Link Aggregation Interface Grouping for Wireless Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, existing technologies face challenges in efficiently selecting access points (APs) capable of link aggregation, which affects the throughput and reliability of wireless networks, particularly in environments with multiple AP interfaces and varying link conditions.
Innovation Solution
A processing system is configured to identify AP interfaces supporting link aggregation, group them, select the optimal group for communication, and initialize link aggregation by sending information to the selected interfaces, allowing for improved channel selection and aggregation techniques such as flow level, packet level, and TDLS-based aggregation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple AP interfaces are used for link aggregation, then aggregated throughput is improved, but device complexity increases
Solution Approach 1:
The patent segments the AP interfaces into distinct groups based on their aggregation capabilities. Each interface is evaluated and categorized independently, allowing the system to manage multiple interfaces through structured segmentation rather than treating them as a monolithic complex system. This segmentation approach enables selective activation of aggregation-capable interfaces.
Solution Approach 2:
The patent implements dynamic management of link aggregation by continuously monitoring link conditions and adapting the aggregation configuration accordingly. The system can dynamically add or remove interfaces from aggregation groups based on real-time performance metrics, making the system adaptable rather than static, thereby managing complexity through flexibility.
2Reliability
If link aggregation is implemented, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent implements self-service mechanisms where the system automatically identifies which interfaces support link aggregation, groups them appropriately, and manages the aggregation configuration without requiring manual intervention. The system autonomously monitors link conditions and adjusts aggregation settings, eliminating the operational burden from users while maintaining high reliability through consistent automated management.
Solution Approach 2:
The patent changes operational parameters by automatically adjusting aggregation configurations based on detected interface capabilities and link conditions. Instead of requiring manual parameter setting, the system dynamically modifies aggregation parameters such as which interfaces are grouped together, thereby maintaining reliability while simplifying operation through automated parameter management.
3Productivity
If optimal group selection is performed, then aggregated throughput is improved, but loss of time increases
Solution Approach 1:
The patent performs preliminary actions by pre-identifying and grouping interfaces that support link aggregation before actual data transmission begins. The system proactively evaluates interface capabilities and establishes aggregation groups in advance, so that when data transmission is needed, the optimal configuration is already in place. This preliminary setup reduces the time penalty associated with dynamic optimization during operation.
