摘要： A label switching router (LSR) and a method of switching data traffic to a predefined backup traffic path by the LSR in an MPLS (multi-protocol label switching) network. The LSR, upon detection of failure of a protected path during an LDP session, maintains an LDP session and forwards data traffic via the backup traffic path according to a forwarding table. The forwarding table contains logical output interface information including an outgoing label, a logical output interface, and the next hop of the predefined backup path.

摘要： A Pseudo Wire (PW) switching method applied to a MPLS L2VPN comprising U-PE devices and N-PE devices includes checking, by an N-PE device, connectivity of a main U-PW and a backup U-PW between the N-PE device and a U-PE device and connectivity of N-PWs between the N-PE device and other N-PE devices. When one of the main U-PW and the backup U-PW is detected to have failed, transmitting, by the N-PE device, a MAC address clear command through an N-PW in a VSI to which the failed U-PW belongs, and clearing, by an N-PE device receiving the MAC address clear command, MAC addresses associated with the N-PW for transmitting the MAC address clear command in the VSI; and when one of the N-PWs is detected to have failed, transmitting a traffic rerouting command through a U-PW in a VSI to which the failed N-PW belongs and performing U-PW switching.
摘要翻译：应用于包含U-PE设备和N-PE设备的MPLS L2VPN的伪线（PW）交换方法包括：通过N-PE设备检查主U-PW和备用U-PW之间的连通性， PE设备和U-PE设备以及N-PE设备与其他N-PE设备之间的N-PW的连通性。当检测到主U-PW和备用U-PW之一失败时，N-PE设备通过VSI中的N-PW发送MAC地址清除命令，失败的U-PW所属的VSI 并且由接收到MAC地址清除命令的N-PE设备清除与所述N-PW相关联的用于在所述VSI中发送所述MAC地址清除命令的MAC地址; 当检测到其中一个N-PW发生故障时，通过故障N-PW所属的VSI中的U-PW发送流量重路由命令，并执行U-PW切换。

摘要： Protection switching in a multi-protocol label switching (MPLS) ring network with a protection label switch path that is shared by multiple working label switch paths may include receiving a packet intended for transmission towards a disconnected adjacent node on a working label switch path, and adding, to the received packet, a protection label and a merge label. The merge label may uniquely identify the working label switch path on which the packet is received. The packet may be transmitted on the protection label switch path.
摘要翻译：具有由多个工作标签交换路径共享的保护标签交换路径的多协议标签交换（MPLS）环网中的保护倒换可以包括接收旨在向工作标签交换路径上的断开连接的相邻节点传输的分组，以及向接收到的分组添加保护标签和合并标签。合并标签可以唯一地标识接收到分组的工作标签交换路径。分组可以在保护标签交换机路径上传输。

摘要： According to an example, a MPLS ring protection switching method is applied to each node in an MPLS TP ring. In the method, an MPLS forwarding table entry configured for a working LSP and an MPLS forwarding table entry configured for a backup LSP of the working LSP are added into a first table, an MPLS forwarding table entry formed by cross connecting the working LSP and the backup LSP is added into a second table, a packet is received, the first table is searched when the node is in a normal forwarding state, and the packet is forwarded by using an MPLS forwarding table entry in the first table, the second table is searched when the node device is in a protection forwarding state, and the packet is forwarded by using an MPLS forwarding table entry in the second table.
