Siirtosekunnit

Siirtosekunnit is a term used in Finnish-language telecommunications and computing literature to denote the total time, measured in seconds, required to transfer a data unit from a source to a destination. The word combines siirto (transfer) and sekunnit (seconds) and is used to discuss transfer latency in networks and data systems. The concept is applied to quantify how long a complete transfer takes, from initiation to completion, across all network layers and devices involved.

The siirtosekunnit can be decomposed into several delay components: propagation delay, serialization (transmission) delay, processing delay at devices, and queuing delay caused by contention. The total transfer time is conceptually the sum of these delays. In practice, measurement is performed by timestamping the start of a transfer and the moment the last packet or unit arrives at the destination, and subtracting to obtain the duration.

Use of siirtosekunnit is common in performance testing, capacity planning, and quality-of-service assessments. Lower values indicate faster transfers and are typical of high-capacity physical links, while higher values may reveal congestion, long distances, or processing bottlenecks. The metric is influenced by the medium (fiber, copper, wireless), network topology, and traffic patterns.

Siirtosekunnit is not a standardized international term; its meaning and usage are primarily observed in Finnish-language documentation and discussions. Analysts typically report it alongside related metrics such as throughput, latency, jitter, and packet loss to provide a complete view of transfer performance.
