Abstract Support for hard real-time traffic requires throughput guarantees for packets with timing constraints. The deterministic analysis available for real-time communication has its origin in the area of task scheduling in real-time systems and has been mapped onto the communication context. Mapping uniprocessor scheduling techniques directly on a multichannel network with the possibility of concurrent transmissions, however, introduces pessimism to the analysis. This paper presents an approach of successfully increasing the amount of possible guarantees by analyzing traffic interdependencies. By taking into account those traffic interdependencies and integrating concurrent transmissions into the analysis, the amount of throughput guarantees can be increased considerably as shown in our simulations.
