Abstract
Examples of the present disclosure provide a dual-homing protection method and device. In the dual-homing protection method, a forwarding item synchronizing channel and a data transfer channel are established between two Provider Edge (PE) devices in a dual-homing node, a Pseudo Wire (PW) and a Label Switched Path (LSP) protection group bearing the PW are established between a network side peer PE device and the two PE devices in the dual-homing node, which are taken as a logical device, so as to implement LSP protection within a network. The present disclosure may enable the protection within a network to be independent of access link protection. Subsequently, the management is simple.
