Selective Packet Header Parsing to Cut Re-Encapsulation Delay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data packet processing methods involve sequential parsing and encapsulation of all headers, leading to increased parsing and re-encapsulation delays due to unnecessary processing of unmodified headers.
Innovation Solution
A data packet processing method that selectively parses and modifies only the necessary headers, avoiding layer-by-layer processing and encapsulation, by determining and parsing up to a specific header based on predefined fields.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sequential parsing and encapsulation of all headers is performed, then complete processing of data packet headers is ensured, but parsing delay and re-encapsulation delay increase
Solution Approach 1:
The patent extracts only the necessary headers that need to be modified from the complete header stack. Instead of processing all N layers of headers sequentially, the system identifies and processes only the specific header layers that require modification, eliminating unnecessary processing of unchanged headers and thereby reducing parsing and re-encapsulation delays while maintaining complete processing of required headers
Solution Approach 2:
The patent applies partial action by performing parsing and encapsulation operations only on the portion of headers that actually need modification rather than processing the entire header stack. This selective approach processes only K layers out of N total layers, where K < N, achieving the required processing completeness with reduced operational overhead
2Manufacturing precision
If layer-by-layer parsing processing is performed on all headers, then all headers are processed correctly, but processing efficiency decreases
Solution Approach 1:
The system extracts identification information from the data packet to determine which specific headers require processing. By identifying only the necessary headers beforehand, the system avoids the inefficiency of processing all headers layer-by-layer, thereby improving processing efficiency while ensuring correct processing of the required headers through targeted parsing operations
Solution Approach 2:
The patent performs preliminary identification of the headers that need to be processed before actual parsing begins. By determining the specific header layers requiring modification in advance using identification information, the system prepares a targeted processing plan that ensures correct processing while avoiding unnecessary operations, thus improving overall processing efficiency

AI summary
This disclosure provides a data packet processing method and apparatus, and an electronic device, and relates to the field of communication technologies. The method includes: receiving a first data packet, wherein the first data packet comprises N layers of headers, and N is a positive integer; determining a first header, wherein the first header is a K-th layer header in the N layers of headers, K is a positive integer, and K < N; and parsing up to the first header when performing parsing processing on the headers of the first data packet.
