GENI Initiative: Goals• Invent innovative internet architectures and

distributed system capabilities -- go beyond Internet

• Enable seamless conception-to-deployment process– Facility for experimentation at scale with apps and users

• Work with broader community– Academic and industry communities

– Other US and international agencies

Challenge: Research Community to Create Future Internet -- Internet for the 21st Century

What is Different This Time?• Clean-slate approach

– To overcome Internet ossification– Research not constrained by the features of the current

Internet

• 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

April 22, 2023 6

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

Different Scale and EmphasisEnable exploration of new network architectures, mechanisms, and distributed system capabilities

A shared facility that allows • Concurrent exploration of a broad range of

experimental networks and distributed services

• Interconnection among experimental networks & the commodity Internet

• Users and applications off GENI able to “opt-in” (discover and participate in GENI services)

– ‘Native’ GENI users and applications also in view

• Observation, measurement, and recording of outcomes

– Strong scientific base, as well as research field in its own right

Community Process • Competitive but cooperative

– Within PI community– Within an agency such as NSF– Across federal agencies: NSF, DOD, DOE, …– Across international agencies

• Diversity - comprehensive but focused– Technologies vs. architecture– Applications vs. architecture– Center of gravity: which layer(s) of protocol(s)

• GENI one of many facilities for the net community– GENI documents its scope and is not “all things to all

people”

April 22, 2023 19

Challenges • GENI facility construction a complex project

– Needs innovative project management

• Community consensus and convergence

– Without curbing creativity and radical thinking

– While providing for broad range of experiment communities

• Global collaboration

– With agencies and research communities

– Effective federation: technical as well as policy solutions

GENI Challenge to Community

• Design the Future Internet that makes us proud.

• Create a world in which we want to live.
