1. A data transmission system comprising a total network that comprises a plurality of sub-networks, wherein:
- a first sub-network among said sub-networks comprises a first star distributor and a plurality of first peripheral units respectively connected by a corresponding plurality of individual physical data channels to said first star distributor;
each said sub-network is implemented in a link layer (layer TWO) of an open systems interconnection OSI reference model;
said first star distributor comprises a first switch implemented in said link layer (layer TWO) of said OSI reference model;
said first star distributor is connected to said first peripheral units respectively via said individual physical data channels so as to form a cross-distributor for all of said first peripheral units connected to said first star distributor, so that each of said first peripheral units is able to communicate directly with each other one of said first peripheral units via said cross-distributor using exclusively media access control MAC addresses on said link layer (layer TWO) of said OSI reference model.

Abstract
A data transmission system for aircraft is formed by a global transmission network that includes at least one subnet with at least one star distributor. At least one peripheral unit is connected to the star distributor. The star distributor is so wired or circuit connected that each subnet forms a cross-distributor for a respective peripheral unit connected to the subnet.

17. A data transmission system comprising a total network that comprises a plurality of interconnected sub-networks, wherein:
-
a first sub-network among said sub-networks comprises a first star distributor and a plurality of first peripheral units respectively connected by a corresponding plurality of individual physical data channels to said first star distributor;
a second sub-network among said sub-networks comprises a converter;
said data transmission system further comprises an aircraft-specific data bus system that is implemented according to an ARINC standard and that is connected to said converter; and
said data transmission system further comprises a general data bus system that is not implemented according to an ARINC standard and that is connected to said converter.
