Abstract: A user network interface (UNI) path setting method includes advertising an attribute and state information of a TNA interface, and updating a database using information collected through the advertising, computing a path to a destination TNA address from a source TNA address satisfying UNI path setting parameter information included in a path message in consideration of an attribute and state information of the updated TNA interface/link when receiving a path setting request message from an operator, transmitting a path message to a destination through a network based on the computed path, and transmitting a reservation (RESV) message for UNI path generation to a source through the network when normally receiving, by the destination, the path message.

Abstract: Provided are a power-saving apparatus and method for multi-lane-based Ethernet, which allow a multi-lane-based Ethernet apparatus to improve energy-conserving efficiency while minimizing the deterioration of the performance of a network. The power-saving apparatus includes: a multi-lane communication unit configured to distribute an input communication packet between a plurality of transmission lanes, photoelectrically convert the input communication packet and transmit the photoelectrically-converted communication packet; a multi-buffer unit configured to comprise one or more buffers, store the input communication packet in each active buffer and transmit the input communication packet to the multi-lane communication unit; and a control unit configured to monitor the multi-buffer unit, compare the size of memory space in use of the multi-buffer unit with a predefined threshold and switch the one or more buffers to an active or inactive state based on the results of the comparison.
