In this increasingly connected world the spread of the Internet is, in fact, revolutionizing the way of conceiving applications that gradually tend to migrate to the network to be accessible wherever you are. The design must be done with a different point of view taking into account that these applications must respond to requests from anywhere in the world and not just from local networks. The basic problem is that an app designed to operate over a WAN is actually developed within a Local Area Network (LAN). In this way it is difficult to objectively assess its performance given the fact that a local network has very different characteristics from those of a Wide Area Network (WAN) in terms of bandwidth, latency, packet loss, etc.. Often the loss of performance which can be observed in the transition from the development environment, in which tests are run, to that of production is to be attributed in a decisive manner to the type of connections. It becomes essential to have a tool by which to try the possible scenarios. In the course of this technical report we will see how to install and use a software to simulate the use of an application-level WAN.
