A method for re-configuring a network element of a transmission network to restore traffic after occurrence of a failure is proposed. Each configuration request is divided into two phases: At first a 'fetch-ahead' phase and then a 'consolidation'. During fetch-ahead, only configuration steps essential for fast implementation of a new cross-connection are performed and security related configuration steps skipped thereby providing reduced security against process restarts. During consolidation, those previously skipped security related configuration steps are then executed and the changes made persistent.

Fast reconfiguration of network elements

Operating data of a controller for a network element must be saved in a nonvolatile storage. The operating data are present in the form of managed objects. The method of saving the operating data involves dividing the managed objects into groups (A, B, C) and assigning a group-specific software module to each of the groups. To save one of the managed objects (MO) the operating data of the object are stored using the associated group-specific software module (MOD_A, MOD_B, MOD_C). This makes it possible to take into account the different requirements with respect to access capabilities, robustness, and speed of the different managed objects, and to increase access speed.
