<p>PURPOSE:To simplify the constitution by obtaining the string of loops tying nodes obtaining a duplicated path from unit loop information and adjacent loop information so as to generate the information of the duplicated path. CONSTITUTION:A unit loop input means 1 inputs and stores the information of unit loop of a communication network and an inter-loop adjacent check means 3 checks whether or not the unit loops are adjacent to each other based on the unit loop information read out of the unit loop storage means 2 and the result is outputted as the adjacent loop information. Moreover, the adjacent loop information storage means 4 stores the adjacent loop information and the labelling method execution means 5 obtains the string of loops tying the nodes to obtain the duplicated path from the unit loop information and the adjacent loop information. Then the path information generating means 6 generates the information of the double path from the string of loops and the path information output means 7 outputs the generated path information. Thus, the correspondence at revision is facilitate and the constitution of the path information generator is simplified.</p> |
