METHOD AND SYSTEM FOR PREVENTING SERVICE MISCONNECTION IN ASON NETWORK Russian patent published in 2013 - IPC H04L12/24 

FIELD: radio engineering, communication.

SUBSTANCE: method of preventing service misconnection in an automatically switched optical network comprises the following steps: A) the control plane configures service error prevention information in a transport plane; B) upon detecting a misconnection, the transport plane sends a misconnection warning message to the control plane based on said service error prevention information; C) after receiving the described misconnection warning message, the control plane obtains a policy to prevent the service error resulting in the misconnection warning signalling, and performs the corresponding error prevention operation; wherein the described error prevention policy is a rerouting policy or a secure switching policy, and the error prevention information of the initial connection is referenced to in the new service connection.

EFFECT: high rate of configuring service error prevention information.
