1. Network for data transmission, comprising:
- a plurality of sub-networks for transmitting data in data frames, in which each sub-network has at least two subscribers;
at least one gateway connecting each sub-network to at least one other sub-network for transmission of data between the sub-networks;
wherein at least one first sub-network is configured for at least one of simultaneous addressing of data frames to a plurality of subscribers (broadcast or multicast), and random addressing of single data frames or parts of data frames, and this at least one first sub-network is furthermore adapted for synchronous transmission of synchronous data or control data, and normal package data; and
for real-time transmission with deterministic transmission times between sub-networks by an exchange of time synchronization signals and a synchronization of at least one first sub-network and at least one other sub-network with these signals, a transmission of individual data frames between the respective sub-networks is effected with a defined timing relationship between the sub-networks.

Abstract
A network for data transmission comprises a plurality of sub-networks for transmitting data in data frames. The sub-networks have different transmission rates and are connected to each other via at least one gateway. The transmission of the data frames is effected with a defined timing relationship between the sub-networks.
