In this paper, we present the method for reducing the probability of indefinite looping in single-layer (non-hierarchical) telephone network of Electric Power Utility. The method is based on the detection of the first loop after the reception of two initial signalling messages, which contain the same source and destination addresses. In this case the network node, where the first loop is detected, changes its routing plan. The method can’t eliminate loop appearance completely, and it is not applicable when overlap signalling is used.

PL

W artykule opisano metodą redukcji prawdopodobieństwa wystąpienia pętli warunkowych w jednowarstwowej sieci telefonicznej operatora energetycznego. W metodzie dokonywana jest detekcja pierwsze pętli, o takim samym adresie źródłowym i docelowym, która wystąpi po wykryciu wiadomości inicjalizacyjnych. Następnie następuje zmiana routowania. Metoda nie eliminuje pętli w zupełności.
