A system for optimising routing of traffic in a multilayer telecommunications network is described. The multilayer telecommunications network comprises a first layer and a second layer in which a subset of links in the first layer are served by the second layer. The system is configured to receive network topology data describing topology of the first layer and of the second layer and to receive service requirements data describing data transport services required of the multilayer telecommunications network. The system is configured to generate a flat model by modelling the multilayer telecommunications network as a single-layer telecommunications network, the flat model being based on the network topology data and excluding links of the first layer that are served by the second layer. The system is configured to optimise routing of traffic through the single-layer telecommunications network based on the service requirements data and the flat model using a routing engine, and to convert the optimized routes through the single-layer telecommunications network into first-layer optimized routes through the first layer of the multilayer telecommunications network and second-layer optimized routes through the second layer of the multilayer telecommunications network. |
