Learning Support Server with P2P Data Offload for Real-Time Classes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional learning support systems face efficiency issues when a large number of terminals access the server or require transmission of large amounts of data, leading to potential access failures and delays.
Innovation Solution
Implementing a peer-to-peer (P2P) communication mode using WebRTC for direct data transmission between terminals, allowing them to bypass the server for real-time classes and large data transfers, while maintaining server management for other operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all data transmission passes through the server, then centralized management is achieved, but server load increases and access failures occur when many terminals connect
Solution Approach 1:
The patent segments data transmission into two paths: control data (learning histories, material distribution) passes through the server for centralized management, while real-time interaction data (voice, video, chat) transmits directly between terminals via P2P communication. This segmentation resolves the contradiction by distributing transmission loads appropriately.
Solution Approach 2:
The server acts as an intermediary that establishes P2P connections between terminals without handling all data traffic. It mediates control functions while allowing direct terminal-to-terminal communication for real-time data, reducing server load while maintaining management capability.
2Ease of operation
If large amounts of data are transmitted through the server, then centralized control is maintained, but transmission delays occur
Solution Approach 1:
The patent divides data into control data (managed centrally through server) and real-time interaction data (transmitted directly between terminals). This segmentation enables fast P2P transmission for large data while maintaining centralized control for management functions.
Solution Approach 2:
The patent extracts real-time interaction data transmission from the server-based communication path and establishes direct P2P channels. This extraction removes the bottleneck from high-speed data transmission while preserving server control over non-real-time operations.
3Device complexity
If the server manages all terminal connections, then system management is simplified, but access failures occur during server overload
Solution Approach 1:
The patent segments communication functions: the server handles connection management and control data, while P2P direct connections handle real-time data transmission. This reduces server overload and improves access reliability during high-traffic scenarios.
Solution Approach 2:
The server serves as a connection intermediary that facilitates P2P links without being the transmission path. This intermediary role maintains simplified management while preventing server overload from real-time data traffic.
