What is a good round-trip time?Įvery type of application will have its own requirements and it’s almost impossible to give a concrete time. RTT includes the processing delay at the echo endpoint. The latency is not definitely equal to half of the RTT, because the latency may be asymmetric between any two given endpoints. Latency is the time required for a data packet to travel from the sending endpoint to the receiving endpoint (only one trip). Network latency is closely related, but different from RTT. In contrast, RTT is measured at the application layer (layer 7 of OSI/ISO) and includes additional processing delays caused by higher-level protocols and applications (e.g. Although ping time can provide a good RTT estimate, the difference is that ping tests are usually performed within a transport protocol that uses ICMP packets. Round-trip time and ping time are sometimes considered synonymous. This time delay includes propagation times for the paths between the two communication endpoints. In networking, round-trip time ( RTT), also known as round-trip delay time ( RTD) is defined as a metric that measures in milliseconds the amount of time it takes for a data packet to be sent plus the amount of time it takes for acknowledgement of that signal to be received. RTT can be directly impacted by a range of architecture design decisions, especially by your network topology. Round-trip time is an important metric in networking that can indicate the quality of communications between two endpoints.
