Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communications networks with limited resources, such as in-vehicle networks, existing technologies fail to provide reduced communications complexity and efficient power and bandwidth utilization, leading to suboptimal network performance and increased power consumption.
Innovation Solution
A method and device for generating packets with a header that includes packet type information indicating network connections, allowing for point-to-point or point-to-multipoint communications, and optionally including address information, protocol type, priority, and network cluster information, which are transmitted through the network, optimizing packet structure and transmission efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If typical network technology is used, then communications can be established, but communications complexity increases and power/bandwidth utilization efficiency decreases
Solution Approach 1:
The patent segments the communications network into multiple network clusters, where each cluster operates with its own simplified routing rules. This segmentation allows devices to communicate efficiently within clusters without requiring complex global routing decisions, thereby reducing overall communications complexity while improving power and bandwidth utilization efficiency.
Solution Approach 2:
The patent implements local quality by allowing different network clusters to have different communication characteristics and routing policies tailored to their specific requirements. This enables optimized power and bandwidth utilization for each cluster's local conditions while maintaining overall network functionality, reducing the need for complex centralized control.
2Adaptability or versatility
If comprehensive address information is included in packet headers, then routing flexibility is improved, but packet overhead increases
Solution Approach 1:
The patent extracts the routing information requirement from the packet header by utilizing the packet type field to indicate the network cluster destination. This extraction eliminates the need for comprehensive address information in headers, significantly reducing packet overhead while maintaining routing flexibility through the simplified packet type-based routing mechanism.
