A

A
B
A
C
B
A
Is
great,
thank
you
all
right.
So
this
is
the
agenda
of
this
meeting
is
a
little
bit
different
from
the
past
ones.
We've
we
get
to
bash
the
agenda
in
a
moment,
we're
going
to
talk
about
what
we're
doing
to
make
progress
and
how
we're
going
to
get
things
done
from
here
and
then
on.
The
want
to
start
me
start
to
draw
try
to
draw
some
conclusions
from
the
look
we've
been
taking
at
the
TSN
mechanisms
with
respect
to
the
requirements.
A
Draft
there's
a
couple
of
things
here.
First,
is
we
have
this
new
ecqf
going
on
in
I
in
802
we're
going
to
talk
about
a
little
bit
and
then
was
help
from
psf
and
ESU.
We
have
a
summary
of
TSN
mechanism.
Evaluations
to
take
a
look
at
the
goal
here
is
to
understand
where
things
sit
with
respect
to
the
requirements
draft
based
on
what
already
exists
and
it
with
luck.
It'll
it'll
shed
some
light
on
relative
importance
requirements
for
new
mechanisms.
A
A
A
A
A
Okay
for
progress
from
here,
this
meeting
is
I
think
mostly,
but
planned
for
this
meeting
and
happy
to
take
suggestions
for
doing
something.
Different
is
to
take
a
look
at
the
summary
of
the
TSN
queuing
mechanisms
with
respect
to
requirements
draft
and
along
the
way.
We
should
talk
about
ecqf
and
I'm
I've,
seen
a
bunch
of
folks
working
on
new
proposals,
who've
prepared,
one-slide
summaries
of
how
their
mechanisms
stack
up
against
requirements
in
the
requirements.
Draft.
A
A
A
A
D
D
D
D
D
D
Here
is
important
function
of
this
cup
with
C
part
for
protocol
that
is
used
to
detect
the
same
offset
between
absolute
node
and
this
node.
It
uses
two
percent
at
the
first
capacity
is
the
cpaper
timer
marker
frame,
and
the
second
message
is
to
see
purple
face
offset
mean
in
in
ctmf.
It
is
generated
by
the
CPU
and
send
the
reason
the
any
position.
D
D
D
B
I
I
want
to
emphasize
Okay,
add
a
little
bit
more
information
to
this
slide.
So
there
is
a
pre-requisite
or
there
is
assumption
for
the
CPAP
to
work
that
is
the
node
a
and
the
node
B.
Actually
they
need
to.
They
are
required
to
support
the
hardware
Hardware
based
time,
stamping.
So
the
assumption
is
the
node
a
can
record
the
first
bit
at
the
physical
layer
to
be
sent
out
and
in
node
B
can
record
the
first
bit
of
a
packet
received
at
a
particular
Port.
B
B
D
D
B
B
That's
this
will
help
CPAP
this
new
protocol
to
be
run
in
order
to
get
quite
a
very
accurate
link,
propagation
delay.
So
that's
the
purpose
of
that
and
another
thing
is
the
the
the
picture.
The
bottom
part
of
the
picture
says
is
a
receiving
bridge,
but
at
the
same
time
we
need
to
remember
for
the
receiving
Bridge,
their
incoming
port
and
the
sorry,
the
receiving
port
and
the
transmission
Port.
B
D
Also
understand
the
the
sample
remaining
issues
or
say
pop
the
first
one.
Is
you
which
fees
via
to
take
it
through
to
to
you
for
this
tool,
message
the
ones
that
Define
alternative
type
or
some
nuclear
waste
in
the
existing
lgbas
and
1588
and
lldp
another
easy,
because
there
are
two
messages.
So
the
second
message
issued
bond
to
the
first
University
to
maybe
use
to
use
a
serial
number
for
these
couples.
D
D
D
For
example,
will
attack
IP
DHCP
to
indicate
the
Target
and
second
node.
The
cellular
here
is
a
signal.
