Sensor

A sensor in the application is a device that has the capability to create a Data Flow, stored in a capture file. Thus, the Sensor can be the source of a Stream.

The sensor can inject packets into a virtual Ethernet network by reading Ethernet frames with high-precision time stamps from a capture file. In the delivery, it is provided such a capture file with a recording of an automotive Ethernet best effort camera.

Please note that when a PCAP file is to be examined using Packet Counters in a network digital twin model of a physical network, the file should be associated with the port of a Sensor node that corresponds to the device port in the physical network in which the packets were captured. It is also important that the network digital twin model mirrors the physical network topology and specifically that the MAC addresses assigned to Host and Sensor ports are the same as the source MAC addresses encountered in the captured packets read from the PCAP file.

To add a new Sensor to your system model, click the Sensor button in the Toolbar.

This will open the Sensor dialog:

Sensor

The following actions are available for existing Sensors - right-click on a Sensor in the topology or the tree view:

     
Edit Opens the Sensor dialog in edit mode.
Delete Removes the Sensor from the topology.
Note! this will affect for example streams where this Sensor is used.
