<p>A method, device and system of multi-protocol label exchange traffic engineering flow capacity switch are provided in the present invention embodiment, the method includes: after it is detected that the primary label exchange path is fault, flow capacity is transmitted in the backup label exchange path (404); when the fault of primary label exchange path is eliminated, it is detected that the forward table items of all of the routers in the primary label exchange path link are forwarded completely (405); it is switched to the primary label exchange path (405), the flow capacity is transmitted in the primary label exchange path. It is ensuredthat the forward table items of all the nodes of the whole link in the primary label exchange path are forwarded completely, when it is switched from the backup label exchange path to primary label exchange path in the present invention embodiment, it is realized that the packets and the flow capacity are not lose, so as to improve the usability and stability of user experience and the network.</p> |
