Data Packet Header Processing Mode Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In packet-oriented communication networks, all network nodes process data packets extensively, leading to unnecessary energy consumption, as they perform complex signal processing to evaluate destination addresses, even though only the intended receiver node needs to fully process the packet.
Innovation Solution
Implementing separate transmission and reception modes for data packet headers and payloads, using a simpler mode for headers to reduce processing complexity and energy consumption, while reserving more complex processing for intended receiver nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all network nodes process the entire data packet with complex signal processing, then the destination address can be evaluated at the data link layer, but energy consumption increases unnecessarily
Solution Approach 1:
The patent segments the data packet into two distinct parts: a header processed with a first (simpler) mode and a payload processed with a second (complex) mode. This segmentation allows receiving nodes to process only the header to evaluate destination addresses, avoiding unnecessary processing of the entire packet by nodes that are not the intended recipients.
Solution Approach 2:
The patent applies different processing qualities to different parts of the data packet. The header receives simplified processing with fewer processing steps, while the payload receives full complex processing only at the intended destination node. This local differentiation of processing quality enables energy savings at intermediate nodes while maintaining reliable destination address evaluation.
2Loss of information
If complex signal processing is performed on the entire data packet, then complete information is available for further processing, but processing complexity increases
Solution Approach 1:
The patent divides the data packet processing into two segments: header processing using a first mode with fewer processing steps and payload processing using a second mode with more processing steps. This segmentation ensures that essential control information in the header is processed efficiently by all nodes, while complete information availability for the payload is maintained only at the destination node.
Solution Approach 2:
Different processing complexities are applied locally to different packet components. The header is processed with simplified algorithms suitable for all receiving nodes, while the payload receives full complex processing only at the intended destination. This local quality differentiation reduces overall processing complexity while maintaining necessary information availability.
3Ease of operation
If uniform processing mode is used for header and payload, then processing is consistent, but energy efficiency is reduced
Solution Approach 1:
The patent implements local quality differentiation by applying a first processing mode to the header and a second processing mode to the payload. The header processing mode is designed with fewer processing steps for energy efficiency, while the payload processing mode provides complete processing capability. This approach maintains processing consistency within each mode while improving overall energy efficiency through mode differentiation.
Solution Approach 2:
The patent introduces dynamic processing mode selection based on the data packet component being processed. Receiving nodes dynamically switch between first mode (for header/destination address evaluation) and second mode (for payload processing at destination). This dynamic adaptation enables energy-efficient operation at intermediate nodes while ensuring complete processing at the destination node.

AI summary
The invention relates to a method for processing at least one data packet (78, 156) which comprises a first header (82, 158) and a payload (100, 160), wherein the first header (82, 158) is processed by a first mode and the payload (100, 160) is processed by a second mode, wherein a number of processing steps (172, 174) for carrying out the second mode is greater than a number of processing steps (168, 170) for carrying out the first mode, the two modes being performed separately from one another.
