Overlay Network Content Acquisition Prioritizing Internal Nodes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Peer-to-peer communication systems face inefficiencies when there are fewer contents stored within a base, leading to increased reliance on external networks, which can result in longer content acquisition times due to limited external connections and narrow bandwidths.
Innovation Solution
An information communication system that prioritizes content acquisition within internal networks by using a support device to facilitate content exchange between node devices, reducing external network traffic through an overlay network that prefers local content sources, such as edge servers and user terminals within the same base over those outside the base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If peer-to-peer communication is implemented within a base using internal networks, then content acquisition speed within the base is improved, but the system becomes ineffective when there are fewer contents stored in terminal devices within the base
Solution Approach 1:
The system segments content acquisition into two distinct paths: internal network acquisition (preferred) and external network acquisition (fallback). The selection unit divides the acquisition process by first attempting to find content within the base's internal network, and only when that fails does it search external networks. This segmentation allows the system to maintain high speed when possible while preserving adaptability when internal resources are insufficient.
Solution Approach 2:
The selection unit acts as an intermediary between the terminal device and content sources. It mediates the content acquisition process by intelligently routing requests - first directing them to internal network devices (other terminal devices or edge servers within the base), and only when those cannot satisfy the request does it route to external networks. This intermediary function resolves the contradiction by dynamically choosing the appropriate path based on available resources.
2Reliability
If the system prioritizes external network access to ensure content availability, then content acquisition reliability is improved, but external network traffic increases and acquisition time lengthens due to limited bandwidth
Solution Approach 1:
The system performs preliminary action by first searching for content within the internal network before accessing external networks. The selection unit proactively checks if content exists among other terminal devices or edge servers within the base before initiating external network requests. This preliminary internal search reduces external network traffic and acquisition time while maintaining reliability, as external networks are only accessed when absolutely necessary.
Solution Approach 2:
The system applies local quality by prioritizing local (internal network) content sources over remote (external network) sources. The selection unit gives preference to content stored within the base's internal network, utilizing local resources first. This approach reduces external network traffic and acquisition time while maintaining reliability by falling back to external networks only when local resources are insufficient.
3Adaptability or versatility
If content is acquired from external networks when internal storage is insufficient, then content availability is improved, but the load on external connections increases
Solution Approach 1:
The system applies self-service by enabling terminal devices within the base to serve each other's content needs. When one terminal device requires content, the selection unit first checks if other terminal devices or edge servers within the same base have the content available. This self-service mechanism within the internal network reduces dependency on external networks, thereby reducing external network load while maintaining content availability through peer-to-peer sharing.
Solution Approach 2:
The system prioritizes local content sources (internal network devices) over remote sources (external networks). The selection unit is designed to exhaust local resources first before accessing external networks. This local quality approach ensures content availability is maintained through internal resources when possible, and only resorts to external networks when absolutely necessary, thereby minimizing external network load.

AI summary
An information communication system for exchanging a plurality of contents between a plurality of node devices, includes a plurality of internal networks connected to an external network. The internal networks include: the plurality of node devices connecting the same internal network; and a support device, which connects the internal networks, and which supports acquisition of contents by the node devices. An overlay network allows for exchanging of contents between the node devices and the support devices. The node devices include a first acquisition unit that acquires contents by selecting a first device group in preference to a second device group. The first device group includes: a support device and a node device connecting the internal network of an access destination that is a contents acquisition destination. The second device group includes a support device and a node device that do not connect the internal network of the access destination.