For
instance,
each
circle
will
be
allocated
a
partial
or
for
the
bundle
values,
but
the
total
allocation
must
remove
the
over
subscribe
each
second
level.
Master
contains
the
integer
multiple
Circles
of
next
to
the
first
term
load.
The
following.
These
are
examples
that
have
four
secret
students.
D
D
A
D
A
B
A
D
The
food
is
just,
for
example,
the
wheel
and
tag
or
ibdcb.
The
following
example
is
not
afraid.
The
following
example
example
is
The
Shield
the
relationship
between
multiple
Seeker,
for
instance,
for
example.
The
the
priorities
Suite
in
the
top
level
is
the
probability
it
is
a
independent
figure,
for
instance,
under
the
second
priority.
Four
is
another
single
of
instance.
This
example
is
loaded
as
rainbow
encoding.
D
D
D
A
D
Okay,
this
page
is
discussed
in
why
Unity
multiple
for
easy.
These
are
commonly
example.
In
this
example,
tc5
allocate
the
activity
percentage
or
for
the
bundle
virus,
while
she's
a
full
one.
Okay,
40,
positive
tc4
cycle
does
not
contain
anything
multiple
Circles
of
next
faster
level,
65.
So
in
the
yellow
sheet.
In
the
circles,
three
patches
of
Blue
Buster
normal
three,
which
is
a
five
Cycles,
maybe
squeeze
but
forget
our
vision,
the
course
of
one
which
is
a
full
circle.
D
So
this
page
is
about
the
time
of
business
curve,
the
the
key
feature
of
autonomic,
basically,
that
the
receive
the
frame
is
assigned
the
input
port
to
Output
bin.
According
to
the
arrival
time,
the
number
of
beans
required-
maybe
two
three
or
more
determined
by
how
many
cycles
I
improved
circles,
religious
span
and
output,
port,
and
one
knows
about
how
frequency
work
with
the
single
circular.
D
D
D
D
D
It
may
be
different
tab
so
for
each
tip,
wtp
can
imagine
a
differently
inputed
cycle
circles,
but
that
is
another
altitude
and
you
put
inside
a
service
I
guess
so
they
imagine
they
did.
The
Circle
sequence
has
the
same
cycle.
Duration
is
output
second
service.
Thus
it
is
impossible
to
assign
output
being
only
based
on
the
arrival
time
at
the
runtime.
D
D
So
this
is
the
alternate
message
of
the
user
curve,
for
that
is
a
counter-based
festival.
The
key
feature
of
convincible
for
it
and
receive
the
frame
is
assigned
the
import
port
to
Output
bin.
According
to
the
bytes
account
plus
view,
each
stream
store
no
more
than
it
is
constructed.
Amount
of
data
per
cycle
into
any
given
sake
of
being
fluids
are
power
that
they
needed
are
stored
in
the
sub
cell
convenience
and
the
access
data
that
you
see
the
maximum
amount
of
purposes
allow.
D
The
data
stream
is
discarded,
so
this
is
similar
to
vcp
with
maximum
the
interval
of
cycle.
So
this
is
our
course.
Other
features
is
that
the
volanos
use
nearly
single
cycle
nowhere.
So
it
is
not
required
protagonist
semicellular
because
it
is
by
the
car
in
the
history.
The
second
phase,
corresponding.
D
A
D
There
are
two
keys
for
the
flow
aggregation
first
case
is
a
typical
case
that
from
Earth
to
Pogba,
the
new
bandwidth
is
the
changes
tonight,
so
the
few
aggregation
nation
and
in
the
earth
University
May
configure
the
cycle
with
largest
other
in
the
backbone.
The
second
may
be
configured
with
symbol
sets.
D
D
The
aggregate
employees
should
use
contact
with
being
assignment
messages,
communities
that
the
time-up
is
being
assignment
requires
the
input
cycle,
duration,
the
output
circuit
duration
to
be
equal
and
the
time,
obviously
being
assignment,
is
harder
to
process
concluding
the
arrival
films
of
component
streams.
