Abstract
A method of MPLS network traffic switching is provided herein. The method includes these steps: receiving a message indicative of creating a new LSP successfully, and generating a new uplink forwarding entry and a new downlink forwarding entry according to the message; storing the new uplink forwarding entry, and configuring the new downlink forwarding entry; configuring the new uplink forwarding entry upon completion of configuring the new downlink forwarding entry; and forwarding the traffic according to the new uplink forwarding entry and the new downlink forwarding entry. By ensuring the sequence of processing the events in the traffic switching process, the method reduces the probability of traffic interruption in the traffic switching process. A network node device for implementing MPLS network traffic switching is also provided herein.
