Abstract
The process disclosed is appliable to transmission of data of the multiplexed series type between entities capable of emitting or receiving data, to or from the line. Each entity connected to the line can access all the data flowing in the line, and all the exchanged data are modeled by a distributed data base which is updated and maintianed by the fact that each entity stores and updates a local copy of the corresponding useful part of the data base it contains. Each time an entity is placed in service, a coherence check is carried out to ensure that the emitting and consuming entities interpret data in the same way. The coherence check is carried out by a protocol without prior contact or acknowledgement.
