A
A
Welcome
to
the
I
RTF
overview,
let
me
know
if
you
can
hear
me
in
the
back:
okay
good
over
the
years,
I've
managed
to
get
a
lower
voice,
so
okay,
so
this
is
the
first
time
we've
given
this
and
I
will
be
happy
to
give
Clark
to
answer
clarifying
questions
along
the
way.
If
you
have
any
and
I
warn,
you
now
have
a
lot
of
silly
pictures,
so
so,
first
of
all,
you'll
start.
A
You
probably
have
seen
this
already,
but
you'll
start
to
see
this
if
you're
new
here,
which
is
the
note
well-
and
the
important
thing-
is
that
the
I
RTF
follows
the
ITF
intellectual
property
rights
rules.
So
here
is
your
note
well
for
this
I.
Don't
think
we
have
discussion
in
here.
Necessarily
that
applies,
but
if
we
do
well
under
the
night,
then
note
well
I
mean
I.
Think
any
IETF
based
discussion
is
under
the
note.
Well
and
I'll
talk
some
more
about
how
that
came
to
be
and
some
of
the
history.
A
A
So
if
you
hear
anything,
you
like
we're
having
a
meeting
this
week,
and
so
please
check
these
meetings
out
lots
going
on
and
I'm
going
to
talk
about
each
of
these
groups
of,
but
the
established
groups,
a
proposed
group,
the
the
panel
G
and
an
initial
organizing
meeting
for
a
group
called
din
are
all
taking
place
so
yeh
right,
IRT,
F,
Festival,
the
origins
of
the
ITF
is
the
first
topic
and
it
goes
back
a
long
way.
Actually
the
IRT
F.
A
As
you
probably
know,
the
internet
started
from
research
projects
and
so
early
on
there
was
a
fairly
close
tie
between
research
and
engineering,
but
in
the
beginning
there
was
a
set
of
task
forces.
I'm
calling
this
the
task
force
era
and
instead
of
the
prehistoric
era,
but
this
was
starting
about
1984,
so
in
the
very
very
earliest
days
of
the
internet.
A
There's
a
great
historical
efforts
to
all
this
on
IAB
org.
If
you
want
to
read
more
about
it,
there
were
many
task
forces
at
the
beginning.
The
IETF
was
one
of
them.
There
were
also
a
privacy
and
security
task
force,
an
autonomous
systems,
task
force
that
was
headed
by
Deborah
Estrin,
with
just
the
origin
of
some
of
her
very
earliest
routing
ideas.
Many
of
them
in
1989.
There
was
a
big
reorg
to
kind
of
make
these
groups
more
functional,
as
people
realize
that
we
will
have
more
than
just
researchers
involved
and
we
got
the
IETF.
A
Would
you
you
know
about
I
believe
the
end-to-end
task
force,
which
was
a
holdout
for
a
long
time
that
covered
things
like
transport?
It
was
the
origin
of
some
of
the
quality
of
service
RSVP,
a
bunch
of
things.
It
was
a
place
where
a
lot
of
the
early
internet
media
took
place,
the
IAB
and
the
IRT
F.
A
We
have
some
rfcs.
If
you
want
to
read
about
how
things
work
in
the
IOT
f,
the
earliest
one
is
RFC
2014,
which
is
way
back
there.
It's
as
early
as
the
original,
the
formation
of
the
IRT
F.
The
IAB
eventually
took
on
the
role
of
structuring
the
IRT
F
to
some
extent
and
there's
an
IAB
RFC
RFC,
four,
four,
four
zero.
That
covers
what
the
role
the
iltf
does.
There's
a
document
for
publishing
to
describing
how
we
do
RFC
is
for
the
IRT
F
Spencer,
you
know,
I,
don't
think
I
have
your
RFC
here.
A
So
I
actually
should
have
had
that
here.
I
clipped
this
from
our
website.
Do
you
do
so
look
up
Spencer,
Dawkins
document
as
well,
which
will
give
you
a
lot
of
the
nice
cultural
background
of
the
IRT,
F
and
I
will
add
it
to
the
slides.
As
I
mentioned,
we
follow
the
note
well
and
also
the
IRT.
