Abstract
The invention relates to a method for transmitting a target data frame (fA) on a path comprising at least one router (R) that has input ports (P1, P2, P3), at least one output port (PS) and an arbitration unit (UA) configured so as to select a data frame from a plurality of data frames each coming from a different input port and competing for transmission by one and the same output port. The method comprises specifying, for each of the access ports of the router, data frames (fB, fC) competing with the target data frame for transmission by a target output port of the router. An end-to-end transmission time of the target data frame on the path is then measured while the arbitration unit selects the competing data frame (fB) before the target data frame (fA) for transmission by the target output port (PS).
