Method for transmitting messages in a computer network, and computer network

Abstract

The invention relates to a method for transmitting messages in a computer network, and to a computer network of this type. The computer network comprises computing nodes (-), said computing nodes (-) being interconnected via at least one star coupler () and/or at least one multi-hop network (), wherein each computing node (-) is connected via at least one communication line () to the at least one star coupler () and/or the at least one multi-hop network (), and wherein the computing nodes (-) exchange Ethernet messages with one another and with the at least one star coupler () and/or the at least one multi-hop network (). A set of two or more components are directly connected to one another in each case by two or more communication lines (), wherein each component in the set is either a computing node (-) or a star coupler (), and sending components in the set of components send to at least two of the two or more communication lines () at least a proportion of the Ethernet messages that are to be sent, and receiving components in the set of components then accept and/or forward at least a proportion of the Ethernet messages received via the two or more communication lines () only if at least two identical messages are received via at least two different communication lines.
