Homework Lab 2<br />
In this lab you will finish our analysis of the selected <strong>TCP</strong> flavors <strong>and</strong> compare their response to<br />
three packet drops from the same window of data.<br />
Main Steps<br />
• Analyze <strong>TCP</strong> Tahoe behavior<br />
• Analyze <strong>TCP</strong> New Reno behavior<br />
• Analyze <strong>TCP</strong> Reno with ECN support behavior.<br />
• Compare response time across scenarios.<br />
Analyze <strong>TCP</strong> Tahoe<br />
2. Select Scenarios -> Switch to Scenario to switch to scenario Tahoe.<br />
3. <strong>TCP</strong> Tahoe supports fast retransmission <strong>and</strong> resets the congestion window to one MSS after<br />
segment retransmission. Check that Fast Retransmission is enabled <strong>and</strong> Fast Recovery is<br />
disabled. Your <strong>TCP</strong> settings on the workstation <strong>and</strong> server are shown below.<br />
