A method of configuring, by a client user using a personal computer, at least one user-specific connection between access points of a transmission network, which are connectable to user-located network devices, the method comprising the steps of:
- determining, using the personal computer, network data related to other network devices of the transmission network which differ from the user-located network devices, and about links between the other network devices via which the at least one user-specific connection can be established;
- generating network planning data for a representation of the transmission network, on the basis of which at least one availability criterion of the other network devices or of the links between the other network devices is determinable;
- and
- providing the network planning data for a configuration tool for allowing the client user to configure the at least one user-specific connection, the configuration tool generating the representation on the basis of the network planning data;
- wherein the network data contains information of the structure of the transmission network and the availability and loads of the network devices, and the network planning data specifies geographical data of access points;
- wherein the network planning data is derived from network data representative of a network topology of the transmission network;
- generating the network planning data on the basis of the network data, and
- generating a graphical representation of the transmission network on the basis of the network planning data by determining availability criteria of the network devices and the links and configuring the user-specific connection.
