Automatic Shared Risk Link Group Generation for IP+ Optical Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual configuration of Shared Risk Link Groups (SRLGs) in IP+ optical collaboration scenarios is inefficient, leading to high maintenance workload and instability in network topology due to frequent changes, as it relies on human judgment and cannot keep pace with real-time dynamic changes in the network.
Innovation Solution
A method and apparatus for automatically generating and updating SRLG values by analyzing paths in the service layer and optical domain, reducing the number of SRLGs and stabilizing network topology through a calculation unit, analysis unit, and storage unit, which determines coincident paths and updates SRLG values accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual configuration of SRLG values is used, then configuration flexibility is maintained, but maintenance workload increases and configuration accuracy decreases
Solution Approach 1:
The system performs automatic SRLG value configuration through the calculation unit that independently computes SRLG values based on path coincidence analysis, eliminating the need for manual operator intervention and reducing maintenance workload while improving configuration accuracy
Solution Approach 2:
The manual mechanical configuration process is replaced by an automated calculation system that uses path information analysis and coincidence detection algorithms to automatically determine and update SRLG values, transitioning from human-operated to system-operated configuration
2Stability of the object's composition
If manual configuration of SRLG values is used, then human judgment can be applied, but network topology stability deteriorates due to frequent changes
Solution Approach 1:
The calculation unit continuously monitors path information and dynamically adjusts SRLG values based on real-time network conditions, creating a feedback mechanism that maintains network topology stability while adapting to changes without requiring frequent manual reconfiguration
Solution Approach 2:
The system pre-calculates SRLG values based on path coincidence analysis before network changes occur, allowing proactive configuration that prevents topology instability rather than reacting to changes after they occur
3Productivity
If automatic generation of SRLG values is implemented, then configuration efficiency improves, but system complexity increases
Solution Approach 1:
The calculation unit serves multiple functions including path information analysis, coincidence detection, SRLG value computation, and database updates, consolidating what could be separate complex systems into a single multi-functional component that improves efficiency without proportionally increasing overall system complexity
