Measuring Round-Trip Time (RTT) Between Internet Hosts: Program and Prediction Model

This assignment involves developing a program to measure the round-trip time (RTT) between two end hosts on the Internet, utilizing a wrapper for the ping command. You are required to collect several RTT measurements, analyze the variability of the samples, and propose a predictive model for future RTT values. Additionally, strategies for reducing RTT variability should be discussed. Submissions must include source code, RTT outputs, and a report detailing your findings and model, preferably using Perl. Deadline is Wednesday, Sept 3, 11:55 PM.

Presentation Transcript

  1. Assg #1: Measuring RTT • Write program to measure round-trip time between two end host on the Internet; • Refer to ping: write a simple wrapper program.. • Propose a model for RTT prediction, i.e., give a sequence of RTT measures, estimate the next RTT value. • Measure several values of RTT. What can you say about the samples? If they are variable, what can you do to reduce the variability of the RTT estimate? • Time series model 1

  2. Submission • Submissions from each person to WebCT: • Source code; • Measured RTT outputs; • Report (i.e., RTT prediction model) • All in text format. • Use of perl script is strongly encouraged. • Due next Wednesday Sept 3, 11:55pm Shivkuma@ecse.rpi.edu
