Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed hash algorithm is used for load balancing, then the load balancing process is simple, but network polarization occurs and traffic is not evenly distributed across links
Solution Approach 1:
The patent applies dynamics by making the hash algorithm information changeable rather than fixed. The load balancing device dynamically determines hash algorithm information for the second communication device based on the first communication device's hash algorithm information and port quantity, allowing the system to adapt to different network conditions and device configurations, thereby preventing network polarization while maintaining operational simplicity.
Solution Approach 2:
The patent changes the parameters of the hash algorithm by determining hash algorithm information (including hash algorithm type and port quantity) based on the first communication device's parameters. This parameter adaptation allows the load balancing to achieve uniform traffic distribution across different network scenarios without complicating the overall process.
2Device complexity
If hash algorithm information is determined without considering port quantity, then the determination process is simple, but packet distribution across ports is ineffective
Solution Approach 1:
The patent applies preliminary action by having the first communication device send its hash algorithm information and port quantity to the load balancing device in advance. This allows the load balancing device to determine appropriate hash algorithm information for the second communication device before actual packet forwarding occurs, ensuring effective packet distribution without adding complex real-time calculation requirements.
3Ease of manufacture
If the same hash algorithm information is used by both communication devices, then configuration is simple, but network polarization cannot be alleviated
Solution Approach 1:
The patent applies local quality by making the hash algorithm information specific to each communication device's characteristics. The load balancing device determines hash algorithm information for the second communication device based on the first device's information and port quantity, creating device-specific configurations that prevent network polarization while maintaining overall system simplicity through automated determination.
