Title: METHOD FOR DOWNLOADING SOFTWARE FOR COMPUTERS VIA A TIME-DIVISION MULTIPLEXING NETWORK
Abstract:
The invention relates to a method for downloading requests for writing applications software data into the memory of computers (4, 4a, 4b), the write requests being transmitted to the computer or computers (4, 4a, 4b) in initial frames via a first local area network, then, after conversion into modified frames, being transmitted via a second time-division multiplexing network having a plurality of communication channels, parameterised according to a repetitive communication cycle comprising the sending of one modified frame per channel (4, 4a, 4b), characterised in that: - the initial frames are segmented into modified frames, each containing a number of bytes less than or equal to a maximum number permissible by the channel, - when, during the communication cycle, one or more free channels exist, the free channels are reassigned to the remaining computer or computers in order to send additional modified frames, - and recomposing the write request in the remaining computer or computers (4, 4a, 4b).
