Abstract: A switch for transmitting digital data in the form of frames, each frame having an identification field and being of a first type conforming to an ARINC 664 P7 type protocol or of a second type conforming to an IEEE 802 type protocol. The switch comprising a plurality of input ports, a plurality of output ports, and a configuration table comprising for each identification value of the transmission parameters of the frames having this identification value. The switch is able to switch each frame between an input port and at least one output port exclusively on the basis of the transmission parameters corresponding to the identification value of this frame in the configuration table, independently of the type of this frame.

Abstract: The present invention relates to an avionic communication system that comprises a plurality of switches and a plurality of equipment units. Each equipment unit is capable of generating digital data that are present in the form of a plurality of frames of the first type that are in compliance with a first protocol, or of the second type that are in compliance with a second protocol. Each switch and each receiving equipment unit are configured so as to determine the type of each frame received and, as a function of the determined type, to process this frame in accordance with the corresponding protocol, each frame of the first type being processed on a prioritised basis in relation to each frame of the second type. The first protocol is of the type ARINC 664 P7 and the second protocol is of the type Ethernet with predetermined routing.

Abstract: The present invention relates to a switch including a plurality of input ports, a plurality of output ports, at least one output port, called observation port, being connected to an observation module able to analyze the traffic of the frames passing through via the switch, and a conveying component configured to convey each frame. The switch is configured to transmit, to the observation modules via the observation port, only frames according to a first observation condition and a second observation condition. The compliance of a frame with the first observation condition is determined as a function of an observation field and the compliance with the second observation condition is determined as a function of the identifier and/or of an input and/or output port associated with this frame.

Abstract: The present invention relates to a switch comprising a plurality of input ports, a plurality of output ports, and a first routing component that is capable of routing each frame of a first type in compliance with a first protocol between at least one input port and one output port associated with this component. The switch in addition comprises a second routing component capable of routing each frame of a second type in compliance with a second protocol between at least one input port and one output port associated with this component, and an allocation interface capable of associating each input port and each output port with the first routing component or with the second routing component, in accordance with a predetermined configuration.
