A method for establishing the path based on the change of the node address includes the steps of: a, changing the current active address of the node; b, setting the new address link transmission path; c, adding the first identifier which identifies that the new address link transmission path is the changed address transmission path and the second identifier which identifies the original address link transmission path which the new address link transmission path will replace to the new address link transmission path ;d, when the node judging that the new address link transmission path which passes through the node has the first identifier, it finds the cross connection corresponding to the original address link transmission path based on the second identifier attached to the address link transmission path, and mapping the cross connection to the new address link transmission path to complete the establish of the new address link transmission path. This invention avoids the switch loss of the service signal when switching between the original address link transmission path and the new address link transmission path.
