Description
IETF 116: IAB Open
The Internet Architecture Board (IAB) will hold an open meeting 06:00-07:00 UTC on 30 March 2023 providing the usual updates on various administrative and operational topics.

How
do
you
reach
us?
We
do
have
a
mailing
list,
I.
Think
most
people
probably
know
it's
IAB
iab.org
for
anything
that
you
need
to
comment
to
us
about
note
that
the
mailing
list
is
not
just
the
IAB
members.
There's
a
list
there
that
I'm
not
going
to
read
but
there's
actually
a
fair
amount
of
other
people
that
are
on
the
IAB
as
well.
We
are
fairly
open
in
our
communication.
B
B
We
have
adopted
another
one
recently
about
IAB
privacy,
partitioning,
which
is
an
interesting
document,
I
encourage
everybody
to
read
and
then
we're
currently
considering
one
about
data
and
minimalization
principles
and
feedback
on
that,
of
course,
is
always
welcome
as
well.
On
the
architecture
discuss
list,
there's
two
new
documents:
there
is
a
recent
report
on
the
IAB
workshop
on
the
management
techniques
for
encrypted
networks
that
just
finished.
B
So
next
up
we're
going
to
do
a
little
bit
on
technical
program.
Updates
first
off
is
the
EDP
EDM
program.
The
ieb
runs
a
number
of
programs
that
are
frequently
technical
in
nature
and
the
volatile
evolvability.
That
is
not
a
word.
I.
Can
say
deployability
and
maintainability
program
and
its
goal
is
to
really
you
know,
explore
and
promote
best
practices
in
protocol
design,
interoperability
and
maintenance,
and
it
actually
produced
the
IAB
protocol
maintenance
document,
which
I
talked
about
a
second
ago.
B
We
held
a
meeting
Wednesday
morning
of
this
week
talking
about
greasing,
which
is
one
of
the
ietf
or
IAB
documents
from
a
while
ago,
and
there
is
a
discussion
going
on
in
GitHub
as
well
and
there's
a
mailing
list.
We
encourage
anybody
that
wants
to
participate
in
the
discussion
to
please
join
the
mailing
list.
B
Liaison
updates
we,
as
I
mentioned
before
the
ieb,
is
responsible
for
managing
Liaisons
to
and
from
other
standards
organizations.
We
have
a
general
update
on
the
BBF.
Dave
is
going
to
talk
about
that
a
little
bit
later
and
then
a
couple
other
recent
appointments,
Charles
eckel
was
appointed
as
the
ietf
liaison
manager
to
3gpp
as
Gonzalo
stepped
down.
We
thank
him
for
his
service
and
genos
Farkas
I'm,
sorry,
probably
I'm
butchering
your
name
was
appointed
as
the
ITF
liaison
manager
to
IEEE
802
dot.
B
Ss11
I
thought
it
was
step,
one
that
one
yep
mine
and
we
thank
Eric
for
his
past
Service
as
well,
and
then
we
had
a
rather
Lively.
We
held
our
first
liaison
office
hours
today
at
lunch,
all
I
did
was
talk
for
an
hour
and
a
half
and
we
skipped
lunch,
but
it
was.
It
was
a
fantastic
set
of
discussions,
so
we
were
pretty
much
committed
to
holding
those
I
think,
probably
at
every
ATF.
Now,
because
it
was
such
a
lively
and
helpful
discussion
and
one.
B
B
So
that
was
the
welcome
and
status
update
by
mostly
me,
because
somebody
else
is
tired
and
we're
going
to
turn
it
over
next
to
the
bvf
liaison
update
to
hear
what
that
body
is
doing
and
then
we'll
go
into
energy
and
productivity,
a
presentation
about
Hiroshi
from
the
University
of
Tokyo
and
then
we'll
also
have
a
discussion
about
the
e-impact
workshop
by
Yari
and
then
we'll
have
Open
Mic
at
the
end
for
any
feedback
that
you
guys
want
to
give
us.
But
in
the
meantime,
I'll
turn
it
over
to
Dave.
D
D
So
this
kind
of
gives
you
a
feel
for
the
combined
history
that
the
group
now
has,
and
so
you
you
would
not
naturally
start
to
see
some
of
the
interest
levels
and
some
of
the
work
going
on
here
I
mean
the
the
from
the
frame
really
mpls
ATM,
there's
been
a
lot
of
mpls
related
Pals,
peewee3,
related
interest
from
the
DSL
Forum,
obviously
of
ancp,
disaggregated
or
Broadband
Network
gateways
kind
of
stuff,
and
also
the
residential
Gateway
work
that
goes
on
here.
Okay,
go
ahead,
so
the
relationship
itself
is
very
informal.
D
The
two
things
that
I'm
going
to
stress
most
is
informal
and
lightweight.
There
is
no
