File Upload Address Management for Resuming Interrupted Transfers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies fail to restart an upload operation if the upload destination is changed during the process and then reconnected, lacking the ability to store information about interrupted upload operations or resume the upload based on that information.
Innovation Solution
A communication apparatus and method that manage and utilize transmission destination addresses for multiple connection destinations, enabling the restart of upload operations from the state of interruption by managing and transmitting files using these addresses, even if the connection destination changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the upload destination is changed during the upload operation, then the system can adapt to new connection requirements, but the ability to store and resume interrupted upload information is lost
Solution Approach 1:
The patent segments the upload management by creating separate management files for each connection destination. When a connection destination changes, the system switches to the corresponding management file, allowing independent tracking of upload states for each destination. This segmentation enables both adaptability to destination changes and reliable resumption by preserving upload information in destination-specific files.
Solution Approach 2:
The patent performs preliminary actions by creating and maintaining management files that store upload information before interruptions occur. These management files are prepared in advance to record file names, upload progress, and other necessary information, enabling the system to quickly resume uploads without losing track of the interrupted operation when connection destinations change.
2Reliability
If the system stores detailed upload information for each connection destination, then the ability to resume uploads is improved, but the device complexity increases
Solution Approach 1:
The patent uses copying by creating management files that contain copied or replicated upload information for each connection destination. Instead of maintaining complex interlinked data structures, the system copies essential upload metadata into separate management files, simplifying the overall system architecture while enabling reliable upload resumption across multiple destinations.
3Productivity
If the system manages transmission destination addresses for multiple connection destinations, then the productivity of file transfer is improved, but the difficulty of detecting and measuring upload state increases
Solution Approach 1:
The patent introduces management files as intermediary components between the upload operation and multiple connection destinations. These management files serve as mediators that standardize the representation of upload state information, making it easier to detect and measure upload progress across different destinations without increasing complexity in the core transfer mechanism.

AI summary
A communication apparatus for communicating with an external apparatus having a plurality of connection destinations includes an acquisition unit configured to acquire, from the external apparatus, a transmission destination address of a file, a management unit configured to manage the transmission destination address for each connection destination of the plurality of connection destinations, and a transmission unit configured to transmit the file to the external apparatus by using the transmission destination address.
