TCP Fe<strong>at</strong>ures: Nagle’s algorithm<br />

End of the lab questions:<br />

37<br />

Examine the applic<strong>at</strong>ion response time <strong>and</strong> display a graph <strong>for</strong> the following four<br />

situ<strong>at</strong>ions:<br />

Nagle’s algorithm is disabled <strong>and</strong> inter-comm<strong>and</strong> time is set to 0.1 seconds.<br />

Nagle’s algorithm is enabled <strong>and</strong> inter-comm<strong>and</strong> time is set to 0.1 seconds.<br />

Nagle’s algorithm is disabled <strong>and</strong> inter-comm<strong>and</strong> time is set to 10 seconds.<br />

Nagle’s algorithm is enabled <strong>and</strong> inter-comm<strong>and</strong> time is set to 10 seconds.<br />

•How does the applic<strong>at</strong>ion response time vary when Nagle’s algorithm is enabled<br />

<strong>and</strong> when it is disabled? Why?<br />

•Which of the above four scenarios resulted in the lowest <strong>and</strong> in the highest<br />

applic<strong>at</strong>ion response time? Why?<br />