written
relationship.
There
is
no
need
to
have
a
written
relationship.
Basically,
the
relationship
is
managed
between
the
actual
Liaisons
that
are
exchanged
between
the
two
groups:
coordination
between
Mutual
participants
of
the
two
groups,
Yours
Truly,
the
liaison
manager
to
the
BBF
and
the
baf
liaison
officer,
which
I'll
come
back
to
so
again,
it's
light,
it's
easy
and
it's
been
working
for
quite
a
long
time.
D
D
The
members
are
companies
and
as
a
membership,
Court
Consortium,
it
actually
has
a
confidentiality
cause
on
its
membership
agreement,
which
means
all
the
work
in
progress
is
kept
confidential
to
its
membership.
What
that
means
to
the
ietf
is
that
there
should
be
no
work
in
progress
of
the
BBF
just
shared
or
distributed
around
the
ietf
unless
it
came
from
a
liaison
from
the
BBF.
D
D
Okay,
then
the
coordination
itself.
There
are
no
teleconferences
I,
I
kind
of
stole
these
slides
from
Russ
Housley.
Who
did
the
IEEE
coordination?
We
don't
have
teleconferences
except
on
rare
occasions.
All
the
coordination
is
just
inter-organizational
engagement,
it's
done
by
emails,
mostly
or
face-to-face
interactions.
At
the
meetings
either
this
meeting
at
ietf
or
the
BBF
meetings
on
a
rare
occasion,
there
will
be
a
phone
call,
it's
usually
between
a
couple
of
area
directors
and
maybe
the
what
used
to
be
the
IAB
Shepherd.
D
Now
it
would
be
the
coordinator
and
myself
and
the
interested
parties
that
are
involved
in
the
actual
topic
and
to
quote
Russ's
slide.
Historically,
you
know
the
work
of
the
coordination
has
fallen
on
the
individuals
attending
the
meetings,
it's
exactly
what
we
do
between
the
BBF
and
the
ietf,
okay,
okay.
So
the
statements
and
the
managers,
the
liaison
managers,
of
course
I
just
mentioned
I'm,
the
liaison
manager
between
the
IHF
and
the
BBF.
D
It
also
happened
to
be
the
liaison
officer
from
between
the
BBF
and
the
ietf.
So
I
talk
to
myself
a
lot
seriously.
I
mean
it's
bi-directional
and
it's
pretty
lightweight.
It's
easy
to
coordinate
between
the
two
rolls,
because
I
just
switch
brain
sides-
and
one
thing
I
need
to
stress,
though,
is
that
no
matter
which
side
I'm,
representing
it's
fair
right,
there's
no
bias
here.
D
So
generally,
a
lot
of
the
topics
and
issues
come
down
to
process
and
I'm
very
familiar
with
both
groups
and
the
process
on
both
sides
and
try
to
stick
to
very
set
of
you
know
what
I
would
call
a
mantra.
So
if
you're,
if
you're
over
in
the
BBF
you'll
hear
me
say
if
people
want
to
change
an
IHF
protocol,
you
know
the
Mantra
is
no.
D
D
D
D
Anything
you
hear
people
say
about
the
BBF
on
behalf
of
the
BBF
must
be
supported
by
a
written
liaison.
If
it's
not
it's
a
figment
of
their
imagination,
I
mean
so
seriously.
If
it's
not,
it
may
not
be
credible
and
it
needs
to
be
validated
and
the
only
way
to
validate
it
is
to
come.
Talk
to
Yours,
Truly
and
I
will
make
a
determination,
usually
there'll,
be
some
liaison
and
process,
and
it's
fine.
Sometimes
this
happens
inadvertently.
D
Sometimes
not,
but
it's
really
important
I
mean
there's
been
issues
in
the
past,
where
folks
have
made
us
assertions
in
the
middle
of
a
working
group
meeting
about
BBF,
taking
a
direction
to
justify
support
of
a
draft
or
adoption
of
a
draft,
and
you
just
there
was
some
confusion
there.
Let
me
just
leave
it
that
way.
D
Okay,
we
have
naming
and
numbering
I,
put
a
link
in
the
slides.
You
can
click
that
if
you
want,
but
there's
a
spiffy
brand
new
name
and
numbering
page
and
numbering
Authority
for
BBF
and
when
it
comes
to
the
Registries
for
the
protocols,
there's
just
a
couple
of
very
simple
rules
that
we
try
to
follow.
You
know
when
bbf's
making
a
reference
to
Ayanna.
They
should
be
checked
prior
to
going
to
final
ballot.
That's
the
BBF
process
when
the
IHF
makes
a
document
makes
a
reference
to
a
BBF
registry.
E
D
This
is
kind
of
the
meat
of
the
situation
of
where
we
are
right
now.
This
is
a
snapshot,
so
the
work
that's
of
mutual
interest
today
this
could
change
tomorrow,
but
today
it's