F
follows
the
anti-harassment
policies
that
ITF
has
developed
and
I'm
actually
on
the
Ombuds
team.
So
we
have
a
built-in
Ombudsperson
in
the
IRT
F
leadership.
A
The
mission,
basically,
is
that
eventually
we
realized
that
there
was
long
term
and
short
term
research
or
long
term
and
short
term
development
and
IOT
F
is
the
home
of
the
longer
term
work
and
the
ITF,
and
we
review,
as
as
I
said
as
a
parallel
organization
to
the
IETF
and
so
I.
Our
tip
does
not
produce
standards,
it
doesn't
produce
any.
It
produces.
Experimental,
sometimes
and
informational
doesn't
always
produce
documents
and
we
created
it
as
a
a
group
of
research
groups.
A
So,
just
like
the
ITF
has
working
groups,
the
IRT
F
has
research
groups,
so
that's
kind
of
the
mission
and
the
overview
of
the
of
the
structure.
So
the
relationships
it's
complicated
to
understand
the
relationships
of
the
IRT
F,
our
parent.
Now,
although
it
wasn't
always
our
parent
is
the
IAB
and
I'll
talk
some
more
about
the
details
of
that
relationship.
In
a
moment,
the
Internet
Society
is
also
a
partner
of
the
IRT
F
and
I'm,
going
to
talk
about
several
programs
that
we
have
that
are
close
connections
with
I
sock.
A
A
We
also
follow
some
of
the
other
policies
and
we
follow
the
stream
rules
and
so
on
with
the
same
RFC
editor
but
and
I'm
going
to
talk
about
research
groups
and
their
roles,
they
may
have
roles
in
relation
to
existing
working
groups.
So
the
idea
here
is
that
by
attracting
say
a
bunch
of
crypto
experts
to
the
crypto
forum.
We
actually
provide
a
forum
where
ITF
groups
can
go
and
say.
Could
you
solve
this
problem?
Could
you
make
a
decision?
A
For
me
an
example
of
this
is
that
the
crypto
forum
did
some
work
on
helping
to
determine
what
curve
you
know
what
elliptic
curves
would
be
the
one
that
should
be
standardized
in
TLS
and
then
also
research
groups,
as
you
might
expect,
as
they
work
long
term.
Eventually,
they
may
produce
a
spin-off
group
that
becomes
an
IETF
working
group.
So
that's
another
tight
relationship
between
the
IRT
F
and
the
IETF,
and
when
I
talk
about
some
of
the
groups,
I'll
talk
about
that
more
details
of
the
IAB
relationship.
A
First,
so
the
IHF
chair
is
appointed
by
the
the
architecture
board,
so
they
have
a
process
for
doing
that.
The
IRT
F
chair
becomes
a
member
of
the
IAB
ex
officio.
That
means
that
I
don't
vote
but
because
otherwise
I'd
be
voting
on.
Who
is
the
next
IRT
F
chair,
but
I
do
actually
participate
in
all
the
IAB
activities.
The
IRT
F
chair
does
that,
and
that
makes
sense,
because
the
IAB
looks
looks
after
long
term,
architectural
considerations
and
then
internet
architecture
board
is
the
one
that
manages
the
RFC
editor
functions
and
the
RFC
strips.
A
So
when
we
make
a
decision
about
how
ia
be
how
I
RTF
is
going
to
publish
our
work,
the
IAB
is
closely
involved
with
that.
So
we
have
lots
of
eyes
there.
We
sometimes
for
those
of
you
who
are
new
to
the
ITF.
We
sometimes
call
this
the
I
star,
all
the
different
things
that
start
with
I
and
people
appropriate
that
for
other
work,
other
uses,
but
I
believe
it
was
originated
here
when
we
got
all
these
eyes,
the
IETF,
the
IAB,
the
IRT,
the
ISG
of
the
IRS
G.
