Burst-Length Adjustment for Continuous Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transfer devices experience interruptions and delays when a part of the transfer target data is lost during division and transfer, leading to potential loss of important information.
Innovation Solution
A data transfer device that includes a storage device and a control device to manage data transfer by adjusting the burst length based on the number of untransmitted data units, ensuring continuous transfer even if some data units are lost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is divided into multiple pieces and transferred in a burst manner to enhance transfer speed, then productivity is improved, but reliability deteriorates because data transfer is interrupted when a part of the transfer target data is lost
Solution Approach 1:
The control device monitors the storage state of the storage device and detects when data is lost during transfer. Based on this feedback information, the control device dynamically adjusts the burst length to ensure that the data length to be transferred matches the actual number of untransferred data units, thereby maintaining transfer continuity and reliability while preserving high transfer speed
Solution Approach 2:
The burst length is made dynamic rather than fixed. The control device adjusts the burst length in real-time based on the actual storage state and data loss detection, allowing the system to adapt to changing conditions and maintain both high productivity and reliability
2Productivity
If data is divided into multiple pieces for burst transfer, then transfer efficiency is improved, but loss of information increases when data loss occurs during transfer
Solution Approach 1:
The control device continuously monitors whether data has been successfully transferred by checking the storage state of the storage device. When data loss is detected, the feedback mechanism triggers an adjustment of the burst length to match the actual number of untransferred data units, preventing information loss while maintaining high transfer efficiency
Solution Approach 2:
The burst length parameter is dynamically changed based on the actual transfer state. When data loss occurs, the control device changes the burst length parameter to ensure that the data length to be transferred coincides with the total of data lengths to be transferred, thereby preventing information loss while preserving transfer efficiency

AI summary
A data transfer device that divides and transfers the transfer target data in a burst manner from a transmission-side device to a reception-side device includes a storage device and a control device that controls the storage device to store one piece of the input transfer target data, controls the storage device so that data transfer is performed at a set burst length as a data length of divided data when the one piece of the data is divided by a division number until a last part of the data is sensed, and when the last part of the data is sensed, controls the storage device to adjust the burst length so that a data length of the data coincides with a total of data lengths of data to be transferred, and to transfer the data at the adjusted burst length.
