This paper introduces the concept of switched FlexRay networks and proposes two algorithms to schedule data communication for this new type of network. Switched FlexRay networks use an intelligent star coupler, called a switch, to temporarily decouple network branches, thereby increasing the effective network bandwidth. Although scheduling for basic FlexRay networks is not new, prior work in this domain does not utilize the branch parallelism that is available when a FlexRay switch is used. In addition to the novel exploitation of branch parallelism, the scheduling algorithms proposed in this paper also support all slot multiplexing options as defined in the FlexRay v3.0 protocol specification.
