This document specifies Secure Reliable Transport (SRT) protocol. SRT is a user-level protocol over User Datagram Protocol and provides reliability and security optimized for low latency live video streaming, as well as generic bulk data transfer. For this, SRT introduces control packet extension, improved flow control, enhanced congestion control and a mechanism for data encryption.
