+
+One client and one server are created using nova. Then a SF is created using tacker.
+A service chain which routes the traffic through this SF will be created as well.
+After that the chain is deleted and re-created.
+
+vxlan_tool is started in the SF and HTTP traffic is sent from the client to the server.
+If it works, the vxlan_tool is modified to block HTTP traffic.
+It is tried again and it should fail because packets are dropped.
