Local Content Caching Access Points for Last-Mile Delivery Bottlenecks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of delivering large digital content, such as video, to client devices is exacerbated by the 'last mile' network between the Internet Service Provider and the client device, despite improvements in Internet infrastructure, leading to high demand and costly networking needs.
Innovation Solution
A Content Delivery System comprising a Content Access Point with local content caching and wireless connectivity, a Client Application for initiating downloads, and Dedicated Web Services for authorization and management, enabling fast and secure content delivery directly to mobile devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If content is delivered through traditional ISP network infrastructure, then content can reach a wide area, but the last mile network becomes a bottleneck causing slow delivery speed and high latency
Solution Approach 1:
The system pre-loads content onto local caching devices (Content Access Points) before users request it. These devices are strategically positioned in locations where users frequently access content, such as public spaces, airports, and commercial establishments. When users need content, it is already available locally, eliminating the need for real-time transmission over the last mile network and thus reducing delivery latency and improving speed.
Solution Approach 2:
The patent introduces local caching devices as intermediary nodes between the central content delivery network and end-user devices. These intermediaries store content locally and serve it directly to users, bypassing the congested last mile network infrastructure. This intermediary layer effectively decouples content delivery speed from the limitations of the ISP's network infrastructure.
2Productivity
If more networking infrastructure is invested to improve content delivery, then bandwidth increases, but the cost of networking becomes prohibitively expensive
Solution Approach 1:
Instead of investing in expensive additional network infrastructure to increase bandwidth, the system creates local copies of content on caching devices. These copies are distributed to multiple locations, allowing simultaneous service to multiple users without requiring proportional increases in network capacity. This copying strategy increases content delivery capacity while avoiding the high costs of expanding the core network infrastructure.
Solution Approach 2:
The local caching devices autonomously manage content storage, retrieval, and delivery without requiring continuous control or investment from the central network operator. Once content is loaded onto these devices, they independently serve users locally, eliminating the need for ongoing networking investments to maintain delivery capacity. The system effectively self-serves content delivery needs at the local level.
3Speed
If content is cached locally on devices, then delivery speed improves, but the device complexity and infrastructure requirements increase
Solution Approach 1:
The patent designs caching devices with multi-functionality to reduce overall system complexity. These devices not only cache content but also provide wireless access points, authentication services, and content management capabilities. By consolidating multiple functions into single devices, the system achieves fast local content transfer without proportionally increasing device complexity. The universal design allows standard devices to serve multiple purposes in the content delivery ecosystem.
