Image File Block Distribution Across Edge Cloud Nodes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The time overheads and low download speed of image files from a central cloud node to edge cloud nodes in cloud computing systems are significant due to shared bandwidth limitations and varying network conditions.
Innovation Solution
Distribute image file data blocks across multiple edge cloud nodes, enabling local access and reducing reliance on central cloud downloads by utilizing edge cloud node bandwidth and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If image files are stored and downloaded from a central cloud node, then centralized management is achieved, but download speed and time overhead deteriorate due to shared bandwidth limitations
Solution Approach 1:
The patent segments the image file into multiple data blocks and distributes them across multiple edge cloud nodes instead of storing the complete file at a single central node. This segmentation enables parallel access and retrieval operations, significantly improving download speed while maintaining manageable distribution through centralized coordination of the segmentation scheme
Solution Approach 2:
The patent transitions from a single-dimension centralized storage model to a multi-dimensional distributed storage architecture where data blocks are dispersed across multiple edge nodes. This dimensional change from centralized to distributed topology enables simultaneous access from multiple points, resolving the bandwidth bottleneck while preserving management capabilities through hierarchical control
2Reliability
If image files are downloaded from central cloud node, then centralized control is maintained, but time overhead increases due to network distance and shared bandwidth
Solution Approach 1:
The patent performs preliminary distribution of image file data blocks to multiple edge cloud nodes before they are needed. This advance distribution reduces the time overhead during actual retrieval operations, as data is already positioned at multiple access points. Centralized control is maintained through coordination of the preliminary distribution process and metadata management
Solution Approach 2:
The patent introduces edge cloud nodes as intermediaries between the central cloud node and end users. These intermediary nodes store data blocks locally and handle retrieval requests, reducing the time overhead associated with direct central-node access. The intermediary layer maintains centralized control by reporting to and receiving instructions from the central node while independently serving local requests

AI summary
An image file management method includes receiving a write instruction used to instruct to write a first image file; determining, based on the write instruction, at least one first edge cloud node from a plurality of edge cloud nodes included in an image file management system; and writing a plurality of data blocks included in the first image file into the at least one first edge cloud node, so that each first edge cloud node stores a part or all of the plurality of data blocks included in the first image file.
