Network management method and system

A method for managing a network composed of a plurality of managed objects using managed-object instances which are hierarchically organized in inclusion relation, the method comprising the steps of:

• a) detecting addition of a network element device to the network;
• b) creating a managed-object instance corresponding to the network element device;
• c) creating a processing object corresponding to the network element device, wherein the processing object recursively creates a child processing object for accessing a component included in the network element device;
• d) recursively returning information obtained by a lower-level processing object to a higher-level processing object based on the inclusion relation;
• e) storing a collection of information received by the processing object onto the managed-object instance to add the network element device as a managed object to the network;
• and
• f) reporting the addition of the network element device to a network manager.

A system for managing a network composed of a plurality of managed objects, comprising:

• a network manager;
• a memory storing a plurality of managed-object instances which are hierarchically organized in inclusion relation, each managed-object instance corresponding to a different managed object;
• and
• a processor for searching the memory for a managed-object instance designated by an access request received from the network manger, for recursively creating a processing object for accessing a managed object included in the designated manage object based on the inclusion relation and recursively returning information obtained by a lower-level processing object to a higher-level processing object based on the inclusion relation, and for returning a collection of information received by the designated managed-object instance to the network manager.

A system for managing a network composed of a plurality of managed objects, comprising:

• a network manager;
• a detector for detecting addition of a network element device to the network;
• an access controller for accessing the network element device to obtain information of the network element device;
• a memory storing a plurality of managed-object instances which are hierarchically organized in inclusion relation, each managed-object instance corresponding to a different managed object;
• and
• a processor for creating a managed-object instance corresponding to the network element device and a processing object corresponding to the network element device, wherein the processing object recursively creates a child processing object for accessing a component included in the network element device through the access controller, for recursively returning information obtained by a lower-level processing object to a higher-level processing object based on the inclusion relation, for storing a collection of information received by the processing object onto the managed-object instance to add the network element device as a managed object to the network, and for reporting the addition of the network element device to the network manager.
