Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing link aggregation techniques, such as IEEE 802.1AX, fail to effectively support wireless links due to inconsistent and dynamic radio bandwidth changes, leading to inefficient load balancing and redundancy issues.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional hashing algorithms (IEEE 802.1AX) are used for link aggregation, then load balancing can be achieved across multiple physical links, but the system fails to adapt to dynamic radio bandwidth changes in wireless environments
Solution Approach 1:
The patent implements dynamic link aggregation by continuously monitoring the capacity of each wireless link and adjusting the distribution of virtual containers in real-time. Unlike static hashing algorithms, this system adapts to changing radio conditions by reallocating traffic based on current link availability and capacity, ensuring optimal utilization of wireless resources.
Solution Approach 2:
The system changes the parameter of traffic distribution by using capacity-based allocation instead of fixed hashing. The aggregation engine dynamically adjusts the weight or proportion of traffic assigned to each link based on measured capacity metrics, allowing the system to respond to bandwidth fluctuations and maintain effective link aggregation in wireless environments.
2Reliability
If multiple wireless links are aggregated to increase bandwidth and redundancy, then carrier-class availability is achieved, but traditional link aggregation techniques cannot effectively manage inconsistent radio bandwidth
Solution Approach 1:
The patent segments customer traffic into multiple virtual containers that can be independently routed over different wireless links. This segmentation allows the system to distribute traffic across multiple aggregated links while managing inconsistent radio bandwidth by assigning virtual containers to links based on current capacity conditions, thereby maintaining reliability despite variable link quality.
Solution Approach 2:
The aggregation engine implements feedback mechanisms by continuously monitoring the capacity and status of each wireless link. Based on this feedback, the system dynamically adjusts the distribution of virtual containers to maintain carrier-class availability, ensuring that traffic is always routed over available links with sufficient capacity to meet service level requirements.
3Device complexity
If static link aggregation is implemented, then simple traffic distribution is achieved, but the system cannot perform adaptive capacity adjustments for wireless links
Solution Approach 1:
The system performs preliminary actions by pre-segmenting customer traffic into virtual containers that are ready for dynamic allocation. This preparation allows the aggregation engine to quickly adapt to changing wireless conditions without complex real-time processing, maintaining relative simplicity while enabling adaptive capacity adjustments through pre-organized traffic structures.
