Path-Aware Packet Headers for Multi-Type RTN Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing real-time network (RTN) data transmission technologies are limited to audio and video data and do not support private protocols or non-audio and video data types, lacking flexibility and adaptability.
Innovation Solution
A data transmission method that determines a first transmission path between nodes, generates a packet with a protocol header indicating this path, and sends the packet, allowing intermediate nodes to acquire path information without decapsulating the entire packet, thereby supporting various data types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing RTN data transmission technologies are used, then audio and video data can be transmitted, but the system does not support private protocols or non-audio and video data types
Solution Approach 1:
The patent applies universality by designing a packet structure with a generic protocol header that can accommodate multiple data types including audio, video, and private protocol data. The protocol header contains field information that identifies the data type, allowing the same transmission mechanism to handle diverse data types without requiring separate specialized systems for each type.
Solution Approach 2:
The patent uses parameter changes by modifying the protocol header structure to include data type identification fields. By changing the parameters within the protocol header (specifically the field information that indicates data type), the system can dynamically adapt to handle different data types through the same transmission framework, thereby improving versatility without increasing overall system complexity.
2Reliability
If intermediate nodes decapsulate entire packets to acquire path information, then path routing is accurate, but transmission efficiency decreases
Solution Approach 1:
The patent applies the extraction principle by separating the path information from the entire packet structure. Instead of requiring intermediate nodes to decapsulate complete packets to access routing information, the invention extracts and places path information into a dedicated protocol header. This allows intermediate nodes to acquire path information by reading only the header portion without processing the entire packet payload, thereby maintaining routing accuracy while improving transmission efficiency.
Solution Approach 2:
The patent applies segmentation by dividing the packet into distinct components: a protocol header containing path information and the actual data payload. This segmentation allows intermediate nodes to process only the relevant header portion for routing decisions without unnecessarily handling the entire packet, thus reducing processing overhead and improving transmission efficiency while maintaining accurate path routing.
3Productivity
If a protocol header indicating transmission path is added to packets, then intermediate nodes can acquire path information efficiently, but packet size increases
Solution Approach 1:
The patent applies partial action by including only the essential path information in the protocol header rather than redundant or excessive data. The protocol header contains field information that indicates data type and path routing details, which is the minimum necessary information for intermediate nodes to perform efficient routing without requiring additional overhead. This partial inclusion of information achieves the goal of efficient path acquisition while minimizing the increase in packet size.
