    • To allow bi-directional communication by using a bridge type feed and to reduce a load on equipment such as a receiver connected to a UDL network, a communication apparatus for carrying out communication on the Internet using an uni-directional communication line comprises an interface (5b) for receiving IP datagram to be transmitted to the communication line at the side for transmitting data to the communication line, and an interface (12) for realizing a virtual communication route from the receiving side to the transmitting side on the communication line, for carrying out bi-directional communication as UDLR. Moreover, the apparatus determines a destination of a packet inputted to the feed through predetermined interface, then determines which network the packet should be transferred to in accordance with the determined destination of the packet, and then transfers the packet through a predetermined interface only when transfer is necessary.
    • 为了允许通过使用桥式馈送进行双向通信并且减少诸如连接到UDL网络的接收机的设备上的负载,用于使用单向通信线路在因特网上进行通信的通信设备包括接口( b)用于接收要发送到用于向通信线路发送数据的一侧的通信线路的IP数据报,以及用于在通信线路上实现从接收侧到发送侧的虚拟通信路由的接口(12) 用于执行双向通信作为UDLR。 此外,设备通过预定接口确定输入到馈送的分组的目的地,然后根据分组的确定的目的地确定分组应该传送哪个网络,然后仅在转移时通过预定接口传送分组 是必要的。