around
and
I've
used
the
BBF
titles
for
this
work,
but
you'll
see
analogous
titles
in
like
aippm
working
group.
So
it's
the
IP
capacity
metrics
and
measurement
work,
that's
driven
largely
by
Al
Martin.
D
D
There's
work
on
what
BBF
calls
common
Yang.
It's
basically
Yang
models
that
are
common
across
all
of
the
architectures
and
work
that
they
do
and
that's
coordinated
with
netmod
and
the
Ops
area.
We
actually
for
a
long
time
had
a
gentleman
that
we
we,
the
BBF,
had
a
gentleman
that
would
come
and
work
very
hand
in
hand
with
the
hand,
doctors
and
is
very
knowledgeable
in
Yang
and
and
the
BBF
has
adopted
many
of
the
same
practices
the
ietf
has
adopted.
D
So,
for
all
practical
purposes,
he's
kind
of
a
proxy
Yang
doctor
the
work
is
and
BBF
also
deals
has
a
lot
to
do
with
stamp
and
we've
got
Mutual
participation
on
both
sides.
There
there's
some
work
on
disaggregated
broadband,
Network
gateways
or
dbngs,
so
basically
taking
your
Broadband
Network
Gateway
and
splitting
it
apart
into
control,
playing
user
playing
and
there's
some
protocol
implications
there.
That
could
come
back
to
ietf
on
control.
D
E
E
D
You
tell
me
okay,
well,
they're
still
using
it,
it
didn't
go
away
and
there's
other.
This
is
not
an
exhaustive
list.
There's
other
work,
but
this
these
are
the
top
of
Mind
ones
that
they're
working
on
right
now,
they're
working
with
right
now,
by
the
way
the
mptcp
thing
is
coming
back
so
okay.
So
in
summary,
we've
got
a
good
working
relationship,
it's
decades
old
and
it's
informal
communication
between
leaders
and
participants.
D
D
Most
folks
know
me
as
the
liaison
manager
officer
and
we
identify
potential
areas
of
conflict
really
early
and
take
care
of
them
as
fast
as
we
can,
and
the
two
things
that
I
need
to
stress
is
one
watch
for
any
work
in
progress.
That's
not
anchored
by
a
liaison
and
if
you
hear
any
claims
about
BBF
worker
interest,
not
supported
by
a
liaison.
Let
me
know
about
that
too,
and
that's.
G
G
G
Thank
you
a
whole
lot
for
Two
Plus
Decades
of
service
here
I
was
always
really
impressed
with
how
this
relationship
worked.
It's
it's
happy,
I'm,
really
happy
to
see
it
going
on.
Have
you
thought
about
who
the
new
Dave
is
because
I
I'm
not
sure
you
want
to
do
this
for
another
40
years?
I
mean
I.
Think
we'd
be
happy
with
that,
but.
D
D
B
Speaking
with
my
liaison
coordinator
hat
on,
we
are
always
looking
for
names
of
follow-on,
so
that,
if
anybody,
you
know,
is
interested
in
liaisoning
with
any
other
organization,
we're
always
looking
for
backups
and
extra
people
to
help.
That
was
a
good
hour
of
today's
hour-long
hour
and
a
half
long
conversation
at
the
liaison
coordinator
office
hours.
So.
D
B
E
Yeah:
okay:
next
we
have
Hiroshi
presenting
us
a
little
bit:
I
I
the
local
view
on
some
energy
topics,
because
what
we're
planning
to
do
is
have
a
little
bit
of
a
discussion
about
this
topic
as
a
follow-up
from
the
workshop
we
had
last
December,
so
we're
gonna
have
we're
actually
presenting
first
and
then
we
get
Yari
with
the
update
from
the
workshop,
and
then
we
have
a
discussion
at
the
end
of
these
two
presentations
go
ahead.
Thank.
F
You
this
is
okay
from
the
wild
project.
Thank
you
for
coming
for
the
Japan
Yokohama
again
other
services,
welcome
for
you,
I'm
gonna,
I'm
gonna,
talking
about
the
current
research
and
development
series
of
the
energy
issue,
plus
the
internet
core,
especially
the
public
core
of
the
internet,
contribution
to
the
Future
Energy
System
I
want
to
talk
about
next,
please.
F
This
is
actually
the
conclusion
of
my
talk.
Our
territory
is
probably
core
of
the
internet.
I.
Believe
then,
the
hardware
infrastructure
system,
architecture,
public,
core
internet,
Plus,
modern
Computing
platform
and
digitized
functions
shall
dynamically
change.
Local
and
Global
infrastructure,
structural
topology
of
the
power
consuming
Network.
That's
a
huge
triggered
by
the
carbon
neutral
requirement
and
also
important
feature
of
the
architecture,
is
interoperability
and
data,
