CISE OrganizationCISE Organization

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

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

Wei Zhao 3/25/2005


• 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

Wei Zhao 3/25/2005


• 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

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

A Workshop on GENI Vision and Planning

Aug 22, 2005

Community Cooperation Required

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

Wei Zhao 3/25/2005

SummaryInformation 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

Wei Zhao 3/25/2005

Now that GENI is out of the

bottle – –