A
Okay,
I
have
only
been
the
IRT
F
chair
since
March
my
predecessor
was
was
Eggert,
who
is
a1,
was
a
wonderful
IRT,
F
chair
and
he
presided
over
the
iit
F
from
2011
to
to
March
and
I've,
been
very
happy
to
follow
him
in
this
role,
because
he
did
some
great
things
for
the
IRT,
F
and
I
wanted
to
specifically
mention
him
in
that
picture,
he's
wearing
his
honorary
tie-dyed
lab
coat,
which
was
given
to
him
as
a
parting
gift
by
the
I
star
to
say
goodbye
to
him,
but
he
created
two
programs,
the
applied
networking
research
prize
and
the
applied
networking
research
workshop
that
I'm
going
to
talk
about
which
have
been
a
very
successful
way
for
the
IRT
F
to
connect
to
the
rest
of
the
world.
A
So
those
are
the
a
start,
and
he
also
did
a
great
thing.
Easing
the
path
easing
the
way
that
we
create
research
groups
and
I'll
talk
about
that.
So
I
look
for
lookup
to
laws
and
I
wanted
you
to
know
about
him.
He
he's
around
he's
actually
co-chairing
the
quick
working
group
and
he's
still
participating.
The
is
G
so
say
hello
to
him
and
tell
him
that
he
was
a
very
good
IOT
F
chair.
If
you
see
him
okay,
he
probably
won't
be
wearing
that
lab
coat,
though
so.
A
Can
give
a
sense
of
the
ITF
and
then
the
IRT,
F
and
think
about
coming
to
work
with
us
there
and
the
clever
thing
about
this
is
that
it's
based
on
previously
published
papers.
So
we
put
out
a
solicitation
saying:
have
you
published
a
paper
where
networking
is
covered
but
where
there's
applicability
to
real
world
problems,
I
mean
there's
a
lot
of
theoretical
networking
papers.
We
would
tend
not
to
take
those
and
an
existing
paper
can
be
awarded
and
the
person
who
submits
it
also
makes
a
case
for
a
speaker.
A
So
it's
usually
one
of
the
younger
primary
authors,
typically
someone
who
is
either
a
grad
student
or
a
recently
graduated
recent
PhD
I,
believe
our
speakers
are
here
in
the
audience
today,
because
I
asked
them
if
they
would
come
and
we
will
have
a
meeting
where
we
feature
the
speakers
for
each
IETF.
So
we've
had
we
had
different
speakers
in
March
in
on
Thursday
at
the
IRT
F
open
meeting,
they
have
Stephen
check
or
a
who's
going
to
talk
about
a
security
incident
with
dual
EC.
So
it's
as
a
very
interesting
paper
Stephen.
A
Do
you
want
to
raise
your
head,
so
please
come
to
that
it's
these
are
great
discussions
and
we
really
love
one
of
the
things
that's
also
nice
about
this
is
that
IT
efforts
tend
to
ask
very
incisive
questions.
So
there's
a
lively
discussion
when
we
have
these
and
then
the
other
is
Phillip
Richter
who's
going
to
talk
about
carrier-grade,
not
deployment
measurements
at
Phillip.
Are
you
in
the
audience
too?
Yes,
hi,
okay,
so
come
and
hear
these
great
speakers
join
us
for
this
with
this
prize.
A
We
really
enjoy
this
if
you
have
papers
that
you've
published-
and
you
want
to
submit,
keep
your
eye
open
on
the
IRT
F
I
should
have
even
put
that
sorry,
the
IRT
F
just
mailing
lists
for
announcements,
we're
also
announcer
and
the
ietf
s
for
announcements
of
the
next
set
of
submissions.
For
that,
and
we
have
a
peer
review
committee
if
you're
interested
in
joining
that
committee,
you
could
also
talk
to
me
about
that.
A
Mercer
help
the
applied
networking
research
workshop,
which
is
once
a
year.
It's
been
typically
in
the
summers
and
you've
just
missed
it.
It
was
yesterday.
However,
you
can
read
all
the
papers
and
you
can
see
a
recording
of
it.
This
is
a
classic
research
workshop
like
is,
and
it's
co-sponsored
with
ACM
and
with
I
saw
so
it's
different
between
from
an
or
from
other
researchers.
Research
workshops
is
simply
that
it's
more
applied,
we
hope
and
that
the
audience
includes
again
these,
so
the
lively
ITF
questionnaire.
A
So
yesterday's
workshop
had
a
lot
of
great
questions,
those
of
you
or
have
it.
