MOVING PICTURE DISTRIBUTION SYSTEM, SUBSCRIBER LIN TERMINATION DEVICE, MOVING PICTURE DISTRIBUTIO METHOD, MOVING PICTURE DISTRIBUTION PROGRAM, AND RECORDING MEDIUM The present invention provides an autonomou network that enables economical, swift restoration of communi tions. For this purpose, the autonomous network of the prese invention further provides node devices for an additive network , and adds an interface C card to each node device of an existing networ A to connect the network A to the network B. The node devices o the additive network B are connected to each other in a mesh t pe, and configure a separate autonomous system independently in the existing network A. The additive network B is dedicated to ackup route of the existing network A The network B suppresse the link bandwidth or transmission capacity of node devices to be ven less than that of the existing network so that the network B ma be economically established in a small size. The additive network B s established to temporarily transport some of traffics in a case w ere the existing network A breaks down or is subjected to restor ion of breakdown. This network B does not require large transmissi n capacity.
