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-300.00)
 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
Note[1]: http://www.ciaj.or.jp/hats/e/what/about.html
 HATS[1] in Japan
• Tested NAT Traversal function between network and home equipment.
2
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
Challenges
 Confirm interoperability of Control and Operation:
Standardized Home-network Topology Identifying Protocol
(JJ-300.00)
 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
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…)

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.
