v38 v39 19 19 == About This Experiment == 20 20 21 This tutorial section is adapted from the tutorials at [http://witestlab.poly.edu/index.php/tutorial.html NYU Poly WITest lab] and expanded from the more concise [http://wimax.orbit-lab.org/wiki/WiMAX/30/07#a18.GEC13:TutorialsfromPolyNYU 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. '''This experiment uses OMF Version 5.3, also known as omf-5.3. This experiment very well may fail for other versions of OMF.'''21 This tutorial section is adapted from the tutorials at [http://witestlab.poly.edu/index.php/tutorial.html NYU Poly WITest lab] and expanded from the more concise [http://wimax.orbit-lab.org/wiki/WiMAX/30/07#a18.GEC13:TutorialsfromPolyNYU ORBIT adaptations] done previously.

The principle parameter is the URI of the predefined application. 79 80 80 * The ''wimaxcu_app'' application is actually already installed in the experiment image here, and "test:app:..." instructs OMF to search in the /test/app/ subdirectory of its primary directory of applications.81 * The ''wimaxcu_app'' application tells OMF to load the application described in the ''wimaxcu_app.rb'' - in this case, the ''wmxstat'' application. 81 82 82 83 * ''app.measure('status_link')'' tells this application to use its predefined code to measure the 'status_link' property. OML will save these data for later. The exact behavior of this application is outside the scope of this discussion; suffice it to say that the implementation of the application is defined in the ''wimaxcu_app.rb'' and ''wmxstat'' programs mentioned previously. … … 85 86 #!ruby 86 87 node.addApplication("test:app:iperf") do |app| 87 app.setProperty('client', '10.41.14. 4', true)88 app.setProperty('client', '10.41.14.6', true) 88 89 app.setProperty('mss', 536) # Do not raise above 600 89 90 app.setProperty('interval', 1) 90 app.setProperty('bind', "10.41.14. 1")91 app.setProperty('bind', "10.41.14.4") 91 92 app.measure('TCP_Info', samples => 1) 92 93 end 93 94 }}} 94 95 95 * As before, this application is contained in a subdirectory accessed through ''/test/app/''.96 96 97 97 This adds the ''iperf'' application functionality to the group.
