco specific terms to all sorts of
different boxes and technologies, all their tools and super expensive AS
engagements, but thats not what this post is about. its about how a company
is making use of free software and refusing to allow it to flourish, the
microsoft of networking is cisco.

This is about a company that smiles in my face, telling me that Linux is
bad for me and they are using it in all their products, in that video, the
speaker says we can leverage all the linux work for free.

Is Cisco working on XDP ? https://netdevconf.org/0x12/schedule.html I dont
see Cisco's name here but others are.

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.
