Synchronized Access Networks∗

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. A mathematical model for the request admission probability is derived for a simple allocation scheme. First simulation results show that this probability can be increased significantly with alternative allocation algorithms.