You
probably
know
that,
and
so
please
feel
free
to
read.
These
papers
are
a
lot
of
great
papers
and
again,
if
you
are
interested,
those
are
new
papers
not
previously
published
will
solicit
those
in
the
next
six
months
sometime
and
there's
both
long
and
short
papers.
So
we're
very
happy
to
have
more
participation
in
this
as
well.
Okay,
so
organizationally,
we
have
a
steering
group,
the
chairs
of
the
research
groups
and
then
some
people
who
are
at-large
members.
A
We
have
a
business
meeting
at
each
ITF
and
we
actually
that
was
air
quotes.
We
actually
do
business,
but
we
there's
a
tradition
that
goes
back
to
the
beginning.
You
know
that
picture
that
I
showed
you
of
the
prehistoric
days
of
having
a
lot
of
wine,
so
those
business
meetings
are
have
a
wine
budget
provided
by
different
members
and
I.
A
Guess
that
helps
for
creativity,
I
hope
the
irst
also
is
responsible
for
helping
to
advance
the
the
document.
So
the
working
group,
a
given
research
group,
will
decide
it's
ready
for
its
work
to
be
published
and
we'll
ask
the
IRS
G
to
produce
several
reviews
and
then
we'll
ask
the
members
of
the
IRS
tree
to
vote
whether
you're
not
ready
to
help
us
decide
if
it's
have
enough
for
you.
So
this
is
a
group
of
the
group,
some
of
the
members
of
the
IRS
G.
Now
the
at-large
members
are
listed
here.
A
Spencer
there
is
one
of
them,
I,
don't
know.
If
there's
any
others
in
the
room,
we
have
a
few
new
ones
and
then
the
the
chairs
of
the
RG
are
also
members.
So
it's
a
great
group,
it's
almost
as
great
as
the
Justice
Society
of
America
and
I'm,
not
particularly
favoring
America
there.
It
just
happened
to
like
those
particular
superheroes,
so
we
try
to
be
actually
we're
trying
to
actually
be
as
global
as
we
can.
A
They
one
research
group
can
do
a
number
of
these
functions.
One
of
them
is
to
be
an
incubator.
You
may
or
may
not
know
that
it's
quite
difficult
to
get
work
completed
in
the
ietf
because
of
ITF
process
because
of
the
extensive
amount
of
reviewing
because
of
the
tight
focus,
that's
required
by
the
iesg
one
of
those
I
star
on
the
work
research
groups
are
fear
to
serve
world
and
and
get
into
different
areas
to
follow
the
promising
directions,
not
completely
free
one
of
the
jobs
of
the
the
state.
A
The
at-large
members
and
myself
is
to
ask
people
to
stay
in
a
productive
role,
not
to
go
everywhere,
but
but
they
can
incubate
new
ideas.
So
that's
one
of
the
things
another
as
I
mentioned
before
is
this
expert
support
for
the
IETF.
The
CFR
G
was
the
example
I
gave
earlier
that
gives
crypto
expert
crypto
analysis
to
groups
that
need
it.
A
We
have
the
ICC
our
G,
which
is
a
congestion
control
research
group
that
takes
up
the
heart,
they're,
really
flex,
aspects
of
congestion
control
so
that
they
don't
have
to
be
done
by
all
the
different
groups
that
have
to
deal
with
congestion
control,
but
Network
coding
group
should
be
doing
this.
We
need
to
get
it
into
a
better
focus
if
any
of
you
work
on
network
coding
and
have
an
interest
in
this.
A
Let
me
know
because
we're
trying
to
we
energize
that
effort,
there's
a
lot
of
interesting
coding
work,
but
we
haven't
been
using
that
group
as
well
as
we
might.
Another
thing
is
to
identify
things
that
we're
not
doing
that
we
should
be
doing
and
to
so
give
them
some
visibility.
So
the
IETF
can
decide.
Is
this
something
that
we
should
actually
focus
on?
In
some
ways?
The
ITF
because
of
its
history,
covers
everything
in
the
ie
in
the
Internet
at
times
and
figure
out
which
things
actually
are.
A
A
good
use
of
our
time,
which
things
are
in
need
of.
