[Problem] To provide a communication system, a communication method, and a control device that make it possible to resolve optimal paths while taking network resources and resources for packet-processing nodes into account. [Solution] This invention comprises the following: a plurality of network nodes (N1 through N5) provided with path-control functionality; one or more processing nodes (20a, 20b) that process incoming packets; and an upper-level control device (30) that sets paths for the respective network nodes by using network-load information collected from the network nodes and processing-load information collected from the processing node(s) to calculate optimal paths to said processing node(s). |
