    • 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.
    • 本文提供了MPLS网络流量切换的方法。 该方法包括以下步骤:成功接收表示创建新LSP的消息,根据该消息生成新的上行转发表项和新的下行转发表项; 存储新的上行转发表项,配置新的下行转发表项; 配置新的下行转发表项后,配置新的上行转发表项; 并根据新的上行转发表项和新的下行转发表项转发流量。 通过确保流量切换过程中处理事件的顺序,该方法降低了流量切换过程中流量中断的概率。 本文还提供了一种用于实现MPLS网络流量交换的网络节点设备。
