Micro-cache IP Management for Mobile Content Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current caching and Content Delivery Network (CDN) technologies require continuous high-speed connectivity to operate effectively, which is not available in mobile environments like airplanes, trains, and buses, leading to network congestion and unmet customer expectations for seamless content access.
Innovation Solution
The implementation of a micro-cache method and apparatus that augments existing connectivity with high-speed access points at strategic locations, using a Content Delivery Network (CDN) extender and intermediate storage devices to pre-load content, manage IP subnetworks, and distribute content efficiently even in low-bandwidth conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If caching and CDN technologies are used to deliver content in mobile environments, then content delivery efficiency is improved, but the requirement for continuous high-speed connectivity worsens network infrastructure demands and cannot be met in low-bandwidth mobile environments
Solution Approach 1:
The patent implements preliminary action by pre-loading content into micro-caches at strategic locations (airports, train stations, bus terminals) before users need access. The CDN extender proactively distributes content to these micro-caches during periods of high-speed connectivity, so that when users are in mobile environments with limited bandwidth, the content is already available locally for immediate delivery without requiring continuous high-speed connectivity.
Solution Approach 2:
The patent introduces an intermediary component - the micro-cache system with CDN extender - that acts as a mediator between the content delivery network and mobile users. This intermediary stores content locally at strategic locations and serves users even when disconnected from the main network, thereby reducing the demand for continuous high-speed connectivity while maintaining efficient content delivery.
2Reliability
If micro-cache with pre-loaded content is implemented, then content availability in low-bandwidth areas is improved, but storage requirements and device complexity increase
Solution Approach 1:
The patent applies local quality by deploying micro-caches at specific strategic locations (airports, train stations, bus terminals) rather than uniformly across all mobile environments. Each micro-cache is tailored to serve the specific user population and content needs of its location. The CDN extender intelligently determines which content to pre-load based on local demand patterns, optimizing storage utilization and reducing unnecessary complexity.
Solution Approach 2:
The patent segments the content delivery system into multiple distributed micro-caches rather than relying on a single centralized cache. This segmentation allows content to be distributed across multiple locations, reducing the storage burden on any single device while improving overall content availability. The CDN extender manages this segmented architecture by coordinating content distribution across the distributed micro-cache network.

AI summary
A system comprising: a plurality of micro-cache devices integrated within a corresponding plurality of mobile environments; an address manager to maintain an IP address pool in accordance with IP address information received from a content provider, the address manager to associate different portions of the address pool with different instances of the micro-caches and corresponding mobile environments; a first local network manager coupled to a first micro-cache to assign IP addresses from a first portion of the address pool to requesting client devices within a first mobile environment and a second local network manager coupled to a second micro-cache to assign IP addresses from a second portion of the address pool to requesting client devices within a second mobile environment, wherein the content provider is to be provided with visibility into each micro-cache and control of access rights to each micro-cache by the client devices within each mobile environment.
