Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to improve the efficiency of mapping content in a cell carrying service within traditional OTN frames, particularly with the adoption of FlexE technology which uses 66-bit code blocks.
Innovation Solution
A method and apparatus for mapping content involves determining a carrying position in the payload area of an OTN frame, identifying a sub-carrying unit, extracting content from a cell stream, and sequentially mapping this content into the sub-carrying unit, with the option to indicate idle sub-carrying units by specific content mapping.

Engineering Contradiction Analysis
1Productivity
If traditional mapping methods are used for cell carrying service in OTN frames, then the mapping process is simple, but the mapping efficiency is low
Solution Approach 1:
The patent divides the payload area of the OTN frame into multiple sub-carrying units, and divides the cell stream into multiple cell groups. Each sub-carrying unit independently carries a cell group, enabling parallel processing and improving mapping efficiency while maintaining manageable complexity through structured segmentation.
Solution Approach 2:
The patent performs preliminary determination of carrying positions and sub-carrying units before the actual mapping process. Cell streams are pre-organized into cell groups, and the mapping structure is pre-established, which streamlines the subsequent mapping operations and improves overall processing efficiency.
2Quantity of substance
If the OTN frame payload area is fully utilized for mapping, then the resource utilization is high, but the adaptability to varying cell stream speeds is reduced
Solution Approach 1:
The patent introduces a dynamic mapping mechanism where the number of sub-carrying units and their allocation can be adjusted based on the cell stream speed and traffic conditions. This allows the system to adapt to varying loads while maintaining high payload utilization by dynamically optimizing the mapping configuration.
Solution Approach 2:
The patent changes the mapping parameters (such as the number of sub-carrying units, cell group size, and carrying position allocation) according to the cell stream speed and traffic characteristics. This enables the system to optimize payload utilization for different traffic conditions without sacrificing adaptability.
3Ease of operation
If idle sub-carrying units are indicated by specific content mapping, then the idle status detection is simplified, but the mapping complexity increases
Solution Approach 1:
The patent uses specific content patterns (analogous to color changes) to indicate idle sub-carrying units. By assigning distinctive content markers to idle units, the system simplifies idle status detection and management while the structured approach to content mapping keeps the overall complexity manageable through standardized procedures.
