摘要
A method and a device for realizing an optical channel data unit (ODU) shared protection ring (SPRing) are disclosed by the present invention. The method includes: A first ODU of a first service transmitted in an optical line is taken as a protection granularity, where the first ODU is an ODUk that is directly multiplexed to the optical line; the first ODU is monitored, and a monitoring result is obtained; when the monitoring result indicates that a failure occurs, a switching is performed through cross of a second ODU of the first service, where the second ODU is an ODUm that is multiplexed to the first ODU, and m is smaller than or equal to k. Through the embodiments of the present invention, a protection switching speed may be accelerated.
