A Network Controller Interface for a Time-Triggered Protocol
Andreas Krüger, Hermann Kopetz · SAE technical papers on CD-ROM/SAE technical paper series · 1995
A time triggered communication protocol that derives its control information e g when to send a message from the progression of time o ers unique features that meet the stringent demands of automotive class C con trol applications The interface to a dedicated network controller executing such a protocol can be viewed as a system wide interface and is thus a perfect starting point for the system s decomposition into autonomous non interfering subsystems This paper presents such a network controller interface that allows applications to transparently access the services of the underlying communication protocol The interface is designed as a data sharing interface i e the ow of control informa tion across the interface is restricted to the necessary minimum With this the chance of control error prop agation is reduced considerably The interface acts as a temporal rewall facilitating independent subsystem development and validation
