From YouTube: DASH Behavioral Model WG Dec 1 2022
Description
BMV2 implementation ignores and sends packet out on same interface. Test will still work with default route that is pointing to both interfaces. Gap is underlay MAC address that was pushed needs to be updated. If we can plumb in MAC address using existing SAI API.
We need P4 table updated just enough
Marian – agree MAC address portion is open
Created Issue 292 and assigned to James Lo (Accton)
Basic underlay routing bmv2 to handle MAC address updates/resolution #292
IPv6 & IPv4 scale again
A
Was
from
the
very
last
meeting
before
we
went
off
for
a
break
so
I'm
also
trying
to
figure
out
if
we
added
anything
into
the
backlog
for
the
behavioral
model
project,
so
I
believe
this
is
the
conversation
from
last
time
or
we
can
maybe
go
through
it.
A
little
bit
and
I'll
go
ahead
and
grab
the
behavioral
model
project
didn't
while
I'm
looking
for
it
did
anyone
have
a
PR
they
wanted
to
bring
up
and
cover.
A
C
A
C
Have
it
right
here
this
should
be
a
linked
issue
and
I
I
added
all
that
text.
Like
a
week
ago,
I
noticed
that
Youssef
was
going
through
and
and
kind
of
refreshing.
This
and
pinging
people,
so
I
went
in
and
added,
but
do
you
want
help
on
this
Marianne?
Is
there
sort
of
a
formula
that
can
be
followed
or
is
it
pretty
straightforward.
B
B
C
A
A
A
A
A
A
D
A
B
A
B
E
A
D
A
Okay
and
then
deployment
well
I
saw
this
line.
Deployment
topology
from
Microsoft
would
be
helpful,
so
we
did
have
the
drawing
where
we
were
saying.
You
know,
for
example,
you
could
place
this.
You
know
pretty
much
at
any
tier
in
the
data
center.
Is
that
what
we
were
talking
about
here?
I
wasn't
in
this
particular
meeting
right.
D
A
D
Say
it
again,
yeah
yeah
sure
we
needed
to
add
some
basic
underlay
routing
in
bmv2,
and
the
question
came
up
that
whether
the
packets
that
come
in
on
one
port
in
a
dpu
needs
to
go
out
in
the
other
port
or
same
port
or
how
the
Gateway
is
connected.
Do
we
is
default
routing
sufficient,
so
or
you
know,
routing
to
specific
address
how
that
will
be
handled?
How
the
connection
is
overall,
topology
wise?
What
we
expect
I
think
that's
what
the.
F
G
B
F
F
F
I
know
where
it
goes,
but
I
don't
know,
I,
don't
know
what
the
mechanism
to
force
it
that
way,
but
they
don't
do
it
randomly.
They
don't
like,
allow
it
to
come
in
one
point
in
some
profit
growth,
a
few
different
parts
like
it
all
goes
either
back
to
the
same
port
or
it
goes
out
the
other
point.
So
we
just
need
to
figure
out.
You
know
what
we
do
today
and
then
how
did
they
accomplish
directly
new
topic?
So
good
question.
F
F
F
A
A
B
C
B
A
A
A
G
A
G
G
A
F
You
know
also,
one
thing
you
can
assume
is
the
underlay.
It's
V6,
okay
and
the
overlay
typically
is
V4.
But,
as
we've
said
in
the
past,
we
have
some
big
customers
that
actually
have
V6
networks,
big
retailers,
yeah
well,
no
well-known
retail,
they're
V6,
so
99
of
our
customers
are
be
poor,
but
we
have
some
really
big
customers
who
are
V6
and
that's
where
it
is
today.
What's
going
to
happen
tomorrow,
it's
hard
to
say,
but
that's
that's.
F
You
know
when
people
come
back
like
our
overlay
should
be
V6,
because
our
network
is
V6
capable,
and
you
know
everybody
has
problems
getting
ipv4
addresses
so
that
that
I
think
is
almost
a
given,
but
the
but
the
overlay.
Today,
yes,
99
of
customers
are
V4,
but
our
biggest
customers
are
some
of
our
biggest
customers
are
V6
so
that
that's
the
data
that
we
have
for
now
help
us
customers
move
to
V6.
So
it's
very.
F
D
A
Internal
Azure
devops
and
you
know
we
we
do
know
V6
takes
more
memory
space,
but
are
there
going
to
be
as
many
entries
blah
blah
blah
and
then
before?
And
so
you
know,
of
course,
they
came
back
and
said:
well,
it'd
be
best
if
it
was
configurable,
so
I
am
still
working
with
them
to
get
you
guys.
