Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Wake-on-LAN (WOL) technologies face challenges in optimizing hardware performance of computer hosts due to unsupported network chip protocols, leading to suboptimal utilization of network chips, especially in cloud computing environments.
Innovation Solution
A computer system and remote control method that optimizes network chip performance by identifying the unique ID code of the network communication unit, searching an ID table to determine the most adaptable packet format, and setting up an agreement packet to notify the remote device, ensuring secure and efficient wake-up packets are used for remote control operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system uses a universal WOL protocol to ensure broad compatibility, then more network chips can be supported, but the hardware performance of specific network chips cannot be optimized
Solution Approach 1:
The system dynamically selects the appropriate WOL protocol based on the detected network chip type. During initialization, the system identifies the network chip model and automatically chooses the most suitable protocol from multiple supported protocols (e.g., Magic Packet, Wake-on-WLAN, Wake-on-LAN), thereby optimizing performance for each specific hardware configuration while maintaining broad compatibility across different chip types
Solution Approach 2:
The system changes protocol parameters based on network chip characteristics. By detecting the network chip's ID code and consulting a protocol support table, the system adjusts packet format, transmission method, and other protocol parameters to match the optimal configuration for each specific network chip model, maximizing hardware performance while ensuring compatibility
2Productivity
If the system implements detailed network chip detection and protocol selection, then network chip performance can be optimized, but the system complexity increases
Solution Approach 1:
The system performs self-detection of network chip characteristics during initialization and automatically selects the optimal protocol without requiring manual configuration or complex external intervention. The automatic detection mechanism queries the network chip's ID code and autonomously determines the best protocol based on pre-stored compatibility information, simplifying the user experience while achieving performance optimization
Solution Approach 2:
The system pre-stores protocol support information in a lookup table that maps network chip ID codes to supported protocols. This preliminary preparation allows the system to quickly determine the optimal protocol through simple table lookup rather than complex real-time analysis, reducing computational overhead and system complexity while maintaining performance optimization capabilities
3Ease of manufacture
If the system uses existing WOL protocols, then implementation is straightforward, but network chip supportability is limited
Solution Approach 1:
The system implements multiple WOL protocols (Magic Packet, Wake-on-WLAN, Wake-on-LAN, and others) within a single unified framework. By maintaining support for various protocol types and automatically selecting the appropriate one based on network chip characteristics, the system achieves broad hardware compatibility while keeping the implementation approach consistent and manageable through a single detection and selection mechanism

AI summary
A computer system and a remote control method for a computer device are provided. The computer system includes a computer device and a remote device. The computer device includes a network communication unit and an ID table. Before the computer device enters into a power-saving state, the computer device reads an ID code of the network communication unit and searches the ID table according to the ID code to obtain a particular packet format type. The computer device sends an agreement packet including a message of the particular packet format type to notify the remote device. The computer device receives a response packet from the remote device for setting a packet receiving procedure and enters into the power-saving state. When the computer device receives a wake-up packet compliant with the packet receiving procedure from the remote device, the computer device returns to a normal operation state.
