GMPLS Link Configuration Automation via Node Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current GMPLS network management relies on manual and error-prone methods for configuring links, lacking a centralized system for network topology management and Link Management Protocol configuration, which is inefficient and prone to errors.
Innovation Solution
A method and apparatus for configuring links in a GMPLS network that involves determining link formation, sending link formation information to a link manager, receiving configuration information, and configuring the link automatically, utilizing link configuration elements in network nodes and a network management system to create and manage link records without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual node installation and manual link creation are used for network management, then configuration control is maintained, but the process becomes tedious and error-prone
Solution Approach 1:
The system enables automatic link configuration where network nodes autonomously detect link formation, generate link formation information, and trigger configuration processes without requiring manual intervention from operators. The Link Management Protocol automatically manages neighboring nodes and configures links based on detected physical connections.
Solution Approach 2:
The system performs preliminary detection of link formation through cable insertion detection and automatic generation of link formation information before the actual configuration process. This preliminary action includes detecting when a cable is inserted at a port and automatically initiating the configuration sequence.
2Stability of the object's composition
If centralized system configuration is used for Link Management Protocol, then network-wide coordination is achieved, but the system becomes complex and requires additional infrastructure
Solution Approach 1:
The configuration function is segmented between network nodes and the Link Management Protocol. Each network node locally detects link formation and generates link formation information, while the Link Management Protocol handles the coordination and configuration distribution. This segmentation reduces the burden on any single centralized system.
Solution Approach 2:
The Link Management Protocol acts as an intermediary between physical link detection and configuration execution. It receives link formation information from network nodes, coordinates the configuration process, and ensures consistent network-wide setup without requiring direct centralized control for every configuration detail.
3Productivity
If automatic link detection and configuration is implemented, then operator intervention is reduced and efficiency improves, but system complexity increases
Solution Approach 1:
Network nodes automatically detect when a cable is inserted at a port, generate link formation information containing endpoint identity information, and trigger the configuration process without operator intervention. This self-service capability enables rapid link configuration while distributing the complexity across multiple nodes rather than requiring a single complex centralized system.
