Initial investigation of technology requirements for the implementation of IPv6 in M2M real-time connections
Attaching IPv6 global addresses to networked information appliances
Since April of 2004, Ubiquitous Open Platform Forum has been investigating connection conditions for "Secure, Simple and Low Cost M2M real time connection" targeted for visual communication using digital TVs and for appliance control such as monitor cameras, assuming the usage of IPv4. We decided to begin an investigation into the implementation of IPv6 as a technology requirement for equipment network connections and services that allow a global address to be attached to equipment. Please refer to the attached sheet for details.
This decision was made after observing that many Internet Service Providers (ISPs) were improving their network environment using an IPv4/IPv6 dual service, in addition to our expectation that communication complexity (including IP address translation between private and global addresses using IPv4) can be avoided.
With support from MIC (Ministry of Internal Affairs and Communications) and the participation of Forum members, a comparison between connection conditions assuming IPv4 only will be made. A summary of the investigation results is tentatively planned to be available in March of 2005.
* M2M ... Mono to Mono (item to item, or object to object)
Also, two subgroups have been setup to study the application of M2M real-time connections using information appliances. Using realistic usage, these subgroups will summarize the various requirements needed for a "Secure, Simple and Low Cost M2M real-time connection".
WG2 SWG2 "Dear to Dear" visual communication through TV
WG2 SWG3 "Home appliance remote control"
Please refer to the attachment for the details of each subgroup.

Internet connection to information appliances using a combination of IPv6 and IPv4
If an information appliance is connected to an IPv6/IPv4 dual service, then M2M applications are usable without any changes. With V6 tunneling, M2M applications are usable even with ISPs not providing IPv6.It is assumed that IPv4 will be used for existing services such as Web or Mail communication.
- IPv6 benefits
A) It is possible to allocate a global address to all information appliances. B) Avoiding connection problems caused by the NAT traversal method or its different implementations. This method enables equipment with private addressing to communicate via the Internet. - IPv6 service mode
IPv6 services are offered in the following modes.
A) IPv6/v4 dual service
This service makes both IPv6 and IPv4 available to a userfs home. Information appliances can use IPv6 without any special requirements.B) IPv6 tunneling service
In this mode, IPv4 will relay IPv6 communication. This enables IPv6 network communication via IPv4 networks. Information appliances can easily use IPv6.
If an IPv6 tunneling server and client are used, then the IPv6 tunneling service can be made available even if an ISP does not provide IPv6. - Future plans
We will encourage the participation to the Forum of ISPs including private IPv4 service providers of CATV or housing complexes, and broadband router and firewall manufacturers who are interested in IPv6 connections. We will accelerate the harmonization of technical specifications for home routers and firewalls.
The final specification will be made based on a comparison with the IPv4-based specification.
During the investigation period, connection verification will be carried out as needed.
