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.

Abstract: A communication system comprises: a node that requests a processing rule for processing a packet; a control apparatus that notifies a processing rule to the node in response to the request; and a plurality of path calculation apparatuses that calculate a forwarding path of the packet received by the node. The plurality of path calculation apparatuses calculate the forwarding path based on at least one policy for calculating the forwarding path, and notifies the calculated forwarding path to the control apparatus. The control apparatus generates based on one of a plurality of the notified forwarding paths the processing rule for forwarding the packet received by the node.
