Solution Overview

Problem

Conventional peer-to-peer data download methods are not suitable for wired and wireless integrated networks due to limited bandwidth and storage capabilities of wireless nodes, making it difficult to apply the existing wired network-based peer-to-peer data download methods in such environments.

Innovation Solution

A method that downloads data only through wired nodes in the download path and selectively caches data in wired nodes, using a holder node to determine whether the next node is wired or wireless and transmitting information or data accordingly, thereby bypassing wireless nodes and optimizing data transfer in a wired and wireless integrated network.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If data is downloaded through all nodes in the download path as in conventional peer-to-peer methods, then file retrieval success ratio is improved, but bandwidth consumption and storage requirements increase significantly

Engineering Contradiction:
Improvefile retrieval success ratioVSAvoidbandwidth consumption
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent applies local quality by differentiating between wired nodes and wireless nodes in the network path. Wired nodes perform full data caching and forwarding, while wireless nodes only perform selective caching based on their limited bandwidth and storage capabilities. This localized differentiation allows the system to maintain file retrieval success while reducing overall bandwidth consumption, as wireless nodes do not unnecessarily cache and forward all data packets.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent segments the download path into different node types (wired and wireless) and applies different data handling strategies to each segment. Wired nodes handle complete data caching and forwarding, while wireless nodes handle only essential data transmission. This segmentation allows the system to optimize bandwidth usage by preventing wireless nodes from consuming excessive bandwidth on full data caching operations.

Inventive Principle:
Principle #1Segmentation

2Reliability

If data is cached in all nodes located in the download path, then file retrieval reliability is improved, but storage capability requirements increase

Engineering Contradiction:
Improvefile retrieval success ratioVSAvoidstorage capability
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent implements local quality by assigning different caching responsibilities to different node types. Wired nodes with sufficient storage capability cache complete file data, while wireless nodes with limited storage cache only essential metadata or selective data portions. This localized approach maintains file retrieval success by ensuring that at least some nodes along the path can fulfill retrieval requests, while avoiding the storage overhead of caching in all nodes.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent segments the network nodes into two categories: wired nodes that perform full data caching and wireless nodes that perform selective or minimal caching. This segmentation reduces total storage requirements by preventing wireless nodes from storing complete files, while still maintaining retrieval reliability through the distributed caching architecture across wired nodes.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If conventional peer-to-peer download methods are applied in wired and wireless integrated networks, then network compatibility is maintained, but download speed decreases due to wireless node limitations

Engineering Contradiction:
Improvenetwork compatibilityVSAvoiddownload speed
Core Design Contradiction:
Adaptability or versatilityVSSpeed

Solution Approach 1:

The patent applies dynamics by making the data caching and forwarding behavior adaptive to node type. Nodes dynamically determine their caching strategy based on whether they are wired or wireless. This dynamic adaptation allows the network to maintain compatibility with conventional peer-to-peer protocols while optimizing download speed by preventing wireless nodes from performing bandwidth-intensive full data caching operations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent uses local quality to optimize download speed by differentiating data handling at each node based on its characteristics. Wired nodes provide high-speed data caching and forwarding, while wireless nodes provide selective data transmission. This localized optimization improves overall download speed by ensuring that data flows efficiently through wired infrastructure while minimizing bottlenecks at wireless nodes.

Inventive Principle:
Principle #3Local quality

AI summary

A method of downloading data in a peer-to-peer service on a wired and wireless integrated network and a node therefore includes downloading the data to a requester node only through wired nodes among a plurality of nodes located in a download path between the requester node which requests the data and a holder node which has the data. Thereby, the file download rate can be improved, without reducing the retrieval success ratio according to the peer-to-peer method, and the storage space for the data of each node can be saved.
