Kontrollinformation

Kontrollinformation is a term used across various fields to describe data that is used to manage, coordinate, or verify the operation of a system, process, or communication. It refers to information that guides actions, checks correctness, or enables control, rather than content intended for end users. The concept often overlaps with metadata, control signals, and protocol-specific fields.

In telecommunications and data transmission, kontrollinformation comprises headers, sequence numbers, addressing, and error-detection codes. This information allows networks to route data correctly, manage flow, ensure integrity, and coordinate retransmission when needed. In software and hardware engineering, it includes control messages, status bits, and other protocol data that govern interactions between devices or components.

In manufacturing, kontrollinformation (a related spelling in some Nordic languages) can denote instructions, calibration data, tolerances, and acceptance criteria used to steer processes and verify outputs. In data governance and information management, it encompasses metadata, lineage, access controls, and quality rules that regulate data usage and auditing.

Security and reliability considerations often treat kontrollinformation as separate from user content, sometimes applying encryption or isolation to protect critical control data from tampering. Because the term is broad and language- and domain-dependent, its exact meaning varies by industry and standard. In practice, it is best defined within the specific context of a system or protocol being described.
