scope:

Considering that, in the future, the home network will be interconnected with the next generation network (NGN), this Recommendation describes the generic home network architecture from the viewpoint of the NGN architecture. [ITU-T Y.2012] defines the transport stratum as well as the service stratum. Considering these, the generic home network architecture can be separately discussed both in the transport layer categorized in the transport stratum and the application layer categorized in the service stratum. This Recommendation references the former model. Note that the latter model is specified in the companion recommendation, [ITU-T H.622]. Its detail will be described in clause 6.

This Recommendation discusses the interfaces between access networks and home networks, including interfaces within home networks as well as legacy interfaces. However, interfaces for off-air broadcast services are not considered in this Recommendation. Interfaces in the home network as well as the interface to the access network are shown as reference points, while proposed demarcation points for the customer and the operator are also shown in this Recommendation. Moreover, this Recommendation identifies key transport technologies for an operator to consider when providing services relevant to home networking.

In summary, this Recommendation addresses layer 3 of the home network architecture, while [ITU-T G.9960] addresses the home network architecture in layers 2 and 1. Moreover, this Recommendation describes the high level requirements for layer 2 and 3 transport technologies from the viewpoint of the interaction between access network and home network, while one of the detailed requirements and specifications for the layer 2 transport technologies within the home network can be found in [ITU-T G.9960]. The detailed description regarding the relationship between this Recommendation and [ITU-T G.9970] can be found in Annex A.