transparency
to
everyone
and
everything
can
deliver
the
four
goals
benefit
simultaneously
by
single
platform.
F
F
So
this
is
the
what
I
want
to
cover
today
decrease
our
area
is
by
ID
I
mean
there
is
no,
you
know,
semiconductor
business
or
data
center
implementation.
There
are
a
lot
of
work,
implementation
thing
that
we
working
of
the
network
so
how
the
network
is
going
to
contribute
that
contribute
to
the
as
is
system
and
go
to
the
2B.
F
When
you
have
the
digital
Trend,
that
was
a
12
years
ago.
I
worked
with
the
power
saving
business
against
the
serious
tsunami
in
Japan
12
years
ago,
then
digital
twin
contribute
those
huge
number
of
the
contributions
and
energy
saving
by
the
multi-bender
sustainability
by
tcpip
and
the
global
standard
for
interoperability
for
the
future
facility.
F
That
Network,
that's
very
obvious.
Next
phrase,
though
an
important
thing,
I've
learned
or
I
I've
learned
from
that
experiences
are
important.
Role
to
passive.
The
power
network
is
determined
by
Peak
power.
Demand
reduction
of
demand
at
Peak
time
contribute
to
the
reduction
of
the
huge
cost
of
the
capacity
for
power
of
a
supply
net
Network
for
the
power
distribution
net
Network.
F
That
is
huge
contribution
by
the
internet,
based
control
system
against
the
demand
changing
in
the
user
side.
Next,
please
so,
and
also
those
areas,
especially
iot
people
really
hate
it
TCP
internet,
they
love
isolated.
They
don't
want
to
cooperate
to
together
and
also
at
the
time
they
have
a
very
bad
communication
infrastructure.
Therefore,
12
years
ago,
we
worked
on
the
dtn
that
the
completed
difference
from
existing
broadband
internet
always
connected
with
a
high
quality,
though
those
industry
doesn't
have
such
a
quality.
So
we
worked
on
the
dtn
at
the
time.
Experience.
F
F
So
this
is
the
architecture
we
built
at
the
our
campus
facility
system.
Basically,
the
Legacy
system
doesn't
have
any
Global
connectivity,
so
we're
providing
the
you
know:
LOD
function
to
every
single
devices
which
was
not
connected
to
the
internet
and
also
independency
from
hardware
for
our
poor
applications.
That
is
the
you
know.
Modern
cloud
computing
is
now
doing
similar
signal
apply
to
those
Legacy
or
city
Network.
Next,
please.
F
So
this
is
the
used
to
be
Legacy
system
has
there's
four
kpi
new
function,
energy.
You
know
productivity,
Improvement,
carbon
neutral
and
security
for
bbcp.
All
of
those
they
have
isolated
implementation
for
each
kpi.
So
what
the
function
of
the
internet
or
internet-based
energy
system
is
clickbase.
F
Based
on
the
open
platform,
all
of
those
four
perspective
or
kpi
can
be
conjunctioned
with
by
the
single
infrastructure.
Express
then,
multiple
payoff
by
the
economy,
ecosystem
by
the
sharing
economy
going
to
be
done
in
power,
consuming
system
quite
similar
to
the
internet
infrastructure.
We
have
next,
please
so
that
is,
as
is
system
the
contribution
of
the
internet.
To
that
next
one
is
the
2B
that
is
the
Cyber
first
implementation
for
the
energy
system
from
400
review
next
piece.
F
About
200
years
ago
we
have
very
exclusive
separated,
Logistics
per
merchandise,
human
being
invented,
container
and
parrot
in
the
logistics.
Then
we
have
physical
sharing
economy.
Apparently
you
enjoy
the
thing
right.
Every
single
package
be
able
to
use,
shape,
train
car
or
ship
everything
be
able
to
carry
it
by
the
common
package.
F
F
F
That's
more!
That's!
The
two
two
digit
difference
has
been
recognized
by
everyone:
the
huge
energy
productivity,
Improvement
gonna
down
replacing
physical
transportation
to
digital
that
we
already
realized
that
that
is
quite
important.
Contribution
by
the
public
core
internet
I.
Believe
next,
please.
F
So
this
is
a
real,
very
simple
equation:
transfer
or
mobility
cost
that
is
related
to
the
energy
productivity,
electricity
versus
station
bits
about
100
times
different,
which
means
huge
infrastructure
redesign.
We
can
do
with
a
database
transmission
system
next,
please
so
this
is
again.
The
speed
of

