How to test the P4 OPP application?
##P4 download
Download a clean Mininet 2.2.1 VM on Ubuntu 14.04 (64 bit) at this link.
You need to clone two p4lang Github repositories:
cd ~
git clone https://github.com/p4lang/behavioral-model.git bmv2
git clone https://github.com/p4lang/p4c-bm.git p4c-bmv2
Install the following Python packages:
sudo apt-get update && sudo apt-get install python-pip
sudo pip install scapy thrift networkx
Each of these repositories comes with dependencies:
cd ~/p4c-bmv2
sudo pip install -r requirements.txt
cd ~/bmv2
./install_deps.sh
Do not forget to build the code once all the dependencies have been installed:
cd ~/bmv2
./autogen.sh
./configure
make
###Test application
The test application mantains a packet counter for each IP_SRC,IP_DST pair in the register R0. Condition 0 is R0>=4.
The XFSM table can be found in ~/OPP.p4/OPP_test_app/p4src/test_app.p4
$ cd ~/OPP.p4/OPP_test_app
$ ./run_demo.sh
mininet> h1 ping h2
The switch should drop all the packets from the 5-th on
