Configurable Lane Mapping for Muxponder Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current optical networking systems with CMIS standard configurations have fixed lane mapping, which limits flexibility and scalability, particularly in point-to-multi-point networks, as they require physical connections for each host lane group and cannot dynamically map data traffic to non-matching lanes.
Innovation Solution
The implementation of a configurable lane mapping system for muxponder modules in optical transport networks, allowing dynamic host lane mapping through an anchor muxponder module and configured muxponder modules with digital cross-connects and mapping tables, enabling flexible routing of traffic streams based on service identification codes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fixed lane mapping is used according to CMIS standard, then data routing is simplified with direct host lane to host lane mapping, but network flexibility and scalability are reduced requiring physical connections for each host lane group
Solution Approach 1:
The patent introduces a mapping table as an intermediary component between the optical receiver and host lanes. This mapping table stores configurable mappings that allow host lanes to be dynamically associated with media lanes without requiring fixed physical connections. The mapping table acts as a mediator that decouples the rigid one-to-one correspondence of fixed mapping while maintaining simple data routing through lookup operations.
Solution Approach 2:
The patent implements dynamic lane mapping where the mapping table can be reconfigured at runtime based on network conditions and requirements. Unlike fixed mapping where host lane n always maps to host lane n, the configurable mapping allows host lanes to be dynamically assigned to different media lanes and host lane groups, enabling the system to adapt to changing network topologies and traffic patterns.
2Reliability
If fixed physical connections are established for each host lane group, then reliable data transmission is ensured, but device complexity and scalability are increased
Solution Approach 1:
The patent makes the optical receiver universally applicable to multiple host lane groups through configurable lane mapping. Instead of requiring dedicated physical connections for each host lane group, a single optical receiver can serve multiple host lane groups by dynamically configuring the mapping table. This multi-functionality reduces the number of physical connections needed while maintaining reliable data transmission through proper signal routing.
Solution Approach 2:
The patent uses mapping table entries as virtual copies that represent logical connections between media lanes and host lanes. Instead of establishing physical connections for each mapping relationship, the system creates logical copies through mapping table entries that can be configured and reconfigured as needed. This virtualization approach reduces physical connection complexity while maintaining transmission reliability.
3Adaptability or versatility
If dynamic host lane mapping is implemented with mapping tables and digital cross-connects, then network flexibility and scalability are improved, but device complexity increases
Solution Approach 1:
The patent pre-configures mapping tables with default mappings and establishes the mapping structure in advance. This preliminary action allows the system to operate with simple default configurations while retaining the capability to dynamically reconfigure mappings when needed. The pre-established mapping framework reduces the complexity of dynamic reconfiguration by providing a ready-made structure that can be modified through simple table updates rather than complex routing changes.

AI summary
Disclosed herein are methods and systems for dynamically configuring a muxponder. One exemplary system may be provided with a muxponder module deployed in an optical network, the muxponder having an optical receiver, a first and a second electrical port, a demultiplexer having a built-in digital cross-connect, and a processor accessing a mapping table to assign traffic streams associated with a first service identification code to a first and a second host lane of the first electrical port, traffic streams associated with a second service identification code to a third and a fourth host lane of the second electrical port, and having logic to control the digital cross-connect to route a first and a second traffic stream to the first electrical port based on the first service identification code, and a third and a fourth traffic stream to the second electrical port based on the second service identification code.
