摘要

The distribution system of film, subscriber line termination device, distribution method of film, film distribution program and recording medium. The present invention provides a network independent that allows quick and economic restoration of communications.For this purpose, the present invention additionally provides autonomous network devices to a network we additive B, and adds an interface card to each node of a network device to connect the existing network to network B.Devices for nodes of the network to additive B are connected together in a mesh type, and configure a autonomous system separated regardless of the existing network a. the network additive and is dedicated to a route backup to the existing network a.The network and suppresses the bandwidth of the link or the transmission capacity of devices for us to be even smaller than that of the existing network such that the network and can be economically established in a small size.The network additive and is established to temporarily carry part of the traffic in a case where the existing network the decomposes or is subject to restoration of decomposition. This network B does not require large transmission capacity.
