Each node computer has an Ethernet controller, which by way of a data line is directly connected to a port of a TTE star coupler, said port being uniquely associated with the node computer. A plurality of TTE star couplers are connected among each other by way of one or more data lines to form a TTE network. A TTE message scheduler dynamically calculates the conflict-free schedules for a number of time-controlled messages and signs the schedule provided for each node with a secret part of a public-key signature before it transmits said schedule to the corresponding node computer. Each node computer integrates the signed periodic schedule, which is transmitted to the node computer in the form of a TTE message header of an ETE message, into each dynamically calculated TTE message. The TTE star couplers check whether each dynamically calculated TTE message contains an authentically signed schedule."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for secure dynamic bandwidth allocation in a TT ethernet","description":"A communication method for transmitting TT Ethernet messages is a distributed real-time system, including a plurality of node computers.
