1. A system arrangement for use in an automobile for low latency and fail-safe command propagation allowing a targeted actuation of each of a plurality of client devices (CD) in real-time, comprising:
an initiator device (I) arranged to generate and initiate commands;
a series of branch devices (BD) communicatively coupled to the initiator device (I) via an Initiator Side Port (ISP), the series of branch devices (BD) being communicatively connected using a transmission medium;
the plurality of client devices (CD) being segmented into a plurality of serial branches each of at least two client devices (CD) along a branch type data line each branch being connected to respectively one branch device (BD), characterized in that each branch device (BD) directly provides commands generated and initiated by the initiator device (I) to respectively a first client device (CD) using a Client Side Port (CSP) of respectively one branch being connected with the branch device (BD) according to a configured mode (M0, M1, M2, . . . , M6), wherein the command is further propagated to the at least one further client device (CD) via the Client Side Port (CSP) of the respective branch device (BD), the mode being configured as a function of the generated command and by a number of received link attention events, wherein the command provides an expiry condition of the mode after which the mode returns to its previous mode.
