1. An end system for an avionics communication system, the avionics communication system further comprising a plurality of switches connected together to form one or more computer networks, the end system being configured to be connected to at least one of the switches to receive and/or transmit digital data in the form of frames through that switch;
each frame having an identification field and being of a first type or a second type, the identification field of each frame defining an identification value, the frames of the first type conforming to a protocol of an ARINC 664 P7 type and the frames of the second type conforming to a protocol of an IEEE 802 type, the set of frames of the first type having a same identification value forming a single flow of the first type and the set of frames of the second type having the same identification value forming a single flow of the second type;
wherein the end system comprises at least one input port capable of receiving frames, and a configuration table comprising for each identification value parameters for processing frames having that identification value;
wherein the end system is able to determine a processing protocol for each frame received via the input port exclusively from the processing parameters corresponding to the identification value of this frame in the configuration table, independently of the type of this frame;
wherein the end system further comprises at least one output port adapted to transmit frames of first type and/or second type; and
wherein the end system is configured to transmit each second type frame at a timing period predefined by the identification value of that frame, frames of the first type being transmitted with priority over frames of the second type.
