1. A method for establishing deterministic communication routes in a large computer network, wherein all affected end systems and switches of the computer network have a global time, the method comprising steps of:
generating a deterministic communication route on the basis of an existing communication route between two or more end systems of the computer network; testing, by a time-triggered connection manager (TTCM) of an end system, feasibility of the deterministic communication route with respect to a respective network switch in a request phase, by sending requests to each network switch along the existing communication route; reserving, by the time-triggered connection manager (TTCM) of an end system, the deterministic communication route in a reservation phase by sending a reservation message to each network switch of the existing communication route up to a reservation commitment time (KZPT); and confirming, by the time-triggered connection manager (TTCM) of the end system, this deterministic communication route in an accept phase by sending an accept message to the network switches of the existing communication route before the KZPT. |
