  6. 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 FUJITSU LABORATORIES LTD.

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

  8. 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 End-to-end Quality of Service Management User’s QoS policy Application/ Network QoS - Capacity - Accuracy - Time Delay - Security - Reliability User Requirements - Ease of access - Quality - Time - Cost Telecooperation QoS Policy Mgmt User Provider QoS Control Electronic commerce QoS-enabled Application QoS-enabled services QoS-enabled Application QoS Monitor Agent Web QoS-enabled Networks/Systems FUJITSU LABORATORIES LTD.

  9. Automated systems management Enable end-to-end QoS control Integrated policy information Policy-Based Enterprise Management PSM (Policy-based Systems Management) Application management PBN (Policy-Based Networking) Cooperate Cooperate Integrated management policy Network management System management Control Status Enterprise System (application, server, client, router) QoS：Quality of Service FUJITSU LABORATORIES LTD.
