The invention provides a control device, a control system and a control method of photoelectric compound network nodes. The control device of photoelectric compound network nodes controls a plurality of photoelectric compound network nodes, which are connected through a transmission path and among which there are electrical switches and optical switches, and a plurality of electrical paths switched by the electrical switches and a plurality of optical paths switched by the optical switches constitute a transmission network. The control device of photoelectric compound network nodes requests that a new electrical path be created when finding that a new flow reaches, calculates the new electrical path according to flow parameters and the physical topology of the transmission network, converges the existing electrical paths and the new electrical path obtained through calculation, carries out global optimization on all the optical paths according to the result of the convergence, and updates all the electrical paths, the optical paths and the mapping relationship of the convergence from the electrical paths to the optical paths according to the result of the global optimization. |
