This is the official repository of the P4I/O prototype.

P4I/O is an intent-based networking platform to generate and run network functionality on P4 switches. This repository contains a prototype-grade software version of the P4I/O platform. The idea behind this prototype is described in detail in the P4I/O paper.

Please cite the original paper instead if you would like to give credit for or refer to the software:

The system was developed on Ubuntu 16.04 LTS, so please use it for optimum compatibility. Before you can run the prototype, you need to build and install the required software. Please use the script available in the utils/ directory:

sudo utils/bootstrap.sh

The script should install all of the required dependencies. It was last tested on 17-Apr-2019 on a fresh installation of Ubuntu 16.04 LTS.

You can run the software using the following command:

cd src
make

# you will get mininet console here..

# to stop mininet and clean the build dirs after exit
# mininet> exit

make clean

To change the intent while the virtual switch is running, you can run the intent_listener.py program:

cd src
sudo python intent_listener.py

From another session, you can then send an intent via a HTTP POST request with the data in the data. For example (if you use curl):

curl -d "@intent.txt" -X POST http://localhost:5050/intent

Content example of intent.txt:

import drop_heavy_hitters

define intent dropHeavyHitters:
  to     any
  for    traffic('any')
  apply  drop_heavy_hitters
  with   threshold('more',50)

Support is not available for this software. If you have any question, you can open an issue in this repository or mail to [email protected]. Please note that, however, an answer is not guaranteed.
