Mode-Based Scheduling with Fast Mode-Signaling ― A Method for Efficient Usage of Network Time Slots

Tobias Braun, Reinhard Gotzhein, and Thomas Kuhn

Abstract—Today, communication in real-time systems is based on time-triggered or event-triggered protocols, or combinations thereof. Each of these solutions has its benefits and tradeoffs regarding timeliness and bandwidth usage. In this work, we present a new method called mode-based slot scheduling with fast mode-signaling, which can substantially improve bandwidth usage in many scenarios of industrial relevance, while preserving timeliness. With mode-based slot scheduling, a well-controlled amount of dynamic contention for network time slots is possible. Fast mode-signaling is used to reach consensus on the current transmission mode with the highest preference extremely fast and reliably among all network nodes. We present the implementation of our method with TTCAN – a time-triggered protocol in the automotive domain –, and evaluation results.

Index Terms—Mode-based slot scheduling, fast mode-signaling, TDMA, slot assignment, TTCAN.
