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. … … 372 372 ---- 373 373 374 === B.1.3 Setup Routing in Experiment Topology ===374 === 3.3 Setup Routing in Experiment Topology === 375 375 In 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. 376 376 … … 470 470 ---- 471 471 472 === B.1.4 Verification of Routing ===472 === 3.4 Verification of Routing === 473 473 After 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. 474 474 … … 659 659 ---- 660 660 661 == = B.2 Running Actual Experiment ===661 == 4 Running Actual Experiment == 662 662 663 663 We 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. 664 664 665 665 [[Image(otg_nmetrics.png)]] 666 667 666 668 667 … … 818 817 [[BR]] 819 818 820 == C.1!LabWiki ==819 == 5 !LabWiki == 821 820 822 821 Labwiki is a tool which provides a user-friendly interface to visualize your experiment.

In this column you will also be able to edit your experiment script.[[BR]] 850 849 … … 856 855 Next, click and drag the icon at the top left corner over to the right column Execute.[[BR]] 857 856 858 === C.1.3 Execute ===857 === 5.3 Execute === 859 858 860 859 Here, you can start your experiment and Visualise it.
