FIELD: communication. SUBSTANCE: for each terminal 2-9 method involves continuation of transmission of data elements after successful transmission of first element, waiting for acknowledgment of reception of this element, limiting number of sent elements during waiting represented as W, suspending transmission of elements during given period Tr if reception has not been acknowledged before current end of transmission of elements, transmission of new first element, if corresponding acknowledgment has not been received during period Tr and releasing communication line which services this terminal if acknowledgment has not been received after given period Tmax which is measured starting from first transmission of first element. Said values W, Tr, Tmax of current service type are given for each terminal. For network 1 control method in overflow case involves setting parameters W, Tr, Tmax for each connection, depending on service type for this connection, delaying sequence of elements which are transmitted in each connection in series by time which is less than Tmax, removing element and other identical elements which are sent by connection which is limited to corresponding loss of element by level below Tmax. EFFECT: increased functional capabilities. 2 cl, 2 dwg
