The Bits, Nibbles, Bytes and Words event will be held
on day 2 of Netdev 0x12 conference at the outdoor
terrace of the Hyatt Regency on July 12th at 6 pm[1]
with a beautiful view of downtown Montreal.
We will be serving cocktails, bits and bites and an
opportunity to network between attendees, sponsors,
and open source linux networking projects. Food bits
will be nibbled on, bitten into, and words (only big
words, the best words!) will be exchanged!
This event is open to all attendees and anyone
accompanying them to the conference (family members,
etc - dont have to be registered). We just ask that
if you are bringing someone just let the registration
desk know when you pick your badge so we can plan
better for food and drinks.
We will have tables for sponsors for marketing and
recruiting. We will also provide a table for any
project that is open to make attendees aware of their
work (we will send out a separate note requesting open
source projects to request for space).
cheers,
jamal

UDP segmentation was recently introduced to the Linux kernel.
In this talk, Boris Pismenny and Yossi Kupperman present their efforts
towards supporting UDP segmentation offload with existing net devices.
They will talk about limitations they encountered and how they
overcame them. Based on these experiences, Boris and Yossi
have some suggestion on how to improve the Linux networking stack
to generalize their work and make driver development easier.

Field applications and IoT require low latency (we are talking
Sub 10 msecs), high throughput and secure, and highly reliable
communications.
Think traffic intersection monitoring, remote surgery, industrial
robotics, etc.
How do we get there on Linux?
Tom Herbert will chair a session which goes into these requirements.
He will try to motivate the discussion with a live physical demo of
traffic intersection using a slot car track.

New Moonshot talk accepted!
With the emergence of switchdev as the canonical NIC-switch
representation comes the view that we need to expose each switch port as
a singular netdev.
There is, however, an impedance mismatch between that model and a few
important use cases.
Take for example the need to scale performance of high speed ports;
where a reasonable approach is to spread a single NIC-switch port's
traffic across multiple PCIe devices. A single netdev representation
doesnt cut it for that scenario.
There are other use cases of which involve hierarchies of VMs/containers
where more of these issues emerge - for these use cases there have been
discussions to use 2 or 3 netdev layers; however, even there some
challenges emerge.
Anjali Singhai Jain and Sridhar Samudrala make the arguement that the
switchdev port representor as is is not the best fit for these use
cases.
In this talk they are putting forth a proposal that they feel will
cater to various use case needs while maintaining strong control over
the resources proposed by the switchdev model.

New workshop accepted.
Roopa Prabhu will chair a discussion on Open NOS for ASICs.
Various topics on Linux support for switch ASICs will be discussed:
- New hardware support
- Hardware Resource management updates
- Scaling routing fib and bridge forwarding database
- Building Network virtualization solutions: E-VPN
- Network Configuration Management, Debugging and
troubleshooting
- Futures

We are pleased to announce our Netdev 0x12 keynote
speaker: Van Jacobson
For most people involved in the networking world, Van will
need very little introduction for his work, amongst many,
in TCP/IP network performance and scaling of the internet.
For the young lads amongst us who may be oblivious of his
accomplishments, Van is what you folks typically refer to
as a G.O.A.T(Greatest Of All Time) and some of us would
refer as a living legend[1]. A few of his accomplishments
are listed on his Internet Hall of Fame Induction bio:
https://www.internethalloffame.org/inductees/van-jacobson
This announcement space is too small for us to enumerate his many
accomplishments and current passions - but we wanted to highlight
one buzzword in particular:
You would not have EBPF today if Van was not there[2].
At the moment Van is involved, at Google, in a passion of
his - Network Performance Scaling.
Having Van at this conference is both a privilege and an honor as
he has seen a lot of ideas take wing from the early days of the
internet to the specialized roles around Data Center, Web, IOT and
more that we see today.
We wish to learn from this sage.
To paraphrase European Communication Magazine[3]:
"When Van Jacobson has something to say, people listen."
And Van has something he wants to say to us at Netdev conf 0x12:
We need to teach Network Interface Cards about time.
What kind of surgery do we need on the kernel NIC interfaces?
What kind of features do NIC vendors need to provide?
Come and listen to Van.
cheers,
jamal
