round-trip time


Also found in: Acronyms.

round-trip time

(RTT) A measure of the current delay on a network, found by timing a packet bounced off some remote host. This can be done with ping -s.

However the net effect is to measure round-trip time and throughput, then use that core KPI measurement to derive latency, time to first byte, time to last byte, availability, and more.
The beam rebounds back to Global Surveyor, and the altimeter measures the elapsed round-trip time and estimates the elevation.
However, the arrival of the return pulse from the second target is delayed from the first return by twice the target separation divided by the speed of light - because the round-trip time from the range of the first target to the range of the second target is added.
Round-trip time, not including stopovers, is about 90 minutes.
Over networks with high round-trip time and packet loss, these applications suffer from extremely slow and unpredictable performance due to the design gap of TCP-based protocols, even with modern acceleration technologies.
Detailing all link speeds (delivery speed and provisioned speed), expected round-trip time and jitter.
For example, the round-trip time between Singapore and Japan is about 100 milliseconds, and the round trip between North America and Japan is about 200 milliseconds.
In TFRC, the transmission rate is determined by a function of packet loss rate, round-trip time (RTT), and packet size; this aims to achieve a long-term and steady performance of TCP.
The scientists collect data on the round-trip time and path followed as each packet hops from computer to computer to get to its destination.
Because of the problems that can occur between client and server in larger networks, it is imperative that service levels be based on the total round-trip time for application-level transactions.
This results in a doubling of the window in each round-trip time.
The laser output becomes a series of very short pulses, each separated by the round-trip time of the laser cavity, typically about 13 nsec.
