The main reason for overloading most telecommunication networks is the finite number of buffers in the switching nodes and the limited channel resource associated with the cost of the channels. Within the limits of the article the algorithm of optimization the self-recovering link of a telecommunication network is developed and possibility of reception technically realizable analytical decision of a problem is provided, using as the limiting condition of cost transfer quantity of the information falling for unit of channel capacity. The scientific novelty of solving this problem consists in using combined switching methods, in particular, in a packet network to transport long messages by hybrid channel switching. The identity of using cost functions of one or another kind, which simplifies the choice of the cost function that most fully corresponds to the conditions of a particular problem is described in the article.
