Synchronized real-time networks

Christof Brandauer, Peter Dorfinger, Vinod Kone (2005): Synchronized real-time networks In: Proceedings of the Work-in-progress session of the 27th IEEE Real-Time Systems Symposium (RTSS 2005), Miami, Florida, December 5-8, 2005

This paper discusses an approach for coupling local realtime networks over an IP core network. The proposed service class provides deterministic guarantees on delay and jitter. To
realize this, synchronized transmission schedules are employed in the access areas of the network. The schedule precludes resource contention among the flows and enables a conflict free transmission at the IP layer. Mathematical models for the request admission probability are derived for simple allocation schemes. It is shown that variable delay allocation schemes can significantly increase the admission probability. Finally, a prototype testbed is described.