The
kind
of
engineering
we
do
is
something
that
the
IRT
F
has
been
able
to
help
with
traditionally
there's
a
similar
thing
is,
is,
if
you
have
an
emerging
area,
that's
coming
out
of
academia
or
industry.
It
may
be
burgeoning,
and
some
ask
some
particular
industry,
but
is
there
a
way
that
then
I'll
be
thought
about
for
the
global
Internet?
A
So
we
expect
the
IRT
F
to
work
on
the
big
I
internet
and
to
look
at
questions
that
have
global
scope,
and
so
this
is
a
way
that
something
that's
going.
On
an
example:
that's
coming
up
is
blockchain,
so
blockchain
is
being
used
in
a
lot
of
things,
one
of
the
ways
that
it
scales
to
the
whole
internet.
What
are
the
ways
that
it
doesn't
scale?
That's
an
example
where
something
that's
happening
very
actively
in
the
outside
world.
You
might
think
why
do
we
need
to
do
this?
A
It's
because
we
have
the
expertise
to
look
at
this
global
question
and
understand
how
we
might
apply
it
in
the
way
that
would
give
it
a
different
amount
of
applicability
and
then,
as
I
mentioned
before,
future
working
groups
sometimes
come
from
research
groups.
So
one
example
was
the
reliable
multicast
research
group
which
went
on
to
form
a
RMT,
reliable,
multicast
transport
group
and
produce
several
standards
that
are
in
play
in
the
world
and
then
the
the
disruption,
tolerant
networks
which
started
out
as
interplanetary
networks
and
got
changed
to
delay-tolerant
networks.
A
An
eventually
disruption,
tolerant
and
DTN,
is
a
current
working
group
that
has
spun
off
from
a
research
group
and
those
are
our
protocols
which
can
survive
not
having
connectivity
for
a
long
time.
Let's
say
that,
with
this
interplanetary
concept,
where
you
might
not
be
able
to
get
your
signal
through
to
Mars
till
you
got
into
a
certain
orbital
situation.
But
how
do
the
protocols
actually
manage
that
situation
in
a
kind
of
consistent
way?
So
that's
a
really
great
example:
Vint
Cerf,
who
was
one
of
the
founders
of
everything
here?
A
Sorry
of
that,
and
then
it
became
a
research
group
and
then
a
working
group,
and
so
the
other
thing
looks
likes
about
research
groups,
as
I
mentioned,
is
that
they
don't
have
a
fixed
process.
They
don't
have
to
meet
here.
If
they
don't
want
to
they.
Often
some
of
the
groups
meet
other
places
more
often
than
they
meet
here,
Gaia
catch
it
while
you
can,
because
it
is,
it
very
rarely
meets
at
the
IETF.
I'll
describe
them
in
a
few
minutes
and
they
can
also
use
whatever
strategies
they
like
for
actually
having
a
good
discussion.
A
So
they
don't
have
to
be
kind
of
presentations
a
or
issue
resolving.
They
can
do
it
whatever
way
works
best
for
their
group.
Okay,
let's
go
into
the
particular
working
groups.
Now
I
found
a
lot
of
science
fiction
pictures
on
archive.org.
So
that's
what
you're
getting
this
time.
I
like
science
fiction
a
lot.
So
the
first
is
the
crypto
forum,
their
chairs
of
that
are
listed
here.
Unfortunately,
I
put
an
extra
T
in
Kennedy's
name,
so
that
will
cause
the
encrypting
it
was
named
to
fail,
but
they
have
they
have
a
meaning.
A
A
The
issues
that
might
come
up
next
is
Gaia,
so,
as
I
said
catch
it
this
time,
Gaia
is
a
group
that
works
on
the
Internet
protocols
in
places
where
you
may
not
have
power,
or
you
may
have
very
limited
computers,
but
you
have
you
have
some
form
of
digital
phones,
so
they
have
been
having
a
workshop
every
year
and
they
have
a
lot
of
other
things.
Let's
see,
I
gave
them
I,
don't
know
what
that
says.
A
Proposed
panel
energy,
there
sorry
I
gave
them
green
hills
of
Earth
as
their
science
fiction
title,
and
you
can
check
out
everybody's
agendas
in
the
regular
IETF
agenda.
