Flexible Ethernet Data Stream Sequence Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In flexible Ethernet systems, the transmission of configuration interaction maps to identify the sequence of physical connections in a physical connection group results in redundant information and low transmission efficiency due to the overhead required for sequence identification.
Innovation Solution
The method involves transmitting configuration status information, including identifiers of each physical connection and its adjacent connection, within the data stream, allowing the receiver to restore the sequence relationship using local adjacency information, thereby reducing overhead and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple configuration interaction maps are transmitted in the overhead area to identify the sequence of physical connections, then the receive end can restore the data stream correctly, but much redundant information is transmitted and resources in the overhead area are wasted
Solution Approach 1:
The patent extracts only the essential sequence identification information from the complete configuration interaction maps. Instead of transmitting full maps, it transmits simplified sequence indication information that contains only the necessary data for identifying the sequence of physical connections, thereby removing redundant information while maintaining restoration accuracy
Solution Approach 2:
The configuration information is segmented into essential sequence identification elements and non-essential redundant elements. Only the essential sequence indication information is transmitted in the overhead area, while other redundant configuration details are omitted, reducing overhead resource consumption
2Reliability
If multiple configuration interaction maps are transmitted to identify the sequence of physical connections, then the receive end can restore the data stream, but the transmission process takes a long time resulting in low transmission efficiency
Solution Approach 1:
The patent extracts and transmits only the critical sequence indication information needed for data stream restoration, eliminating the time-consuming transmission of redundant configuration map data. This selective information transmission significantly reduces the overhead transmission time while maintaining the ability to correctly restore the data stream sequence
Solution Approach 2:
Instead of transmitting complete configuration interaction maps (excessive action), the patent transmits only the partial information necessary for sequence identification. This partial transmission approach achieves the minimum required functionality with reduced time overhead, improving transmission efficiency

AI summary
A method for transmitting a data stream in a flexible Ethernet, where the method includes obtaining a to-be-transmitted data stream, allocating the data stream to N physical connections according to a sequence of the N physical connections in a physical connection group in order to obtain N sub-streams respectively corresponding to the N physical connections, and transmitting the N sub-streams using the N physical connections, where a sub-stream transmitted over each physical connection includes configuration status information of each physical connection, and the configuration status information includes an identifier of each physical connection and an identifier of a physical connection adjacent to each physical connection in the physical connection group. The method reduces, in a data stream transmission process, overheads required for identifying a sequence of all the physical connections in the physical connection group and improves transmission efficiency.
