Network Backup Device Switching Module Aggregation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network backup systems are complex and costly due to the need for dualization of terminal switches and backup network switches, which requires high costs and non-standardized terminal devices, leading to interruptions in network communication when faults occur.
Innovation Solution
A network backup device with a switching module that aggregates data from faulty ports and transfers it to a backup network switch, simplifying the backup process by directly connecting terminal devices to the backup switch in case of faults, and reducing the size and complexity of backup network equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terminal switches are dualized to maintain communication without interruption, then network reliability is improved, but device complexity and production cost increase
Solution Approach 1:
The patent merges multiple backup configurations into a single unified backup network switch that can serve multiple primary switches. Instead of having separate backup switches for each primary switch, the invention consolidates the backup function into one device that dynamically adapts to replace any failed primary switch, thereby reducing overall system complexity while maintaining reliability.
Solution Approach 2:
The backup network switch is designed with universal functionality to perform multiple backup roles simultaneously. It can back up different primary switches with different port configurations by dynamically reconfiguring its own ports and connections, eliminating the need for dedicated backup switches for each primary switch and reducing device complexity.
2Reliability
If backup network switch has the same size and constitution as primary network switches, then reliability is improved through one-to-one replacement, but device complexity and production cost increase
Solution Approach 1:
The backup network switch employs dynamic reconfiguration capabilities where port roles and connections can be changed in real-time based on which primary switch has failed. Instead of being statically configured for a specific primary switch, the backup switch dynamically adapts its configuration to match the needs of the failed primary switch, maintaining reliability while reducing complexity.
Solution Approach 2:
The invention utilizes parameter changes in the backup switch's operational state, allowing it to change its functional characteristics (such as port assignments, VLAN configurations, and routing parameters) depending on which primary switch requires backup. This flexibility enables a single backup switch to replace multiple primary switches with different configurations.
3Adaptability or versatility
If network backup device has ports varying according to the number of network switches, then adaptability is improved, but production cost increases due to wasted ports
Solution Approach 1:
The network backup device is designed with universal port functionality where each port can serve multiple purposes depending on the backup requirements. Instead of having dedicated ports for each primary switch, the ports are multi-functional and can be dynamically assigned to different primary switches based on current backup needs, maintaining adaptability while reducing the total number of ports required and lowering production costs.
