What is the out-of-band protocol?

By utilizing out-of-band control, network protocols can efficiently manage various aspects of data transmission, including Flow control, error correction, and session management. This mechanism facilitates smoother communication and reduced complexity in the overall network architecture.

One prominent protocol that incorporates out-of-band control is the File Transfer Protocol (FTP). FTP, widely used for transferring files over the internet, employs this technique to separate control commands from the actual file data being transferred.

Out-of-band control represents a distinctive feature in network protocols, wherein the management of data Flow adheres to a unique paradigm. This method of control enables the segregation of control data from the primary data stream, fostering enhanced efficiency and flexibility.

The separation of control and data streams in FTP allows for the seamless execution of control operations, such as establishing connections, authenticating users, and navigating file systems, without impeding the Flow of file data.
