Residential Cache Appliance for Social Network Content Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network traffic management systems, including content delivery networks and end-user device browser caches, fail to effectively alleviate network traffic bottlenecks and reduce redundant traffic, especially in client-server architectures, as they do not provide a global network effect and are limited in benefiting users with new content requests.
Innovation Solution
A residential caching system integrated with a social networking system that includes a caching appliance capable of loading balancing internet traffic by caching recently and popularly requested content, predicting content demand based on user profiles and global streaming patterns, and sharing cached content within local networks, while managing permission and privacy settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If content delivery networks cache content on distributed servers, then network traffic bottlenecks at the server end are partially relieved, but redundant traffic still flows between CDNs and servers
Solution Approach 1:
The patent segments the network caching function into two distinct layers: CDN servers handle popular content globally, while residential cache appliances handle local content sharing. This segmentation allows each layer to specialize, reducing redundant traffic between CDNs and origin servers while maintaining manageable complexity through clear functional division.
Solution Approach 2:
The patent adds a new dimension to content delivery by introducing peer-to-peer sharing at the residential level, transforming the traditional client-server model into a hybrid architecture. This dimensional addition allows content to flow horizontally between neighbors rather than only vertically through servers, reducing trunk bandwidth usage without requiring complete architectural overhaul.
2Ease of operation
If end-user device browser caches are used, then benefits are provided to specific end-users on repeated visits, but the global bandwidth problem is not solved due to lack of network effect
Solution Approach 1:
The patent merges the benefits of browser caching (local convenience) with the network effects of distributed caching. Residential cache appliances combine personal cache functionality with neighborhood-wide content sharing, allowing users to benefit from both rapid local access and the aggregated storage capacity of their social network, thereby solving both individual convenience and global bandwidth issues simultaneously.
Solution Approach 2:
The residential cache appliance serves multiple functions: it acts as a personal browser cache for the user, a content server for neighbors, a predictive pre-loader for anticipated content, and a social network node for coordinated caching. This multi-functionality allows a single device to address multiple problems (local access speed, global bandwidth consumption, content availability) without requiring separate systems for each function.
3Productivity
If residential cache appliances cache content locally, then peak bandwidth usage is reduced and content sharing among neighbors is enabled, but device complexity and permission management increase
Solution Approach 1:
The patent implements feedback mechanisms where the social network system monitors content access patterns, cache hit rates, and bandwidth usage across residential appliances. This feedback enables dynamic adjustment of caching strategies, predictive pre-loading based on social graphs, and automated permission management, reducing the perceived complexity for users while maintaining high network throughput efficiency through intelligent, adaptive operation.
Data Source
AI summary
Embodiments are disclosed for managing a distributed data center. The managing can include receiving content interaction history associated with a first social networking account of a social networking system at a content distribution system; maintaining a cache map of available cache appliances to implement a distributed cache store; selecting a content item to push to a residential cache appliance based on the content interaction history, wherein pushing the content item includes updating the cache map to associate a network address of the residential cache appliance with an identifier of the content item; and providing a content distribution service configured to redirect a content streaming request for the content item to the residential cache appliance when the content item is determined to be available in the distributed cache store according to the cache map.
