Abstract: The invention relates to a method for synchronizing interconnected critical devices comprising servers and clients, each critical device being connected to another critical device by a virtual link, each termination of which is associated with a minimum and a maximum value of transmission time for a data packet, the method, implemented periodically, comprising: the reception of a message at a reception instant, said message comprising at least one time reference determined by a transmitter server, for each message received, the estimation of the current time of the transmitter server on the basis of: the time reference, a value of the internal clock of the current critical device at the current instant and at the reception instant, the minimum value and the maximum value of transmission time of the virtual link between the transmitter server and the current critical device.

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.
