Information Technologies
Impact many sectors of society
Increase productivity
Stimulate logical-thinking
page 6 Wei Zhao 3/25/2005
Current Environment
Enrollment down Tough job market More and more global competition Dissatisfaction from business users Budget constraints and cuts Less and less major breakthroughs
What is wrong?

Information Technologies
Product oriented
Invented for precursor systems
Lack of a sound design methodology
Ill-suited for increased user demands

CISE OrganizationCISE Organization
page 19 Wei Zhao 3/25/2005
• 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
Goals of the CISE Reorganization
page 20 Wei Zhao 3/25/2005
• 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
What’s new in the reorganization?

Limits of Today’s Internet
Today’s Internet
– Not designed for today’s use
– Poses various limitations
page 24 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 25 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 26 Wei Zhao 3/25/2005
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

A Workshop on GENI Vision and Planning
Aug 22, 2005
Community Cooperation Required
page 35 Wei Zhao 3/25/2005
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
page 36 Wei Zhao 3/25/2005
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

Now that GENI is out of the
bottle – –
Any Questions?