So
so
this
is
a
good
thing
to
to
to
check
another
of
our
really
cool
groups,
and
this
is
another
was
I
like
following
Laura
says
he
came
up
with
some
very
good
groups.
He
and
the
chairs
is
human
rights
protocol
considerations.
A
Some
of
you
are
probably
in
the
Chicago
meeting
they
presented
in
the
technical
plenary,
and
they
gave
a
very
good
talk
and
then
Dave
Clark,
who
was
the
very
first
chair
of
the
IAB,
also
gave
a
talk
about
this
topic,
so
I
recommend
looking
at
the
video
of
that
Dave's
talk
was
fantastic
and
it
was
a
really
good
session.
They
are
about
to
publish
their
first
document,
which
is
a
review
of
the
research
in
this
space.
A
You
know
what
can
protocols
do
that
would
support
the
various
forms
of
equality
that
that
are
considered
so
they
base
their
work
on
the
United,
Nations
Human
Rights
declaration,
and
they
they
have
a
quite
rigorous
and
an
energetic
approach
to
things
their
meeting
and
they
meet
usually
with
us.
But
please
do
join
that.
That's
a
good
meeting
another
as
I
mentioned
is
the
internet.
Congestion,
control,
research
group
and
I
didn't
give
them
a
science
fiction
picture,
but
this
is
a
picture
from
2005
of
the
Internet
at
that
time.
A
So
there's
something
science-fictional
about
the
size
of
the
internet,
learning
the
ability
to
visualize
it.
This
is
a
great
group
too,
if
you're
in
to
math
and
control
theory,
it's
a
group
for
you-
and
we
were
looking
actually
michael-
has
decided
to
step
down
we're.
Looking
for
a
new
chair
co-chair
for
that.
A
Don't
know
how
many
people
have
heard
of
that
before,
but
but
that
group
is,
is
going
very
strong
and
will
published
some
informational
specifications
for
the
protocols,
but
there's
a
lot
of
implementation
and
deployment
like
like
the
ITF.
The
IETF
is
very
interested
in
work
that
can
be
coded
and
then
can
be
demonstrated
just
often
as
current
work.
That's
further
away
from
deployment.
A
relatively
new
group
is
the
measurement
and
analysis
for
protocols
group
which
curates
excellent
measurement
work.
A
Forward-Looking
measurement
work
may
start
to
do
some
work
on
on
ways
to
bring
together
the
different
types
of
measurement
infrastructures
that
there
are
Miria
and
Dave
are
the
the
chairs
of
that
and
I
gave
him
this
cover
because
of
Occam
scalpel,
because
good
measurement
work.
It's
easy
to
do
to
have
measurements
and
and
not
actually
have
much
information
out
of
it.
A
So
you
have
to
use
the
equivalent
of
an
Occam's
razor
to
kind
of
sort
out
what
is
meaningful
here
when
you
have
a
lot
of
measurement,
and
there
are
presentations
that
they
have
do
that
and
there's
no
implication
that
they
they
were
a
little
outfits
and
stuff
like
that,
but
okay,
so
then
I
made
holiday
the
next
part
of
this
into
into
one
slide.
We
have
three
faithful
ends
here,
the
end
star,
not
really
that
we're
coding,
which
I
mentioned
before,
which
has
which,
for
example,
would
work
on
questions
of.
A
How
can
we
get
FEC
to
work
well
for
quick?
Now
they
haven't
made
that
connection
and
it'd
be
nice
for
them
to
do
that
they
have
experts
on
FAC.
How
can
we
use
them
well
in
the
in
the
relation
to
the
ITF?
So
if
you
have
good
ideas
about
that,
I'm
interested
to
hear
from
you
Network
function,
function,
virtualization
is
a
kind
of
fad
in
industry.
A
There's
a
lot
of
startups
in
the
NFB
space
actually
precisely
defining
what
NFV
is
is
not
easy,
and
so
this
group
has
a
need
for
more
more
focus
of
what
is
nfe
and
whether
the
hard
things
that
are
useful
for
the
ITF,
it's
chaired
by
people
who
are
very
active
in
the
space.
