Integrated Load Sharing Board for Reliable Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load sharing methods in communications systems face low data transmission reliability due to the separation of management control units and forwarding units, leading to complex networking and high hardware costs, as well as the need for multiple boards for distributed load sharing.
Innovation Solution
A method and apparatus where a management control unit and a forwarding unit share a board, with the management control unit determining the optimal forwarding unit for data transmission based on current load ratios and thresholds, allowing for dynamic adjustment and utilization of both built-in and external forwarding units to improve reliability and reduce complexity and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If management control unit and forwarding unit are physically separated, then distributed load sharing function is implemented, but data transmission reliability is low and device complexity is high
Solution Approach 1:
The patent combines the management control unit and forwarding unit onto the same board, creating an integrated architecture. This merging resolves the reliability issues caused by physical separation while maintaining distributed load sharing capabilities through the board's participation in the larger distributed system.
Solution Approach 2:
The board is designed to serve multiple functions: it acts as both a management control unit and a forwarding unit, and can participate in distributed load sharing across multiple boards. This multi-functionality allows the system to achieve distributed load sharing without requiring separate dedicated components for each function.
2Adaptability or versatility
If management control unit and forwarding unit are physically separated, then distributed load sharing function is implemented, but hardware cost is high
Solution Approach 1:
By merging the management control unit and forwarding unit onto the same board, the patent reduces the total number of separate hardware components required. This consolidation lowers hardware costs while maintaining the distributed load sharing function through coordination between multiple integrated boards.
Solution Approach 2:
The integrated board performs multiple functions (management control and data forwarding) that would traditionally require separate dedicated hardware. This multi-functionality reduces hardware requirements and manufacturing costs while preserving distributed load sharing capabilities.
3Productivity
If multiple boards are used for distributed load sharing, then load sharing capability is improved, but device complexity is high
Solution Approach 1:
The patent integrates management control and forwarding functions onto the same board, reducing the number of separate components that need to be coordinated. This integration simplifies the overall device complexity while maintaining distributed load sharing capability across multiple boards.
Solution Approach 2:
Each board is designed as a universal unit that can perform both management control and data forwarding functions. This standardization reduces device complexity by eliminating the need for specialized separate components, while still enabling distributed load sharing across the multi-board system.

AI summary
Embodiments of the present invention provide a load sharing method and apparatus, and a board. The method includes: receiving, by a built-in forwarding unit, to-be-transmitted data; obtaining, by a management control unit, current load ratios of forwarding units; and if it is determined that a current load ratio of any forwarding unit of the forwarding units is less than a preset load ratio threshold, determining that the forwarding unit is a unit for forwarding the to-be-transmitted data, where the built-in forwarding unit and the management control unit are located in a same board, and the forwarding units include the built-in forwarding unit and another forwarding unit outside the board. The present invention can solve a problem of low data transmission reliability in an existing load sharing method.
