Method and system for connection-error handling of service in an automatically switched optical network

摘要

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

1. A method for connection-error handling of service in an Automatically Switched Optical Network (ASON), comprising:
A: a control plane configuring service error handling information for a transport plane; B: the transport plane reporting connection error alarm information to the control plane after detecting a connection error according to the service error handling information; C: the control plane acquiring, after receiving the connection error alarm information, an error handling policy of a service in which a connection error alarm is generated, and performing a corresponding error handling operation; wherein the service error handling information refers to a path trace byte, the control plane setting a sending value and an expected value when configuring the path trace byte, comprising: for a one-way service, the sending value is set in a sending direction of the start node of the service, and the expected value is set in a receiving direction of the end node of the service; where, the sending value is the same as the expected value; for a two-way service, the sending value is set in the sending directions of the start node and the end node of the service; the expected value is set in the receiving directions of the start node and the end node of the service; where, the sending value is the same as the expected value.
