FIND Challenge to the Research Community:

Create the Future Internet you want to have in 10-15 years

3

The Future Internet

Must

• Be worthy of our society’s trust– Even for managing and operating critical infrastructures

• Provide a bridge between physical and virtual worlds– Via instrumented and managed sensorized physical environment

• Support pervasive computing – From wireless devices to supercomputers

– From wireless channels to all optical light-paths

• Enable further innovations in S&E research– Seamless access to networked instruments, supercomputers,

storage, etc.

• Create a social world in which we would want to live

4

What is Different This Time?

• Clean-slate approach

– To overcome Internet ossification

– Research not constrained by the features of the current Internet

– But does not mandate rejecting what currently works

• A comprehensive coordinated effort

– Ability to try different approaches (We do not have a preconceived idea of what they are)

• Ability to experiment at scale

– With real users and applications

5

Success Scenarios

• Internet evolution influenced by clean-slate approach

• Alternate Internet architecture emerges

– Alternate architecture(s) coexist with the current Internet

– Virtualization becomes the norm with plurality of architectures

– Single architecture emerges and dominates

• New services and applications enabled

• Many other payoffs

– Some unexpected

6

FIND - Different Process• “Goal” oriented Future Internet

– Not typical for NSF research programs– Area has a longer timescale with sustained funding

• Three phases -- iterative and overlapping– Exploration of architectural components and 1st cut overarching

architectures– Convergence into multiple full-scale architectures– Experimentation of architectures at scale

• “Competitive cooperation” model– Competition to bring out the best– Cooperation to build on each others work to deliver Future

Internet• Competition – Proposal reviews• Cooperation – Among awardees

– Regular meetings -- three times a year– Commitment to openness and transparency

7

Stages of Research2006-2007

• Research on architectural elements

– Naming, identities, forwarding, interdomain

protocols, etc.

• 1st Cut overarching architectures

• Cross-cutting requirements of built-in

security, robustness, and manageability etc.

• Transformational architectural ideas (like

packet switching was for the Internet)

8

Stages of Research2007 and Later

Coordinated effort to assemble overarching

coherent architectures

• Multiple PI meetings to formulate architectures

– FIND awardees

– But also other “architectural” researchers e.g. funded

by NeTS, CyberTrust, DARPA, industry, internationally

funded researchers, etc.

• Small number of architectures developed

9

Stages of Research2008 and Later

Architectures as they emerge will be made

operational and tested

– Simulation

– Emulation

– Run on a large-scale GENI facility

• Experiment with new architectures at scale

10

Where are we now?

11

FIND 2006

26 of 98 projects awarded – some 1 year seed investments

NeTS = $40M

FIND = ~$15M (38% of NeTS)

12

FIND 2007

• NSF 07-507; January 22, 2007 deadline• First FIND PI meetings

– Begin to create a FIND community and identify areas of commonality and differences, open research areas

• FIND project descriptions at: http://nsf-find.cs.umn.edu

• Process for including FIND-like researchers from industry, international and academics funded elsewhere

13

FIND Portfolio• New architecture principles

– Composable architectural building blocks– Recursive network architecture

• Delay tolerant network architectures– Disaster networks– Cache and forward network (for large files)

• Network technology and architectures– Wireless Networks– Optical Networks

• Higher bar—be more architectural• Services architectures

14

FIND Portfolio• Virtualization

– New “layer 2+” hour glass– New e2e services from virtual nodes & links

(multiple hour glasses)

• Sensor networks• Security

– Default off and least knowledge– Packet attribution with privacy preservation

• Routing– User controlled routes

15

FIND Portfolio

• Object identity and naming– Handles for naming, security &

communication paradigms– Usable namespaces for small devices

• Economics and network architectures– Market enabling architectures

• Management– Manageability in routing systems– Model-based diagnosis of the knowledge

plane

16

Lessons from FIND 2006• Is it networking? Does it belong in NeTS?• Is it architectural? Does it belong in FIND? How well

does it address architectural issues?• Is it “clean slate”? Is it appropriate for a “Future

Network”?• Is there evidence of a deep understanding of the

(hard) issues?• Will it scale?• Can it be secure?• What about overhead or complexity?• Is it economically viable? • Have ideas already been tried?—need good

understanding of the literature and history of the field when rethinking old ideas

17

Lessons from FIND 2006

• Is there a unifying theme of ideas—or just a “grab bag” of ideas?

• Is there an evaluation plan for the new ideas?• Is there a well developed plan for the integration

of education and research?• How will the PIs involve students in the FIND

research?• What is the broader impact if successful? Does

the idea matter? Want to hear “if successful, these ideas would have a profound positive impact on the Future Network.”

18

Lessons from FIND 2006• Too many ideas merely extensions of

current Internet or P2P networks• Too many were technology, not

architecture proposals• Too many use assumptions appropriate

for the current Internet• Not just “fix the Internet” mentality• It does NOT have to fit within today’s

vision of GENI’s capability—GENI will evolve

19

Guidance to FIND Proposers• Think of creative yet well-considered ideas • Clearly show how the proposed work

addresses one or more Future Internet requirements (e.g. built-in security, economic viability, manageability)

• May submit architectural components, architectural theory, 1st cut overarching Architectures (not just critique of Internet)

• Discuss how your work would fit into a larger overall network architecture

20

FIND Review Criteria

• Intellectual Merit

• Broader Impact

• How well the work addresses architectural requirements

• How well the proposed work relates to and enhances overall architectural framework

• Importance of work to framing a new architecture
