Minimization of losses in networks with different-type channels while transmitting group messages

In up-to-date multinetworks that connect global networks engaging dozens of different corporate networks with permanently growing volumes of transmitted information the share of group information is growing. However, under multicasting the information transfer protocols still do not take into account such network features as the configuration of disposition of the addressees and information recipients, different parameter values of telecommunication channels and different loads at network nodes. In actual practice of network operation such discrepancies can be of significant, or sometimes crucial importance for telecommunication network functioning and receiving the information of acceptable quality. The authors propose the method of information transmission routes selection when telecommunication network with diversified channels in multicasting mode is used. Peculiarities of the group nature of transferred information and possibilities of their accounting for decreasing the load and losses in telecommunication networks are considered.
