Transmission equipment (1) in which, when a frame is received from a network, an output physical port is decided by a path deciding section (14) and a corresponding output logical port is decided by an output physical port deciding section (15). The frame is outputted to the output physical port, and when following received frames are successively transmitted, an output physical port number, to which each frame is outputted, is incremented by a port number increment section (18) each time a frame is transmitted, and a destination to which the frame is outputted is switched among output physical ports.
