Link Aggregation Module for Simultaneous Wired Wireless Packet Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information handling systems primarily rely on single network interfaces for communication, which limits bandwidth and reliability, especially in environments with wireless congestion and Specific Absorption Rate (SAR) restrictions, making indirect network interfaces unreliable for applications requiring consistent service.
Innovation Solution
A client information handling system uses link aggregation to communicate through multiple network interfaces by manipulating network packets at the network layer, managing network packet assignment and optimizing communication medium states to ensure efficient distribution across available interfaces, while tracking SAR limits to maintain wireless transmit power and quality of service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple network interfaces are used simultaneously, then bandwidth is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple network interfaces (wired Ethernet and wireless WLAN) into a unified communication system where a single application can simultaneously utilize both interfaces. The system merges the capabilities of separate network interfaces to provide aggregated bandwidth while presenting a unified interface to the application, thereby increasing productivity without proportionally increasing complexity from the application's perspective.
Solution Approach 2:
The patent creates a multi-functional network communication system that can operate through multiple types of interfaces (wired and wireless) simultaneously. The system is designed to handle various network protocols and interface types through a universal framework, allowing a single application to access multiple network mediums without requiring separate applications for each interface type.
2Productivity
If indirect network interfaces (peer-to-peer, mesh) are used, then bandwidth is improved, but reliability deteriorates
Solution Approach 1:
The patent implements dynamic interface selection and management where the system can adaptively choose between direct access points and indirect peer-to-peer or mesh interfaces based on current network conditions. When direct access is unavailable or suboptimal, the system dynamically establishes indirect paths through other clients, allowing bandwidth optimization while maintaining reliability through adaptive routing decisions.
Solution Approach 2:
The patent uses intermediary clients in peer-to-peer and mesh network configurations to facilitate communication when direct access points are unavailable. These intermediary clients act as mediators that relay data between the source and destination, enabling indirect network access that can provide substantial bandwidth while managing the inherent reliability challenges of indirect paths through multiple hops.
3Adaptability or versatility
If wireless network interfaces are used, then adaptability is improved, but SAR restrictions worsen performance
Solution Approach 1:
The patent dynamically changes transmission parameters including power levels, frequency selection, and interface selection based on SAR constraints and network conditions. The system monitors SAR limits and adjusts wireless transmission parameters in real-time, switching between wired and wireless interfaces, and modifying wireless power output to remain within SAR limits while maximizing data transfer rates within those constraints.
