Abstract

When one link failure happens in BSHR/2 networks, it is possible to restore all traffics by following the ITU-T G.841 rules. However, when a node that is currently executing a ring switch receives a long-path ring bridge request for an higher priority, it shall drop its bridge and switch immediately, then enter full pass-through. Even through link connection between two nodes exists, it is impossible to restore the service. In this paper, when multi-link failures happen, the services through connected link can be restored by exchanging messages through DCC(Data Communication Channel). Partially reconstructing the ring map that is unable to restore services because of multi-link failures made it possible to restore these kinds of traffic pattenrs. This paper shows that the services through connected link can be restored by using proposed method.
