A PROTECTING METHOD AND DEVICE FOR ETHERNET TREE SERVICE |
摘要 |
A method and device for protecting Ethernet Tree (E-Tree) services are disclosed. An ID is configured for each branch of the E-Tree. The method includes: determining a branch that needs to perform switching; notifying the ID of the branch that needs to perform switching to a work E-Tree through a root UNI of a protect E-Tree; and switching data over the branch that needs to perform switching from the work E-Tree to the protect E-Tree according to the ID of the branch that needs to perform switching. In the embodiments of the present invention, because an ID is configured for each branch of the E-Tree, the branch corresponding to the ID may be triggered to perform protection switching as required, thus implementing branch switching.
