- each network management function can now be managed by each of the organs (or nodes) Ethernet, and can even be divided between several Ethernet devices.
- the management device according to the invention may include other features that can be taken separately or in combination, and in particular:
- the management protocol for transmitting to the transport layer of its Ethernet element a concatenated frame comprising at least two frames of management data each comprising a message that has been generated by a service provided by its Ethernet element, intended for at least one other Ethernet element, placed one after the other, and encapsulated between a UDP header of a UDP protocol of the transport layer and a checksum field of a layer of network access of the TCP / IP model;

- FIG. 3 schematically illustrates an example of a concatenated frame comprising three frames of management data compliant with the management protocol of the invention and encapsulated.
- the object of the invention is in particular to propose a management device DG intended to equip an Ethernet device Oj to be coupled to an Ethernet / IP type TCP / IP-based network communication network.
- the layer structure of the TCP / IP model includes a first network access layer using the MAC 802.3 protocol, a second network layer using the IP, ARP, ICMP and IGMP protocols, a third transport layer using the TCP and UDP protocols (User Datagram Protocol), and a fourth application layer allowing services provided by the organs (or nodes) Ethernet Oj to access the communication network RC.
- the protocols used in this application layer basically depend on the services that are offered by Oj Ethernet organs (or nodes).
- the RC communication network is intended to be installed in a vehicle V automobile, such as a car.
- the invention is not limited to this application. It concerns any system, installation or apparatus that may include at least one Ethernet / 1P communication network suitable for the bidirectional transmission of data frames between Ethernet devices (or nodes). It therefore relates in particular to vehicles, whether terrestrial, maritime (or fluvial), or air, facilities, possibly of industrial type, and buildings.
- FIG. 1 shows schematically a nonlimiting example of a network (of communication) RC of the Ethernet / IP type.
- the organs (or nodes) Ethernet Oj can be of any type.
- a car it may be a computer (possibly multimedia), a smart antenna of an infotainment module, a device for merging acquired images, or a screen.
- the invention proposes to equip each Ethernet member (or node) Oj of the RC network with a management device DG using in the application layer a new management protocol for the transmission and reception of Ethernet / IP frames used. (or generated) by any of the services provided by the different organs (or nodes) Ethernet Oj.
- These transmissions and receptions are intended to allow the realization of certain functions of management of the RC network, such as for example the control of the various phases of life of the RC network, the supervision of the organs (or nodes) Ethernet Oj to determine their connection status to the network, the testing of the different protocols used in the protocol stack of the TCP / IP model, and the realization of generic functional services (such as ensuring a message gateway between different technologies network).
- the management device DG of an Ethernet device Oj uses the new management protocol to transmit to the transport layer of this Ethernet element Oj, on a dedicated management port, a so-called management data frame tg.
- the latter (tg) comprises, as illustrated in FIG. 2, a message (or "payload" - useful data) that has been generated by a service provided by this Ethernet element Oj and which is intended for at least one other Ethernet device Oj '(j' ⁇ j), having a type and preceded by a header etg comprising first C1, second C2 and third C3 fields respectively identifying this service, this type and the length of the management data frame tg.
- the management device DG receives from the service of its Ethernet element Oj the message and the type of this message, and generates the management data frame tg by adding to this message a header including the first field C1 identifying this service, the second field C2 identifying the type of the message, and the third field C3 defining the length of the management data frame tg.
- the management device DG of an Ethernet element Oj also uses the new management protocol to transmit to a service of the application layer of this Ethernet element Oj a message (or payload) which has been generated by another Ethernet member Oj '(j' ⁇ j), having a type and preceded by a second field C2 identifying this type.
- this transmission is done after extraction by the management device DG in a management data frame tg, received from another Ethernet element Oj 'and communicated by the transport layer via the dedicated management port, of its message. and the second field C2 of its header etg, and determination of the destination service of this message and identified by the first field C1 of its header etg.
- each of the above-mentioned RC network management functions can be managed by each of the Ethernet members (or nodes) Oj, or can be distributed among several Ethernet members Oj.

- the latter (te) which is generated by the management device DG, comprises, as illustrated in FIG. 3, at least two tgk management data frames, each comprising a message generated by a service provided by the Ethernet element Oj, intended for at least one other Ethernet element Oj '(j' ⁇ j), placed one after the other, and encapsulated between a UDP header of the UDP protocol of the transport layer and a CRCMAC checksum field of the first network access layer of the TCP / IP model.
- checksum field (CRC or "CHECKSUM) is intended to allow an Ethernet device to verify that the frame it has received has not been altered during transmission.
- the first field C1 of the management protocol may comprise two bytes (or "bytes"). But it could include a single byte or three bytes. This number of bytes is a function of the number of services provided by the different organs (or nodes) Ethernet Oj RC network.
- the second field C2 of the management protocol may comprise two bytes (or bytes). But it could include a single byte or three bytes. This number of bytes is a function of the number of message types used by the services provided by the different organs (or nodes) Ethernet Oj of the RC network, to perform the various management functions of the network RC.
- a service designates a management function of the network RC. Therefore, a service may, for example, be selected from the phase control (s) life of the RC communication network, the supervision of at least one Ethernet member Oj, Oj 'to determine a connection state to the network of communication, the test of at least one protocol used in a protocol stack of the TCP / IP model, and the realization of at least one generic functional service (such as for example providing a message gateway between different network technologies).
- the type of a message characterizes a message in a service. For example, it is possible to have a wake-up frame for the control service of the life phases of the communication network RC, or a configuration frame for performing a test for the protocol testability service (s).
- the third field C3 of the management protocol may comprise a number of bytes of between three and five.
- this number of bytes can be equal to four (4).
- This number of bytes is a function of the maximum length that can present a management data frame tg (etg + message header) generated by a management device DG.
- dedicated management port may, for example, be at the address 1120 (in decimal).
- management device DG can be implemented at the level of the application software of an Ethernet device Oj. Therefore, it (DG) can, for example, be realized in the form of a combination of software modules (or "software").
- the invention requires the use of a small amount of computing resources (or CPU) and reduced memory. Therefore, the management devices can be easily implanted in all Ethernet devices (or nodes) of an Ethernet / IP communication network, without penalizing them.
