Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional peer-to-peer networks face challenges in achieving low latency for real-time applications like virtual meetings and live-streaming due to high network traffic and latency caused by segment buffering and central tracker reliance, which is inefficient for immediate media data sharing.
Innovation Solution
A network controller generates configurations for peer-to-peer networks with semi-static media data routes and forward error correction, enabling direct data transmission and immediate reproduction without local buffering, reducing latency and storage requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional P2P networks use segment buffering and central tracker reliance for peer discovery, then peer coordination and resource sharing are enabled, but latency increases and real-time media transmission efficiency deteriorates
Solution Approach 1:
The patent extracts the peer discovery and coordination function from centralized trackers and implements it through distributed cryptographic proofs (DLEQ proofs) that enable peers to verify each other's legitimacy without relying on central authorities. This removal of centralized coordination points eliminates the latency associated with tracker communication while maintaining peer verification reliability.
Solution Approach 2:
The patent implements preliminary action by pre-establishing cryptographic credentials and proof mechanisms before peer connections are formed. Nodes prepare DLEQ proofs and cryptographic identities in advance, allowing immediate verification and connection establishment without waiting for tracker-mediated introduction, thus reducing latency while ensuring reliable peer coordination.
2Ease of manufacture
If P2P networks implement segment buffering for media data transmission, then data can be organized and managed efficiently, but storage requirements increase and immediate reproduction capability decreases
Solution Approach 1:
The patent implements self-service by enabling receiving nodes to directly reconstruct and reproduce media data from incoming streams without requiring buffering or pre-processing. The system is designed so that nodes can immediately utilize received media data for reproduction, eliminating the need for local storage of buffered segments while maintaining efficient data management through direct stream processing.
3Ease of operation
If P2P networks rely on central trackers for peer discovery, then peer connection establishment is facilitated, but network traffic increases and transmission efficiency decreases
Solution Approach 1:
The patent extracts the peer discovery function from centralized trackers and replaces it with a distributed cryptographic verification system. Nodes independently verify each other's legitimacy through DLEQ proofs and cryptographic credentials, eliminating the need for tracker-mediated peer discovery. This reduces network traffic by removing unnecessary communication with central coordination points while maintaining ease of peer discovery through direct cryptographic verification.
4Adaptability or versatility
If traditional P2P networks use direct connections between peers, then decentralized communication is enabled, but latency occurs due to multiple hops and lack of optimized routing
Solution Approach 1:
The patent implements preliminary action by pre-establishing cryptographic credentials and connection parameters before actual media transmission begins. Nodes prepare their cryptographic identities and verification proofs in advance, allowing immediate connection establishment and data transmission without delays for credential verification during active communication. This maintains decentralized adaptability while improving transmission speed through pre-prepared connection states.
