Multi-level Model for Synchronizing Temporal Streams on HLA-Based Distributed Multimedia Applications Using HTSPN

The major issue in distributed multimedia simulation is how to specify and implement synchronization scheme satisfying the QoS applications requirements. This paper suggests the use of a powerful synchronization scheme based on HTSPN between different flows issued from distributed multimedia systems to fulfill these requirements. Such an interpreted model permits powerful analysis techniques for validating the quality of service in computer networks before protocol implementation. Consequently, it allows the specification of both the temporal non-determinism of weakly distributed applications and the temporal variability of the multimedia processing. An example is used to demonstrate the capabilities of this scheme to specify the QoS requirements of simulated applications.