is
not
fast.

100
viewer
energy
in
those
countries,
and
also
there
are
a
lot
of
non-real-time

that
is
very,
very
different
from
the
existing.
You
know,
UI

of

wanted
the
nearby

that
that
is
changing

That
does
not
require

We
have
so
we
could
change
so
when
we
think
about
global
scale.
F
F
F
You
know
a
hot

with
a
very
cool

so
that
is
one
of
the
important
infrastructure

We

work
in
public

of
the

the
internet
consuming
a
lot
of
energy
now
with
the

So
when
we,
you
know
efficiently
or
strategically
use
those

existing

be
able
to
change
a
lot
and
also
easy
to
change

Thank
you.
E
Yeah
thanks
a
lot.
That's
a
really
nice
insight
and
some
really
nice
examples
how
the
internet
can
help
to
save
energy
and
some
thoughts
you
you
can
sit
down.
We
take
any
kind
of
discussion
after
Yaris
talk.
Thank
you
there's
already
some
discussion
going
on
in
the
chat,
but
we
have
Yari
reporting
a
little
bit
from
the
workshop,
giving
a
broad
perspective
about
what
was
discussed
at
the
workshop,
and
then
we
have
a
discussion
all
together
at
the
end.
H
Yes,
thank
you,
so
I'm
just
going
to
do
a
very,
very
brief
piece
on
the
workshop
high
level.
Hopefully
in
the
proceedings
page,
you
will
find
these
links
for
the
draft
for
the
IAB
Workshop
page
and
there's
also
a
new
list,
e-impact
iitf.org,
that
you
can
use
for
discussion
and
it's
being
used
for
discussion
next
slide,
please.
H
So
what
was
this?
This
was
a
IRB
organized
workshop
with
altogether
73
participants,
not
just
regular
ITF
participants,
but
also
research
and
a
little
bit
like
adjacent
communities
that
are
important
for
this
topic,
but
are
not
maybe
so
much
present
in
the
ITF.
Normally,
we
had
a
participation
through
submission
of
position
papers
as
it's
quite
common
for
the
IAB
workshops,
26
papers,
and
if
you
wonder
why
the
participant
number
is
higher
than
the
paper
number.
H
That's,
because
we
also
accepted
all
the
co-authors
which
were
plentiful
in
in
some
of
the
papers,
and
that
was
actually
good,
because
that
was
a
really
good
discussion
from
all
of
them
and,
of
course,
we
care
about
the
environment.
We
care
about
the
planet,
the
humankind's
destiny.
We
also
happen
to
care
about
business
things,
and-
and
this
is
one
of
those
areas
where
business
and
good
of
the
human
humankind
may
actually
be
aligned
at
this.
H
So
what
did
we
learn
so
so,
for
me,
at
least
sort
of
the
big
mind-blowing
thing
was
that
there's
so
many
things
on
under
this
particular
topic
and
that
different
people
think
in
very
different
terms.
Like
you
know,
we
are
all
experts
in
in
certain
Fields
and
we
like
to
think
about
those
fields
when
we're
doing
something,
but
other
people
are
focusing
on
very
different
things
and
actually
all
of
them
matter
for
this
particular
issue.
H
And
it's
not
the
case
that
I
don't
need
to
do
anything
because
those
guys
buying
green
energy
will
handle
it.
That's
not
the
only
thing
that
we
need
to
do.
We
need
to
also
improve
on
our
sides,
and
the
same
is
true
of
of
basically
everything.
That's
visible
on
the
on
the
screen.
So,
if
you
look
at
on
the
right
side,
there's
a
bunch
of
protocol
related
things.
H
One
example:
Michael,
Wilson
and
and
his
colleagues
looked
at
how
to
use
consistent
control,
algorithms
and
improvements
there
to
actually
also
improve
sustainability
and
reduce
energy
consumption
with
some
surprisingly
good
