Subject of Research. We study organization of machine-to-machine exchange over aggregated channels divided into groups. For requests on packages transfer a common queue can be arranged. As a result of multiple access for each request at the same time the resources of all channels in the group are provided. A package copy is transmitted through each channel. Methodology of Research. Study of machine-to-machine exchange effectiveness is based on analytical modeling. Due to the identical character of channels and the simultaneity of their provision to a packet transmission, it is assumed that all copies will be delivered to the recipient at the same time, although transmission errors or packet loss are possible. That proves the channel group representation as a one servicing device. Main Results. We have shown the efficiency of redundant transmission organization of copies of packets over aggregated channels divided into groups. We have defined the boundaries of appropriate application of redundant transmission of packets, time-critical to their unmistakable delivery over the aggregated channels divided into groups. Practical Relevance. The proposed models can be used in selection of decisions aimed at the organization of redundant transmission over the aggregated channels.
