Issues for Information Explosion in
the Communication Network
•ABUNDANT resources:
•Bandwidth (Bandwidth blowout by photonics and
next generation mobile)
•CPU Power (Silicon progress, Moore’s law)
•SCARCE resource:
•User’s Time (Difficulty of finding right information)
(George Gilder)
Key for the user-friendly communication

“User’s Time” Conscious Approaches
1. Service management
2. Agent technologies
3. Tele-presence / Tele-cooperation
4. User-friendly Interface

End-to-end Quality of Service Management
• Provide user pertinent information with required quality and ease of access
• Policy-based control and guarantee of quality offered by heterogeneous
application, system and network

What Agent Technology can Provide
• Easy access to services by hiding differences of
– Access network systems
– Server/database systems
• Adaptive selection of services
– Geometry dependent information filtering
– Selection of available communication method
• User customized services

Virtually Integrated Database
Direct access to databases
• Users must know where databases
are, and how to access them.
• Users must access to each database
by themselves.
User
Database
Brokerage by a facilitator
• Users must know only a facilitator.
• The facilitator accesses databases
on the user’s behalf in parallel.
Distributed facilitator

FIND-Future - Application of Agent
• Searching various databases in Fujitsu intranet
• Retrieving appropriate information efficiently using an
experienced search agent
• Now in service and used by systems engineers at Fujitsu

Status of Find-Future
• Users make queries with keywords
• More than 40 servers distributed across Fujitsu
have joined.
– 40,000 system engineers are using.
– Database agent software is distributed
throughout field SE divisions for their
servers to join.
• 80% of the queries are answered within 2 seconds.

Approach of CHOCOA
Product initiated by necessity
Advantage of large room
– Always possible to see each other (Awareness)
– Always possible to talk to each other
– Multi-person discussion is possible
Virtual large room (for researchers and engineers)
– Real-time and quasi real-time communication system
– Media : Multi-user and multi-party text chat system
＋
Voice for compensation of text’s drawbacks
Technical background
Telephone system: Circuit-switched --- Always-ON is expensive
Internet system: Packet-switched --- Always-ON is possible
