odotusviiveet

Odotusviiveet is a Finnish term used to describe delays experienced while waiting for a result, response, or service. The term is composed of odotus (waiting) and viiveet (delays). It serves as a generic label for latency affecting users or systems and is used across information technology, telecommunications, and service studies.

In technology, odotusviiveet refers to the time from when a request is issued to when the response is received, including propagation, transmission, queuing, and processing delays. It distinguishes peak and average values and can be measured as round-trip time or one-way latency; jitter denotes the variation in delay.

The concept also applies to non-technical contexts, such as customer service, manufacturing, and web applications, where long odotusviiveet can degrade user satisfaction and throughput. In performance analysis, it is often studied using queueing theory and distribution models.

Measurement and interpretation: odotusviiveet are estimated from logs or probes. Common metrics include mean, median, and percentile values (e.g., 90th or 95th percentile). Data collection should consider sampling frequency and clock synchronization to ensure accuracy.

Reduction strategies: caching, load balancing, content delivery networks, data compression, protocol optimizations, and capacity planning can reduce odotusviiveet. Design choices should aim to minimize variability to improve perceived performance.