But
it
definitely
is
an
interesting
thing
to
get
that
one
into
a
productive
focus
and
finally,
the
MMR
G
network
management
research
group.
A
This
one
has
been
around
since
I
think
the
beginning
of
the
IRT
F
with
changes
of
chairs,
and
one
reason
it
exists
is
that
there's
a
lot
of
network
management.
Research
which
is
not,
which
is
focused
on
on
theoretical
considerations,
then
brought
to
practical
use
cases.
So
there's
been
a
value
to
bringing
the
academic
community
here
for
years
and
years
and
I
think
that
they
have
definitely
been
an
engine
for
asking
questions
about
the
way
we
do
network
management
in
the
ITF.
A
That
is
a
topic
which
has
evolved
a
great
deal,
but
it's
undoubtedly
25
years
old.
So
so
it's
it's
our
senior
member
and
I
gave
them
the
three
companions
from
Doctor
Who,
because
I
had
three
ends
and
I
didn't
want
to
read
Doctor
Who
out
of
this,
then
we
get
to
the
thing
to
thing:
research
group:
we
have
a
bunch
of
protocols
in
the
ITF
that
are
serving
the
purposes
of
thing
of
things
of
the
Internet
of
Things,
which
are
working
on
the
idea
that
you
need
for
energy
protocols.
A
You
need
protocols
that
can
be
made
into
small
forms
for
condensed
or
low
capability
networks,
but
but
there's
clearly,
research
in
security
scaling.
Many
other
aspects
of
that
space,
so
Carsten
and
Ari,
who
are
very
active
in
the
ITF
side
of
things,
decided
to
form
a
research
group
on
this
as
well,
and
they
have
been
trying
to
be
very
experimental
and
how
they
do
their
meetings
as
well
with
focus
groups
and
facilitators,
and
things
like
that.
A
I
gave
them
in
honor
of
our
location,
the
Rossum's
Universal
robots
picture,
because
this
is
a
very
famous
play
that
was
written
here
in
the
Czech
Republic
about
robots
who
become
conscious
and
one
need
to
be
treated
like
humans,
and
it
was
from
a
long
time
ago
the
20s
so
so
I
don't
think
that
we're
going
to
solve
our
thing
to
think
scaling
problems,
because
the
things
will
become
sentient.
That
would
be
probably
make
it
easier
and
harder
at
the
same
time.
A
But
but
that's
what
that
research
group
is
about
and
I
think
you
I
think
they
also
are
very
eager
to
have
participants
from
the
many
spaces.
They're
working
in
this
I
mean
everybody's
eager
to
have
you
join
you're
here,
because
we
want
you
to
join
the
RTF
meetings,
most
of
some
emerging
groups,
as
I've
mentioned,
there's
a
so
I'm
going
to
describe
what
the
proposed
research
group
path
is,
but
we
have
one
that
is
already
formally
a
proposed
research
group
called
the
path
aware.
Networking
group
you've
been
a
bunch
of
chars
at
this
topic.
A
This
is
the
topic
where
the
host
or
the
end
system
can
make
a
good
decision
about,
shall
I
use.
My
shall
I
use
my
my
LT
LTE
or
shall
I
use.
The
Wi-Fi
should
I
try
to
use
an
address
which
will
get
me
routed
through
this
or
that
provider.
So
I
try
to
control
the
quality
of
service
on
my
path
in
some
way.
So
they've
been
lots
of
work
on
this
Spencer
has
been
a
veteran
of
many
of
them
actually
included.
A
One
called
trick
Chan,
but
I
feel
very
fond
of
from
my
days
as
the
area
director
for
that,
but
so
Jen
link
of
our
and
Brian
Tramel
are
picking
this
up
they're
just
starting.
This
is
a
time
to
get
in
at
the
beginning
at
the
start
of
the
path
so
to
speak,
and
then,
as
I
mentioned,
we
also
have
a
side
meeting
to
think
about
ways
that
we
could
work
on
distributed.
Internet
infrastructure.
A
This
is
another
perennial
we've
had
things
like
the
p2p
research
group
that
tried
to
have
very
decentralized
internet,
but
this
one
is
taking
up
the
increasingly
high
high
state
of
development
of
cryptographic.
