Develop the following FlexRay™ cluster: The cluster consists of the five nodes A, B, C, D, and E. All nodes should be connected via two channels.

The cluster uses a bus topology. The nodes A, B, and C are executing a safety critical task, and therefore their bus requests should be guaranteed at the time of 20 macroticks. The following is expected from you:

Download the levi FlexRay simulator [495]. Unpack the ZIP file and install!

Start the training module by executing the file leviFRP.jar.

Design the described FlexRay cluster within the training module.

Configure the communication cycle such that the nodes A, B, and C have a guaranteed bus access within a maximal delay of 20 macroticks. The nodes D and E should use only the dynamic segment.

Configure the node bus requests. The node A sends a message every cycle.

The nodes B and C send a message every second cycle. The node D sends a message of the length of 2 minislots every cycle, and the node E sends every second cycle a message of the length of 2 minislots.

Start the visualization and check if the bus requests of the nodes A, B, and C are guaranteed.

Swap the positions of nodes D and E in the dynamic segment. What is the resulting behavior?
