IMMINENCE Mid-Term Review

Recently the mid-term review of the IMMINENCE research project was held at Nokia's site in Madrid, Spain.

Despite a slow start due to COVID restrictions, the overall impression is that the consortium has been able to deliver very good results so far.

The main focus of IMMINENCE is to develop intelligent network management and control functions techniques, for example:

• New mechanisms for future mobile networks: Application Aware Networks, Self-configuration Networks,

• Intelligent network management: Adaptive Management, Autonomous Management,

For TCN, the IMMINENCE research project mainly offers opportunities to evolve its software tool TCN TimeAnalysis for network digital twin modeling and simulation towards 5G support in close collaboration with other parties.

CPAC Systems, together with Time Critical Networks, finish today a joint Thesis Project, aiming to check the feasability of replacing CAN with standard Ethernet.

The purpose of the thesis project was to investigate the possibility of replacing the CAN bus with Ethernet according to the following requirements:

  • Standard off-the-shelf components and software stacks
  • No modification of the network node application software, i.e. messages formatted according to CAN protocols must be transferred by means of Ethernet.

A unique approach to this issue is offered as a result of the work done by Time Critical Networks. Their tool makes it possible to calculate the maximum forwarding time of a frame in an Ethernet network. This tool may make it possible to validate the use of Ethernet for time-critical applications.

CPAC Systems, a company in the Volvo group which develops and manufactures steer-by-wire systems based on the CAN technology, wishes to verify whether Ethernet could now be considered as a solution to complement or replace CAN, thus overcoming limitations of CAN. This verification was the goal of this master thesis project.

Please do contact us for further information about the master thesis project, such as the report.
