Claim 6

A communication network management system for monitoring on a display screen, operational status of network elements selected as objects of management among a plurality of components of a communication network, the management system comprising: a network manager for collecting status information of said objects of management from the communication network, each of the status information being associated with one of said objects of management specified by an instance which includes an address name indicative of where the corresponding object belongs in said communication networks; display terminal with a display screen located remote from said network manager and coupled through a transmission path with said network manager for presenting network configuration on the display screen in which a change in the operational status of each of the objects of management is indicated by changing a display status of a graphic representation representative of the object, wherein said display terminal further includes; first table means for defining relationships between the instance of each of objects of management to be displayed on the screen and a display identifier assigned to the object; second table means for defining relationships between coordinate data of each of graphic representation of objects to be displayed on the screen and a display identifier corresponding to the object; communication control means for informing said network manager of the relationships between the instance and the display identifier defined in said first table means; wherein said network manager further includes; data table means for indicating relationships between the instance of each of said objects of management and a display identifier assigned to the instance and informed from said display terminal; and means for transmitting status information of one of said objects collected from said communication network to said display terminal together with the display identifier corresponding to the instance of the object which is specified by referring to said data table means, whereby said display terminal operates to change on the screen a display status of one of the graphic representations specified by the display identifier and in accordance with the status information received from the network manager.

Claim 7

A communication network management system as set forth in claim 4, wherein said display means includes display data conversion means for converting object management information to be displayed into a symbol shape having a distinct color.

Claim 8

A network management/display processing method in a communication network management system including a network manager for collecting management information, including operational status, of physical objects in a communication network, each of the physical objects having an instance which is a model address of the corresponding physical object in said communication network, and display means located remote from said network manager and coupled through a transmission path to said network manager for displaying operational statuses of the physical objects in said communication network, on a display screen by displaying graphic representations of said communication network physical objects, said method comprising the steps of: creating, in said display means, a display identifier indicative of physical object management information to be displayed on said display screen; transmitting relationships between an instance of the physical object management information to be displayed and said display identifier from said display means to said network manager; creating, in said network manager, a data table for storing the management information of the physical objects which were collected from said communication network along with their associated display identifiers; selecting, in said network manager, the management information of physical objects to be displayed that have a same display identifier from said data table; and transmitting said selected management information with the display identifier from said network manager to said display means.

Claim 9

A network management/display processing method in a communication network management system including a network manager for collecting management information, including operational status, of physical objects in a communication network, each of the physical objects having an instance which is a model address of the corresponding physical object in said communication network, and display means located remote from said network manager and coupled through a transmission path to said network manager for displaying operational statuses of the physical objects in said communication network, on a display screen by displaying graphic representations of said communication network physical objects, said method comprising the steps of: creating, in said display means, a display identifier indicative of physical object management information to be displayed on said display screen; transmitting relationships between an instance of the physical object management information to be displayed and said display identifier from said display means to said network manager; creating, in said network manager, a data table for storing the management information of the physical objects which were collected from said communication network along with their associated display identifiers; selecting, in said network manager, the management information of physical objects to be displayed that have a same display identifier from said data table; and transmitting said selected management information with the display identifier from said network manager to said display means.

Claim 10
