In data networks struggle with errors it is integral to the integrity of the data. One way to reduce errors in the transmission channel are methods of data transmission, such as a Idle RQ (Repeat reQuest), Go back N and a SR (Selective Repeat). The above methods of data enable evaluation of the data link layer protocols developed under the influence of interference of various nature on data channels. Taken into account the effect of interference in the retransmission of the channel, and the channel length dependence of the size of the frame on the likelihood of errors in the frame as well as the number of attempts before a successful transmission of a frame. Existing methodology for assessing the performance of data-link protocols developed in assuming the absence of interference on the data channels. The mathematical expectation of the number of attempts until the first successful delivery of the frame, the dependence of the real performance of the protocols under conditions of noise for different access technologies in mono.
