Global Standards Collaboration (GSC) 14 DOCUMENT #: GSC14-GTSC-027 FOR: Presentation SOURCE: TTC AGENDA ITEM: 4.3: Home Networking CONTACT(S): Kenji KORO Home Networking activities in TTC KENJI KORO TTC Next-Generation Home Network system WG Geneva, 13-16 July 2009 Fostering worldwide interoperability Highlight of Current Activities Standardization about Home Networking (HN) in Japan Now on initial stage of standardization QoS: Investigated several existing recommendations Data Model: Analyzed dependencies on applications Operation: Analyzed the functional requirement Research: Applications realized in NGN Research the physical interface including 802.XX, access point base station(Femto) and ZigBee. Plan to submit proposal to ITU-T SG15, SG16,etc. Cooperation with the related SDOs and Fora ITU-T, HGI, BB-Forum, DLNA, UPnP, etc. Cooperation in Japan Next Generation IP Network Promotion Forum in Japan: Home Network WG: Research technical demands HATS[1] in Japan Established new WG for interconnection verification Note[1]: Non profit organizations for inter-operability http://www.ciaj.or.jp/hats/e/what/about.html Geneva, 13-16 July 2009 Fostering worldwide interoperability 2 Strategic Direction Architectures have been proposed by several bodies such as ITU and Fora. But there are no consistent suite of Recommendations from WAN to HN dealing with the following items. Maintenance (In case of the problems or failure has occurred) Device setting Device composition confirmation In Layer 2/3, there are many candidate protocols. But for the management of home device, some modification will be required. Isn't cooperation necessary on this respect among PSOs? Geneva, 13-16 July 2009 Fostering worldwide interoperability 3 Challenges Conduct systematic technical test composed of WAN, Access, Home-GW, and Intra-HN in close cooperation with Fora in Japan. Operation from WAN to HN Energy saving in the HN Home Security Cable application Confirm total interoperability. Examination of device list in HN Examination of a model in HN Cooperation items with other standardization bodies Data models Appliance device control (TV etc.) Geneva, 13-16 July 2009 Fostering worldwide interoperability 4 Next Steps/Actions Define the control and operation specifications for related use cases. NGN application Contents transmission/reception Click to Call Multi-media communication Etc. Network consumer electronic devices management Maintenance Device setting Device composition confirmation Confirm total interoperability. WAN to HN operational interoperability test in HATS Geneva, 13-16 July 2009 Fostering worldwide interoperability 5 Supplementary Slides Geneva, 13-16 July 2009 Fostering worldwide interoperability 6 The control and operation in HN This figure shows the control and operation in HN AGW: Access Gate WAY PC note wifi port Visible composition image AGW DVD recorder port4 port6 TV port1 port2 Network Devices port3 port4 NW Support Center SONY PS3 Nintendo Wii Range of examination of standardization User Operations Grasp of connected equipment/composition First Target Geneva, 13-16 July 2009 Far end services Connected confirmation Quality measurement Maintenance (In case of the problems or failure has occurred) Device setting Fostering worldwide interoperability 7 Requirement for HN/ Technology Service requirements END-Devices (including AGW) Network device (including AGW) Specific of end terminal Notification of equipment information Grasp of connected Collection/accumulation of equipment information and LAN equipment equipment/ composition Specific of HN composition Notification of composition information Connected confirmation For trouble/ prevention Device setting Watch and abnormal detection Setting, operation and confirmation Setting and initialization, firmware update and restart Priority Responds to connected confirmation. Confirmation of connectivity such as rink information. Notification when abnormality occurs Acknowledge to the polling demand. Responds to operation (log) confirmation. The event (log) to AGW. The command is executed, and the result is returned. Send quality value confirmation. Acknowledge to the quality value confirmation. Packet count at each port/flow Field strength/modulation method (For the wireless and PLC) Bandwidth etc. Quality measurement Geneva, 13-16 July 2009 Fostering worldwide interoperability 8 L2/L3 Protocols Functional Requirement Notification of equipment information Notification of MAC address table Geneva, 13-16 July 2009 Candidate Protocols L2（To LAN devices） LLTD (IEEE) LLDP (MS) L3（End Devices） UPnP or + Enhancing NetBIOS or + Enhancing DHCP Vendor code Enhancing ICMP echo body Enhancing TR-069 or + Enhancing SNMP Fostering worldwide interoperability 9 PHY/MAC layer Technologies Cable G.hn Bit Rate Multipoint 1Gbps (Coax, Phone ） 300Mbps (Power Line) YES Coax.
