4.1.1.2 2-Box model
The 2-Box Model describes a configuration in which the server is discoverable in the home network. Since the client
is not discoverable, it must have a UPnP Control Point in order to be functional in the network to be able to discover
an AG device description (as defined in Section 10 of [PROT]), or a Remote UI server description as described in
Section 5.1 of [CEA-2014-A].

 

4.1.1.2 2-Box 模型

2-Box模型描述了一种家庭内网中的服务器是可被发现配置。由于客户端是不易被发现的（译注：由于内网环境，不断变换的地址，NAT转换，穿透等问题），其必须包含一个UPnP控制点，用以使网络能够发现AG设备的相关描述（在【PROT】文档第10部分定义）或发现一个远程UI服务器的描述（就像【CEA-2014-A】第5.1节中描述的那样）。

 



 

=================================================================================

4.1.1.3 3-Box model
When both the Remote UI Server and the Remote UI Client are discoverable, the configuration can be described by
the 3-Box UI Model. This configuration has no restriction on the location of the UPnP Control Point for the discovery
and connection management, as illustrated in the diagram below. 

 

4.1.1.3 3-Box模型

如果远程UI服务器和远程UI客户端都是可以被发现的（可访问的），这种配置在3-Box模型中描述。这个配置没有对UPnP控制点的发现和连接管理位置的限制，如下面的图所示。
