A GroupVPN controller for structured peer-to-peer virtual private networks

Scale Test for the IPOP Structured P2P GroupVPN Controller

Description

This project is composed of scripts for automating the preparation and simulation of a testbed for scalable testing of the IPOP network using structured-p2p-gvpn-controller, which has been pushed upstream [1].

[2] http://ipop-project.org/ or https://github.com/ipop-project

Usage

Obtaining the source code

git clone https://github.com/ipop-project/controllers.git
cd controllers/; git checkout devel; cd -

git clone https://github.com/ssabogal/ipop-gvpn-scale-test.git
cd ipop-gvpn-scale-test/
mv ../controllers/controller scale/node/ipop/

Note: A precompiled binary for IPOP-Tincan is available in scale/node/ipop. The latest IPOP-Tincan can be obtained by downloading the latest archive from the releases or by building from source [2].

Preparing physical nodes (using CloudLab)

Pre-defined profiles

Use any of the following pre-defined profiles:

IPOP_SCALE_TEST_1_VIVID
IPOP_SCALE_TEST_2_VIVID
IPOP_SCALE_TEST_5_VIVID

Create a profile

Create a profile, with at least one node and each node containing the following properties:

• Node Type raw-pc

• Hardware Type C220M4

• Disk Image Other... with URN urn:publicid:IDN+emulab.net+image+emulab-ops:UBUNTU15-04-64-STD

• Check the Publicly Routable IP option

Create an experiment

Note: ensure that the host's SSH keys are applied to the CloudLab account.

Instantiate this profile as to create an experiment.

Using the automated test script

Open the List View tab to view the connections. Copy the connections (of the form <username>@<hostname>) into scale/scale.cfg as NODE, SERVER, or FORWARDER. Also specify the SIZE (the number of IPOP instances)

Run the bash script: bash scale/scale.bash

Enter the following commands (see the README.md in scale/ for information about what these commands do):

accept    # enter 'yes' if prompted
install
init
source
config <num_successors> <num_chords> <num_on_demand> <num_inbound> <ttl_link_initial> <ttl_link_pulse> <ttl_chord> <ttl_on_demand> <threshold_on_demand>
run all

Example: config 2 3 2 8 60 30 180 60 128 defines the BaseTopologyManager to support:

• about 2 successors
• up to 3 chords
• up to 2 on-demand links
• about 8 in-bound links
• initializing links have a time-to-live of 60 seconds before they are trimmed
• established links have a time-to-live of 30 seconds before they are trimmed
• chords have a time-to-live of 180 seconds before they may be replaced
• on-demand links have a time-to-live of 60 seconds before they undergoes a threshold test
• on-demand links have a threshold of 128 transmitted bytes per second before they are trimmed

To view the IPOP network using the available visualizer, enter forward <port> within the bash script.

Using the visualizer:

Note: the visualizer depends on TKinter, use pacman -S tk (in Archlinux) or apt-get install python3-tk (in Ubuntu/Debian).

In scale.bash:

forward <forwarder port>

In a separate terminal:

python3 scale/visualizer.py tcp <forwarder ipv4> <forwarder port> <SIZE> <GUI window size (length)>
