Adaptive CPU Scheduling for Virtual Packet Processing Overhead
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In virtual computing environments, conventional data packet processing methods involving continuous polling and interrupt-driven processing lead to inefficient use of processor resources due to context switching overhead and wasted processing cycles, especially when handling multiple virtualized software sets.
Innovation Solution
Implement a method that uses a sleep timer to pause virtual processes when no data packets are received, adjusting processing times based on packet receipt rates and historical timing to optimize resource allocation among multiple virtual processes.

Engineering Contradiction Analysis
1Speed
If continuous polling is used to check for data packets, then packet processing responsiveness is improved, but processor efficiency deteriorates due to wasted processing cycles when no packets are received
Solution Approach 1:
The patent implements periodic action by using interrupt-driven processing where the processor transitions from continuous polling to event-triggered processing. The processor sleeps and wakes up only when a data packet arrives, creating a periodic action pattern that eliminates wasted processing cycles while maintaining responsiveness to packet arrivals.
Solution Approach 2:
The system applies self-service by allowing the hardware interrupt mechanism to automatically wake the processor when a data packet arrives. Instead of the processor continuously checking for packets, the system self-manages the wake-up process through hardware interrupts, reducing processor overhead while maintaining packet processing responsiveness.
2Productivity
If interrupt-driven processing is used for data packets, then processor efficiency is improved by reducing polling overhead, but processing speed deteriorates due to context switching overhead
Solution Approach 1:
The patent applies preliminary action by pre-configuring interrupt handlers and context switching mechanisms before packets arrive. The system prepares the processing environment in advance so that when an interrupt occurs, the context switching overhead is minimized. This allows interrupt-driven processing to maintain high processor efficiency while reducing the speed penalty of context switching.
Solution Approach 2:
The system uses parameter changes by dynamically adjusting interrupt priorities, threshold values, and processing parameters based on packet arrival patterns. This allows the system to optimize the balance between processor efficiency and processing speed by changing operational parameters rather than being fixed in one processing mode.
3Productivity
If multiple virtualized software sets are executed on shared hardware, then hardware resource utilization is improved, but processing overhead increases due to resource contention and context switching
Solution Approach 1:
The patent implements segmentation by dividing the shared hardware resources into isolated virtualization contexts, each with its own interrupt handling and processing parameters. This segmentation allows multiple virtualized software sets to run concurrently on shared hardware while reducing processing overhead through resource isolation and targeted context switching only when necessary.
Solution Approach 2:
The system applies universality by creating a multi-functional processing framework that can handle different types of packets and virtualized software sets through a unified interrupt-driven architecture. This universal approach improves hardware resource utilization while managing complexity through standardized processing paths that reduce overall overhead.
