Network Fundamentals 9-5: DEMO: Wireshark, Ephemeral Ports

📡 Capturing Traffic: Start by monitoring your Ethernet connection with Wireshark. Now, let's generate some web traffic by opening a browser and navigating to our demo Pi site.

🔍 Observing TCP Connections: Notice the TCP connection established, with an ephemeral port like 60959. This port serves as the source port for communication.

🔄 Reusing Connections: Open another tab in the browser and visit another page on the same site. You'll see that it uses the same ephemeral port for communication, indicating that the browser is reusing the existing connection.

🌐 Testing with Different Browsers: Now, let's try opening a new browser (like Edge) and visiting the same site. You'll observe a new ephemeral port being used for communication, as Edge establishes its own TCP connection.

🔄 Application-Level Connection Management: Chrome demonstrates the capability to reuse connections for different pages within the same browser session. However, when switching browsers, a new TCP connection is established, resulting in a different ephemeral port being used.
