What Is Round-trip Time (RTT) in Networking?

November 20, 2023

Round-trip time (RTT) in networking is the interval it takes a network request to go from a source to a destination and back. It is expressed in milliseconds (ms).

RTT is influenced by propagation, transmission, processing, and queueing delays. Low RTT is preferred for responsive network applications, while high RTT can cause sluggishness. RTT helps with pinpointing network issues and optimizing performance.
