Unit tests employing Firefox and Chrome webdrivers capturing both HTTP and HTTPS traffic are included. In the same time, the delivery of critical services from cloud data centers has increased not only the volume of traffic, but also the complexity of transactions. A traffic management plan is usually required to outline the traffic hazards, and to specify the measures needed for traffic control. Traffic classification is an automated process which categorises computer network traffic according to various parameters (for example, based on port number or protocol) into a number of traffic classes. iperf3 session from the client.