If
you
output
faster
secret
instance,
as
a
node
allocated
the
mobile
awareness,
our
recent
aggregated
segment
time
basically
applied.
D
D
We
can
take
a
look
at
the
node,
a
for
easy
stream.
This
is
the
component
industry
for
each
stream,
one
free
more
per
cycle,
for
example.
Here
the
cycle
is
one
milliseconds,
the
required
for
the
sales
for
for
the
screen,
because
somebody
that
is
one
from
the
site
for
one
milliseconds,
so
the
total
required
abundant
values
for
water
streams.
It's
way
more
volumized
divided
by
one
milliseconds,
so
the
secret
resistance
here
is
the
one
millisecond
distance.
D
Component
screens
are
regarded
as
the
same
availability,
the
stream
we
terminate
with
us
Force
streamer
as
one
flimer
per
cycle.
He
the
cycle
is
faster.
It
is
just
for
using
733
micro
signals
required
by
this
one
from
the
sites
approach.
She
misses
me
local
settings,
so
the
sake
of
submissive
is
sleep.
Medical
seconds
instance
are
located
bounded
by
this
one
thing
that
says:
police
solution,
three
magnets,
that
is
the
same
as
a
single
one,
millisecond
distance,
the
output
pin
set
of
a
single
for
33.
D
D
D
So
for
the
disaggregation
is
told
about
how
to
change
from
a
fast
and
save
level
to
slow
a
second
level
for
Speed
under
this
degree,
aggregated
node.
This
is
similar
to
aggregating
community.
This
creating
quality,
also
use
counter-based
beam
assignment.
The
Flames
of
the
universities.
Aggregated
strings
are
distributed
in
the
slow
out
proteins
in
the
domain
foreign.
D
D
D
D
And
the
third
item
is
a
tail
tailored
by
the
way
this
is
often
is
you
offered
the
customer
only
a
specific
set
of
choice
for
a
bundle
Riders
to
contract
corresponding
to
the
Oneness
of
TC
implemented
in
the
providers
to
improve
our
population,
and
the
first
item
is
about
if
cyber
time
will
report
to
the
regulated
in
the
internet.
In
this
case
one
free
motorcycle,
otherwise,
both
faster
the
cycle
level
can
be
used
under
this
bundle
Riders
to
visit
it.
A
A
E
D
From
the
standard
I
have
noticed
the
formula
about
the,
for
example,
under
the
under
latency,
but
just
have
some
section
describe
the.
However,
it
indicates
the
underground,
ladies,
must
include
the
the
many
types
are
due
to
the
cycle.
Phase
of
this
is
a
key
difference
from
the
traditional
TSN
Seeker.
A
E
E
D
D
E
D
E
D
E
A
B
B
What
are
the
comments
from
you
and
what
other
the
text
from
the
current
draft
I
can
tell
that.
There's
slide.
As
you
said,
the
slide
four
basically
is
a
comment
from
you
right.
The
slide
four.
Is
there
any
anything
else
that
actually
are
there
the
the
comments
for
the
draft,
but
not
the
draft
itself.
D
He
I'm
not
sure
I,
don't
understand
the
question.
I
just
sent
some
comments
about
the
goody
way
to
jealous,
but
in
decent
selection.
We
just
good
at
the
some
more
important
virtues
of
risk
to
know
some
big
difference.
Traditional
Seeker
under
under
two.
We
can
give
our
information
to
the
notification
requirements.
B
So
I
guess
my
question
is
I
can
see
that
the
slide
for
what
said
in
slide.
4
is
a
comment
to
current
udb
Drive.
The
text
right.
It
is
not
in
current
2db
draft.
So
is
there
any
else
anything
else,
because
qdb
is
is
still
in
very
early
stage,
so
so,
for
example,
the
last
slide
is:
is
it
in
the
current
qdv
text
or
it
is
something
like
you
comments
you
want
to
make
to
qdv.
