    • 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。

    • A method for protecting a label switched path is disclosed. The method includes: setting, in a record_route object node list, interface classification identifications in record_route objects corresponding to interfaces of resource reservation protocol nodes respectively, and delivering the list downstream; when a downstream resource reservation protocol node receives the record_route object node list from upstream, finding, by the downstream resource reservation protocol node, a record_route object node corresponding to a last outgoing interface of a nearest outgoing interface in the record_route object node list according to the interface classification identifications, and setting next next hop protection for a corresponding label switched path according to a protection identification of the record-route object node. A system and device for protecting a label switched path are also disclosed. With the invention, an RSVP node may implement NNHOP protection for an upstream LSP correctly.
    • 公开了一种用于保护标签交换路径的方法。 该方法包括:在record_route对象节点列表中分别在与资源预留协议节点的接口相对应的record_route对象中设置接口分类标识,并将该列表下发; 当下游资源预留协议节点从上游接收到记录路由对象节点列表时,由下游资源预留协议节点根据所述记录路由对象节点列表中最近出站接口的最后输出接口对应的record_route对象节点 接口分类标识,并根据记录路由对象节点的保护标识为相应的标签交换路径设置下一个下一跳保护。 还公开了一种用于保护标签交换路径的系统和设备。 利用本发明,RSVP节点可以正确地为上游LSP实施NNHOP保护。
