Embodiment Construction

[0050] In the following description of the embodiments and in the drawings, identical or similar elements have the same reference numerals in the drawings.

[0051] refer to figure 1 , firstly, a configuration method of an Ethernet switch conforming to the prior art will be described.

[0052] The Ethernet switch 103 shown on FIG. 1 is integrated in a motor vehicle ( figure 1 not shown above) in the device 101 of the vehicle network. The device 101 also integrates a computer 102 with at least one processor and memory and communicating directly with a switch 103 . In the example shown, the Ethernet switch is equipped with three ports 104 which allow the Ethernet switch, in normal use, to transmit data from a source device towards at least one destination device. A person skilled in the art realizes that in practice the number of ports of such a switch is not limited to three and is at least more than two. Typically, Ethernet switches on the market include eight ports. Like...

Abstract

What is disclosed is a method for configuring an Ethernet switch (303) of an on-board network (206) of a motor vehicle (205). The method is based on using a dedicated software module (302), stored in the memory of the computer (301) of a device of the network (201) into which the computer is integrated, which makes it possible to interpret generic commands that are intended to configure an Ethernet switch of any kind, so as to be able to generate (402) specific configuration commands for the Ethernet switch in question.

Description

technical field [0001] The present invention relates generally to the field of on-board networks in motor vehicles, and more particularly to the testing of on-board local area networks in motor vehicles. [0002] The invention relates to a method for configuring an Ethernet switch of such a vehicle network, which is implemented for testing the network. Background technique [0003] The integration of Ethernet technology into the on-board network of a motor vehicle can simultaneously facilitate a high degree of modularity of the network and a high data transmission rate. An Ethernet network, especially an Ethernet network operating in switching mode on the IP protocol ("Internet Protocol" in English), is a network with a star topology. The star topology is organized around an Ethernet switch ("Ethernet Switch" in English), which interconnects all the devices of the vehicle Ethernet network. In particular, the transmission of a data frame in said network from a source device...
