A proposal for flexible, real-time and consistent multicast in FTT/HaRTES Switched Ethernet

Hard Real-Time Ethernet Switching (HaRTES) is an implementation of the Flexible Time Triggered (FTT) communication paradigm over Switched Ethernet, which intends to provide hard real-time communication in a flexible manner. This paper presents a first proposal for enhancing HaRTES with a service of total order multicast for synchronous messages. This service uses the centralized online scheduling service of FTT in order to reduce complexity and bandwidth utilization.
