Goals
of
this
Tutorial
• By
the
end,
everyone
should
know:
– what
OpenFlow
is
– how
it’s
used
and
how
you
can
use
it
– where
it’s
going
– how
OpenFlow
compares
to
other
plaPorms
– how
OpenFlow
fits
in
the
SoRware‐Defined

(SDN)
spectrum
• Present

What
OpenFlow
Can’t
Do
(1)
• Non‐flow‐based
(per‐packet)
networking
– ex:
wireless
protocols
(CTP),
per‐packet
processing
(sample
1%
of
packets)
– yes,
this
is
a
fundamental
limitaLon
– BUT
OpenFlow
can
provide
the
plumbing
to
connect
these
systems
• Use
all
tables
on
switch
chips
– yes,
a
major
limitaLon
(cross‐product
issue)
– BUT
an
upcoming
OF
version
will
expose
these
What
OpenFlow
Can’t
Do
(2)
• New
forwarding
primiLves
– BUT
provides
a
nice
way
to
integrate
them
• New
packet
formats/field
definiLons
– BUT
a
generalized
OpenFlow
(2.0)
is
on
the
horizon
• OpLcal
Circuits
– BUT
efforts
underway
to
apply
OpenFlow
model
to
circuits
• Low‐setup‐Lme
individual
flows
– BUT
can
push
down
flows
proacLvely
to
avoid
delays
– Only
a
fundamental
issue
when
speed‐of‐light
delays
are
large

Scope
• Different

How
OpenFlow
Helps?
• Dynamically
define

by
wildcarding
arbitrary

• Granularity
is

• Create
