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 (named RI on the figure), and a first transmitter 22a of a communication port compatible with the communication network (named 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 may 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 receiving module 12 (named "rece...

Abstract

A vehicle-borne communication network and subscribers to the communication network. Deterministic Ethernet using virtual links comprising: a first receiver (20a); a first transmitter (22a); a first memory (19) provided to record associations with a set of virtual links that a subscriber can receive and / or forward and a processing unit configured to implement: at least one application (18); a receiving function (12) configured to receive a data frame received by the first receiver (20a), for only when the data frame corresponds to the The virtual links in the set of virtual links accept the reception and transmit these frames to the screening function (16); transmitting the received data frame; and a transmitting function (14) configured to transmit the received data frame to the first transmitter (22a) subject to the BAG constraints associated with the corresponding virtual link.

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...
