Autonomous Storage Devices for Distributed Content Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for high-quality video content streaming, such as 4K resolution and 60 frames per second, combined with growing user bases, leads to significant network bandwidth challenges for content service providers and internet service providers, often resulting in traffic shaping that can degrade user experience.
Innovation Solution
The implementation of autonomous storage devices equipped with single-board computers and peer-to-peer file sharing clients, which distribute and manage content across a network, allowing for selective content retrieval from peers, including content service providers, internet service providers, and client devices, thereby reducing the burden on central servers and optimizing network traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If content service providers support high-quality video streaming with growing user bases, then content delivery quality is improved, but network bandwidth consumption increases significantly
Solution Approach 1:
The patent implements a distributed storage system where content is replicated across multiple nodes (storage devices, CDNs, and user devices). Instead of streaming content linearly from a single source, the system creates copies of content at various locations in the network, allowing multiple users to access content simultaneously without proportionally increasing total bandwidth consumption from the original source.
Solution Approach 2:
The patent segments content delivery into multiple paths through a hierarchical distributed storage architecture. Content is stored at different levels (local storage devices, regional CDNs, edge devices), and the system selectively retrieves content from the most appropriate segment based on user location and network conditions, reducing the burden on any single network path.
2Productivity
If ISPs perform traffic shaping to preserve bandwidth, then network congestion is reduced, but user experience quality deteriorates
Solution Approach 1:
The patent implements autonomous storage devices that automatically participate in content distribution without requiring ISP intervention. These devices autonomously retrieve content from the distributed network and serve it to users, effectively self-managing the content delivery process and eliminating the need for ISP traffic shaping while maintaining network efficiency.
Solution Approach 2:
The patent introduces autonomous storage devices as intermediary nodes between content sources and users. These intermediaries cache and distribute content locally, reducing the amount of traffic that needs to be managed by ISPs and eliminating the need for traffic shaping while preserving user experience quality.
3Device complexity
If content is distributed through traditional centralized servers, then content delivery is simple to implement, but network traffic becomes congested under high demand
Solution Approach 1:
The patent transitions from a single-level centralized server architecture to a multi-dimensional hierarchical distributed storage system. Content is stored and distributed across multiple layers (local devices, regional CDNs, edge devices, and users), adding spatial and hierarchical dimensions to the architecture that enable scalable content delivery without congestion.
Solution Approach 2:
The patent creates a universal distributed storage network where any device with storage capacity can participate in content distribution. The system treats storage devices, CDNs, user devices, and autonomous storage devices as equivalent participants in the distributed network, allowing flexible and efficient content routing through any available path.
Data Source
AI summary
Autonomous storage devices and methods are provided for distributing content, such as streaming content. An exemplary storage device comprises: a network interface for receiving requested content over a network; a non-volatile memory (NVM) for storing the content; and a single-board computer connected to the NVM and having an operating system with an installed peer-to-peer file sharing client and an installed data curation component. The data curation component stores and manages data in the NVM. An optional lightweight unikernel comprises a specialized machine image of the operating system to support the installed peer-to-peer file sharing client and the installed data curation component. A plurality of the storage devices can be interconnected in a local network of a content service provider and/or an Internet service provider and communicate with a peer-to-peer network composed of additional storage devices in an external wide area network that consume or replicate content.
