ETHERNET SWITCHING APPARATUS AND METHOD FOR SAVING ENERGY THEREFOR

摘要

PURPOSE: An ethernet switching device and a method for reducing power consumption thereof are provided to reduce energy consumption without making complexity by minimizing packet transmission delay. CONSTITUTION: A plurality of connection ports is connected to each Ethernet device(20). A control part(100) includes a control frame generator(104) producing a data transmission control frame. The control frame generator transmits the data transmission control frame to the Ethernet device by producing the data transmission control frame about a connection port according to a state of packet data.
