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 by the present invention. 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 for realizing service data protection in an optical channel data unit (ODU) shared protection ring (SPRing), comprising:
receiving, an optical channel data unit j (ODUj), wherein the ODUj carries an optical channel data unit i (ODUi); performing de-multiplexing processing to obtain the ODUi from the ODUj; multiplexing the ODUi to an optical channel data unit k (ODUk); monitoring the ODUk; and performing a switching on the ODUi when the ODUk monitoring indicates that a failure has occurred; 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 indicate different rates of respective optical channel data unit (ODU) signals.
