UDP Stream Test: Measuring latency and timely data delivery with uni-directional traffic

July 18, 2024 | by Anna Llagostera

Real-time applications often use unidirectional UDP packet streams sent from servers to clients or vice versa. The new UDP Stream Test can provide insight into detailed per-packet latency values and overall mobile network reliability to transport these streams seamlessly in such scenarios. This test can be widely parametrized to match real-world use cases with constant packet streams or varying load patterns.
