Modeling and analyzing precision time protocol — Application to prototyping distributed embedded systems

Abstract

Prototyping distributed embedded system can be seen as a collection of many requirements covering many domains. System designers and developers need to describe both functional and non-functional requirements. Building distributed systems is a very tedious task since the application has to be verifiable and analyzable. Architecture Analysis and Design Language (AADL) provides adequate syntax and semantics to express and support distributed embedded systems. This paper studies a general methodology for prototyping distributed applications using the Precision Time Protocol (PTP) for building and translating AADL systems into a distributed application using network communication protocol. This allows simulation of systems specified in AADL to fully assess system viability, to refine and to correct the behavior of the system using the BIP (Behavior Interaction Priority) toolset.
