How to run the security experiments

There are a number of Python and bash scripts needed to run the security experiments.

1. config.py contains several important global variables to be imported to other Python's scripts:

   • NODES: the list of strings representing the server IP addresses.
   • partition_cmd: use to specify the script that simulates partition attacks.
   • TIMEOUT: how long the partition lasts

2. partition.py: implements the function partition(node_list, time_out) that partitions the nodes in the given node_list in half, and keeps the partition for time_out seconds. It basically invokes the following scripts with different parameters:

    ` partition.sh <node_i> <node_j> <time_out>`
   

3. partition.sh <node_i> <node_j> <time_out>: drops TCP connection between the 2 nodes for the given time_out seconds.

4. run-bench-security.sh <#nodes> <#threads> <#clients> <#req rate>: works the same way as run-bench.sh, except that it invokes partition.py at 100th second.

5. exps.py: contains the main script for launching the experiments:

    ` python exps.py -security`
