Embodiment Construction

[0034] figure 2 The illustrated subscriber 10 is a subscriber of a vehicle-borne communication network, which is a deterministic Ethernet network using virtual links, each of which has an associated BAG constraint. The subscriber comprises a first receiver 20a of a communication port compatible with the communication network (designation R1 on the figure), and a first transmitter 22a of a communication port compatible with the communication network (designation T1 on the figure). It also includes a first memory 19 (named MEM1 on the figure). The first memory is provided to record a configuration table related to a set of virtual links that a subscriber can receive and / or forward. The configuration table includes a list of virtual links that subscribers can receive and / or forward. The subscriber 10 is the receiver of the virtual link and / or the information that the virtual link should be forwarded by the subscriber 10 . The subscriber 10 also includes a receive function 12 ...

Abstract

The invention provides an onboard communication network and a vehicle and a subscriber of such a communication network. The subscriber of a deterministic Ethernet communication network using virtual links includes a first receiver (20a), a first transmitter (22a), a first memory (19) to record a configuration table relating to a set of virtual links that the subscriber can receive and/or retransmit, a processing unit which is configured to implement at least one application (18), a reception function (12) to receive data frames received by the first receiver (20a), to accept the reception only of the frames corresponding to virtual links belonging to the set of virtual links and to transmit these frames to a sorting function (16) to transmit the data frames received to the application (18) and/or to a transmission function (14) to dispatch the data frames received to the first transmitter (22a) while complying with Bandwidth Allocation Gap (BAG) constraints associated with the corresponding virtual links.

Description

technical field [0001] The invention relates to the field of communication networks, and in particular to the field of communication networks carried in aircraft. Background technique [0002] Aircraft generally include one or more on-board communication networks provided to allow communication between on-board equipment, in particular on-board computers. In order to meet the specification requirements for aircraft certification, the on-board communication network should be deterministic, that is, it should allow transmission from one or more transmitting devices subscribed to the communication network to one or more The information transmission of the receiving device, at the same time, the transmission time is less than the predetermined time and the information is not lost through the network. Part 7 of the ARINC 664 standard defines a deterministic loaded avionics communication network based on full-duplex switched Ethernet technology. Such a network may for example co...
