Whence we came from and where do we go

Ed Knightly

What is success?

Different research is successful in different ways and there are many dimensions or success and impact

A research effort should be considered successful if it satisfies any of these criteria

Ed Knightly

What is success?

Adoption in products/large user community– Classical criteria

Solution to real-world engineering problem– Ex. Route flapping BGP

Development of design principles– Ex. WFQ

Creation and enabling of new modes of communication– Ex. Multicast, location aware services

New abstractions, models, and tools with long term value– Ex. Network calculus

Create fundamental understanding of networking behavior– Ex. Statistical multiplexing, scalability of ad hoc networks

Education

Ed Knightly

Case Studies from the Past

Multiple access Quality of Service Optical networks Congestion Control Traffic Modeling Multicast Active networks Cellular WFQ

Ed Knightly

Present State

Many communication modes have already been explored

No technological hurdle to integrated services

Ed Knightly

Future directions

Design protocols, architectures, theory, testbeds for future networks that enable new applications and new modes of communications.

Examples– Bandwidth on demand– High availability/resilience – Pervasive high-speed wireless with mobility– Pervasive high-speed residential access– Secure/DoS resistance– Location aware services– Energy efficiency

Observation (Innovator’s Dilema)

Today’s network of the past: designed by bell-heads

Tomorrow’s network of the past: designed by hour-glass heads

Past: needed new community to think radically

Future: do it ourselves

Ed Knightly

Methodologies

Platforms for moving forward– Overlays– Re-engineer today’s protocols– Fresh start / clean slate

Enhanced ability to measure success – Benchmarks– Reproducibility (public data, simulation code,...)
