This digital data exchange architecture includes at least one communication network having at least one communication plane, a plurality of pieces of subscriber electronic equipment, and several switches. Each switch includes means forming a time referencing server able to: generate a local current time reference; transmit this local current time reference generated on the corresponding communication plane via a frame; receive via one or several frames the current time references generated by at least some of the switches of the corresponding communication plane; analyze the received current time references, in order to generate a local following time reference according to a predetermined generation law; and associate the local following time reference with the local current time reference.

Digital data exchange architecture usable in avionic appliations

A hierarchical distributed architecture including services and applications able to manage and/or process digital data by using the services. The architecture includes local service providers, each local provider being connected to one or several applications, and remote service providers, each remote provider being connected to one or several services, each application able to communicate with one or several services through a first hierarchical level including a local provider, and a second hierarchical level including at least one remote provider and each service is able to communicate with one or several applications through a first hierarchical level including a remote provider and a second hierarchical level including at least one local provider.

Hierarchical distributed architecture with multiple access to services

This switched data transmission system, particularly for use in avionics applications, of the type comprising a plurality of electronic devices and equipment units adapted for transmitting discrete messages over a transmission network, and in which each of the devices and equipment units is connected to a network switch, the switches being connected to each other by means of data transmission links so as to form a physical topology of a loop network, each message being associated with information regarding data flow priority in the network comprising of functional priority information, is characterized in that each message is also associated with information regarding temporal priority of data flow in the network.
