<p>A failure processing method, applying to a label switch path comprising the first node, the second node and at least the third node, wherein, the first node and the second node are adjacent nodes that occur communication breakdown, the first node restarts, the third node is the normal node which is closest to the first node, when the communication between the first node and the second node is broken, the third node maintains the control state information of the LSP during a period of time; when the first node and the second node resumes communication in the period of time, the first node, the second node and the third node resume the control state information of the LSP. The invention also comprises a failure processing system and a device on LSP. By the application of the invention, the LSP can be resumed reliably when several nodes on the LSP occur communication breakdown.</p> |
