Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traditional serial packet processing is used, then processing is simple to implement, but processing speed decreases and processor resources are consumed by high network traffic volume
Solution Approach 1:
The patent segments packets into fixed-size blocks (e.g., 64-byte segments) and organizes them into vectors for parallel processing. Each packet is divided into multiple segments that can be processed simultaneously using SIMD instructions, transforming serial packet processing into parallel block processing to increase throughput and reduce processor resource consumption.
Solution Approach 2:
The patent merges multiple packet segments into vector structures that can be processed together using single SIMD instructions. By combining segments from multiple packets into unified data structures, the system performs batch operations that process many packets simultaneously, improving processing speed while reducing the overall computational burden on processor resources.
2Productivity
If packet processing operations are performed on high volume network traffic, then network communication is maintained, but computational burden increases and processing time increases
Solution Approach 1:
The patent implements continuous parallel processing by maintaining pipeline operations where packet segmentation, vector formation, SIMD processing, and result assembly occur simultaneously in overlapping stages. This continuous action ensures high network throughput is maintained without idle processing time, as each stage operates concurrently with others rather than sequentially.
Solution Approach 2:
The patent transforms traditional single-threaded packet processing into multi-dimensional parallel processing by organizing packets into vectors and using SIMD instructions that operate on multiple data elements simultaneously. This dimensional transformation from serial to parallel processing reduces processing time while maintaining or increasing network throughput through simultaneous operations on multiple packets.
3Speed
If processing resources are allocated to handle high speed network traffic, then network performance is improved, but application performance deteriorates due to resource consumption
Solution Approach 1:
The patent implements self-service by using hardware-accelerated SIMD instructions that are natively supported by modern processors. These instructions perform parallel packet processing operations efficiently using built-in processor capabilities rather than consuming general-purpose CPU cycles, allowing the system to maintain high network processing speed while minimizing the impact on application performance through dedicated processing pathways.
