Easier Analysis of Ethernet Networks With the New Protocol Monitor

For easier analysis of Ethernet networks, the new Protocol Monitor in CANoe and CANalyzer gives you a comprehensive overview of the Ethernet networks and protocols used. At the same time, it shows details of all connection requests, successfully established connections and their end points.


The Challenge

Vehicle Ethernet communications involve a whole stack of protocols: IP, TCP, UDP, SOME/IP, etc. If the communication does not show the expected behavior, the amount of protocols increases the effort for the analysis.

The Solution

With the new Protocol Monitor in CANoe and CANalyzer you can keep an overview. In four windows it shows you the following details clearly:

  • In the central Network Window, you see a graphical summary of the network communication.
  • All endpoints are broken down in a hierarchical structure.
  • There is a tabular overview of all connections.
  • The Detail view provides further information on the currently selected element, such as the timestamp and event counters.

You can customize the Protocol Monitor to meet your individual requirements. Use filters to reduce the view to the desired protocol layers, endpoints, and nodes.

You do not need a separate license for the Protocol Monitor. Since version 15 it is part of the option .Ethernet of CANoe and CANalyzer.
