<p>A method, device, and system for traffic switching in Multi-Protocol Label Switching Traffic Engineering (MPLS TE) are disclosed. The method includes: transmitting traffic over a standby Label Switching Path (LSP) after detecting fault of an active LSP; detecting that the forwarding entries of all routers on the active LSP are delivered completely after the fault of the active LSP is rectified; and switching the traffic to the active LSP, and transmitting the traffic over the active LSP. The present invention ensures that the forwarding entries of all nodes on the active LSP are delivered completely, and prevents packet loss and traffic loss in the case of switching the traffic back from the standby LSP to the active LSP, thus improving the user experience and enhancing the network availability and stability.</p> |
