A simple definition for Federation
occurs when two or more
organizations agree to each allocate
some of their resources to implement a
– Share connectivity and multiple levels of protocol
– Share routing information
– Distribute configuration
Carter phone Decision
– Create interface for communication devices
The reasons f federation revolve
for f d ti l
around mutual benefit, but in practice are
quite different f different t
it diff t for diff t types of
Corollary:a particular federation or
federation technology can be attractive or
unattractive to different organizations
– Maximize overall economy
– Maximize overall user satisfaction
– Minimize risk
– Regulate monopolies; encourage competitiveness;
smaller and more numerous markets
– Encourage best of breed solution finding
– Persistent competitive advantage
– Leverage strategic advantages to new
– Reduce risk
– Own monopolies or near monopolies
– Commodity i
C di inputs; proprietary outputs
– Best technology
– Best Price
– Ease of use / Least investment in learning
– Purchasing h i
P h i choices
– Influence on Government
– Freedom to explore alternatives
– Joint efforts to aggregate scarce resources
– Embrace di

Makes eminent sense for researchers
i t f h
– Scale of all academic resources less than
that of production systems by orders of
• E.g. PlanetLab, OneLab
• Use individual’s phones as distributed sensor net,
or intermittently connected testbed
Little advantage t d f Cl d providers
d t today for Cloud id
– Makes their output a commodity
– Scale isn’t an issue
– Coverage isn’t an issue (y )
Perhaps federate lower levels?
(f d t commodities, not discriminators)
diti t di i i t )
Can we use f d ti t reduce risk?
federation to d i k?
– Avoid cloud lock in
– Handle demand surge
Connect different cloud apps
– Inevitable once separate cloud-based apps
get important enough?
t as big enterprises
bi t i
– Lots of resources to share & save
– Lots of data to make available, internally and
– Load moves around (e.g. IRS in April?)
Governments as regulators
Lots of forces work against federation

We want to make consolidation happen

but there’s i base of f
How t shape academic efforts so that
to h d i ff t th t
they will be relevant to the other worlds?
– E.g. Agenda and participation in NSF
Isit the same as networks before the
(ARPAnet extinction; start of the Internet age)
Si il iti
– Lots of production proprietary inertia
– Ease of experimentation with multiple open
standard OSes, etc.
– Cheap hardware
– End of the hourglass model
End of the hourglass?
IP is th center of the Network just as the earth
i the t f th N t kj t th th
is the center of the universe.
’still the most important f
frame of reference,
but not the only one.
– Ethernet may be the way to port servers in
– Custom content based networks need not be IP
The Gravitational model
We have large adoption (
h l d ti (mass) of certain
) f t i
standard protocols, uses and interfaces.
IP users, movies, web, games, …
There’s a huge attraction to finding a better
path b t
th between any t two of these (so long as you
f th ( l
don’t fall into another gravitational well)
leads to multiple paths between the
biggest masses, or a polymorphic net.
