Embodiments of the present invention provide a 1+1 end-to-end bidirectional switching method, which implements a bidirectional switching function when a path is faulty and ensures that selective receiving paths are the same between a head end and a tail end, and therefore, requirements of a network application that imposes a stringent round-trip delay requirement are met and convenience is provided for daily maintenance of a network. The method includes: receiving, by a source node, candidate path information sent by a node that detects a fault; acquiring, by the source node, a first path according to the candidate path information, and switching a service to a data channel corresponding to the first path; and sending, by the source node, on the first path, information about the first path to a sink node, so that a node capable of 1+1 protection on the first path determines, according to the information about the first path, to switch the service to the data channel corresponding to the first path. |
