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 4, 2008

2. Highlight of Current Activities (1)
-General-
Propose the standardization about Home Networking (HN) in Japan
Examination 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.
Examination of a physical interface: Examination 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: Examination of Technical Demands
Interconnection WG: Examination of Test bed

3. Highlight of Current Activities (2)
Examination 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
Examination upon demand conditions by the Forum side, and TTC examines a concrete plan proposal based on it.
Examination of the model for apparatus management
Examination of a use case (Model of Profiles)

・Setup
・Apparatus specification
・The surveillance/notice of NW connection / quality
・Apparatus state detection and a notice

4. Strategic Direction
There are no synthetically Recommendation between WAN, Access, Home-GW, and Intra-HN NW.
QoS
Operation
Connectivity
Interconnection
Their own specification in various kinds of organizations.
Isn't cooperation by its side necessity among several bodies?

5. Challenges Examination of a device list The definition of QoS
Examination 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.)
Examination of a profiles
Define the details of each profiles
Specification of an interface
Examination 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
