WiMAX Tutorial

This is a continuation of the WiMAX Tutorial and Primer.

Prerequisites

This tutorial series assumes you have an ORBIT account, have scheduled a session on the ORBIT test bed, are familiar with SSH'ing into the test bed itself, and are familiar with the basics of running ORBIT experiments. If you have not done these things yet, you may wish to do so before taking a look at this slightly more advanced experiment. If you are unfamiliar with or are entirely new to ORBIT, you may wish to start here.

Difficulty

This tutorial is of intermediate difficulty. In addition to the knowledge from the previous tutorial, basic understanding of the ORBIT Experiment Description Language (OEDL) and its source language, Ruby (and especially blocks within Ruby), are strongly recommended. Furthermore, fluency in low-level computer networking concepts such as IP are assumed.


About This Experiment

This tutorial section is adapted from the tutorials at NYU-Polytech and expanded from the more concise ORBIT adaptations done previously. As before, we will perform our experiment on Sandbox 4, providing some background information at each step. For more information, see the relevant documentation for each step at one of the source websites.


Experiment: Check Connection Status, Then Send UDP Packets


The Code

The following are the links to experiment Description script and the underlying codes. In the interest of saving space, they are not posted directly to this page.

At this point, we will give a primer on OMF and some of the functions inside the experiment. To skip to the experiment itself, click here.


Background Information

Experiments performed on ORBIT (specifically) and all GENI wireless test-beds are managed by what was once called the ORBIT Management Framework, now simply known as OMF. (For background information on frameworks, see Wikipedia.) Simply put, a framework provides programs which perform all the generic functions a programmer would otherwise need to code at a given layer to obtain functional applications. This includes programs that check various paths, run subprograms, collect data, check validity, sanitize inputs, and more.
