multiRTT

multiRTT refers to a network measurement technique used to determine the round-trip time (RTT) between two points on a network. Unlike traditional RTT measurements that may provide a single, potentially noisy value, multiRTT utilizes multiple probes to establish a more robust and accurate estimate. This approach helps to account for variations in network latency that can occur due to congestion, routing changes, or other dynamic network conditions.

The core idea behind multiRTT is to send a series of packets and measure the time it takes for each packet to travel to the destination and return. By analyzing the RTT of these multiple probes, statistical methods can be employed to filter out outliers and derive a more reliable average. This can involve calculating the median, removing extreme values, or using other statistical techniques to smooth out the data.

The benefits of using multiRTT include improved accuracy in latency measurements, which is crucial for applications sensitive to delay such as real-time communication (VoIP, video conferencing) and online gaming. It can also aid in network troubleshooting by providing a clearer picture of network performance over time, helping to identify intermittent issues that might be missed by single-probe measurements. Tools that implement multiRTT often provide visualizations of RTT variations, allowing for deeper analysis of network behavior.