D
A
A
F
F
A
F
Yes,
yes,
yes,
thank
you
actually
I
I,
think
I
think
the
features
leads
to
begin
in
the
right
hand
for
using
that
is
quite
quite
similar
to
what
we
want
to
solve
or
to
raise
the
SKF
or
key
City,
for
example,
there's
no
requirement
for
our
time.
Synchronization
there
is
a
mapping
relationship
maintained
each
node.
We
are
on
the
10
unit
councilor.
F
F
D
F
Okay,
so
so,
if
that
is
the
case,
I
think
what?
What
is
my
comment
is
that
maybe
we
we
should
consider
whether
we
we
are
going
to
introduce
so
many
Concepts,
because
because
they
there
are
have
already
a
lot
of
mechanisms
and
those
names.
If
we
also
try
to
introduce
new
Concepts
to
just
summarize
the
existing
mechanisms,
maybe
we
should
be
more
careful
about
the
school
of
the
concept
and
what
should
be
your
side
and
what
should
be
outside?
F
F
D
I
have
a
short
responsible
for
your
service
quality.
You
can
take
a
look
at
the
easy
cups
we
we
will
see
a
key
feature
of
these
adults
is
that
you
just
either
just
assign
things
to
Flame
according
to
the
arrival
time,
that
is,
it
seems,
abandonment
from
the
at
one
time,
maybe
some
enhancement,
for
example,
College.
Some
big.
F
Yeah
I
think
so
that
is
my
proposal.
I
think
what
actually
you
should
do
is
that
will
if
they
want
to
introduce
New
Concept
it.
It
is
also
their
opportunity
to
see
what
has
already
been
done
on
your
idea,
just
like
what
we
will
do
before
we
try
to
make
some
extensions
to
existing
article.
You
work
so
I
think
we
should
clarify
the
relationship
together.
F
I
think
I
understand
your
point.
Shampoo
is
that
the
this
concept
may
try
to
take
the
common
features
of
these
locations,
but
I
think,
for
example,
the
reference
is
is
very
necessary
and
what's
more
inside.
This
also
should
be
clarified.
I
think
I
mean
what's
more.
Is
that
besides
local
idea,
work?
What's
more
can
be
done
or
what's
new
in
this
contract.
A
A
B
Yeah,
so
the
the
easy
query
is
enhancement
to
secure.
If
it
is,
it
is
a
pretty
new
project
in
IEEE
802.1,
so
it
is
still
under
development.
I,
pretty
much
sure
there
are.
A
lot
of
things
has
not
been
fixed,
so
I
guess
the
purpose
of
current
stride.
Deck
is
trying
to
give
a
brief
introduction
to
ecqf,
which
is
defined
by
qdb.
By
the
way
it
is
has
not.
It
has
not
been
done
that
how
their
tcqf
or
CS,
what
sorry,
csqf
and
all
the
other
relevant.
B
B
For
example,
you
try
to
lose
the
requirement
for
the
time
synchronization
so
that
their
different
nodes
can
use
their
sorry
that
can
can
have
the
unsynchronize
the
cycle
boundaries
and
also
it
allows
both
the
time
based
buffer
opening
selection
in
the
account
based
buffer
of
being
selection
and
at
the
same
time,
and
there
it
allows
the
multiple
traffic
classes
to
be
included
in
the
c2f.
That's
why
it's
called
originally
called
multiple
secure,
multiple
means,
multiple
traffic
classes,
I
I
think
so.
So.
B
A
quick
comment
to
how
it
is
different
to
tcqf,
in
my
mind,
is
the
first
thing
is
because
the
ecuf
is
defined
by
IEEE.
So
it
has
a
quite
a
valid
assumption
that
between
two
neighbor
nodes
there
is
only
a
point-to-point.
Physical
link,
that's
interesting.
The
second
thing
is,
there
is
a
hardware
timestamp
available
so
that
it
can
use
the
time-based
reception
time
to
determine
which
one
which
output
being
should
be
put
for
a
particular
packet.
