To realize this object, the transmission apparatus includes a determining unit that determines, when a transmission apparatus receives a frame from each ring in a network including multiple rings in which a part of each ring is shared, whether failure information indicating that a failure has occurred in one of the rings is contained in one of the received frames. The transmission apparatus also includes a mapping unit that maps a frame that is determined by the determining unit to contain the failure information, onto a shared frame that is a frame used in a shared portion in the multiple rings. Accordingly, the process performed due to a failure recovery can be simplified.
