Outline of this Speculation
• Work to date
• A global transformation is starting
• The rise of the “service store”
• Architectural, infrastructure, & economic
implications
• Next steps

No “virtual,” no “machine”

“Horseless carriage” -> Automobile

Carriage without horse Horseless carriage

No “horse,” no “carriage”
Driving the transformation -
A radical change in “router” economics

ARPANET Imp (1969)
1 core, clock ~ 1.1 MHz
64 Kbytes RAM
No disk
Today’s cost: ~ $650,000
Commodity GENI rack
Each 1U=
32 cores, 2.1 GHz
16 Gbyte, 4 Tbyte
Today’s cost: $200,000
for full rack (50 x 1U)
Economics now favor pervasive computation and storage
Disk + controller (IBM 1302)
Today’s cost: ~ $2,545,000
Disks were too expensive in 1969
1/3 the IMP’s price, but
with 1500 cores and 200
Tbytes of local storage
Instantiating services into slices
September 6, 2013 Network Virtualization Symposium 2013 8
• Soon each switching point will be
able to sustain 10,000 – 100,000 slices
• Can run arbitrary software in each slice
• Decoupling of “service” from infrastructure
Thousands of
parallel slices

� A HyperNet Builder writes a HyperNet
� The HyperNetBuilder uploads the HyperNet to the app store
� A HyperNet user downloads the HyperNet from app store
� The HyperNet user (Net creator) identifies the participants and “runs” the HyperNet
� Participants use the virtual network

The Rise of the “Service Store”
• “Drag and drop” Services
• Like an App Store . . .
• . . . that instantiates
end-to-end Services

Service Store
Tailored Service
Service instantiated in a slice
Decoupling Service from Provider
Architectural Implications
• Pervasive inter-cloud (out to the handset, sensor, …)
• Services = on-demand, 3rd party, from a store
• Services run within deeply programmable slices
September 6, 2013 Network Virtualization Symposium 2013 11
• Mutability as a key characteristic
– Services revise infrastructure as needed
– Fluid and mutable cyber security
– “Flash paper” (use-once infrastructure)
And something quite new . . .
Infrastructure Implications
• The current ‘host’ vs. ‘router’ distinction is erased
• Computation and storage everywhere
• Dramatic re-architecting of racks to support efficient
on-demand slicing of resources

Economic implications
September 6, 2013 Network Virtualization Symposium 2013 13
• “All that is solid melts into air”
-- Communist Manifesto, 1848
• “All old-established national industries have been
destroyed or are daily being destroyed. They are dislodged
by new industries, whose introduction becomes a life and
death question for all civilised nations.”
• In short, profound economic implications.
Please note: I am not, nor have I ever been, a communist.
Next steps for the US side
• Begin to remake US academic campuses
– OpenFlow & GENI Racks
– NSF CC-NIE funding
– Next-generation cyber-infrastructure
– Experimental inter-clouds
• Beef up wireless and data center aspects
– Direct wireless access to slices (LTE, WiFi, WiVi)
– Novel sliced datacenters as part of larger architecture
(moving beyond ‘multi-tenant’)
