Abstract: A control apparatus includes: a path calculation unit that calculates first and second paths sharing start and end nodes out of a plurality of nodes; a rule generation unit that generates a first rule for forwarding a packet along the first path and a second rule for forwarding a packet along the second path; and a rule transmission unit that sends the first and the second rules to at least one of the nodes, and has at least one of the nodes forward a packet according to either the first rule or the second rule.
