Communications method using a multiple-access distributed protocol in a network, and internal or external network intended to implement it

摘要

Communications method using a multiple-access protocol in a network, characterised in that: . an open station, which is disabled for the first time since it became open, interrupts its transmissions at the end of the current transmission; . an open station, which is disabled at least for the second time, sends, at least, L+1 frames as soon as it detects a low-level signal if it has sent at least L+1 frames, while it redetects a high-level signal, it interrupts its transmissions, at the latest at the end of the current transmission; otherwise it stops sending L+1 frames before interrupting its transmissions; . a closed station which is disabled remains in the closed state, even if it has local frames to transmit. This invention is of interest to manufacturers of computer and communication hardware and appliances. IMAGE
