Abstract:
A method for implementing group protection in a Multiple Protocol Label Switching (MPLS) network disclosed in the present invention includes: monitoring a Label Switched Path (LSP) in an MPLS network; and performing a group protection switching when a failure is determined on an LSP of the working LSP group according to a monitoring result. In the present invention, a state of each monitored LSP of the working LSP group and the protection LSP group is monitored without merging LSPs of each LSP group. Moreover, as long a Signal Fail (SF) or a Signal Degrade (SD) is detected on an LSP of the working LSP group and no SF/SD is detected in the protection LSP group, an LSP group protection switching will be triggered, thereby easy the implementation of the LSP group protection.
