Abstract

The present disclosure relates to a module for a first Ethernet node of a group of Ethernet nodes, the module comprising a media access control, MAC, interface, a physical coding sublayer, PCS, interface, and a priority manager, PM, interface, wherein the module is configured to receive and/or transmit sequences of a cycle over the interfaces, wherein the cycle comprises a start sequence, a series of multiple priority sequences, an announcement sequence, and a data sequence, wherein the start sequence consists of a sequence of a predefined start symbol and a predefined advertisement symbol, wherein each priority sequence consists of a sequence of a predefined commit symbol and a dedicated priority symbol, which is assigned to the respective priority sequence and indicates a priority of an Ethernet frame ready to be sent by one of the group of Ethernet nodes, wherein the announcement sequence consists of a sequence of the start symbol, a predefined commit symbol and a winner node symbol indicating one of the Ethernet nodes being ready to send the Ethernet frame having the highest priority, and wherein the data sequence comprises the Ethernet frame having the highest priority. The present disclosure also relates to an Ethernet node including the module and a communication system including several Ethernet nodes.
