Hierarchical Network Routing via Linear Chain Intersection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing DNS system and Content Centric Networking (CCN) face inefficiencies such as overloading due to increased top-level domains, scalability issues, and reachability problems, particularly in delivering content quickly and efficiently across the internet, as they do not effectively leverage geo-locational hints or optimize content delivery from multiple sources.
Innovation Solution
A region-based hierarchical network using a linearly published character string for content requests, which allows content to be routed efficiently through a multi-tiered network, bypassing inefficiencies of the current DNS system by forming a logical linear chain intersecting each hierarchical level at a single point, enabling direct access to content sources and caching frequently requested content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If DNS resolution is used to resolve domain names to IP addresses, then content can be accessed through the internet, but the system becomes overloaded due to increased top-level domains and does not optimize content delivery speed
Solution Approach 1:
The patent segments the hierarchical network into multiple levels (first hierarchical level, second hierarchical level, etc.) with different functions. The first hierarchical level handles local content requests directly, while the second hierarchical level manages broader domain resolution and routing. This segmentation reduces the load on any single level and improves overall system reliability while maintaining fast content delivery.
Solution Approach 2:
The patent introduces a character string as an intermediary element that bridges domain names and IP addresses. The character string is published at multiple hierarchical levels, allowing content requests to be routed efficiently through the hierarchy without overloading the traditional DNS resolution process. This intermediary mechanism enables faster content delivery while distributing system load.
2Adaptability or versatility
If the DNS system is used for content distribution, then domain name resolution is achieved, but scalability issues arise and geo-locational hints cannot be effectively utilized
Solution Approach 1:
The patent adds a new dimension to content routing by publishing character strings at multiple hierarchical levels simultaneously. Instead of traditional single-level DNS resolution, the system creates a multi-dimensional routing structure where character strings exist at the first hierarchical level, second hierarchical level, and beyond. This enables geo-locational routing capabilities while the hierarchical structure manages complexity through organization rather than overwhelming the system.
3Productivity
If multiple content sources are added to speed up content delivery, then delivery performance improves, but the existing DNS system cannot easily support delivery from multiple sources
Solution Approach 1:
The patent makes the character string publishing mechanism universal by allowing character strings to be published at multiple hierarchical levels (first hierarchical level, second hierarchical level, etc.). This multi-functional approach enables the same character string infrastructure to support delivery from multiple content sources simultaneously, improving both delivery speed and adaptability to various content distribution scenarios.
Data Source
AI summary
A system and method are provided for routing content requests. On a given server network, content requests comprising a character string may be routed up a hierarchical network topology until a linear chain, corresponding to the character string, is identified. Thus, the content request is forwarded up the hierarchy until an intersecting server network is reached. Then the content request is forwarded down the hierarchy until, along a published linear chain corresponding to the character string, until a content source is reached. Content is provided to the requestor along a reverse path of the content request.
