Switch Control Command Processing for Network Data Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In optical fiber transmission networks, the Automatic Protection Switching (APS) protocol fails to maintain data consistency between network devices and managers due to the discarding of switch control commands without informing users about priority relationships, leading to manual queries and inconsistencies.
Innovation Solution
A method and apparatus that discard switch control commands when trigger information has higher priority and report these discarded commands to a control system, ensuring automatic deletion and maintaining data consistency without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network device automatically discards switch control commands with lower priority according to APS protocol, then the network protection switching reliability is improved, but the data consistency between network device and network manager deteriorates
Solution Approach 1:
The network device sends a notification message to the network manager when discarding a switch control command due to higher priority trigger information. This feedback mechanism ensures the network manager is informed of the command status change, maintaining data consistency between the network device and network manager while preserving the automatic protection switching functionality.
2Productivity
If the network device discards switch control commands without notifying the network manager, then the device operation speed is improved, but the ease of operation deteriorates
Solution Approach 1:
The system provides automatic notification feedback to the network manager when commands are discarded, eliminating the need for manual queries. This maintains fast automatic operation while improving ease of operation by keeping the network manager informed of the current command status.
3Measurement precision
If manual query is required to check switch control command status, then the measurement precision of command status is improved, but the loss of time increases
Solution Approach 1:
The network device proactively sends notification messages to the network manager before or at the moment a switch control command is discarded. This preliminary action eliminates the need for subsequent manual queries by the network manager, reducing time loss while maintaining accurate command status information.

AI summary
The present invention provides a method for processing a switch control command for solving the problem that consistency of data of the network device and the network management is unable to be kept in the process of processing the switch control command in the prior art. This method includes: when a priority of obtained trigger information is higher than a priority of a switch control command, discarding the switch control command (103); and reporting the discarded switch control command to a control system which manages the network device (104). The present invention further provides an device for processing a switch control command.
