Abstract :
This paper presents the different tradeoff in implementing IEEE1588 on top of HSR by evaluating the different alternatives offered by the time synchronization protocol. The evaluation is based on the accuracy of the achieved synchronization, its complexity and its conformance to the HSR protocol. While HSR and IEEE1588 seem to be promising candidates for substation automation communications, their simultaneous usage raises interesting challenges as they are based on opposite assumption.
