Multi-Network Data Transmission with Order-Based Loss Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-network environments, existing methods for transmitting or receiving large-capacity data often lead to uneven load distribution across networks, causing service disruptions due to inadequate handling of non-received partial data during simultaneous data transmission across multiple networks.
Innovation Solution
A system comprising a receiving device with a communication unit, information confirming unit, and control unit that receives and confirms transmission order information and network transmission order information for partial data across multiple networks, allowing for prompt determination of lost data and efficient retransmission, while a transmitting device divides data into partial units and assigns transmission orders to manage network usage effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If data is transmitted through one selected network from multiple networks, then the transmission method is simple, but the load factor of the selected network is abruptly increased causing service disruption
Solution Approach 1:
The transmitting device divides one piece of data into several pieces of partial data and simultaneously transmits them through two or more networks. The receiving device receives and reassembles the partial data to reconstruct the original data, thereby distributing the load across multiple networks and preventing service disruption.
2Reliability
If simultaneous data transmission through multiple networks is implemented, then data service smoothness is improved, but the complexity of determining lost data increases
Solution Approach 1:
The transmitting device inserts transmission order information indicating the transmission order assigned to each partial data before transmitting through multiple networks. The receiving device uses this pre-assigned order information to systematically determine which partial data are non-received and lost, simplifying the complexity of loss detection.
Solution Approach 2:
The receiving device generates a reception report based on transmission order information and network transmission order information to inform the transmitting device about received and lost partial data. This feedback mechanism enables the transmitting device to retransmit only the lost partial data, optimizing the simultaneous transmission process.
3Measurement precision
If transmission order information is inserted into each partial data, then lost data determination accuracy is improved, but the data processing overhead increases
Solution Approach 1:
Different types of transmission order information are applied to different partial data based on their transmission paths. Transmission order information is inserted into partial data transmitted through one network, while network transmission order information is inserted into partial data transmitted through another network, optimizing the information overhead for each transmission path.

AI summary
A receiving device includes: a communication unit to receive a plurality of partial data divided from data to be transmitted through two or more connection networks; an information confirming unit to confirm (i) transmission order information and (ii) network transmission order information indicating related to a transmission order assigned to of the specific partial data among the plurality of partial data to be transmitted through a the specific connection network designated among the two or more connection networks; and the control unit to determine whether non-received partial data are lost based on at least one of the transmission order information and the network transmission order information.
