A network configuration for the transmission of communication flows in a real-time communication network, wherein the network comprises components, which are connected by links, wherein an arrangement of the components and links of the network is described by a network topology, wherein said components of the network communicate via a defined set of communication flows, wherein the method comprises a first, a second, and a third module, as well as a first and a second feedback loop, wherein in a first step the first module computes, based on said network topology and said set of communication constraints, one route for each communication flow of said set of communication flows, and wherein, in a second step, after the first step has finished, said second module, computes a time-triggered schedule for the communication of said TT flows, so that one or more of the constraints related to said TT flows are fulfilled.

Method to configure real-time communications in a network with time-triggered and rate-constrained traffic

A method for generating a schedule for the transmission of time-triggered, TT, messages in a network, wherein said network communicates TT messages according to said schedule and based on a global, network-wide time, wherein said network communicates rate-constrained, RC messages, wherein for each of said RC messages real-time requirements are provided, wherein the method comprises: Step 1: setting the transmission time of all TT messages which are communicated in the network, and Step 2: executing a search function to find a set of TT transmission times so that the real-time requirements of all RC messages are fulfilled, and when all real-time requirements or at least real-time requirements for defined RC messages are fulfilled, generating in Step 3: the schedule based on the transmission times retrieved in Step 2, or executing Step 2 again when not all real-time requirements or not all real-time requirements for the defined RC messages are fulfilled.
