## How Would Work and Life be Different if Travel was Free and Instantaneous ?

- You would live where you want to.
- You and your colleagues would meet in interesting places.
- You would leave your things where you need them for the task at hand (assuming some security).
- You would “arrange” to meet people in certain places at certain times.
- You would need mechanisms to “locate” people and things.
- You would develop habitual places for gathering to discuss science and life.

## Technical Goal

-  Demonstrate within the SC95 conference framework a prototype implementation of a high-performance NII
- The I-WAY: ATM to ~50 sites as much   OC-3c/OC-12c as possible (enabling massive distributed computing).
- Demonstrate virtual reality navigation in large computationally intensive simulation spaces.
- Push limits of video server technology in video on demand demonstrations.
- Integrate emerging LAN and WAN (satellite) wireless networking technology.
- Gather and nurture I-WAY activities through a national call for proposals.

## The Plan

- About 50 sites ..(NSF, DOE, DOD, NASA, universities, companies, etc.).
- Connect sites via a combination of existing high-speed networks and a national testbed at OC-3c and OC-12c bandwidths.
- Ideal network testbed would exist from May 1995-May 1996.
- Provide a scalable software environment and systems management framework.
- Enable the use of many supercomputers in parallel (> 1011 Flops aggregate performance is desired).
- Generate and test a global scale VR software environment.

## Wirelss Networking

- 1 - 5 seperate IP subnets
- 20 - 200 hosts distributed across subnets
- Build a wireless infrastructure for the conference
- Enable Commonly used applications to work on a wireless network
- Test wireless networking in a live conference setting with real users
- Evaluate performance of networks
- Publicly demonstrate new wireless technology

## Why Wireless?

- Expose U.S. agency leaders in computing to new technology
- Demonstrate in real world situations the advantages of wireless networking for mobile messaging and database applications
- Demonstrate the feasibility of wireless solutions in High Visibility Conference
- Test interoperability of multiple vendor mobile wireless enabled platforms within a multi-network environment.

## Conference Committee Agencies

- ARPA
- DOE
- EPA
- NASA
- NIH
- NIST
- NOAA
- NSA
- NSF

## Collaboration is Invited

- We are interested in developing systems that will be used and are capable of large-scale deployment.
- We do not want to reinvent anything.
- We want to partner with all groups interested in the same goals (interoperability, scalability, portability, visualization and VR).
- We believe that SC95 is the ideal environment for prototyping and testing the next generation of computer tools for supporting collaborative work.

- 30 Separate Rooms
- Tent Covered Atrium
- 302’ x 300’, Ceiling 28’ - 89’, Rafters/Support Lines

## Proposed Network Characteristics

- 20 simultaneous users per location
- Continuous transparent connectivity to network while roaming
- Minimum of 4 co-located independant networks
- Cooperative aggregration of network access points to a single network
- Load balancing among co-located access points
- PCMCIA interface
- TCP/IP and SNMP support
- Access point control/configuration from Unix host

## Network Protocols

- Suppport for TCP/IP is required regardless of the underlying transport mechanism.

## Wireless Applications

- Problem Reporting and Dispatch
- Personal/Conference -related Messaging
- Synchronous (MUD) and asynchronous (Email)
- Conference Database Lookup
- Booth assignments, Network requirements
- Network Diagrams
- Show floor maps, Wiring Diagrams
- Network Management and Diagnostic Tools
- SNMP
- Preformance Measurement

## Schedule

- Quarter 1: 	Acquire and test hardware at Argonne
- 			Draft network topology
- Quarter 2:	Test hardware in the convention center
- 			Adjust network topology
- Quarter 3:	Final configuration
- 			Performance modifications of network
- Quarter 4:	 Show time: December 4 - 8, 1995

## Next Steps

- Work out the details of hardware agreements
- Determine the network layer software that will be provided
- Acquire units and test them at Argonne
- ‘Hot Test’ units in the San Diego Convention Center
- Unit Number Commitments & Schedule Buy-In
