Method and apparatus of deterministic transmission of packetized asynchronous data

The present invention relates to a method deterministic transmission of asynchronous data packetized, wherein data arriving from asynchronously are stored in stacks (11) As they arrive, said method comprising the steps of:reception of data contained in a set of batteries in one of several formatting modules in packets (13), packetizing first set package with sorting and enrichment of data, end of the packetization, and consists of sending packet,stopping the formation of the package progress in a packetization module (13) when a message composition module (15) has need this package, packet transmission and constituted the beginning of the cycle for a new package,recovery one after the other thus created packages in a predefined order, in message composition module (15)put the message, made in the module of message composition (15) in electrical format in the protocol used for transmission. The invention also relates to a deterministic data transmission device Asynchronous set package.
