CONTACT(S): Kenji Koro ([email protected])
Submission Date:July 14, 2008
TTC Next-Generation Home Network system WG
Outline:• To provide activity and future plan on Home Networking in TTC.• To provide co-ordinate activity and future plan on Home Networking in JAPAN.

-General-• Decision of the standardization about Home Networking (HN)
– Decision of architecture: The revision proposal to ITU SG9 – Interconnection: Aim at the standard establishment about a required function
and functional layout, such as a transmission system, QoS, and GW control function.
– Decision of a physical interface: Decision of a model in Home Connector– Standardization proposal to ITU-T etc. : Under proposal progress
• Investigation and analysis of related Recommendations – ITU-T, HGI, DSL-Forum, DLNA, UPnP, etc.
• Cooperation with a related organization – Next Generation IP Network Promotion Forum in Japan:
• Home Network WG: Decides Technical Demands• Interconnection WG: Examination of a test bed

Highlight of Current Activities (2)• Decision of the priority for standardization
– QoS and Remote management are the first target. – Under examination about the details of QoS, and a device list now.
• Cooperation with Next Generation IP Network Promotion Forum– Decides upon demand conditions by the Forum side, and TTC examines a
concrete plan proposal based on it. • Examination and decision of the model for apparatus management • Examination decision of a use case (Model of Profiles)

Strategic Direction• There are no synthetically Recommendation between WAN,
Access, Home-GW, and Intra-HN NW. – QoS– Operation– Connection
• Their own specification in various kinds of organizations.
• Isn't cooperation by its side necessity among several bodies?
5
Challenges• Decision of a device list
– Decision of a model in HN
• The definition of QoS – QoS in HN– End to END QoS
• Cooperation with Next Generation IP Network Promotion Forum– Demand to QoS is considered. – Interconnection Experiments.
6
Next Steps/Actions• Embodiment of use case: Internet connectivity, IP phone,
Contents distribution (included IPTV), Life system support (an Emergency dialing, Home security, Energy management, etc.) – Decision of a profiles– Define the details of each profiles
• Specification of an interface – Decision of a specification proposal
• Cooperation with related many organizations: Demand to Operation, Managements, Interconnection tests– Cooperation with the Forum intra Japan– Cooperation with the Forum inter Japan
