    55In this example experiment, you will configure and run an OpenFlow experiment. In this experiment we are going to deflect service requests from one server to another. We are going to use:

    30 omni.py createsliver -a pg-utah <slicename> <rspec_url>
     28  i. '''Create all the slivers''' using the rspecs from the URL given in your paper slip:
     29  {{{
     30omni.py createsliver -a <AM_nickname> <slicename> <rspec_url>

    3232  i. '''Check the status of your sliver'''
    3333  {{{
    34 omni.py sliverstatus -a pg-utah <slicename>
     34omni.py sliverstatus -a <AM_nickname> <slicename>

    3838While you wait for your sliver to become ready, we will see how we can automate the installation of our experiment with install scripts.
    3939In this experiment we are going to use software routers in order to write our own forwarding scheme. This means that in any experiment we are going to run we want the basic installation of the software router to always be present. The configuration might change from run to run, but the software should always be installed. The software to be installed, and the scripts to be executed at boot time, are defined in the rspecs. Follow these steps to locate your install script and identify the different parts.
    40   i. Download your rspec
     40  i. Download your rspec you used in the `pg-utah` AM.
    4141  {{{
    4242   cd /tmp
     
    5353  i. Locate the script and open it. Can you identify the different parts?

    55 == 3. Configure your routers ==
    56 Once our sliver is ready we will go ahead and configure our click routers. In this example we have 4 routers, so instead of logging into each one of them and configuring it, we are going to use remote execution and configure them from our VM.
     55== 3. Configure your hosts ==
     56Once our slivers iare ready we will go ahead and configure our myPlc hosts. Instead of logging into each host to install the necessary softwarem we are going to use remote execution and install it from our VM.
