• Setup a Mininet environment on a VM (see instructions). If you're using Windows on your local machine, consider working with PuTTY & Xming in order to enable xterm usage in Mininet
• Setup HPE VAN SDN Controller on a separated VM (see videos). Note: use Ubuntu 14.04.
• For both VMs, in the Network settings, set Adapter 1 as NAT and Adapter 2 as Host-only Adapter.

1. Bring up the VMs of Mininet and the SDN controller.
2. Clone this project to the Mininet VM and browse to the iot-zipris directory.
3. Bring up Mininet with the project's topology, OF 1.3 switches and the HPE VAN SDN Controller:

sudo mn --custom exercises/iot_sec_host/infrastructure/iot-zipris-topo.py --topo ziprisTopo --controller=remote,ip=<SDN Controller IP> --switch ovsk,protocols=OpenFlow13 --nat

You can execute in the Mininet terminal the command pingall to make sure that the topology established successfully.
Note: for simulating a realistic environment, post the following requests manually to the SDN controller:

1. Generate a token for the controller using the request in exercises/iot_sec_host/infrastructure/payloads/request_auth.json
2. Enable port-mirroring in the main router, so traffic from the home network will be mirrored to the 'security SmartNIC': exercises/iot_sec_host/infrastructure/payloads/request_router_port_mirroring.json
3. Enable DSCP marking on the home network switches: exercises/iot_sec_host/infrastructure/payloads/request_switch_mark_iot_dscp.json

The project's topology enables the following hosts:

1. h1 - the security SmartNIC of the ISP
2. h2 - an IoT device in the home network #1
3. h4 - a non-IoT device in the home network #1
4. h5 - a valid destination of h2
5. h6 - an invalid destination of h2
6. h7 - an IoT device in the home network #2
7. h8 - a valid destination of h7
8. h9 - an invalid destination of h7

After bringing up the project's Mininet topology, use xterm <host name> in order to control the hosts.
On h1, browse iot-zipris/exercises/iot_sec_host and execute python security_switch/listener.py h1 in order to monitor the traffic to h1 and enable packets classification solution.
On the rest of the hosts, browse iot-zipris/exercises/iot_sec_host and execute python receive_qos.py <host name> in order to monitor the traffic.
Now use Mininet terminal in order to send traffic between the hosts and monitor the network's behavior.
