1. OpenStack
Networking
Service
11/10/2010

2. Goals
• Networking
as
a
first
class
service
that
can
;e
together
network
“endpoints”
from
different
services.
• Provide
flexibility
in
networking
implementa;ons
with
plug-­‐ins
that
implement
a
generic
network
interface:
– Network
segmenta;on/provisioning
– IP
address
management
– Business
logic
to
determine
what
customers
are
allowed
to
configure
with
networking.

3. Scope
• Network
service
only
manages
connec;vity
+
addressing,
which
are
shared
across
services.
• Compute,
Firewalls,
Load
Balancers,
VPN,
etc…
should
be
separate
services,
and
would
consume
the
networking
service.

4. Why?
• Why
1st-­‐class
service?
– Cloud
is
about
orchestra;ng
all
kinds
of
services,
not
all
will
be
provided
by
compute
VMs.
Network
must
be
able
to
;e
together
all
such
services.
– Single
integra;on
point
for
networking
logic,
instead
of
having
to
do
it
in
each
service.
• Why
plug-­‐in
design?
– Want
to
incorporate
“best-­‐of-­‐breed”
networking
solu;ons
that
solve
cloud
networking
challenges.
Best
solu;on
may
depend
on
provider.
– How
and
to
what
degree
customers
can
manipulate
networking
will
depend
on
provider.
Need
customer-­‐aware
“business
logic”
to
manage
things
network
crea;on,
network
associa;ons,
IP
addresses.

5. Use
Case
Examples
• Private
tenant
network
with
VPN
network
connec;on.
• Firewall
service
with
interface
on
public
interface
and
interface
on
a
private
tenant
network.
• Mul;-­‐;er
web
applica;on,
web
VMs
have
two
interfaces,
one
on
public,
one
on
private
backend
network
with
DB
servers.

7. What’s
Next?
• This
is
a
long-­‐term
project.
Want
to
get
started
during
Bexar.
• Plan
to
create
group
of
interested
par;es
for
detailed
designed
discussions,
coordina;ng
coding.
• First
goal
will
be
to
implement
exis;ng
OpenStack
nova
networking
func;onality
as
“default
plugins”.
