| 20100150163 | ETHERNET SWITCHING APPARATUS, AND METHOD FOR REDUCING POWER CONSUMPTION OF THE SAME - A method for reducing power consumption in an Ethernet switch is provided. The method includes: checking a state of packet data input through each of connection ports; detecting a connection port which has a packet rate lower than a predetermined reference value based on a result of the checking; and generating a data transfer control frame with respect to the connection port having the low packet rate and transmitting the generated data transfer control frame to an Ethernet apparatus connected to the corresponding connection port. Accordingly, a transmission line between the Ethernet switch and an Ethernet apparatus having the low to transmission rate is maintained in a low-power state, thereby reducing energy consumption in both Ethernet apparatuses. | 06-17-2010 |
| 20100162033 | ETHERNET APPARATUS CAPABLE OF LANE FAULT RECOVERY AND METHODS FOR TRANSMITTING AND RECEIVING DATA - An Ethernet apparatus for performing lane fault recovery is provided. An Ethernet apparatus capable of lane fault recovery includes a data transmitter using a backup lane in the transport link to transmit data intended to be transmitted via the faulty lane when at least one faulty lane is detected from the data transfer lanes, and a data receiver recognizing the data received via the backup lane as data transferred via the faulty lane when the faulty lane is detected. In an Ethernet apparatus having a multi-lane structure, a lane fault and faulty lanes can be accurately recognized while maintaining compatibility with a standard Ethernet apparatus. | 06-24-2010 |
| 20100329112 | ETHERNET DEVICE AND LANE OPERATING METHOD - An Ethernet device having multiple lanes and a method of operating the lanes are provided. In one general aspect, it is possible to allocate a dummy block to each of one or more lanes such that the lanes do not selectively participate in communications. In addition, on a receiving side, the dummy block can be removed from among the genuine data blocks to enable data to be decoded. In this case, an Ethernet device on a transmission side and an Ethernet device on a receiving side can exchange information of a lane to which the dummy block is allocated by use of a lane status message, and the lane status message may be based on a link fault message specified by Ethernet standards. | 12-30-2010 |
