Abstract:
1. Transmission equipment that is used in a transmission system in which a plurality of paths are provided between the transmission equipment and correspondent equipment, the transmission equipment comprising: a measurement unit configured to measure respective transmission delays of the plurality of paths by using a frame transmitted between the transmission equipment and the correspondent equipment; a detector configured to detect a priority of an input packet; a selector configured to select a path for transmitting the input packet from among the plurality of paths; and a frame processing unit configured to transmit a frame onto which the input packet is mapped, to the correspondent equipment through a path selected by the selector, wherein the selector selects an alternative path for transmitting the input packet from among the plurality of paths based on the priority of the input packet detected by the detector and respective transmission delays of the plurality of paths measured by the measurement unit when a failure occurs in a path that has been selected by the selector.
