CONTROL DEVICE, COMMUNICATION DEVICE, COMMUNICATION METHOD, AND PROGRAM

摘要

Provided is a control device that finely controls individual control target devices without being limited by the number of control target devices, monitoring frequency, and the like. A communication device selects control information from among a plurality of pieces of control information that matches received packets and that has a matching condition with the highest priority rank, and processes received packets on the basis of the selected control information. The control device is provided with: a control information generation unit that generates a plurality of pieces of control information for which at least a portion of the matching conditions overlap and the priority rank and processing contents differ between the pieces of information; and a control unit that sets the plurality of pieces of control information with regards to the communication device. In order to change the control information that has the highest priority rank among the plurality of pieces of control information, processing is carried out in the communication device on the basis of change conditions set in advance for each of the pieces of control information. Switching of the communication policy is performed through conversion of the priority rank.