B
So
for
tcqf
we
try
to
divide
in
Internet
which,
which
has
a
mouth,
which
has
a
more
complex
topology,
possibly
so
it
may
not
be
a
point-to-point
physical
link
between
two
neighbor
nodes
and
also
there
are
some
other
unexpected
time
variations
between
two
nodes.
For
example,
there
could
be
some
large
clock,
sorry
clock
drift.
We
call
it
mtie
I
think
in
the
in
the
draft,
so
that
it
is
not
always
true
that
the
constant
propagation
delay
is
always
available.
B
A
A
B
A
So
this
is
an
enhanced
version
of
the
slide
deck
we
used
last
time.
Maybe
the
thing
so
anything
to
do
quick
might
be
to
start
with
what
the
sheet
qfe
evaluations
were.
Xiaofu
had
done
one,
and
is
you
had
done
one
the
the
they're
pretty
close
to
each
other
I
think
the
only
difference
was.
Let
me
quick
check.
A
D
D
D
D
D
D
D
D
B
A
A
Okay
and
then
I
put
together
an
initial
scorecard,
and
the
purpose
of
this
was
to
take
a
look
at
what
is
already
available
or
in
case
of
ecqf,
hopefully
coming
soon
from
IEEE
against
against
our
requirements,
and
you
can
read
the
details
down
the
evaluation,
we're
just
counting
and,
in
the
right
hand,
column
on
notes
listed
the
ones
that
aren't
yes.
What
I
wanted
to
call
attention
to
is
the
two
requirements
for
which
we
have
no
Roots.
E
A
C
E
E
A
E
E
B
B
E
D
Maybe
it
has
some
different
supported,
for
example,
ATS
I,
don't
think
it
may
provide,
for
example,
multiple
instance
for
some
type
of
class
in
May,
configure
the
pre-configure
reserved
bundle,
riders
that
detained
the
boundary
latency.
So
this
this
was
case,
abundant
latency
is
applied
to
any
flows,
belongs
to
this
travel
class.
E
A
A
G
Yeah
for
the
partial
evaluation
and
I
have
a
suggestion.
If
we
can
make
a
clarification
for
the
requirements
with
the
partial,
if
we
can
clarify
and
Define
our
definitely
to
figure
what
a
binary
value
or
other
clarification
for
the
repellent
with
partial
that
we
can
distinguish
the
mechanisms
with
a
death
later
low
or
does
it
yes
and
then
we
can
distinguish
their
mechanisms
with
the
the
mechanism
that
can
apply
can
be
applied
in
large
scale
and
within
a
low
the
you
have
a
low
evaluations.
G
A
G
Classification,
for
example,
the
first
part,
is
the
overall
requirements,
just
like
the
the
3.6
and
the
3.8
is
the
overall
requirements
for
the
network
capability.
I
think
it's
a
it
must
be
made.
The
the
requirements
must
be
satisfied
forward
mechanisms
under
the
other
requirements
such
like
the
3.1
3.2
and
this
3.3,
and
they
are
the
requirements
requirements
for
the.
G
Mechanisms,
it
must
be
yes
and
for
other
requirements
such
as
there's
3.4,
3.5
and
3.7.
They
are
for
the
flow
and
the
traffic
scheduling
like
even
if
they
can
be
partial
for
for
their
like
evidence,
so
it
is
okay
for
for
their
mechanisms
with
the
partial
evaluation,
I
I,
don't
know
if
I
make
my
my
clarification,
clear.
A
A
Hang
on
I
need
to
type
one
more
word
here.
Okay,
so
I
think
I
heard
you
catch
on
two
things.
The
first
is,
it
sounded
like
you
had
some
ideas
for
how
to
clarify
the
3.7
requirements
so
that
we
can
get
a
better
evaluation
of
whether
the
scaling
is
is
good.
It
with
the
scaling
is
really
good,
partial
or
not
acceptable
is
is
okay.
Could
you
that
sounds
like
its
effects
requirements
draft?
G
A
Okay,
well,
it
sounds
like
we
what
I
think
I'm
asking
you
to
do
to
begin
with
is
to
focus
on
the
3.7
requirement
where
we
have
a
week.
