Installation

Install docker if you don't already have it.

Clone the repository to local

git clone https://github.com/DINGDAMU/Network-wide-heavy-hitter-detection

 cd Network-wide-heavy-hitter-detection

If you want, put the p4app script somewhere in your path. For example:
```
cp p4app /usr/local/bin
```
I have already modified the default docker image to dingdamu/p4app-ddos:nwhhd, so p4app script can be used directly.
```
./p4app run nwhhd.p4app 
```
After this step you'll see the terminal of mininet
Open a new terminal
```
 cd nwhhd.p4app 
```
Enter the terminal of Docker
```
 bash terminal.sh 
```

Activate interface veth0 to monitor all packets in the Network

 ip link add name veth0 type veth peer name veth1
 ip link set dev veth0 up
 ip link set dev veth1 up

Start controller in Docker
```
 sudo python3 controller.py
```
Go back to mininet terminal and run following command within 5s (5s is the time interval) We set 10 time intervals in this case
```
pingall
```

11. Check the results of controller
