Time Sensitive Networking (TSN) working group has added a set of mechanisms to Ethernet in order to provide a real-time network. In particular , the output port scheduling based on Credit-Based Shaper (CBS) has been enhanced with a time driven Gate Control List (GCL). In this paper, we show that the interactions between both mechanisms can lead to unexpected behaviours, creating bursts of low priority flows. We then propose a small modification of the rules whose aim is to reduce these bursts.
