Issues for Information Explosion in the
Communication Network

• ABUNDANT resources
• Bandwidth (Bandwidth blowout by photonics and
  next generation mobile)
• CPU Power (Silicon progress, Moores law)
• SCARCE resource
• Users Time (Difficulty of finding right
  information)
• 
  (George Gilder)
• Key for the user-friendly communication

7
Users Time Conscious Approaches
1. Service management 2. Agent
technologies 3. Tele-presence /
Tele-cooperation 4. User-friendly Interface
8
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

Policy-Based Enterprise Management

• Automated systems management
• Enable end-to-end QoS control
• Integrated policy information

Policy-Based Interworking with Enterprise
Networks

• Integrated management of IP/ATM/Photonic/Mobile
  networks
• End-to-end QoS guarantee
• User programmability for dynamic change of

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

Network Plug Play
User can access personalized service
seamlessly. Personal agent hides the difference

User Interface for Mobile Users

Virtually Integrated Database
Direct access to databases
Brokerage by a facilitator

• Users must know where databases are, and how to
  access them.
• Users must access to each database by themselves.

• Users must know only a facilitator.
• The facilitator accesses databases on the users
  behalf in parallel.

Distributed facilitator
Virtually Integrated Database

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 theirservers
  to join.
• 80 of the queries are answered within 2 seconds.

CHOCOA(CHat Oriented COmmunication Augment)

• Shared Space Informal and Simple Conversation
  in the Large Room
• Chat System for RD, Business and Pleasure
• Informal, Simple and Easy to Use Communication
  System

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 texts
  drawbacks
• Technical background
• Telephone system Circuit-switched ---
  Always-ON is expensive
• Internet system Packet-switched ---
  Always-ON is possible

Status of CHOCOA

• Freeware (Japanese and English version)
• since October
  1996
• Users (in Japan) About 100,000 (Share gt50)
• Corporate and university users 34
• Individual users 66
