TRANSMISSION APPARATUS, TEST METHOD, AND TRANSMISSION APPARATUS CONTROL PROGRAM

摘要

A transmission apparatus transmits/receives test frames to test connectivity between the transmission apparatus and another transmission apparatus to/from the other transmission apparatus at regular intervals. The transmission apparatus includes a frame length changing unit that changes a frame length, which is capacity of each of the test frames, at every transmission when the test frames are transmitted to the other transmission apparatus at the regular intervals; a reception determining unit that determines whether the test frames having changed frame lengths transmitted from the other transmission apparatus at the regular intervals have been received at the regular intervals; and a frame length calculating unit that calculates the frame length of the test frame that has not been received if the reception determining unit determines that the test frame has not been received.
