Hierarchical Name Network Content Retrieval via Partial Prefixes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Networks based on destination addresses, such as IP protocols, face issues like traffic congestion due to popular content nodes and require network extensions as internet usage increases, while hierarchical name structure networks struggle with content retrieval when users have only partial or inaccurate hierarchical names, leading to resource inefficiency.
Innovation Solution
A communication method for content requesters and providers in a hierarchical name structure network that generates and transmits content search request packets with partial hierarchical names, using indicators for search areas, keywords, or metadata to facilitate content retrieval across virtual communities, allowing for content search and response without requiring the full hierarchical name.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the network uses full hierarchical names for content requests, then content retrieval accuracy is improved, but resource consumption increases and user accessibility decreases
Solution Approach 1:
The patent segments the full hierarchical name into two parts: a prefix (e.g., '/acme/video/') that identifies the content type and category, and a suffix (e.g., '/movie1.mp4') that identifies the specific content file. The request packet only needs to contain the prefix portion, which reduces the amount of data transmitted while still enabling accurate content retrieval through the hierarchical name structure's organizational properties.
2Measurement precision
If the network requires full hierarchical names for content requests, then content identification precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent applies partial action by requiring only the prefix portion of the hierarchical name (e.g., '/acme/video/') instead of the complete hierarchical name (e.g., '/acme/video/movie1.mp4'). This partial information is sufficient for the system to identify the content category and locate the requested content through the hierarchical structure, making the operation easier while maintaining identification precision.
3Measurement precision
If the network forwards packets based on full hierarchical names, then routing accuracy is improved, but device complexity increases
Solution Approach 1:
The patent extracts only the necessary prefix portion of the hierarchical name from the full path for routing purposes. The network nodes use this extracted prefix to determine the routing path through the hierarchical structure, while the complete hierarchical name resolution is handled by the endpoint devices. This extraction reduces the processing complexity at each network node while maintaining routing accuracy.

AI summary
Provided are communication devices and methods for requesting content in a network based on a hierarchical name structure. A content requester may search for content without the use of the entire hierarchical name of the content in the network based on the hierarchical name structure.