results,
and
you
can
look
at
other
other
things,
routing
and
so
on.
That's
been
a
popular
discussion
topic,
but
it's
not
the
only
thing
we
we
hear
design
protocols
at
the
ITF,
but
it's
like
there's
plenty
of
other
stuff
outside
the
IDF.
H
How
often
you
have
to
send
certain
types
of
messages
is
specified
in
standards,
and
if
you,
if
you
relax
those
rules,
then
you
actually
have
a
little
bit
more
room
in
the
implementations
to
shut
things
down,
put
them
to
sleep
for
a
millisecond
or
or
a
micro
second,
but
doesn't
stop
there
there's
also
tons
of
other
other
stuff.
We
can
talk
about
our
understanding
of
this
problem.
What
does
the
internet
use
and
it's
actually
a
little
bit
fussy?
It
probably
needs
more
research.
H
We
can
talk
about
metrics,
so
many
of
us
at
the
itflow
talk
about
that.
But
it's
also
even
beyond
that.
It's
about
about
like
how
do
we
use
it,
for
you
know
improving
the
electricity
production,
for
instance,
or
you
know
what
is
the
societal
impact
of
this
and
what
other
actors
there
are
in
this
space
and
the
next
slide.
H
Tourless
did
a
nice
nice
draft
on
that.
Go
read
that
his
paper
and
and
the
draft,
if
you're
interested
in
in
the
more
full
list.
And,
of
course,
these
problems
are
hugely
complicated
and,
like
there's
many
interrelations,
and
it's
also
crucial
to
understand
that
there's
many
Traders
and
constraints
like
if
you
make
it.
You
know
change
in
this
routing
thing
here.
Maybe
it
impacts
Jitter
or
you
know
some
other
feature
for
the
applications,
and
maybe
that
actually
implies
that.
H
Then
the
let's
say,
video
conferencing
doesn't
work
as
well,
and
then
you
know
I'm
gonna
travel
instead
of
use
the
video
conferencing.
So
it's
it's
sort
of
complicated
picture
and
we
do
need
to
look
at
sort
of
Beyond
protocols.
I
mentioned
the
implementations
example.
We
do
need
to
look
at
metrics
measurements
and
data
and
running
those
experiments.
Also
not
just
like
the
technology
for
the
experiments
but
actual
experiments.
We
need
a
more
Dynamic
ability
to
sleep
TVR.
H
H
We
talked
about
lots
of
other
things,
avoiding
proof
of
or
crypto
assets.
So
Matson
had
a
paper
about
that
and
we
also
had
a
chat
about
environmental
consideration,
sections
in
ITF
drafts
and
didn't
actually
conclude
that
discussion,
but
it's
an
important
bit
to
consider.
Nevertheless,
anyway,
a
quick
cluster,
a
couple
of
things
so
well.
H
Of
course,
it's
a
complicated
thing,
because
technology
can
also
change
and
can
you
shut
down
parts
of
your
device,
even
if,
if
you
have
a
lot
of
capacity
next
slide,
sures
and
Carlos
talked
about
how
we
actually
need
to
optimize,
not
just
for
a
throughput,
but
also
about
a
bunch
of
other
parameters,
including
Energy
Efficiency,
and
we
might
be
going
like
first
step.
Is
visibility
but,
ultimately
you
might
want
to
end
up
in
a
state
where
you
have
some
kind
of
automatic
self-optimization
next
slide
and
one
one
more.
H
One
more
example
is
about
data
format,
so
this
was
an
example
done
specifically
about
Cinema
in
iot
systems
and
where
you
can
have
a
choice
between
Json
versus
seabor,
and
you
know,
not,
surprisingly,
you
actually
use
less
bytes
and
less
energy
if
you
use
the
more
compact
format
and
the
so.
The
lesson
for
for
us,
I
guess,
is
that
we
should
consider
using
some
of
these
things
in
other
protocols
as
well
like
HTTP,
2.
H
I
guess
is
binary
format
compared
to
