Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current load balancing algorithms in enterprise edge routers apply a single algorithm to all applications, which is inefficient as different applications require different load balancing strategies for optimal efficiency and correctness.
Innovation Solution
Dynamically select a load balancing algorithm based on application or policy attributes, using application-based or policy-based schemes to match the appropriate algorithm with the type of application, such as source IP address, destination IP address, or protocol type, to optimize traffic distribution.

Engineering Contradiction Analysis
1Productivity
If a single load balancing algorithm is applied to all applications, then the device complexity is reduced and ease of operation is improved, but network efficiency and bandwidth utilization deteriorate
Solution Approach 1:
The patent segments the load balancing configuration by creating separate load balancing groups (LBGs) and load balancing policies (LBPs) that can be independently configured for different applications. This allows each application to have its own optimized load balancing algorithm while maintaining manageable complexity through modular organization.
Solution Approach 2:
The patent implements dynamic load balancing algorithm selection by allowing the system to automatically choose appropriate load balancing algorithms based on application characteristics and current network conditions. This dynamic approach optimizes network efficiency without requiring manual configuration of multiple algorithms.
2Adaptability or versatility
If a single load balancing algorithm is applied to all applications, then the ease of operation is improved, but the adaptability to different application requirements deteriorates
Solution Approach 1:
The patent implements preliminary action by providing pre-configured load balancing policies and groups that can be automatically applied to applications based on their characteristics. This allows the system to adapt to different application requirements without requiring manual configuration, thereby maintaining ease of operation while improving adaptability.
Solution Approach 2:
The patent enables self-service by allowing the load balancing system to automatically select and apply appropriate load balancing algorithms based on application attributes and policy rules. This automation provides application-specific adaptability without increasing operational complexity for users.
3Reliability
If application-specific load balancing algorithms are implemented, then network efficiency and bandwidth utilization are improved, but the device complexity increases
Solution Approach 1:
The patent segments the load balancing system into distinct components including load balancing groups, load balancing policies, and application-specific algorithm selections. This segmentation ensures reliable packet delivery for each application type while managing system complexity through modular, organized configuration structures.
