Abstract: The method is applied to configure, reconfigure and monitor globally a plurality of network elements (NE1, . . . , NEi, . . . , NEj, . . . , NEN) connected to an IP Network (10) through multiple interfaces (A1, . . . , AN), with several Network Elements Controllers (NEC1, . . . , NECk, . . . , NECQ) connected to the same IP Network (10) through respective interfaces (B1, . . . , BQ). The IP Network (10) also provides a plurality of preconfigured IP functional interfaces (Cik) from each network element (NEi) to the at least one network elements controller (NECk). Each network element (NEi) has an IP networking layer (9) and runs/executes several network-related processes (P1, . . . , PL) managed and monitored by this method. The method also provides configuration and monitoring of IP interfaces (Dij) among network elements. The existing IP functional interfaces (Cik) are used to perform such managing and monitoring. To get these aims, the method performs high-level actions instead of atomic “get/set” operations. Neither the method neither requires explicit agents-manager paradigm nor depends on a particular communication protocol for network management.
