Construction and Implementation Theory of a Low-Latency High-Reliability Dedicated Translation Layer (DTTL) — Logical Separation from General Networks and Protocol Optimization for Real-Time Language Synchronization —

This paper proposes a Dedicated Translation Layer (DTTL) that dynamically separates translation traffic from general network communication to achieve ultra-low latency and high reliability. By enabling terminal-driven switching upon translation mode activation, the system prioritizes translation data, minimizes jitter, and ensures stable real-time communication without requiring additional hardware in earphones. A mathematical latency model and entropy-based evaluation framework are introduced to guarantee performance within human perceptual limits. This architecture transforms translation from a software function into a network-level infrastructure, enabling seamless real-time language synchronization.
