<P>PROBLEM TO BE SOLVED: To implement overall optimization of a network by minimizing an electric switch path. <P>SOLUTION: A control device for photoelectricity composite type network nodes are connected with each other through transmission paths and have electric switches and optical switches, where a plurality of electric paths exchanged by the electric switch and a plurality of optical paths exchanged by the optical switch configure a transmission network. When detecting arrival of new traffic to the transmission network, the control device for photoelectricity composite type network nodes: requests establishment of a new electric path; calculates the new electric path on the basis of a traffic parameter and physical topology of the transmission network; integrates an existing electric path and the newly calculated electric path; performs overall optimization of all of the optical paths on the basis of the integrated result; and updates all electric paths, optical paths, and mapping relationship for integrating from the electric paths into the optical paths on the basis of the overall optimization result. <P>COPYRIGHT: (C)2013,JPO&INPIT |
