Method and Device for Realizing Optical Channel Data Unit Shared Protection Ring |
摘要 |
A method and a device for realizing an optical channel data unit (ODU) shared protection ring (SPRing) are disclosed. The method includes: first, receive an ODUj, wherein the ODUj carries an ODUi; then, perform de-multiplexing processing to obtain the ODUi from the ODUj; next, multiplex the ODUi to an optical channel data unit k (ODUk); meanwhile, keep monitoring the ODUk; and when the monitoring result that is obtained through monitoring the ODUk indicates that a failure has occurred, perform a switching on the ODUi; wherein i, j, k are integers equal to or larger than 0, k is larger than j, j is larger than i, and i, j, k are used to indicate different rates of respective optical channel data unit (ODU) signals. |

1. A method, comprising:
conducting path monitoring for a first optical channel data unit (ODU), and obtaining a monitoring result, wherein the first ODU is an ODUk; and in response to the monitoring result indicating that a failure occurred, performing a switching of a second ODU, wherein the second ODU is an ODUm that is carried by the ODUk, and m is smaller than k. |
