Optical Network Protection Path Grouping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In optical communication networks, managing protection paths across multiple nodes in a mesh topology is inefficient due to the need for individual message provisioning for each connection ID when a failure occurs, leading to potential delays and bottlenecks in data transmission.
Innovation Solution
Grouping connection IDs that share identical protection paths and resource trails under a single group identification, allowing a single message to provision all protection paths within the group upon detection of a failure, thereby reducing the complexity and time required for path switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual message provisioning is used for each connection ID when a failure occurs, then each connection can be managed independently, but the complexity and time required for path switching increases
Solution Approach 1:
The patent groups multiple connection IDs that share identical protection paths into a single group identified by a group ID. Instead of sending individual provisioning messages for each connection ID, the system sends a single message containing the group ID to provision all connections in the group simultaneously. This merging approach reduces the number of messages and simplifies the path switching process while maintaining independent management capability through the grouping mechanism.
2Reliability
If individual message provisioning is used for each connection ID, then detailed control over each connection is maintained, but delay times in provisioning protected paths increases
Solution Approach 1:
By merging multiple individual connection provisioning operations into a single group-based provisioning operation, the system reduces the total time required for path switching. The single message containing the group ID provisions all connections in the group simultaneously, eliminating the sequential delays that would occur with individual message processing for each connection ID.
3Loss of information
If individual provisioning messages are sent for each connection ID, then complete information about each connection is transmitted, but the volume of messages and processing overhead increases
Solution Approach 1:
The patent consolidates multiple individual connection information messages into a single message that contains the group ID. The grouping mechanism preserves complete connection information by organizing connections into groups based on shared protection paths and resource trails, allowing the system to transmit and process significantly fewer messages while maintaining full information completeness.
