Multi-Network Flow Switching for P2P Video Freezing Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Video freezing phenomena often occur during network flow switching in video applications due to poor transmission quality, especially when Peer-to-Peer (P2P) flows cannot be switched to another network.
Innovation Solution
An electronic device employs multiple network interface cards to dynamically switch data flows based on their characteristics and quality, ensuring high-quality flows are transferred via alternate networks when the current network deteriorates, while retaining P2P flows on the original network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data flow switching is performed based on network quality deterioration, then video transmission quality is improved, but P2P flows cannot be switched to another network causing video freezing
Solution Approach 1:
The patent segments data flows into different types (video flows and P2P flows) and applies different switching strategies to each type. Video flows are switched to alternate networks when quality deteriorates, while P2P flows are handled separately to avoid freezing issues, thus resolving the contradiction between improving video quality and maintaining P2P flow adaptability
2Reliability
If all data flows are switched to another network when current network quality is poor, then video freezing is reduced, but network complexity increases due to multiple interface cards
Solution Approach 1:
The patent implements dynamic flow switching where the switching decision is made based on real-time network quality assessment and flow type identification. Not all flows are switched uniformly - only video flows are switched when quality deteriorates, while P2P flows maintain their original network path, thus reducing unnecessary switching complexity while maintaining video stability
3Reliability
If flow switching is performed without considering flow characteristics, then network quality is improved, but video freezing occurs due to improper switching of specific flow types
Solution Approach 1:
The patent applies local quality by treating different flow types differently based on their characteristics. Video flows receive quality-based switching treatment while P2P flows receive different handling. This localized approach to flow management prevents video freezing caused by inappropriate P2P flow switching while maintaining overall network quality

AI summary
This application provides a network acceleration method, an electronic device, a chip system, and a storage medium, and relates to the field of network communication technologies, so as to reduce freezing phenomena during video playback. The method includes: When an electronic device runs an application that does not include a P2P flow, a data flow that requires high network quality may be switched to another network with better quality when quality of a currently used network is poor. When the electronic device runs an application that includes a P2P flow, and when a currently used network is poor, because it is difficult to switch the P2P flow to another network with better quality, all data flows of the electronic device may be switched to the another network, thereby reducing video freezing phenomena caused by a difficulty of switching the P2P flow to the another network with better quality.
