Automatic Node Configuration in OTN Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing OTN frame structure is cumbersome and prone to human error in configuring node working modes, especially as network complexity increases, and lacks support for more than six sub-domains due to limited overhead, making manual operation time-consuming and inefficient.
Innovation Solution
A method and system for automatically configuring node working modes in the SM, PM, and TCM layers based on node position, using a network management device to determine and send working mode information to a network element proxy device, which configures the modes, including transparent, monitoring, and operation working modes, and utilizes a reserved byte to support more than six sub-domains by extending the TCM layer overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual configuration of node working modes is performed according to configuration standard rules, then configuration accuracy can be maintained, but operation time increases and human error occurs easily as network complexity increases
Solution Approach 1:
The system enables automatic configuration of node working modes through the network management device that autonomously determines and configures SM, PM, and TCM layer modes based on node position, eliminating the need for manual configuration operations while maintaining configuration accuracy
Solution Approach 2:
The manual mechanical configuration process is replaced by an automated electronic system that uses network management devices to automatically determine node positions and configure appropriate working modes, substituting human operators with intelligent algorithms
2Reliability
If the TCM overhead structure is used according to present standard, then standard compliance is maintained, but support for more than six sub-domains is limited due to no spare reserved byte
Solution Approach 1:
The system extends the TCM layer functionality by utilizing the reserved byte (another dimension of the overhead structure) to enable support for more than six sub-domains, effectively adding capacity without violating the standard TCM overhead format
Solution Approach 2:
The system changes the utilization parameter of the TCM overhead by activating the previously unused reserved byte, thereby increasing the sub-domain identification capacity from 6 to more than 6 while maintaining standard compliance
3Ease of manufacture
If configuration is limited to only TCM layer, then implementation simplicity is maintained, but SM and PM layer working modes cannot be configured
Solution Approach 1:
The network management device is designed to perform multi-functionality by configuring working modes across three layers (SM, PM, and TCM) simultaneously, making the system universal and adaptable to different monitoring requirements across multiple protocol layers
