This real-time version of Milner’s scheduler schedules N processes arranged in a ring of nodes. Each nodes receives a start signal from the previous node to start the job and in the mean time forward the token to the next node within a given time interval. To this purpose, a node N[i] has three ports rec[i], w[i], and rec[i+1] (modulo N). the model of a node is displayed in the figure below:

This example is studied here. We can check in PyECDAR the robust consistency of the system composed by different number of nodes. The results are displayed in the table below:
