Patent number: 8248917Abstract: The embodiments of the present invention provide a method and a system for implementing protection switching in Multi-protocol Label Switching (MPLS) network, the method includes: transmitting by a first Egress Label Switched Router (LSR) first probe packets to an Ingress LSR via a first Label Switching Path (LSP); switching by the Ingress LSR working traffic to a third LSP terminated at a second Egress LSR when the Ingress LSR does not receive the first probe packets. According to the embodiments of the present invention, the Ingress LSR may learn the failure of the Egress LSR according to the result of receiving the probe packets when a failure of the Egress LSR occurs, and switches the working traffic correspondingly. Moreover, the working LSP and protection LSP are not terminated at a same Egress LSR, but correspond to different Egress LSRs which greatly improves the security of the MPLS network.Type: GrantFiled: March 21, 2007Date of Patent: August 21, 2012Assignee: Huawei Technologies Co., Ltd.Inventor: Wenyang Lei
