Scenarios

The purpose of scenarios is to reduce the effort required to configure EdgeLab

Outline

The scenarios directory contains five custom scenarios. Within each of the scenarios directories

• 12e-t2-s0
• 12e-t2-s1
• 2e-t0-s1
• 6e-t1-s1
• 6e-t2-s1

There should be a config.aal and a run_scenario.sh. Note: in 6e-t2-s1 the run_scenario.sh script is in 6e-t1-s1.

The config.aal (agent animation list) contains a set of configuration settings used by magi.

The run_scenario.sh script will then call magi to start and stop certain modules:

• click
• general_viz
• http
• iperf
• mgen
• rtp
• simple_reorder
• targeted_loss
• tcpdump1

on the nodes specified in the config.aal file. The actions given in run_scenario.sh will use the action by the same name in the AALS/ directory (these are generally named start.aal and stop.aal for starting and stopping services. The agents_and_groups.aal and scenario_functions.sh are middleware that assists in allowing for easy to create scenarios.

There is also the modify_click/ directory which contains a framework for modifying click in an easy manner. The README gives additional details on using modify_click.

How to use Scenarios

1. Verify that MAGI is running on all nodes:
   running: magi_status.py -e experiment_id -p project_id
   should return: 01-22 10:07:20.908 root INFO Received reply back from all the required nodes
2. ssh to your control node: (control.experiment.project.isi.deterlab.net)
3. cd /proj/edgect/scenarios/{SCENARIO}
4. sudo ./run_scenario.sh
