Ethernet Header Compression With Selective Context and Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the 5G IIoT system, there is a pressing need for efficient header compression on Ethernet frames, which is not adequately addressed by existing technologies.
Innovation Solution
The method involves transmitting Ethernet frames with specific information in their headers to indicate whether context establishment and/or feedback transmission are required, allowing for selective header compression and reducing unnecessary computational and storage overheads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If header compression is performed on all Ethernet frames, then network efficiency is improved, but storage and computational overhead increase unnecessarily
Solution Approach 1:
The patent applies partial action by performing header compression only on selected Ethernet frames that require it, rather than all frames. The compressor determines whether compression is needed based on frame characteristics, and the decompressor only establishes context when necessary, reducing unnecessary storage overhead while maintaining network efficiency for frames that benefit from compression.
Solution Approach 2:
The patent implements local quality by applying different processing treatments to different Ethernet frames based on their specific characteristics. Some frames receive header compression while others do not, depending on whether they meet compression criteria. This selective approach optimizes storage usage by compressing only where beneficial rather than uniformly processing all frames.
2Measurement precision
If context establishment is performed for every Ethernet frame, then decompression accuracy is improved, but processing time and computational resources increase
Solution Approach 1:
The patent applies partial action by establishing context only for Ethernet frames that require decompression, not for all incoming frames. The decompressor checks whether a frame needs context establishment based on compression indicators, performing this computationally intensive operation only when necessary, thereby reducing processing time while maintaining accuracy for frames that require it.
3Reliability
If feedback transmission is performed for all compressed frames, then compression reliability is improved, but network overhead and transmission time increase
Solution Approach 1:
The patent applies partial action by transmitting feedback only for compressed Ethernet frames that require it, rather than for all compressed frames. The system determines whether feedback is necessary based on compression success and receiver needs, reducing network overhead from unnecessary feedback transmissions while maintaining reliability for frames where feedback is essential.

AI summary
A method for Ethernet frame transmission, a method for Ethernet frame reception, a compressor, and a decompressor are disclosed in the disclosure. The method includes transmitting, by a compressor, a first Ethernet frame to a decompressor, where a header of the first Ethernet frame carries first information, and the first information is used to indicate to the decompressor whether to perform context establishment, and/or, whether to perform feedback transmission.
