Automatic Optical Fiber Connection Discovery in ASON
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual configuration of optical fibre connections within network elements in ASONs is error-prone, labor-intensive, and costly, and hinders the transition from SPC to SC services due to the need for extensive manual setup and management.
Innovation Solution
A method and system for automatically discovering optical fibre connections within network elements, where a destination board sends a sextuple group message to an ASON if connected to a source board, and the ASON validates and stores the connection, eliminating the need for manual configuration and reducing maintenance efforts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual configuration of internal optical fibre connections is performed, then the ASON module can generate the total set of connections, but the process is error-prone and time-consuming
Solution Approach 1:
The system enables automatic discovery of internal optical fibre connections through message exchange between source and destination boards. The destination board autonomously determines connection status by receiving triple group messages from source boards and generates sextuple group messages to report connections to the ASON, eliminating the need for manual configuration and reducing both time and errors.
Solution Approach 2:
The invention implements a feedback mechanism where destination boards monitor incoming messages from source boards and report connection status back to the ASON through sextuple group messages. This continuous feedback loop enables automatic detection and validation of optical fibre connections, ensuring configuration accuracy without manual intervention.
2Ease of operation
If manual configuration of internal optical fibre connections is performed, then the routing topology can be established, but the effort and maintenance cost increase significantly
Solution Approach 1:
The system enables automatic discovery of internal optical fibre connections through message exchange between source and destination boards. The destination board autonomously determines connection status by receiving triple group messages from source boards and generates sextuple group messages to report connections to the ASON, eliminating the need for manual configuration and reducing both time and errors.
3Adaptability or versatility
If manual configuration is used for SPC service, then network management can control connections, but transition to SC service requires extensive reconfiguration
Solution Approach 1:
The automatic connection discovery mechanism enables the system to adapt to different service modes (SPC and SC) without requiring manual reconfiguration. The destination boards continuously discover and report connections through message exchange, allowing the ASON to dynamically adjust to service type changes while maintaining the same underlying connection management approach.

AI summary
A method, device and system for automatically discovering optical fiber connection within a network element are provided. In the method, a destination board determines whether it is connected with a source single board for the first time according to a triple group message received within a predefined period and sent by the source single board, and if yes, sends a sextuple group message generated based on its triple group message to an ASON, and stores the sextuple group message in a local database; otherwise, it sends the sextuple group message stored in the local database and corresponding to the triple group message, to the ASON when timing is reached; when receiving the sextuple group message and determining that the sextuple group message is not stored locally, the ASON detects validity of a connection corresponding to the sextuple group message, and locally stores the sextuple group message if the connection is valid, otherwise, displays connection error information to a user.
