Abstract: This invention relates to an installation for downloading/uploading information between at least one item of equipment (2a, 2b) onboard an aircraft, and offboard means (6) of loading/unloading information, the onboard equipment (2a, 2b) communicating through a first type A communication bus according to a first protocol P, and means (6) of loading/unloading information, communicating through a second type B communication bus using a second protocol Q.

Abstract: This invention describes a switched full-duplex Ethernet type communication network comprising at least one source subscriber equipment (13) and at least one destination subscriber equipment (14) connected to each other through at least one physical link through at least one switch and at least one virtual link (VL), which is the conceptual representation of a link from a source equipment (13) to at least one destination equipment (14), in which each equipment transmitting Ethernet frames comprises:

Abstract: The invention relates to a process for checking the deterministic behavior of a packet switching network comprising subscriber stations connected to each other through at least one switch, this behavior being said to be deterministic in the sense that every packet sent on the network from a source subscriber station joins the destination subscriber station(s) within a limited time, characterized in that the following relation is satisfied for each output port on each switch on the network: 1 i ⁢   ⁢ number ⁢   ⁢ of ⁢   ⁢ virtual ⁢   ⁢ links passing ⁢   ⁢ through ⁢   ⁢ the ⁢   ⁢ buffer   ⁢ [ 1 + int ( ( Jitter ⁢   ⁢ In ) i ⁢ i + max ⁢   ⁢ Latency BAGi ) ] * ( max ⁢   ⁢ frame ⁢   ⁢ duration ) ≤ max ⁢   ⁢ latency

Abstract: The invention relates to a process for implementation of a redundant switched full-duplex Ethernet type communication network comprising at least two independent elementary networks, each elementary network (RE1, RE2) comprising at least one source subscriber equipment and at least one destination subscriber equipment, connected to each other through at least one physical link through at least one switch, each equipment being connected to each of these elementary networks (RE1, RE2) in which a frame by frame redundancy is made on each elementary network.

Abstract: The present invention relates to a flow control device in a switched network comprising at least one transmitter device and at least one receiver device linked together through at least one switch (20), in which a virtual link, which is a logical link using at least one physical link, allows information to be sent from a transmitter to at least one receiver, in which each switch (20) contains an allocation table (T), defined statically, which associates a bandwidth with each of the virtual links so as to guarantee a maximum transmission period of an element of information in each virtual link and an allocation such that for every physical link the sum of the bandwidths allocated to the various virtual links using this physical link is less than the bandwidth of this physical link.
