    21 === B.1.1 Starting the OML Server (if needed) ===
     21=== 3.1 Starting the OML Server (if needed) ===
    2222For this tutorial we have an OML server running on emmy9.casa.umass.edu, which collects the measurement data in an sqlite3 database and at the end of the experiment it pushes the data to IRODS.
    2323   * Here is how you would have to start an OML server if you wanted to run this on a different machine (OML2.8 is required.)

    156 === B.1.2 Verification of Topology ===
     156=== 3.2 Verification of Topology ===
    157157After establishing the slice on which the experiment will be executed, the experimenter will be most likely
    158158be interested in verifying if the slice has been initiated correctly. In this tutorial, we use an [[http://emmy9.casa.umass.edu/GEC15-GIMI-Tutorial/step1-ping_all.rb OMF experiment script]] that executes pings between neighboring nodes.

    374 === B.1.3 Setup Routing in Experiment Topology ===
     374=== 3.3 Setup Routing in Experiment Topology ===
    375375In more complex topologies routing has to be set up. In our case, this is achieved with the aid of an [[http://emmy9.casa.umass.edu/GEC15-GIMI-Tutorial/step2-routing.rb OMF experiment script]]. The one we use for this tutorial is shown below.

    472 === B.1.4 Verification of Routing ===
     472=== 3.4 Verification of Routing ===
    473473After establishing the routing, we use an [[http://emmy9.casa.umass.edu/GEC15-GIMI-Tutorial/step3-ping_e2e.rb OMF experiment script]] that executes pings between each pair of nodes that contains one hop, to verify the correctness of routing setup.

    661 === B.2 Running Actual Experiment ===
     661== 4 Running Actual Experiment ==
    662662
    663663We will use an [[http://emmy9.casa.umass.edu/GEC15-GIMI-Tutorial/step4-otg_nmetrics.rb OMF experiment script]] to execute oml enabled traffic generator and receiver (otg and otr) to simulate network traffic, and use oml enabled nmetrics to measure the system usage (e.g., CUP, memory) and network interface usage on each of the participated ExoGENI nodes.
