ABSTRACT
The introduction of network time protocols such as NTP (at a coarse granularity) and IEEE 1588 (at a fine
granularity) gives a relatively consistent global notion of time that has the potential to significantly change how
we design distributed real-time systems. In [4], we present a programming model called PTIDES (Programming
Temporally Integrated Distributed Embedded Systems) that uses discrete-event (DE) models as programming
specifications for distributed real-time systems and describe an execution model that permits out of order processing
of events without sacrificing determinacy and without requiring backtracking. In this paper, we present an interesting
networked camera application programmed using PTIDES and show how the execution model in [4] can be used
to meet real-time constrains in the system.
