Coturn is a network server that facilitates peer-to-peer media traffic for real-time communication applications. It functions as a relay platform for voice, video, and data transmission, enabling direct connections between clients located behind restrictive firewalls and network address translators.
The server implements standard network traversal protocols to manage media packet exchange and client authentication. It utilizes a multi-threaded architecture and event-driven polling to handle high-throughput traffic, while employing hash-based message authentication codes to verify client identity and secure access to relay services.
The platform includes a modular interface for persistent storage of credentials and server state across various database backends. It also provides integrated monitoring capabilities to track traffic volume, connection status, and operational health metrics, allowing for the identification of performance bottlenecks in distributed communication environments.
