Webmation of the schedulability of these ﬂows, i.e., the ability to fulﬁl all their timing constraints, is a long-standing concern in industrial communications. In this paper, we recall and compare the performance of two demand-based schedulability tests discussed in [5], which are based on the so-called demand-bound function (DBF) [6], [7],
