Data Frame Timeslot Signaling for Lower-Overhead Optical Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical communication systems face challenges in managing overheads during normal transmission and bandwidth adjustment, leading to complex processing and reduced system transmission performance, especially for private line services requiring flexible bandwidth.
Innovation Solution
A data transmission method and apparatus that defines a first indication field and a second indication field in the overhead area of a data frame to indicate the status and association relationship of a first timeslot, simplifying overhead design and improving transmission performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional overhead management methods are used during normal transmission and bandwidth adjustment, then system compatibility is maintained, but overhead complexity increases and transmission performance deteriorates
Solution Approach 1:
The patent merges the functions of indicating timeslot status and indicating service-timeslot association into a single unified overhead structure. The first indication field and second indication field work together in a coordinated manner, where the first field indicates timeslot status (occupied, idle, added, or removed) and the second field provides the specific association information, thereby reducing overall overhead complexity while maintaining transmission reliability.
Solution Approach 2:
The overhead structure is segmented into distinct functional fields: the first indication field for status indication and the second indication field for association relationship indication. This segmentation allows each field to perform its specific function efficiently, reducing the complexity of overall overhead management during both normal transmission and bandwidth adjustment operations.
2Measurement precision
If detailed overhead information is provided for each timeslot status change, then transmission accuracy is improved, but overhead size increases and processing efficiency decreases
Solution Approach 1:
The patent applies partial action by using indication fields that only provide the necessary level of detail for timeslot status and association information. Rather than providing complete exhaustive information for every possible timeslot state, the first and second indication fields provide just sufficient information to accurately track timeslot status changes and service associations, thereby maintaining precision while minimizing overhead size.
3Adaptability or versatility
If separate overhead mechanisms are used for normal transmission and bandwidth adjustment, then specific functionality for each scenario is achieved, but system complexity increases and processing time increases
Solution Approach 1:
The overhead structure with first and second indication fields serves multiple functions universally: it handles normal transmission by indicating occupied and idle timeslot states, and simultaneously handles bandwidth adjustment by indicating added and removed timeslot states. This multi-functional design eliminates the need for separate overhead mechanisms for different scenarios, thereby reducing processing time while maintaining adaptability to various transmission conditions.
Data Source
AI summary
In a data transmission method, a transmitter device obtains service data; maps the service data to a data frame; and sends the data frame to a receiver device. The data frame includes an overhead area and a payload area, the overhead area includes a first indication field and a second indication field, the first indication field indicates a status of a first timeslot in the payload area, and the second indication field indicates an association relationship between the first timeslot and the service data.
