Container File Transfer via Selective Component Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transferring large files over networks is time-consuming and power-intensive, especially for mobile devices, and increases security and data corruption risks due to bandwidth restrictions and the need to transmit duplicate data.
Innovation Solution
A method and system that minimizes data transfer by transmitting metadata first, allowing the server to determine which components of a container file are needed, and only sending those components, using techniques like caching and hash values to identify duplicate data, thereby reducing the amount of data transmitted and cached.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire container file is transmitted over the network, then the server receives complete data, but transmission time and power consumption increase significantly
Solution Approach 1:
The container file is divided into multiple component files, and the system transmits only the necessary components rather than the entire file. This segmentation allows selective transmission of data based on what the server actually needs, reducing overall transmission time while maintaining data completeness for required elements.
Solution Approach 2:
The system extracts and transmits only the specific component files that the server needs from the container file, rather than transmitting the complete container. This extraction approach eliminates unnecessary data transmission, directly reducing transmission time while ensuring the server receives all required components.
2Reliability
If the entire container file is transmitted over the network, then all data is available at the server, but power consumption increases significantly
Solution Approach 1:
The container file structure enables segmentation of data into discrete components, allowing the system to transmit only the necessary subset. This reduces the total data volume transmitted over the network, directly lowering power consumption while ensuring all required components are available at the server.
Solution Approach 2:
The system performs partial transmission by sending only the specific components needed by the server rather than the complete container file. This partial action approach reduces power consumption by minimizing network transmission activity while still achieving the goal of making necessary data available at the server.
3Reliability
If duplicate data is transmitted over the network, then all required data is ensured to be sent, but network bandwidth is wasted and transmission efficiency decreases
Solution Approach 1:
The container file structure segments data into identifiable components with unique characteristics. This segmentation enables the system to recognize and eliminate duplicate components before transmission, ensuring each unique component is sent only once. This maintains data delivery assurance while significantly improving transmission efficiency by eliminating redundant data transfer.
Solution Approach 2:
The system uses hash values as a parameter to identify and compare component files. By changing the representation of data from raw content to hash-based identifiers, the system can efficiently detect duplicates and avoid transmitting redundant components, thereby improving transmission efficiency while maintaining complete data delivery.
4Reliability
If large files are transmitted over the network, then complete data is transferred, but security risks and data corruption risks increase
Solution Approach 1:
The container file is segmented into smaller component files for transmission. This segmentation reduces the size of individual data transfers, thereby reducing the attack surface and risk of data corruption during transmission. Each smaller component can be independently verified and retransmitted if needed, improving security and reliability.
Solution Approach 2:
The system transmits only the partial set of components that the server actually needs rather than the complete container file. This partial transmission approach reduces the total data exposure to security risks and data corruption, while still achieving complete delivery of necessary data through selective component transfer.
