1 DOCUMENT #:GSC15- GTSC -13 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 Global Standards Collaboration (GSC) GSC-15

2 Highlight of Current Activities Standardization about Home Networking (HN) in Japan Now on 2nd stage of standardization QoS, Data Model: Investigated several existing recommendations Control and Operation: Standardized Home-network Topology Identifying Protocol (JJ ) Research: Applications realized in NGN New SWG started to standardize the network middleware for the communication between access gateway and home terminals. 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 New Generation Network Promotion Forum in Japan: IP network WG: Research technical demands HATS[1] in Japan Tested NAT Traversal function between network and home equipment. 2 Note[1]:

3 Strategic Direction Architectures and PHY 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 There are many types of end terminal and network equipment. For the management of home device, certain device lists will be required. 3

4 Challenges Confirm interoperability of Control and Operation: Standardized Home-network Topology Identifying Protocol (JJ ) Standardization of device information list in HN Standardization of JT-G9960 (Based on G.hn: G.9960) in Japan suitable for Japanese network environments. Cooperation items with other standardization bodies Data models Appliance device control (TV etc.) 4

5 Next Steps/Actions TTC will conduct the network middleware for the communication between access gateway and home terminals. Examination and standardization of sharing of Interface to achieve service on service platform. Service platform for several Applications. (DLNA, ECHONET…) 5

7 Activity of Japan 7 Confirm the interoperability between several home equipments and Service Providers including network. Interconnection Develop or confirm several application and technology about Home network. Management and maintenance technology Easy connection to home network Energy consumption control R&D UP/ Down stream to related Standardization committee Specify the detail items about home network Standaization Next Generation IP Network Promotion Forum TTC Next Generation Home Network WG HATS New Generation Network Promotion Forum

8 Tested NAT Traversal function between network and home equipment NAT Traversal (UPnP-IGD): IGD (Internet Gateway Device) of UPnP is one of the methods of NAT Traversal. UPnP: Universal Plug and Play IGD: Internet Gateway Device NAT: Network Address Translation NAT Traversal (UPnP-IGD) Services Each company IGD(s) (SOHO router etc.) Internet Home Terminals Verification tool (PC: Software) Video Contents VoIP UPnP Universal Plug and Play Verification tool (PC: Software)

9 Scope of Control and Operation: Standardized Home-network Topology Identifying Protocol (JJ ) This figure shows the control and operation in HN.

10 Detail information of Control and Operation: Standardized Home-network Topology Identifying Protocol (JJ ) Mounted FunctionExpanded function Parts End Terminal Controlled device function of UPnP Device Architecture Newly defined the element by UPnP DDD to inform the device information, and shows the format to describe to existing elements. Network Equip- ment LLDP Agent (Transmit only) function of IEEE 802.1AB-2009 Division, the name of the maker, the model name, and the model number are stored in the vender extension. Connected composition information (MAC address table) is added to the vender extension. Destination MAC address is set to the broadcast address. Division: (Newly defined, see next slide) Manufacturer code: (Newly defined) Model name: Model number: In Manager, the block diagram of home Network is made by Home-network Topology Identifying Protocol (HTIP) that combined UPnP with LLDP. Network Equipment agent Manager End Terminal agent Home Network composition information is specified from information on Agent in Manager. Device information by end terminal agent Notification of equipment information and connected composition information with Network equipment Agent Network Equipment End Terminal agent End Terminal
