PROBLEM TO BE SOLVED: To enable speed-up of setting or change of plural transmission routes over plural domains.SOLUTION: A first management server refers to transmission route setting information regarding a first restoration face to generate connection change information of the first restoration face for defining a first connection point which is connected to a second network on a specific first transmission route and a second connection point which is prohibited from being connected to the second network on the specific first transmission route, and transmits the connection change information of the first restoration face to a second management server for managing the second network. On the basis of the connection change information of the first restoration face, the second management server changes a second transmission route connected to a first network at the second connection point out of a second transmission route group constituting a second active face to a third transmission route which does not pass via the second connection point, but passes via the first connection point, whereby the first network is operated at the first restoration face, and the second network generates transmission route setting information regarding the second active face and the first restoration face which is operated at the second active face.SELECTED DRAWING: Figure 1 |
