Goals of the CISE Reorganization
• Remove program duplication
• Establish an intellectually coherent set of divisions and
clusters
• Decrease proposal overhead for investigators
• Sharpen focus of CISE programs
• Increase grant size and duration
• Integrate education and research
• Broaden participation in CISE activities
page 19
Wei Zhao

What’s new in the reorganization?
• New divisions and programs
• Clusters: Larger programs with teams of program
directors working together
• Themes: cross-divisional activities and priority areas
– Cyber trust
– Broadening participation
– Science of design
– Information integration

Limits of Today’s Internet
Today’s Internet
– Not designed for today’s use
– Poses various limitations
page 23
Wei Zhao
3/25/2005
Limits of Today’s Internet
• Commercial Competitiveness
– Designed without commercial consideration
– But now, competition and economic incentives
must be in place as a key infrastructure
• Services
– Designed to provide a best-effort packet
delivery service,
– But now, more and more applications demands
high bandwidth and/or guaranteed real-time
services
page 24
Wei Zhao
3/25/2005
Limits of Today’s Internet
• Security
– Designed for friendly traffic
– But now, some traffic are adversarial
• Access Devices
– Designed for desk top to desk top
connection
– But now, edge devices are very
diversified. with an increasing number of
sensors and mobile devices
page 25

Technology Push
• Sensor and RFID Networks
• Software Radios & Programmable Wireless Nets
• Mobile Ad hoc Networks
• System on Chip
• Photonic Integrated Circuits
• Real-time schedulability guarantees

Reinventing the Internet
Will entail:
 New architecture
 New protocols
 New instruments and experimental
facilities
 New theory and applications

Community Cooperation Required
– Leadership and coordination of government
agencies
– Theoretical investigation into new protocols and
models
– Engineering development for new instruments and
experimental facilities
– Domain experts for new applications
– Teaching faculty for new and revised education
programs

Summary
Information technology is still in its early
stages of development.
Thus,
1. a coherent national strategy and
2. the ability to keep reinventing itself
are absolutely necessary
