NETWORK SWITCHING DEVICE, NETWORK SWITCHING SYSTEM, AND METHOD OF CHANGING POWER STATE OF NETWORK SWITCHING DEVICE

摘要

A first network switching device communicates to and from a second network switching device different in at least one of a device configuration and a device performance. The network switching device has at least one of plurality of network interface units and packet forwarding unit which is a power state control subject. A power state control unit of the first network switching device transmits, in order to change the power state of the second network switching device, a forwarding performance notification including the forwarding performance of a power state control subject after the change to the second network switching device.