Algorithms,
like
crypto
Ledger's
blockchain,
and
how
can
we
make
these
things
as
I
mentioned
scale?
Well,
but
also,
how
can
we
build
them
into
our
protocols
in
sensible
ways
that
will
stand
the
test
of
time?
I'm,
also
very
interested
in
forming
a
group
similar
to
the
to
the
CFR
G,
that's
on
privacy
enhancing
technologies,
and
that
is
something
that
you
know.
A
What's
the
space,
probably
next
time,
we'll
have
a
meeting
about
that.
So
what's
the
vision
of
the
IETF
in
the
Ellison
Menken
years,
I
continue
to
want
to
have
academic
and
industry
research.
Folks,
here
and
I
have
been
at
the
ITF
since
the
time
when,
when
it
was
more
researchers
than
industry,
so
I
know
that
that's
a
good
state
to
have
a
lot
of
interaction
between
those
two
groups.
A
I
also
want
to
make
sure
that
we
continue
to
be
a
place
where
the
global
aspects
of
internet
are
considered,
and
you
know
Gaia
Gaia
is-
is
very
interested
in
meeting
in
places
they're,
not
there
and
I
guess.
What's
the
word
for
this,
the
great
so
meeting
in
places
they're
not
Europe
in
the
US,
and
you
know
the
Japan
and
trying
to
make
sure
we're
engaging
enough
people
there
in
addition,
continue
to
incubate
and
continue
to
find
new
ways
that
we
can
work
well
and
I
have
a
couple
specific
items.
A
A
Now,
how
does
a
group
get
formed?
That's
the
part
I
mentioned
to
you
that
Lars
made
it
easier
to
become
a
group,
so
it's
quite
hard
to
become
a
working
group.
You
have
to
go
through
a
lot
of
hurdles.
Many
groups
don't
make
it
when
they
do
it
off.
There's
lots
of
guidance
on
this.
The
idea
for
the
research
groups
is
that
we
don't
know
what
the
outcome
is
going
to
be.
We
can't
say
necessarily
so
we
don't
want
to.
A
We
don't
want
to
do
as
much
constraining
at
the
beginning
as
we
might
do
for
working
on.
So
we
have
the
idea
that
you
can
become
a
proposed
research
group
and
going
to
try
out
for
a
year
and
then
this
side
is
this
going
to
continue
or
not.
Now
that
doesn't
mean
everybody
can
just
form
a
proposed
research
group.
So
one
of
the
right
Iria.
What
is
there
needs
to
be
an
active
curly
of
people
who
are
advocating
to
do
this
work?
We
need
to
feel
that
people
will
be
somewhere
doing
the
work
together.
A
Usually
a
mailing
list
is
a
start,
but
do
you
have
a
plan
for
how
you
would
connect
people?
Are
you
going
to
meet
at
certain
conferences?
How
can
you
make
sure
you
have
a
good
crew
of
good
people
involved?
The
qualities
of
the
leadership
are
really
important
and
that
is
really
kind
of
a
personnel.
So
these
I
start
leadership.
Jobs
are
kind
of
personnel
jobs
in
a
lot
of
ways
and
I
role.
A
So
there
we
go
all
right,
so
you
could
start
doing
this
survey
now,
while
I
call
for
questions
and
stuff,
because
I've
been
told
that
they
note
that
our
educate
Miriam
is
the
representative.
The
AG
team
here
really
wants
to
make
sure
you
do
the
survey
and
I
hope
you
enjoyed
this
and
I
have
time
for
lots
of
time
for
questions
and
if
the
answers
aren't
like
amusing
enough
to
you,
I'm
showing
you
my
kittens
with
a
computer
with
an
ITF
sticker.

What's
the
connection
between
the
IRT
F
and
the
IAB,
it's
complicated
how
okay!
So
that's
it!
That's
all
I
have!
But
if
you
have
questions
come
up
and
talk
to
me,
I
hope
to
see
you
in
fact
I'm
counting
on
seeing
you
I've
memorized
your
faces
and
I'm,
counting
on
seeing
you
in
one
or
another
of
the
IRT
F
groups,
so
be
there
where
the
cool
kids
right.
Everyone
says
that,
but
we
are
okay.
