<h1>Simulation Mode</h1>
|
|
|
|
<h2> Using and Installing Software </h2>
|
|
<p> Performing a click on a computer/notebook the virtual desktop of the
|
|
component is opened as a new window. Using the icon at the upper left corner of
|
|
this window opens another internal window to select the installed software at
|
|
the computer, i.e. to install and remove programmes.
|
|

|
|
<p> The graphical user interfaces of these programmes are opened by selecting the
|
|
icons at the virtual desktop. The behaviour of these programmes does not depend on
|
|
whether the graphical user interface, i.e. the internal window, is opened or not. </p>
|
|
|
|
<h2> Looking at the IP Configuration </h2>
|
|
<p> It is possible to have a look at the IP configuration by selecting the icon in the
|
|
lower right corner of the desktop window.

|
|
|
|
<h2> Observing Data Exchange </h2>
|
|
<p> The time delay during the simulation of the data exchange can be changed by
|
|
the slider at the upper panel of the main window. </p>
|
|
<p> Every data unit which is sent or received by a computer is logged and can be displayed.
|
|
Use the context menu to open the window which displays the window with the data units. </p>
|
|
<p> In the table with the data units every protocol data unit is represented by one
|
|
or more rows. The protocol data units of the four layers of the Internet layer model are
|
|
shown. </p>
|
|
|
|
<h2> Configuring the Firewall of the Router </h2>
|
|
<p>
|
|
To configure the firewall every router provides a web interface. Therefore, to configure
|
|
the firewall in the simulation mode it is necessary to start the webbrowser at a
|
|
connected computer and to start with an IP address of the router to address its
|
|
web-server. </p>
|
|
<p> The configuration and activation or deactivation of the firewall is done by
|
|
a web formular. Besides there is the possibility to look at the logging data of
|
|
the firewall. </p>
|
|
|
|
<h2> State of the Switch </h2>
|
|
<p> The switch stores the MAC addresses of incoming protocol data units in connection
|
|
with the port of the physical connection. This data is stored in the Source Address Table
|
|
(SAT). It is possible to show this table by a click on the switch. </p>
|
|
|
|
<h2> Switch Application Mode </h2>
|
|
<p>
|
|
The infrastructure of the virtual computer network and the IP configuration of the
|
|
components can be modified in the design mode. Switch to this mode using the icon at
|
|
the upper panel.
