Peer-Managed Content Distribution for High-Demand Live Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing content delivery networks (CDNs) struggle to provide consistent quality of service (QoS) for live content delivery, especially when a large number of users access the same event simultaneously, leading to issues like buffering and lag due to network saturation.
Innovation Solution
A synthetic peer-managed network is formed by self-organizing clusters of nodes that distribute content and aggregate data, where each node maintains persistent connections with peers and shares content based on its capacity and relationship, allowing for dynamic adjustment and efficient content distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a static CDN is used for live content delivery, then network infrastructure is simplified, but quality of service deteriorates under high demand
Solution Approach 1:
The patent transforms the static CDN architecture into a dynamic peer-managed network where nodes can dynamically join, leave, and reconfigure connections based on demand. Nodes automatically establish peer relationships and adjust content distribution paths in real-time, enabling the system to adapt to fluctuating traffic patterns and maintain QoS under high demand without requiring complex pre-configured infrastructure.
Solution Approach 2:
The peer-managed network enables nodes to self-organize and self-manage content distribution without centralized control. Each node autonomously establishes connections with peers, requests content pieces, and shares available content, creating a self-regulating system that automatically scales to meet demand while maintaining simplified infrastructure.
2Reliability
If each user connects to an edge server for live content, then content delivery is reliable, but network saturation occurs under high demand
Solution Approach 1:
The patent segments content into multiple pieces and distributes them across a peer network rather than delivering complete content through single edge servers. Each peer node holds and shares specific content pieces, allowing multiple users to simultaneously access different segments of content through different peer paths, thereby distributing bandwidth demand across the network and preventing saturation.
Solution Approach 2:
The patent combines multiple peer nodes into a distributed content delivery system that functions collectively as a virtual edge server. By merging the capabilities of multiple peers to store, share, and transmit content pieces, the system achieves reliable content delivery while distributing the bandwidth burden across all participating nodes rather than concentrating it on centralized edge servers.
3Device complexity
If users are clustered in limited local networks, then network infrastructure is simplified, but local network saturation occurs
Solution Approach 1:
The patent extends content distribution from a two-dimensional local network scope to a multi-dimensional peer network that spans across multiple local networks. Nodes can establish connections beyond their immediate local network, creating additional dimensional pathways for content flow. This allows users in clustered local networks to access content through peers in other networks, effectively distributing bandwidth demand across multiple network dimensions and preventing local saturation.

AI summary
A synthetic peer-managed content delivery network self-organizes for the purpose of accessing one content item or a limited number of content items. A node joins the network at an identified attachment zone by requesting connections with existing nodes associated with the zone. Connected nodes become peers. The node may attempt to achieve a maximum number of peer connections, including upstream peers one hop closer to a root node, midstream peers the same distance from the root node, and downstream nodes one hop further from the root node. The content item is shared (in pieces or components if necessary) from a given peer to its midstream and downstream peers. Each node regularly informs its peers of its status regarding the content item and, to help organize the network, indicates whether its connected peers are able to accept a new peer connection.
