Patent ID: 8868967

Claim:
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.
