IPFS Batch Image Distribution via Node Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional IPFS image distribution methods face challenges in rapid response times and transmission efficiency due to network congestion, uneven distribution of image blocks, and reliance on central repositories, leading to increased user waiting times and service latency in high-concurrent and fast-scaling scenarios.
Innovation Solution
A batch-type image distribution method using an IPFS system that calculates a caching ratio for each node, selects nodes with higher caching ratios as source nodes, constructs an IPFS network, and uses an optimization algorithm to prioritize image downloads, continuously updating the list of source and demand nodes to optimize bandwidth usage and reduce competition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple nodes download images from the central image repository in parallel, then the service scale can be expanded, but network resources of the image repository become congested, affecting download speed and service startup latency
Solution Approach 1:
The patent segments the image distribution task by dividing nodes into source nodes (that have images) and demand nodes (that need images). Instead of all nodes downloading from a central repository, the system segments the distribution function across multiple source nodes that can simultaneously serve multiple demand nodes, reducing central repository congestion while maintaining scalable service expansion
Solution Approach 2:
The patent introduces IPFS (InterPlanetary File System) as an intermediary distribution mechanism between source nodes and demand nodes. This intermediary system enables direct peer-to-peer image transfer, eliminating the need for all nodes to access the central repository simultaneously, thus resolving the congestion problem while supporting service scale expansion
2Speed
If traditional IPFS image distribution is used, then overall distribution speed improves, but all nodes complete image download and service startup at the same moment, increasing user waiting time
Solution Approach 1:
The patent applies preliminary action by having source nodes prepare and publish images to the IPFS network before demand nodes need them. Source nodes proactively share image data with the IPFS system in advance, allowing demand nodes to immediately access already-available images rather than waiting for simultaneous download completion, thus reducing user waiting time while maintaining fast distribution
Solution Approach 2:
The patent introduces dynamic batching that continuously updates the list of source and demand nodes based on real-time download progress and service startup status. This dynamic adjustment allows the system to optimize the distribution process adaptively, ensuring that nodes with faster download progress become source nodes earlier, thereby distributing the completion time more evenly and reducing maximum waiting time
3Adaptability or versatility
If IPFS DHT level routing is used to find source nodes, then image transmission can occur between nodes, but network topology becomes huge and complex, slowing down node discovery
Solution Approach 1:
The patent applies partial action by having nodes only perform DHT routing queries when necessary (when no direct peer connection exists or source nodes are not immediately available). Most of the time, nodes can directly access images through simplified peer-to-peer connections or cached references, avoiding the need for complex full DHT traversal and reducing overall network discovery time while maintaining the versatility of IPFS routing
4Productivity
If demand nodes download images from limited source nodes in the initial stage, then image distribution can begin, but competition among downloaders for network resources increases, affecting transmission quality
Solution Approach 1:
The patent implements feedback mechanisms where demand nodes continuously monitor download progress, network conditions, and source node availability. Based on this feedback, the system dynamically adjusts the list of active source nodes and demand nodes, redirecting downloads to less congested sources when detected, thereby maintaining transmission quality while enabling efficient initial distribution
Solution Approach 2:
The patent introduces dynamic reconfiguration of source and demand node lists based on real-time network conditions and download progress. As the initial distribution stage progresses and network resources become available, the system dynamically expands the number of active source nodes, reducing competition among downloaders and improving transmission quality while maintaining high distribution productivity

AI summary
The present application discloses a batch-type image distribution method based on an IPFS, which includes: obtaining a list of cluster nodes needed to download images; calculating a caching ratio of an image layer of images to be distributed of each node, comparing the caching ratio of each node with a threshold of a preset node, and obtaining a complete image from an image repository; adding the node with the complete image to a list of source nodes, and adding remaining nodes needed to download images to a list of demand nodes, and constructing an IPFS network, and exporting and sharing the image; calculating target demand nodes using an optimization algorithm, and inputting the target demand nodes into the IPFS network for image download, and importing the downloaded image into a container and starting the container.
