CDNE Mobile Edge Cache Pre-loading for Connectivity Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current caching and Content Delivery Network (CDN) technologies require continuous high-speed connectivity, which is not available in mobile environments like airplanes, trains, and buses, limiting network access and bandwidth for passengers.
Innovation Solution
Implementing a Content Delivery Network Extender (CDNE) that uses strategic high-speed access points and intermediate storage devices to pre-load content, allowing caching and distribution even in low-speed connectivity scenarios by managing IP subnetworks and utilizing Interior Gateway Protocol (IGP) for routing, and deploying Content Service Providers (CSPs) to manage mobile environments as connected subnetworks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If continuous high-speed connectivity is required for caching and CDN technologies, then content delivery efficiency is improved, but network accessibility in mobile environments deteriorates
Solution Approach 1:
The patent implements preliminary content aggregation at strategic high-speed access points before mobile environments need the content. Capacitors pre-load and store content during periods when high-speed connectivity is available, then make it available later when mobile devices need it but high-speed connectivity is unavailable. This resolves the contradiction by performing content delivery preparation in advance during favorable network conditions.
Solution Approach 2:
The patent introduces capacitors as intermediary storage devices between content sources and mobile devices. These capacitors act as mediators that buffer content during high-speed connectivity periods and release it during low-speed periods, decoupling the content delivery process from continuous high-speed connectivity requirements and enabling network accessibility in mobile environments.
2Reliability
If content is pre-loaded at strategic high-speed access points, then network access consistency is improved, but infrastructure complexity increases
Solution Approach 1:
The patent makes mobile devices serve multiple functions: they act as both end-user devices and as distributed cache nodes. Mobile devices store content locally and can serve other mobile devices in the same environment, eliminating the need for dedicated capacitor infrastructure at every location and reducing overall system complexity while maintaining network access consistency.
Solution Approach 2:
The patent merges the functions of content consumption and content storage into mobile devices themselves. Instead of separating capacitors as distinct infrastructure elements, the system combines caching functionality with mobile devices, reducing infrastructure complexity while ensuring content availability through local storage and peer-to-peer sharing.
