World of Computer Networking Your CCNA start - Measuring Round-trip Time (RTT) Using the Ping Utility

The video tutorial explains how to measure Round Trip Time (RTT) using a terminal application on different operating systems like Mac, Windows, and Linux. It demonstrates the process of pinging Google's DNS server to obtain RTT values and discusses the factors affecting these values, such as network conditions and packet routes. The tutorial also covers how to interpret RTT statistics, including minimum, average, and maximum times, and provides guidance on troubleshooting high RTT values. Finally, it introduces the concept of jitter as another network parameter to be discussed further.

Explain why different packets may have varying round trip times.

What should you do if you observe RTT values larger than 100 milliseconds?