some
of
the
other
previous
versions,
but
but
that
for
new
protocols.
This
is
a
thing
to
to
potentially
consider
and
I.
Think
I'm
done,
I
guess,
at
least
from
my
perspective.
The
interesting
thing
for
for
this
room
to
discuss
is
what
can
the
ITF
do
and
what
are
the
immediate,
short-term
next
steps?
That
would
be
most
worthwhile
for
us
to
move
forward
on
this
and
there's
no
Silver
Bullet,
but
we
can
make
an
impact
every
year,
then
that
would
be
good.
B
Right,
thank
you
very
much
Jerry
and
thank
you
to
both
of
our
speakers
for
the
energy
related
topics
tonight
we
would
like
to
take
any
comments
or
questions
related
to
either
of
the
two
topics.
If
you
want
to
put
your
name
in
the
queue
and
come
to
the
microphone,
I
think
that
you
know
this
is
certainly
an
area
where
the
IHF
can
use
a
lot
of
discussion.
G
G
G
Right
like
so
you
know,
maybe
you
don't
want
to
create
a
whole
bunch
of
E-Waste
with
the
the
upgrade
cycle
that
is
implied
by
by
the
growth
of
protocols
and
the
growth
of
code,
et
cetera,
et
cetera,
et
cetera,
right,
we're,
adding
another
set
of
Dimensions
to
optimize.
For
and
that's
why?
I
think.
One
of
the
things
that
I
saw
in
the
the
workshop
report
is
lots
of
questions,
lots
of
sort
of
like
expansion
of
the
problem,
space
and
I.
G
Think
that's
the
phase
that
we're
in
right
now
I
think
that's
really
good,
not
really
much
in
terms
of
contraction
right
like
so.
It's
like
we're
getting
to
terms
of
how
much
bigger
this
makes
the
problem
space
so
I
definitely
think
that
this
is
something
that
the
the
ITF
should
be
considering
with
respect
to
protocol
development.
Right
like
this
is
a
this
is
an
important,
important
knob
that
we
can
give
people
who
deploy
our
protocols.
G
I
I,
don't
know
that
that's
gonna,
be
anything
other
than
like
a
talking
and
coming
to
terms
with
the
problem
thing
for
a
little
while
and
that's
probably
okay,
so
I
think
what
I'm
asking
for
is
an
IEP
program
in
this
space,
but
I'm
not
sure
yet
so
I'll
I'll,
let
Rich
pontificate
for
a
bit
on
that.
I.
Think
that
that's
I
think
that
we
need
a
place
to
talk
about
this
and
a
place
to
continue
talking
about
this,
and
it
sounds
like
Yari
has
an
opinion.
H
H
H
C
F
Hello,
this
is
your
sake.
The
reason
why
I
didn't
touch
on
the
particular
concrete
technology
you
find
where
the
idea
was.
Basically
the
architecture
concept
of
the
internet
is
quite
important,
applied
to
the
energy
industry
or
energy
infrastructure,
then
the
very
better
large-scale
you
know,
autonomous
infrastructure.
The
core
part
of
the
internet
is
important
in
order
to
help
their
Innovation
their
Innovation.
F
B
I
F
D
I
J
Going
around
the
long
way,
Pete
Resnick
just
to
kind
of
air
what
was
said
in
the
chat
room
as
Hiroshi
was
presenting
I
thought
well
now,
yeah
3D
printing
is
probably
a
lot
cheaper.
You
know
remotely
than
you
know,
moving
the
things
around
but
boy.
What
are
the
implications
of
moving
the
raw
materials
to
do
that,
3D,
printing
and
and
do
we
does
that
mean
that
mining
is
going
to
happen
in
interesting
places
that
might
be
more
expensive
either
monetarily
energy-wise
societally
and
then
I'm?
J
Looking
at
this,
that
Brian
had
you
put
up
and
I
thought.
Oh
those
sure
look
like
knobs
to
turn
where
turning
the
Energy
Efficiency
knob
might
change
the
latency
and
throughput
knobs.
A
lot
and
I
just
feel
like
the
calculations
here,
get
really
