V2ray-core is a modular network proxy engine designed to manage inbound and outbound traffic through a unified, rule-based processing pipeline. It functions as a background service that operates multiple concurrent network protocols within a single process, allowing for flexible traffic management and the independent handling of diverse communication streams.
The project distinguishes itself through a highly decoupled architecture that treats network protocols as swappable modules, enabling the encapsulation of various transport layers into a consistent stream-based model. It features a centralized configuration system that parses structured data to define complex routing, DNS, and transport rules at runtime. To enhance connectivity and security, the engine includes a load-balanced outbound dispatcher that distributes requests across multiple connections using weighted algorithms, alongside a traffic obfuscation layer that masks packet signatures to mimic standard web activity.
The software supports sophisticated network traffic routing, allowing users to direct packets based on domain names, IP addresses, or geographic regions. It provides comprehensive tools for both client and server deployments, enabling the establishment of secure communication endpoints across diverse network infrastructures.
The project provides source code for manual compilation and scripts for building distribution packages across various operating systems and hardware architectures. Operational parameters, including logging and service settings, are managed through structured configuration files provided at runtime.
