Abstract
A plurality of forwarding nodes includes: a topology holding unit that holds as first topology information connection relationship between an own node and at least part of the group of nodes; a topology notification unit that notifies a node(s) adjacent to the own node among the group of nodes of the first topology information; and an in-band communication unit that notifies a control apparatus of the first topology information. The control apparatus includes: a topology configuration unit that generates second topology information by combining a plurality of pieces of the first topology information notified by the plurality of forwarding nodes; and an in-band control unit that derives a path from the control apparatus to the plurality of forwarding nodes based on the second topology information and establishes a control channel for controlling the plurality of forwarding nodes along the derived path.
