Wavelength Label Frame for Optical Node Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing configuration methods for ultra-100G optical transport systems are inefficient and prone to high error rates due to the sequential configuration of network managers across nodes, particularly when changes in modulation formats, subcarrier multiplexing, and spectrum occupation conditions occur, leading to low spectrum utilization efficiency.
Innovation Solution
A method where a sending node encapsulates configuration information in a wavelength label information frame, which is loaded onto an optical signal and sent directly to downstream nodes, allowing for adaptive configuration and reporting to a network manager, thereby bypassing sequential configuration through the network manager.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If configuration information is transmitted through a network manager to each node sequentially, then centralized control and management are achieved, but configuration efficiency decreases and error rate increases when system changes are required
Solution Approach 1:
The sending node autonomously generates and transmits configuration information to downstream nodes without requiring network manager intervention for each node. The receiving nodes automatically configure themselves based on the transmitted wavelength label information, enabling self-service configuration that eliminates manual sequential configuration while maintaining centralized control through the network manager's ability to initiate changes.
Solution Approach 2:
The configuration process is segmented into independent wavelength label information frames that can be transmitted and processed independently at each node. This segmentation allows parallel configuration of multiple nodes simultaneously, transforming the sequential configuration process into a parallel operation that significantly improves configuration efficiency.
2Ease of operation
If configuration information is transmitted through a network manager to each node sequentially, then centralized control is maintained, but configuration error rate increases due to the complexity of manual configuration
Solution Approach 1:
Downstream nodes automatically extract configuration information from the wavelength label information frame and self-configure based on the embedded parameters. This automated self-service process eliminates manual configuration errors and reduces the error rate by replacing error-prone manual operations with automated parsing and configuration execution.
Solution Approach 2:
The wavelength label information frame acts as an intermediary carrier that transports configuration information from the sending node to downstream nodes. This standardized intermediate format ensures accurate transmission of configuration parameters, reducing errors by providing a structured, machine-readable format that eliminates ambiguity in configuration data.
3Adaptability or versatility
If the system performs flexible grid spectrum optimization with changing spectrum occupation conditions, then spectrum utilization rate increases, but the configuration workload increases significantly
Solution Approach 1:
The wavelength label information frame includes dynamic parameters such as subcarrier multiplexing manner, signal rate, modulation format, and spectrum resource occupation that can be changed without altering the overall configuration mechanism. This allows the system to adapt to different spectrum conditions by simply modifying parameters within the standardized frame structure, enabling flexible optimization without increasing configuration complexity.
Solution Approach 2:
The wavelength label information frame serves multiple functions: it carries configuration information for downstream nodes, encodes spectrum resource occupation details, specifies modulation and multiplexing parameters, and enables adaptive reconfiguration. This multi-functional standardized frame reduces configuration workload by consolidating multiple configuration tasks into a single universal communication mechanism.
