[[TOC(Tutorials/c0WiFi*)]] == Wifi Tutorial: Access point with multiple clients == This tutorial shows how an experiment script configures an access point (AP) and multiple clients for performance testing with iperf. In this experiment script, we'll use an OMF feature to define an application header for iperf and run this application on the AP and access points. === Experiment Script === The experiment script is shown below. Near the top of the script we define an application header for iperf. After which we define two groups - the first group (AP) consists of a single node to be configured as an access point. The second group (client) can be a single or multiple node(s) that will be configured as !WiFi clients. Both groups add the iperf application and configure the wireless interfaces accordingly. At the bottom of the script, the nodes in all the defined groups are brought up and the applications are executed. {{{ 1 # 2 # Tutorial experiment 3 # 4 defProperty('accesspoint', 'node1-1', "node ID for access point") 5 defProperty('client', 'node1-2', "node ID for client nodes") 6 defProperty('duration', 60, "Seconds to run the application.") 7 8 defApplication('iperf', 'iperf-oml2') do |app| 9 10 app.version(2, 10, 0) 11 app.shortDescription = 'Iperf traffic generator and bandwidth measurement tool' 12 app.description = %{Iperf is a traffic generator and bandwidth measurement 13 tool.

4-6 we use ''defProperty'' to define a few experiment properties along with default values which allows the script to be executed with arguments passed from the command line. * From Lines 8 - 146 we use ''defApplication'' to define the application header for iperf. Here we defined a reference name ''iperf'' that can be used later in the script. {{{ defApplication('iperf', 'iperf-oml2') do |app| }}} The actual path to the iperf application in the node is defined. {{{ app.path = "/usr/bin/iperf-oml2" }}} The numerous ''defProperty'' that follows defines a reference to the various arguments for the application. In the following definition the reference name ''interval'' is mapped to the application argument specified with the ''-i'' flag. The default value and the other properties can also be specified. {{{ app.defProperty('interval', 'pause n seconds between periodic bandwidth reports', '-i', :type => :double, :unit => "seconds", :default => '1.') }}} * We define a reference name ''AP'' for the access point node using ''defGroup'' {{{ defGroup('AP', property.accespoint) do |node| node.addApplication("iperf") do |app| app.setProperty('server', true) end node.net.w0.mode = "master" node.net.w0.type = 'g' node.net.w0.channel = "6" node.net.w0.essid = "TEST1234" node.net.w0.ip = "192.168.0.254" end }}} Several things are happening here: 1. The group name ''AP'' references the node specified in ''property.master''. This group only consists of a single node. 2. ''node.addApplication'' connects the previously defined ''iperf'' application to this node with the specified arguments and values using ''setProperty''. The iperf application is configured as a server. 3. The wireless card properties are set using with the ''node.net.w0'' parameters. Here we set ''node.net.w0.mode'' to ''master'' to configure the wireless card as an access point. Other relevant parameters are also set here as well. * Likewise we use ''defGroup'' again to define a reference name ''client'' for the client node(s). {{{ defGroup('client', property.client) do |node| node.addApplication("iperf") do |app| app.setProperty('client', "192.168.0.254") app.setProperty('time', 20) app.setProperty('interval', 5) end node.net.w0.mode = "managed" node.net.w0.type = 'g' node.net.w0.channel = "6" node.net.w0.essid = "TEST1234" node.net.w0.ip = "192.168.0.%index%" end }}} 1. The group name ''client'' references the node(s) specified in ''property.client''. This group can have multiple nodes. 2. ''node.addApplication'' connects the previously defined ''iperf'' application to the node(s). ''iperf'' is configured as a client connection to the specified ip address. 3. The wireless card properties are set using with the ''node.net.w0'' parameters. Note that we set ''node.net.w0.mode'' to ''managed'' to configure the wireless card as client. Other relevant parameters are also set here as well. Since we can have multiple nodes in a group we specify ''node.net.w0.ip'' with the last byte of the IP address as %index%. In this way each node will have a unique address. * At the end of the script once all the nodes are at the same point and all applications have been initialized, an event is triggered to continue and execute the remaining steps. The 10 second delay before the call to ''startApplications'', this allows time for the clients to establish a !WiFi connection with the access point before continuing. Iperf is started on all the nodes, execution of experiment script is delayed again giving time to collect experiment data. Finally all applications are stopped and the experiment exits out. {{{ onEvent(:ALL_UP_AND_INSTALLED) do |event| info "Wifi Multi Client Iperf Experiment" wait 10 allGroups.startApplications info "All my Applications are started now..." wait property.duration allGroups.stopApplications info "All my Applications are stopped now." Experiment.done end }}} === Executing the Experiment Script === An overview on running experiment scripts on the orbit testbed can be found on the [wiki:Documentation/CGettingStarted Getting Started Page]. In order to run this experiment script, load the ''baseline.ndz'' image onto nodes with !WiFi cards. Check the ''Status Page' in the [https://www.orbit-lab.org/cPanel/controlPanel/start Control Panel] to find nodes with a !WiFi card. {{{ user@console:~$ omf load -i baseline.ndz -t node1-1,node1-2 }}} After the nodes have finished imaging, turn the nodes on. The topology used here is ''system:topo:imaged'' which selected the prior set of node that were successfully imaged. {{{ user@console:~$ omf tell -a on -t system:topo:imaged }}} To run this experiment with 2 clients nodes: {{{ user@console:~$ omf exec test:exp:tutorial:wifi-ap-iperf.rb -- --accesspoint node15-1 --client node16-1,node17-1 --duration 60 }}} The output of this script should be similar to the following: {{{ INFO NodeHandler: OMF Experiment Controller 5.4 (git 3fb37b9) INFO NodeHandler: Reading configuration file /etc/omf-expctl-5.4/services.yaml INFO NodeHandler: Add domain http - http://internal1.orbit-lab.org:5054/ INFO NodeHandler: Add domain http - http://repository1.orbit-lab.org:5054/ INFO NodeHandler: Slice ID: default_slice (default) INFO NodeHandler: Experiment ID: default_slice-2014-10-09t10.15.22.101-04.00 INFO NodeHandler: Message authentication is disabled INFO Experiment: load system:exp:stdlib INFO property.resetDelay: resetDelay = 230 (Fixnum) INFO property.resetTries: resetTries = 1 (Fixnum) INFO Experiment: load system:exp:eventlib INFO Experiment: load system:exp:winlib INFO Experiment: load wifi-ap-iperf.rb INFO property.accesspoint: accesspoint = "node15-1" (String) INFO property.client: client = "node16-1,node17-1" (String) INFO property.duration: duration = 60 (Fixnum) INFO ALL_UP_AND_INSTALLED: Event triggered.
