## RTT Formula

The following formula is used to calculate the round trip time of a small packet traveling across a network.

RRT = AVRTTs + AVRTTc

- Where RRT is the round trip time
- AVRTTs is the average round trip time to the server
- AVRTTc is the average round trip time to the client

The average round trip times can further be broken down into the following equations:

AVRTTs = (RTTs1 + RTTs2) / 2

AVRTTc = (RTTc1 + RTTc2) / 2

- Where RTTs and RTTc are the round trip times of the server and client respectively

## Example Problem

**How to calculate RTT? **

First, determine the average round trip time of the server. in this example, we will use a value of 7.354.

Next, determine the average round trip time of the client. in this problem, we will use a value of 4.568.

These values are arbitrary for this example to make it more simple.

Finally, calculate the RTT using the formula above:

RRT = AVRTTs + AVRTTc

RRT = 7.354 + 4.568

RRT = 11.922
