A network design apparatus includes a first processing unit configured to determine a communication route that connects predetermined nodes by selecting one or more paths provided between the nodes in a network, and to perform an estimation of communication lines opened in each of the selected one or more paths; a second processing unit configured to perform an estimation of communication apparatuses constituting the communication line and a housing that accommodates the communication apparatuses, for each node in the network, based on an estimation result of the first processing unit; and a third processing unit configured to determine whether there is a possibility of reduction in the number of the housings due to a change in the communication line, for each node in the network, based on respective estimation results of the first processing unit and the second processing unit. |

1. A network design apparatus comprising:
a first processing unit configured to determine a communication route that connects predetermined nodes by selecting one or more paths provided between the nodes in a network, in response to traffic demand between the predetermined nodes in the network, and to perform an estimation of communication lines opened in each of the selected one or more paths; a second processing unit configured to perform an estimation of communication apparatuses constituting the communication line and a housing that accommodates the communication apparatuses, for each node in the network, based on an estimation result of the first processing unit; and a third processing unit configured to determine whether there is a possibility of reduction in the number of the housings due to a change in the communication line, for each node in the network, based on respective estimation results of the first processing unit and the second processing unit, wherein the third processing unit generates a constraint condition that causes the reduction in the number of the housings, based on a first upper limit number of the communication line, for each node, when the third processing unit determined that there is the possibility of reduction in the number of the housings, wherein the first processing unit performs again the estimation of the communication line according to the constraint condition based on the first upper limit number, and wherein the second processing unit performs again the estimation of the communication apparatuses and the housing, based on the result of the estimation that is performed again by the first processing unit. |
