摘要
The present invention discloses a method and device for processing an alarm in a ring optical transport network. The method comprises detecting alarm information in the ring network in real-time, and when generation of only an working ODUk alarm in the ring network is detected, performing a switching process of a 1+1 protection protocol on services carried on a working channel on which an alarm is generated; in the event that one working ODUk alarm has existed in the ring network, when generation of an alarm at a protection ODUk corresponding to the working ODUk on which the alarm has been generated is also detected, or when an optical multiplexed segment layer alarm is generated in the ring network, triggering a switching process of a channel shared protection protocol. The device comprises an alarm detection module and a switching triggering module. The present invention can perform the 1+1
