Abstract:
1. A data relay apparatus that performs data transfer from one port to another port, the data relay apparatus comprising: a transmitting unit and a receiving unit provided for each port; a relay processing unit provided between the receiving unit at the one port and the transmitting unit at another port, and performing a data transfer relay process; and a function control unit that performs function control to limit a receive function of the receiving unit at the one port to reduce power consumption and thereafter allow the receive function to recover when a predetermined recovery condition is satisfied, the function control unit performing the function control based on an instruction when the instruction to perform the function control is received from a communication partner connected to the one port, whereas the function control unit notifies information about the function control to the communication partner when the data relay apparatus performs the function control itself independent of the instruction wherein in addition to the function control targeted for the receiving unit, the function control unit performs function control to limit a transmit function of the transmitting unit at a same port as the receiving unit to reduce power consumption, and to allow the transmit function to recover when the recovery condition is satisfied, wherein the function control unit measures a frequency of receiving data from the communication partner and performs the function control to limit a function when the measured frequency is less than or equal to a predetermined value.
