Claim:
1. A switched data transmission system for use in avionics applications, comprising: a plurality of switches; and a plurality of transmitters transmitting discrete messages over a transmission network, each of the transmitters is connected to a switch, wherein the switches are connected to each other by data transmission links forming a physical topology of a loop network, wherein each message is associated with information regarding data flow priority in the network comprising of functional priority information, wherein each message is also associated with information regarding temporal priority of data flow in the network, wherein the switches of the network share a common temporal reference framework, wherein the common reference framework allows the managing of the temporal priority, wherein the transmission of each message having a functional priority level superior to the functional priority level of a second message takes precedence over the transmission of the second message regardless of the time priority levels associated with the two messages, wherein the switches are adapted to ensure that the newest messages are prioritized to take precedence over others, and wherein each of the switches is configured to decrement the temporal priority of each message in an output port of the switch during transmission of the message.
