Overview What You Will Learn Curriculum Instructor

Lab Description

Imagine you're a network administrator tasked with resolving slow web application performance and intermittent network issues. Users are experiencing noticeable delays when accessing the company’s web platform. Suspecting underlying network problems, you turn to Wireshark for a comprehensive packet-level investigation.

In this lab, you will begin by capturing and examining HTTP request and response sequences to detect irregularities or delays in the application’s communication. You’ll use Wireshark to filter and analyze TCP retransmissions and signs of packet loss—common culprits of performance degradation. Furthermore, the lab guides you in evaluating TCP packet delays and latency to uncover issues such as bottlenecks or network congestion that contribute to sluggish performance. By simulating these real-world diagnostic steps, this lab helps you build critical skills in pinpointing and resolving network and application efficiency problems effectively.
