Abstract: A linear protection switching-based domain connecting method includes determining, by a protection interconnecting node, a user traffic transceiving path based on information on a presence or absence of defect in working paths and protection paths, generating working path control information and protection path control information based on information on the determined user traffic transceiving path and the information on the presence or absence of the defect in the protection paths, and transmitting the generated working path information to the working interconnecting node, and connecting two paths among the protection paths, and the connection path based on the protection path control information.