The
best
answer,
yeah.
F
G
G
You
know
there
are
some
I
mean
there
are
trade-offs
that
that
can
be
made,
but
yeah
so
like.
If
just
if
we
could
just
get
more
insight
into
like
that
and
like
I
mean
like
Gerald
made.
The
point
like
oh
99
of
the
customers
are
going
to
be
V4,
but
the
big
ones
might
be
B6.
Does
that
mean
that
the
entire
Dash
data
plane
could
potentially
be
consumed
by
like
a
big
customer
and
where
everything
has
to
be
V6
I.
F
G
F
G
A
F
F
I
think
that
what
would
be
good
to
know
is
that
we
kind
of
put
a
limit
on
the
memory,
because
it
costs
32,
gig
or
64
gig
would
be
nice
to
know
is
how
many
IPv6
could
fit
into
32,
gig
or
64
gig,
then
that
would
be
give
them
something
to
work
with
right,
as
opposed
to
the
other
way.
Around
I
mean
right
and.
G
F
C
C
F
Well,
I
think
in
the
past,
even
if
you
go
back
through
history,
we
put
out
some
numbers
that
didn't
seem
to
be
perfect.
Let's
say,
and
after
working
with
with
suppliers
who
work
on
this,
we
come
up
with
new
numbers
which
seem
to
more
match
reality
and
I.
Think
that's
where
we
could
go
so
I
think
we
could
put
out
for
profiles.
I
think
that's
a
good
idea
and
then
just
ask
people
like
what
what
would
you
know.
F
We
wouldn't
be
able
to
share
back
the
individual
answers,
but
we
would
probably
come
to
some
conclusion
across
the
industry.
What
would
be
reasonable
and
I
think
that's
what
we
we
always
have
to
be
reasonable
right.
If
they're
not
doable,
then
it's
then
it's
there's
no
sense
asking
for
it.
So
maybe
that's
how
we
approach
it
because,
right
now
the
standard
answer
from
engineering
is
yeah
the
same
and
and
they
know
the
issue
right
so
yeah.
F
A
F
So
I
think
here
we
go
the
the
the
the
the
action
might
just
be
for
us
to
come
up
with
four
profiles,
not
telling
them
the
numbers
just
four
profiles,
and
then
we
can
ask
the
you
know
the
suppliers,
and
maybe
we
can
work
out
a
number,
because
I
think
this
is
going
to
be
circular
I,
don't
think
we
can
give
them
number.
They
don't
want
to
give
us
the
number
so.
E
F
A
F
B
G
Like
we
would
have
to
size
each
of
those
memory
pools
for
the
maximum
of
V4
and
for
the
maximum
V6.
That's
like
one
option.
Another
option
might
be
that
there's
just
one
shared
memory
pool,
but
but
when
you
use
V6,
you
don't
get
as
many
as
when
you
use
V4
and
so
like
we.
We
like
this,
is
kind
of
holding
us
back
from
like
in
a
way
figuring
out.
G
What's
like
the
right
implementation
of
managing
the
memory
and
like
if
we,
if
we
understood
better
like
what
the
requirement
is
like,
we
might
like,
another
option
might
just
be
hey.
If
all
flows
have
to
be
V6,
then
there's
just
one
pool
and
it's
just
size
so
that
all
flows
can
be
V6.
So
it's
it's.
This
is
like
we're
working
on
this
and
we
and
like
deferring
like
the
information
is
just
like.
D
F
I
wonder
if
you
know
when
we
talk
about
connection
tables
and
it's
I,
don't
know
your
implementations.
Whether
the
key
inside
the
connection
table
is
a
connection.
Id,
not
you
know,
separately,
keeping
the
actual
true
key.
It
may
make
May
mean
that
you
can
hold
as
many
there's
many
connections,
whether
they're,
ipv4
or
V6,
some
trick
to
do
that.

Nope,
okay,
then
it's
10,
36
I'll,
stop
the
recording
and
I
can
give
a
little
bit
of
time
back
but,
like
I
said,
Yusuf
went
through
the
whole
list
of
items
looking
for
updates
and
we're
going
to
close
the
ones
that
have
the
appropriate
update
and
try
and
keep
the
list.
You
know
a
little
bit
lower
and,
like
I
said
James
Lowe
wants
to
work
on
things
too.
I'll
try
and
reach
out
to
him.
So
thanks
everybody
and
reach
out
to
me,
if
you
need
anything,
it's
Chrisney
microsoft.com
or
on
teams.
