Abstract: A method for transferring data representing a network topology from a first software environment to a second software environment is provided. The data are reformatted for this purpose, since it is assumed that the different software environments support different file formats, as is the case, for example, with customary network design programs or network simulation programs. Furthermore, the data are reorganized before or after the reformatting in such a way that a different mapping of the network topology results. Consequently, the method allows an automatic transfer of network topology data from one software environment into another, even though the two software environments use different data formats and different topology representations.
