-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

Highlight of Current Activities (1)

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)

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?

Page 5: Home Networking activities in TTC

Challenges

• Examination of a device list – 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.

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
