A content distribution system in which content is distributed from a broadcasting station via a plurality of nodes connected in a hierarchical tree structure, including: a base tree obtained by connecting the plurality of nodes in a hierarchical tree structure using the broadcasting station as an apex; an extension tree obtained by connecting the plurality of other nodes in a hierarchical tree structure using, as an apex, a first root node as any of the nodes included in the base tree; and a topology controller for controlling a topology of each of the nodes belonging to the base tree. The first root node controls the topology of each of the nodes belonging to the extension tree using the first root node as an apex.
