Network management system uses managed object instances which are hierarchically organized in inclusion relation for recursively creating processing object and recuresively returning information

摘要

A network management method which can provide a reduced number of communication transactions is disclosed. A processing object is recursively created for accessing a child managed object included in a parent manage object based on the tree structure. The information obtained by a child processing object is recursively returned to a parent processing object based on the tree structure. A collection of information received by the top managed-object instance is returned to the network manager. A network element device is added as a managed object to the network by the collection of information is stored in a managed-object instance corresponding to the network element device.
