Most network management systems use SNMP (Simple Network Management Protocol)[3] and CMIP (Common Management Information Protocol)[4] protocols, which are based on a centralized paradigm. These protocols use the clientserver model, on which the management station acts as a client that provides a user interface to the network manager and interacts with agents, which are servers that manage remote access to the Management Information Base (MIB). The operations available to the management station for obtaining access to the MIB are very low level. This fine grained client-server interaction, called micro-management, generates an intense traffic that overloads the management station, resulting in scalability problems. At the same time that the networks grow, the computational power of the managed element increases, making possible to perform management functions in a distributed way. In this …
