Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If virtual network card operations are implemented using software, then the virtual machine can provide network forwarding functionality, but the CPU and memory resources are significantly occupied, leading to poor performance
Solution Approach 1:
The patent replaces the software-based virtual network card implementation with a hardware-based programmable network card device. The virtual network card functions are offloaded to a dedicated hardware device with programmable logic, substituting the software processing mechanism with a hardware processing mechanism. This hardware device includes a network card acceleration module that can be programmed to perform packet forwarding, filtering, and other network operations directly in hardware, eliminating the need for CPU and memory involvement in virtual network card operations.
2Speed
If hardware offloading is implemented to improve data transmission speed, then network forwarding performance is enhanced, but the device complexity increases due to the need for programmable hardware and service interface components
Solution Approach 1:
The patent implements a universal programmable network card device that can serve multiple virtual machines and perform multiple network functions through a single hardware platform. The device includes a programmable logic unit that can be configured to handle different network protocols, forwarding rules, and processing requirements. This multi-functional design eliminates the need for separate dedicated hardware for each virtual machine or function, reducing overall system complexity while maintaining high performance.
Solution Approach 2:
The patent introduces a service interface component as an intermediary layer between the virtual machine software and the programmable hardware device. This intermediary handles the complexity of hardware configuration, programming, and control, presenting a simplified interface to the virtual machine while managing the complex hardware operations. The service interface abstracts the hardware complexity, allowing virtual machines to use the hardware offloading capability without directly dealing with the underlying hardware complexity.
