Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If packet scheduling is optimized based on upper-layer protocol entity indications, then data transmission efficiency is improved, but device complexity increases
Solution Approach 1:
The patent segments the packet processing function into two independent parts: (1) upper-layer protocol entity generates indication information about packet scheduling priorities, and (2) lower-layer protocol entity executes scheduling based on these indications. This segmentation allows each layer to operate independently, improving transmission efficiency without significantly increasing overall system complexity.
Solution Approach 2:
The upper-layer protocol entity performs preliminary analysis and generates indication information about packet priorities before the lower-layer entity performs actual scheduling. This preliminary action enables the lower layer to make faster scheduling decisions without performing complex analysis itself, thus improving efficiency while keeping device complexity manageable.
2Loss of energy
If packet processing is optimized with indication information from upper-layer protocol entities, then power consumption is reduced, but device complexity increases
Solution Approach 1:
The patent extracts the complex packet analysis function from the lower-layer protocol entity and relocates it to the upper-layer protocol entity. The lower layer only needs to execute simple scheduling decisions based on indication information, which significantly reduces its processing complexity and power consumption while maintaining optimized packet handling.
Solution Approach 2:
The upper-layer protocol entity serves itself by generating the indication information it needs for packet scheduling, eliminating the need for the lower layer to perform complex analysis. This self-service approach reduces inter-layer communication overhead and simplifies the lower layer's processing requirements.

AI summary
A packet processing method and apparatus. The packet processing method includes: in a case that a first condition is met, a first protocol entity prioritizes transmission of a target packet or prioritizes discarding of the target packet, where the first condition includes at least one of the following: the first protocol entity receives first indication information from a second protocol entity; and the first protocol entity does not receive second indication information from the second protocol entity; where the target packet is a packet corresponding to the first indication information or the second indication information, and the second protocol entity is an upper-layer protocol entity of the first protocol entity. In the embodiments of this application, data transmission efficiency can be improved.
