Name : coturn Product : Fedora 30 Version : 4.5.1.1 Release : 3.fc30 URL : https://github.com/coturn/coturn/ Summary : TURN/STUN & ICE Server Description : The Coturn TURN Server is a VoIP media traffic NAT traversal server and gateway. It can be used as a general-purpose network traffic TURN server/gateway, too.
This implementation also includes some extra features. Supported RFCs:
TURN specs: - RFC 5766 - base TURN specs - RFC 6062 - TCP relaying TURN extension - RFC 6156 - IPv6 extension for TURN - Experimental DTLS support as client protocol.
STUN specs: - RFC 3489 - "classic" STUN - RFC 5389 - base "new" STUN specs - RFC 5769 - test vectors for STUN protocol testing - RFC 5780 - NAT behavior discovery support
The implementation fully supports the following client-to-TURN-server protocols: - UDP (per RFC 5766) - TCP (per RFC 5766 and RFC 6062) - TLS (per RFC 5766 and RFC 6062); TLS1.0/TLS1.1/TLS1.2 - DTLS (experimental non-standard feature)
Supported relay protocols: - UDP (per RFC 5766) - TCP (per RFC 6062)
Supported user databases (for user repository, with passwords or keys, if authentication is required): - SQLite - MySQL - PostgreSQL - Redis
Redis can also be used for status and statistics storage and notification.
Supported TURN authentication mechanisms: - long-term - TURN REST API (a modification of the long-term mechanism, for time-limited secret-based authentication, for WebRTC applications)
The load balancing can be implemented with the following tools (either one or a combination of them): - network load-balancer server - DNS-based load balancing - built-in ALTERNATE-SERVER mechanism.
