Home Networking activities in TTC
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.
TTC Next-Generation Home Network system WG
Submission Date:
July 14, 2008
Highlight of Current Activities (1)
-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
2
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?
4
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.
5
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
