    Abstract: The present invention relates to a method of synchronisation between communication networks exchanging information by frame of informations, each communication network having clock and the number of clock pulses is monitored by a counter. The synchronisation is made by reading information representing the counted clock pulses of the clock of the first network at the appearance of a reference event, inserting at least said information or calculated information on the basis of said information into the frame of information as the synchronisation information, transferring said frame of information from the first to the second network, reading information representing the number of counted clock pulse of the clock of the second network at the appearance of reference event, reading synchronisation information inserted in received frame of information from the first network, calculating a difference between information and synchronising the second network.

    Abstract: In order to adjust the maximum size of the information sequences transmitted by a plurality of terminals in a network, according to a predetermined network protocol, between two subnetworks supporting different maximum sizes of information sequence: there is stored in an information base, for each of the terminals, an identifier for this terminal and the maximum size of the information sequences allowed by the network protocol for communicating with this terminal; the information base is updated from the analysis of any information sequence conveyed in one of the subnetworks; then, for each information sequence to be transmitted: the identifier of the destination terminal and the corresponding maximum size of the information sequences are read in the information base; the maximum size read is compared with the current maximum size allowed by the network protocol; and, if the maximum size read is less than the current maximum size, the current maximum size is adjusted by allocating to it the value of the maximum size read.

    Abstract: The methods for transmission of sequences or frames of data provide for retransmitting, with a central device (21), frames of data which reach it, to destination devices, by transmission of downlink frames when the destination device is a peripheral device (24), each downlink frame having systematically a service message activating a protocol controlling access to the transmission medium shared by the central device (21) and the peripheral devices (24), and possibly a frame of data. The central device (21) and at least one peripheral device (24) form a system which is particularly well suited to a local area network, notably with a wireless transmission medium.
