FlexO Service Mapping Across PHY Links for Lower Logic Complexity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The FlexO transmission method faces high mapping complexity and high occupancy of logical resources due to the binding of multiple PHY links, which complicates service transmission and resource utilization.
Innovation Solution
A method and device that map customer service data into N FlexO frames on M PHY links, ensuring the same number of cells and cell locations across each PHY link, reducing complexity and resource occupancy by logically merging the frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple PHY links are bound to carry large bandwidth service, then service capacity is improved, but mapping complexity and logical resource occupancy increase
Solution Approach 1:
The service data is segmented into multiple ODUflex containers, each with a standardized structure. These containers are then independently mapped to different PHY links, dividing the complex mapping task into manageable segments that can be processed in parallel, thereby reducing overall mapping complexity while maintaining high service capacity
Solution Approach 2:
The patent introduces a new dimensional approach by defining time slots within FlexO frames as an additional layer of organization. Services are mapped to specific time slots rather than directly to PHY links, creating a two-dimensional mapping structure (time slot × PHY link) that simplifies the mapping process and reduces logical resource occupancy
2Adaptability or versatility
If ODUflex is mapped to time slot of any PHY link in FlexO frame, then service transmission flexibility is improved, but implementation complexity and logical resource occupancy increase
Solution Approach 1:
The patent applies local quality by allowing different time slots within the same FlexO frame to have different service mappings. Each time slot can be independently configured for specific services, providing local flexibility without requiring complex global remapping operations. This enables adaptive service transmission while maintaining simplified implementation through standardized slot structures
Solution Approach 2:
The patent establishes preliminary action by pre-defining the FlexO frame structure with standardized time slots before service mapping. This predetermined framework allows services to be mapped to predefined slots without requiring complex real-time decisions, thereby maintaining transmission flexibility while reducing implementation complexity and logical resource requirements

AI summary
Provided are a service transmission method and device using a FlexO, equipment and a storage medium. The method includes: customer service data is mapped into N FlexO frames on M Physical Layer links of a FlexO transmission group, and then the N FlexO frames are sent through the FlexO transmission group; and a receiving end sequentially extracts the customer service data from the N FlexO frames. The FlexO transmission group comprises M PHY links. The customer service data occupies the same number of cells in the FlexO frame of each PHY link, and cell locations of the occupied cells are the same. A set of logic is used to directly map the customer service data into the N FlexO frames on the M PHY links of the FlexO transmission group, so as to minimize complexity and logical resources needing to be occupied.
