A method of designing a network circuit for a telecommunications network includes storing first model data in a database representing a first model of the telecommunications network. The first model data defines network nodes and connections between network nodes in the telecommunications network. Second model data is received representing a second model of the telecommunications network. The second model data defines node groups, each representing a plurality of network nodes of the first network model, and interconnections between node groups, each representing connectivity between node groups in the first network model. The method involves searching the second model data to select a route from a start node group to an end node group, the route specifying a plurality of node groups connected by interconnections in the second network model; and searching the first model data to select a circuit from a node of the start node group to a node of the end node group. The circuit comprises a plurality of nodes connected by connections in the first network model. The nodes of the circuit are selected from the nodes of the node groups specified by the route. Also mentioned are methods of selecting routes by including potential connections, or airgaps, between nodes in which connectivity is possible but is not actually in place; selecting nodes for a route by use of filtering rules; and selecting routes based upon specification of a start point, an end point and at least one of a plurality of stored rules. |
