ProtokollID

Protokollid is a term used in computer networking and software engineering to denote a unique identifier associated with a protocol instance, a protocol version, or a communication exchange. The concept helps distinguish between different protocol definitions and different sessions or message sequences that share a common protocol.

In specifications, a Protokollid may identify a particular protocol version or profile. In runtime, it can accompany messages in headers or envelopes to bind related traffic together, enabling correlation, debugging, auditing, and traceability across distributed components.

Common implementations rely on universally unique identifiers (UUIDs/GUIDs), numeric counters, or cryptographic hashes. The Protokollid is typically transmitted in a dedicated field in the protocol header or in the message envelope. For stateless interactions, it supports request–response correlation; for stateful interactions, it tracks a session or transaction.

Applications span APIs, messaging systems, IoT protocols, and secure channels, where a Protokollid aids monitoring, error reporting, replay protection, and version negotiation. It is often used together with a Protokollversion (version) to formalize protocol compatibility.

Design considerations include ensuring global uniqueness, minimizing privacy impact, managing lifecycle, and handling id rotation or revocation. Interoperability requires clear naming conventions and consistent handling of unknown or legacy identifiers. The term Protokollid is not universally standardized; many systems implement similar concepts under names such as protocol identifier, message ID, or version tag.
