Edge CDN Node Sharing for Video Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video transmission methods in mobile communications networks face challenges such as high bandwidth consumption, increased deployment costs, and inefficient storage due to the need for multiple Edge CDN nodes, which lack interaction and result in redundant storage of frequently accessed videos.
Innovation Solution
A method and apparatus for video transmission where requests are forwarded to other network devices, determining the retrieval method based on responses, allowing for local storage and sharing of frequently requested videos, thereby reducing bandwidth demands and deployment difficulties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If multiple Edge CDN nodes are deployed respectively for each video service provider, then video content can be buffered locally to reduce bandwidth consumption, but deployment cost and complexity increase significantly
Solution Approach 1:
The patent merges multiple Edge CDN nodes from different video service providers into a shared infrastructure. Instead of each provider deploying separate nodes, they share common Edge CDN nodes, which reduces deployment complexity while maintaining the ability to buffer video content locally to reduce bandwidth consumption.
Solution Approach 2:
The Edge CDN nodes are designed to serve multiple video service providers simultaneously, making them multi-functional. A single Edge CDN node can buffer and deliver video content for different providers, reducing the total number of nodes needed and simplifying deployment while still achieving bandwidth savings through local caching.
2Reliability
If each Edge CDN node buffers video content independently without interaction, then each node can serve its respective video service provider, but storage space is wasted due to redundant buffering of the same video
Solution Approach 1:
The patent combines the buffering functions of multiple Edge CDN nodes into a shared storage system. Video content is buffered once in the shared storage space and can be served to multiple video service providers, eliminating redundant storage while maintaining service availability through the shared cache.
Solution Approach 2:
Instead of each Edge CDN node creating independent copies of video content, the system uses a shared copy mechanism where video content is stored once and referenced by multiple providers. This reduces storage space utilization while ensuring service reliability through the shared buffer.
3Productivity
If Edge CDN nodes are deployed for each video service provider, then video content can be cached locally, but the same video must be buffered in each node causing storage waste
Solution Approach 1:
The patent merges the video buffering functionality across multiple Edge CDN nodes into a unified shared storage system. This allows video content to be delivered efficiently to multiple providers without duplicating storage, as the shared buffer serves all providers simultaneously, maintaining productivity while reducing total storage space requirements.

AI summary
An objective of the present invention is to provide a method and apparatus for video transmission, wherein the video is initially stored in one or more other network devices. The method comprises receiving a second request for a video from a user equipment; forwarding the second request to other network device corresponding to the second request; determining a manner of obtaining the video based on a response, received from the other network device, to the second request; and transmitting the video obtained based on the manner of obtaining the video to the user equipment. Compared with the prior art, by uniformly determining a manner of obtaining a video and transmitting the obtained video to the user equipment the present invention, the present invent on lowers deployment difficulty, reduces bandwidth resource demands, and enhances the video sharing degree.