interesting
and
complicated,
really
fast,
I
always
love
the
example
of
maybe
the
highest
throughput
is
taking
a
bunch
of
thumb
drives
and
and
putting
them
in
the
back
of
a
truck
and
moving
them
across
town,
so
yeah.
It
seems
really
hard
to
calculate
this.
H
I'm
sure
it
is
super
hard,
just
like
one
sort
of
optimistic
view
on
this,
like
that,
it's
not
the
case
that
we
always
degrade
the
other
parameters
by
you
know
making
the
Energy
Efficiency
better.
It
can
actually
be
a
win-win
in
in
some
cases
at
least
and
certainly
been
through,
like
you
know,
you
introduce
new
technology
and
who,
suddenly
you
are
faster
and
more
energy.
Conservative.
F
Also,
the
reason
why
I
try
to
separate
computation
is
that
kind
of
simulation
or
evaluation
is
quite
important,
that
that's
not
the
network
issue,
basically
right
based
on
such
a
result,
I
we
want
to
optimize
the
net
Network
and
also
regarding
3D
printers.
You
know
abuse
thing.
We
really
need
those
kind
of
what
kind
of
abnormal
use
I'm
gonna
do,
that
is
our
business.
K
Hey
David
here
has
there
been
any
analysis
done
on
the
ROI,
based
on
like
the
different
phases,
the
life
cycle
or
supply
chain,
because
you're
talking
about
like
having
iib
scope
out
some
work
and
hand
it
over
to
the
iitf?
But
then
still,
if
you
look
at
the
whole
supply
chain,
it's
not
just
the
ITF,
it's
you're
gonna
you're,
talking
about
how
vendors
are
manufacturing
things,
what
materials
they're
using
now.
K
Of
course
the
protocols
could
expose
those
things
and
then
there's
some
work
that
ITF
could
do,
but
still
there's
like
some
coordination,
you
can
say
like
okay.
This
is
how
much
benefit
ITF
could
bring
about
through
protocol
work,
but
that's
just
let's
say
like
20
of
the
slice
of
the
pie
and
we
need
collaboration
with
other
standards,
bodies
or
other
vendors
bodies
in
order
to
achieve
the
remaining
80
of
the
whole
life
cycle,
any
kind
of
like
now.
It's
just
been
done.
There.
H
A
real
quick
answer:
I
I,
don't
think,
there's
a
full
analysis
anywhere,
but
it
you
know,
things
of
this
nature
have
been
brought
out.
Large
cigarette,
for
instance,
brought
up
in
the
side
meeting
that
someone
has
to
be
careful,
that
the
embedded
cost
in
equipment
and
so
on
doesn't
come
much
larger
because
we
keep
replacing
the
the
system
components
all
the
time,
because
we
have
supposedly
improved
Energy
Efficiency.
So
there
are
a
lot
lots
of
trade-offs
and
connections
here.
F
C
I'll
just
make
a
quick
comment
like
so
like
to
Rich's
Point,
there's
like
a
whole
set
of
trade-offs
in
this
space
right
like
so
so,
for
example,
like
multicast,
came
up
with
something
that
can
save
energy,
but
like
then,
this
other
set
of
people
for
whom
multicast
really
waste
a
lot
of
energy.
So
this
is
like
there's
no
easy
answer
here
so
same
for
like
David's
point
right
and
Pete's
Point
as
well.
C
So
like
this
thing
is
like
a
whole
bunch
of
trade-offs
and
one
of
her
goals
might
be
to
just
like
document
such
trade-offs
in
some
place,
and
so
that's
kind
of
a
necessary
condition
for
the
sustainability
consideration
section.
So
how
can
we
help
people
look
at
the
sustainability
costs
or
the
decisions
they
are
making
and
if
you
look
at
the
papers,
David
like
specifically
there's
like
some
that
talk
about
how
we
can
have
like
something:
that's
less
optimized
for
today,
but
has
a
longer
lifetime
so
or
the
lifetime.
