THE FUTURE INTERNET
TFI2014 Denver Colorado
You are here…
Is this the future?
SDN Falls
Decentralized

You are here
Where do we go from here?
C≤1/R
Impossible!
THERE IS NO SILVER BULLET FOR COMPLEXITY
WE NEED TO RETHINK FAILURE DOMAINS
Wish you were here…
WE NEED TO SEPARATE POLICY FROM REACHABILITY

WE NEED TO RETHINK OUR MODELS
WE’RE NOT GOING TO SOLVE DIFFERENTIATION

WHAT WILL THE INTERNET LOOK LIKE?
●“Messy, as always”
●SDNs will be overhyped and overplayed
●Back in the real world, SDNs will have an impact●Some complexity will be moved from distributed control planes into
centralized control planes
●Failure domains will be reshaped
●Policy will be separated more cleanly from reachability
●But none of these are going to be…●Done in the way we expect
●As “clean” as we might expect
PERSONAL SCALE THOUGHTS
●The command line will become less important
●Theory and principle will become more important
●Coding skills will become the norm
