For use in a communication system where communication is carried out by setting a packet handling operation (flow entry) in the nodes by a control device, the present invention provides a configuration in which statistical information may be collected at a desired information granularity level without increasing the control load of the control device. A node of the communication system includes a packet processing unit that processes a received packet according to a packet handling operation defining a matching rule and processing of a packet that matches the matching rule; and a statistical information recording unit that records statistical information on a packet according to a division different from the matching rule, and a statistical information collection device is provided that issues an instruction on a division, according to which the statistical information is to be recorded, to the node and collects the statistical information. |
