New IEEE Standard - Active - Draft. This standard defines the Streaming Telemetry Transport Protocol, STTP. This protocol is initially designed for streaming power system data over Internet protocol (IP) communication systems. It is focused on streaming real-time measurements but can be used with any type of continuously flowing data. It features built-in security and lossless data compression options for efficient transport. It specifies data types and transport control methods using a publish-subscribe architecture for controlled signal-level data access. It uses standard security and transport options, so it is easy to maintain and update. It is highly configurable for time precision, compression level, and packet sizes to optimize the stream within data and transport limitations. It has been proven and refined in several demonstration projects and production environments.
