The method includes: when the bidirectional forwarding detection (BFD) state of a Pseudo Wire (PW) is DOWN, the Provider Edge (PE) disenabling the Ethernet Operation, Administration and Maintenance (OAM) function of a port connected with a Customer Edge (CE); and the CE which has started a master and standby link switching function switching the service traffic to a standby link. The invention also provides corresponding apparatus and system. The invention reduces the influence of network failure on the service, decreases service unavailable probability and improves the service reliability."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method, apparatus and system for dual-homing protection switching","description":"The invention discloses a method for dual-homing protection switching.
