    摘要： Two transmission devices connected to a link in which a failure occurs turn back a ring. Other transmission device changes a transmission ring of an NNI packet which is a UNI packet whose transmission source is its own transmission device and which had been transmitted through the link before the failure occurs to have a reverse direction. In addition, each transmission device, upon receiving an NNI packet whose transmission destination NNI address is one or any one of a plurality of NNI addresses applied to its own transmission device, outputs the packet to a self-owned tributary port irrespectively of whether it is sent through an inner ring or an outer ring.
