FIELD: information technology.
SUBSTANCE: invention relates to transmission of information in computer networks with return channel. Method of transmitting-receiving messages in communication systems consists in the fact that at the transmitting side of the initial message is broken into portions of k bits is formed of frames with a protocol HDLC by ARQ on h steps back transmitted h frames over a communication channel at the receiving side in control protocol sequence HDLC detected erroneous frames, if erroneous frames are absent, information recipient is generated bit k , otherwise wash frame with errors, the reception of the next h-1 frames over reverse channel command is sent request and transmitting side repeatedly sends these h frames.
EFFECT: technical result consists in increase of rate of receiving information owing to reducing the probability of repeated requests.
