    • A method, device, and system for traffic switching in Multi-Protocol Label Switching Traffic Engineering (MPLS TE) are disclosed. The method includes: transmitting traffic over a standby Label Switching Path (LSP) after detecting fault of an active LSP; detecting that the forwarding entry on the active LSP is delivered completely after the fault of the active LSP is rectified; and switching the traffic to the active LSP, and transmitting the traffic over the active LSP. The present invention ensures that the forwarding entry on the active LSP is delivered completely, and prevents packet loss and traffic loss in the case of switching the traffic back from the standby LSP to the active LSP, thus improving the user experience and enhancing the network availability and stability.
    • 公开了一种多协议标签交换流量工程(MPLS TE)中流量交换的方法,设备和系统。 该方法包括:在检测到活动LSP的故障后,通过备用标签交换路径(LSP)发送流量; 检测到活动LSP故障后的转发表项是否完整发送; 并将流量切换到活动LSP,并通过活动LSP发送流量。 本发明确保了主动LSP上的转发表项完全传递,在备用LSP切换到主动LSP的情况下,防止报文丢失,流量丢失,提高用户体验,提高网络可用性 和稳定性。
