Abstract

The present invention relates to a star coupler connected to a plurality of nodes in a network using a slot-based time-triggered protocol. The invention also relates to a network comprising a cluster with at least one node. Furthermore, the invention relates to a method of communicating between nodes in a network using a time-triggered protocol. In order to provide a star coupler capable of increasing bandwidth and communicating with low transmission delay, a star coupler (11) is proposed comprising a switch (22) having a plurality of input branches and an output branch, wherein a switch controller for controlling the switch (22) is provided; the coupler also includes means (14, 15) for deriving relevant information about the timing of the protocol, which information is used to set the Data is selectively transmitted to at least one predetermined output.

Description

technical field

[0001] The present invention relates to a star coupler connected to a plurality of nodes in a network using a slot-based time-triggered protocol. The invention also relates to a network comprising a cluster, wherein the cluster comprises at least one node. Furthermore, the invention relates to a method of communicating between nodes in a network using a time-triggered protocol. Background technique

[0002] Reliable automated communication networks generally rely on time-triggered communication protocols such as TTP / C or FlexRay based on propagation methods according to predetermined TDMA mechanisms. A time-triggered protocol is proposed for use in distributed real-time communication systems eg in the automotive industry. Such a communication protocol is described in "FlexRay - A Communication System for advanced automated Control Systems" in SEAworld congress 2001.

[0003] In these systems, the medium access protocol is based on a timetriggered multiplex...
