The present invention discloses a method for error connection and error prevention of service in an Automatically Switched Optical Network (ASON), to resolve the technical problems that the conventional method for error connection and error prevention cannot realize rapid automatic configuration and the efficiency is low and other problems. Through automatically completing the configuration of the error connection and error prevention information of the start node and the end node by the control plane, the present invention overcomes the defect that manual setting is error prone; it is rapid and simple to implement the interaction of the error prevention information between the start node and the end node by protocol exchange. Because the present invention can automatically complete the configuration of the error connection and error prevention information of the start node and the end node by the control plane, and can cite, when an error connection alarm occurs, the error prevent information of the original connection over a new connection of the service under the conditions of different error prevention policies, the present invention enhances the system availability and the service robustness to a great extent.