I
hear
a
lack
of
a
an
absence
of
agreement
on
whether
linear
scaling
with
with
hop
count
is
yes,
acceptable
or,
or
or
or
only
partial
and
I,
think
the
requirements
draft
ought
to
take
a
position
on
that.
A
G
A
Go
particularly
because,
certainly
for
the
first
few
requirements,
we
have
no
problems
for,
let's
see
for
at
least
these
the
first
few
requirements,
we
don't
have
a
problem
with
the
existing
existing
mechanisms
that
meet
them,
whereas
for
at
least
the
two
scalability
ones.
Since
we
initially
came
up
with
no
yeses,
we
do
have
clear,
clear
issues.
There.
A
A
Okay,
all
right,
let
me
in
15
minutes
that
remain.
Let
me
suggest
where
what
we
might
do
for
the
neck
for
the
next
meeting,
which
is
it's
in
it's
in
three
weeks
that
the
calendar
was
carefully
picked
to
avoid
the
early
September
holiday
in
the
U.S
Monday
September
4th
is
a
major
U.S
holiday,
and
so
a
lot
of
people
will
may
not
be
around
on
on
Tuesday
the
5th.
A
So
we're
going
out
we're
going
to
go
three
weeks
in
general,
and
let
me
suggest
that
we
in
the
next
meeting
start
looking
at
this
sort
of
single
slide
evaluation
for
the
new
mechanisms,
but
I'm
a
little
bit
concerned
that
I'll
pick
on
ecqf
a
little
bit
concerned
that
just
asking
for
the
single
slide
is
going
to
be
too
short.
I
mean
we
sort
of
saw
that
in
this
meeting,
where
starting
from
this
slide
was
the
wrong
place.
To
start
the
right
place
to
start
was
the
was
the
more
detailed
explanation.
A
So
maybe
and
I
will
take
this
to
the
list.
I
will
take
this
to
the
list,
so
this
please
please
don't
take.
This
is
anything
more
than
David's
initial
suggestion.
Maybe
what
we
want
is
a
summary
slide
like
this,
for
each
of
the
new
proposals,
accompanied
by
a
small
number
of
slides
that
help
explain
what
what
these
evaluations,
why
the
evaluations
are
what
they
are
in
a
little
more
detail
than
is
possible
in
the
notes,
column.
E
A
I
can
yeah
and
what
I
think
I'm
gonna
do
is
I'm
going
to
put
I
will
send
something
to
the
list.
I'm
gonna
put
I'm
going
to
want
to
put
a
both
a
slide
count
and
time
restriction
on
this,
because
in
order
to
do
a
fair
job
on
the
new
mechanisms,
we
really
should
try
to
make
a
first
pass
over
all
of
the
evaluations
in
the
next
two
hour
to
our
meeting
at
30
seconds
at
30
minutes.
Excuse
me
holy
smokes.
I
need
more
coffee
this
morning
at
30
minutes
of
mechanism.
A
A
A
Yeah
but
I
would
like
to
to
have
the
next
meeting.
Is
an
evaluation
slide
like
this
one
for
every
one
of
the
new
proposals
people
would
like
to
have
considered
and
then
the
evaluation
slide
would
probably
need
a
supporting
slider
to
particularly
for
the
two
scalable
requirements.
Three
four
and
three
seven
that
are
causing
us.
The
most
difficulty.
A
Okay
and
I'll
put
this
on
the
list,
and
I
will
try
to
get
that
done
done
this
week.
So
we
can
have
some
time
for
discussion
and
agree
on
what
it
ought
to
be
before
people
start
investing
a
lot
of
time
in
preparing
slides
and
I
mean
if
we've
already
prepared
something
that
looks
like
this
evaluation
slide,
you
should
be
able
to
reuse.
It
I
think
the
new
slide
work
might
just
be
a
little
bit
more
explanation,
particularly
on
the
two
scalability
requirements.
