DIGITAL DATA EXCHANGE ARCHITECTURE FOR USE IN AVIONICS APPLICATIONS

摘要

This digital data exchange architecture (10) comprises at least one communication network (12) having at least one communication plane (P1, P2, P3), a plurality of electronic devices (19, .., 22). subscribers, and several switches. Each switch comprises means forming a time referencing server capable of: generating a local current time reference; transmitting this local current time reference generated on the corresponding communication plane (P1, P2, P3) via a frame; receiving, via one or more frames, the current time references generated by at least some of the switches of the corresponding communication plane (P1, P2, P3); analyzing the received current time references to generate a local next time reference according to a predetermined generation law; - associate the next local time reference with the current local time reference.
