Muxponder Host Lane Mapping for Point-to-Multi-Point Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The fixed mapping in current CMIS configurations limits dynamic configuration of muxponder modules, requiring physical optical ports for each host lane group connection and preventing data traffic from being mapped to non-matching lanes, which is inflexible and inefficient in point-to-multi-point networks.
Innovation Solution
Implementing dynamic host lane mapping systems and methods for muxponder modules, allowing network operators to map host lanes dynamically between network elements using anchor and configured muxponder modules with optical transmitters, receivers, digital cross-connects, and processors to route traffic streams based on calculated carrier frequencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fixed mapping is used in CMIS configuration, then device complexity is reduced and ease of operation is improved, but adaptability and versatility deteriorate
Solution Approach 1:
The patent implements dynamic host lane mapping that allows the mapping configuration to change based on operational needs. The system transitions from static fixed mapping to dynamic configurable mapping, enabling the network to adapt lane assignments in response to varying traffic patterns, module failures, or reconfiguration requirements while maintaining operational simplicity through automated management.
Solution Approach 2:
The invention changes the mapping parameter from fixed to configurable, allowing the host lane to media lane correspondence to be modified through software control. This parameter change enables the system to adapt to different network topologies and operational scenarios without requiring physical reconfiguration, thereby improving versatility while maintaining ease of operation through centralized management.
2Device complexity
If fixed physical mapping is implemented, then device complexity is reduced, but adaptability deteriorates and loss of time increases due to inability to respond to problems
Solution Approach 1:
The system introduces dynamic reconfigurability to the lane mapping function, allowing real-time changes in mapping relationships. This enables the network to respond to failures, optimize performance, and adapt to changing requirements without requiring physical reconfiguration or complex manual intervention, thus maintaining low device complexity while dramatically improving adaptability.
Solution Approach 2:
The patent incorporates feedback mechanisms that monitor network conditions, module status, and traffic patterns, then automatically adjust lane mappings in response. This feedback-driven approach enables the system to adapt to problems such as module failures or performance degradation by dynamically reconfiguring mappings, eliminating the need for manual intervention while maintaining operational simplicity.
3Adaptability or versatility
If dynamic host lane mapping is implemented, then adaptability and versatility are improved, but device complexity increases
Solution Approach 1:
The patent introduces a lane mapping manager as an intermediary component that handles the complexity of dynamic mapping configuration. This manager abstracts the complex mapping logic from the underlying hardware and provides a simplified interface for configuration and control, thereby enabling advanced adaptability while containing device complexity through modular architecture and centralized management.
4Ease of operation
If fixed mapping is used, then ease of operation is improved, but loss of time increases due to inability to dynamically reconfigure
Solution Approach 1:
The system transitions from static to dynamic mapping, enabling real-time reconfiguration in response to network conditions, failures, or optimization opportunities. This dynamic capability eliminates the time loss associated with manual reconfiguration or fixed mappings, while the automated management processes maintain ease of operation through centralized control and simplified interfaces.
Solution Approach 2:
The patent implements preliminary configuration and planning capabilities that prepare mapping configurations in advance based on predicted needs or pre-planned scenarios. This allows the system to quickly respond to events by activating pre-prepared configurations, thereby reducing response time while maintaining operational simplicity through automated execution of pre-planned actions.
