Network Latency
Definition
Network latency measures the delay on a defined transmission path.
The transit time of data between sender and receiver. It must be specified as one-way delay or round-trip time with measurement direction and measurement point.
Simply explained
It describes how long data is in transit before arriving at the measured destination.
Why it matters in practice
Helps develop and operate digital systems robustly, securely, and maintainably.
Example from business
An API responds slowly despite fast computation because multiple remote network paths are traversed.
Limits and pitfalls
- Confusing latency with throughput or considering only one measurement location and the average.
Origin & history
Latency is a fundamental metric of communication networks and is often measured as one-way delay or round-trip time.
Use in mid-sized companies
- Possible example: An API responds slowly despite fast computation because multiple remote network paths are traversed.
