Methods for IT network representation and associated computer program products
First Claim
1. A method of creating an IT-network representation including automatically discoverable active elements and passive elements, comprising:
- producing, by running a network auto-discovery tool, a logical discoverable-elements representation of the IT network which includes the automatically discoverable active elements and a discoverable-elements network topology;
manually inserting, by a user by means of a network-element editor, representations of passive elements between automatically discovered elements into said discoverable-elements representation, thereby creating a combined logical representation which models the IT network with its automatically discoverable elements and passive elements.

Abstract
A method of creating an IT-network representation including automatically discoverable active elements and not automatically discoverable, passive elements. A logical discoverable-elements representation of the IT network is produced, by running a network auto-discovery tool. The representation includes the automatically discoverable active elements and a discoverable-elements network topology. Representations of not automatically discoverable elements are manually inserted, by a user by means of a network-element editor, between automatically discovered elements into said discoverable-elements representation. Thereby a combined logical representation is created which models the IT network with its automatically discoverable elements and non automatically discoverable elements.

15. A method of performing fault diagnosis in an IT network having automatically discoverable active elements at routing- and switching-layers and passive elements at a physical layer, comprising:
-
using a combined logical representation of the IT network produced by running an auto-discovery tool and by inserting, into a representation automatically obtained by the auto-discovery tool, passive elements between automatically discovered elements, said combined logical representation modeling the IT network with its automatically discoverable active elements and passive elements;
locating a fault down to the switching layer in response to a fault detection;
indicating, as a result of the fault-diagnosis method, possible physical-layer elements responsible for the fault, based on the known fault location at the switching layer and information from the combined logical IT-network representation which passive elements are located between routing- or switching-layer elements at the switching-layer fault location. - View Dependent Claims (16)

17. A computer program product which is either in the form of a machine-readable medium with program code stored on it, or in the form of a propagated signal comprising a representation of program code,
wherein the program code is arranged to enable a user to carry out a method, when executed on a computer system, of extending a discoverable-elements IT-network representation by passive elements, said method comprising: -
using the logical discoverable-elements representation which includes automatically discoverable active elements and a discoverable-elements topology, produced by running a network auto-discovery tool;
manually inserting, by means of a network-element editor, representations of not automatically discoverable elements between automatically discovered elements into said discoverable-elements representation, thereby creating a combined logical representation which models the IT network with its automatically discoverable elements and passive elements.

wherein the program code is arranged to carry out a method, when executed on a computer system, of performing fault diagnosis in an IT network having automatically discoverable active elements at routing- and switching-layers and passive elements at a physical layer, said method comprising: -
using a combined logical representation of the IT network produced by running an auto-discovery tool and by inserting, into a representation automatically obtained by the auto-discovery tool, passive elements between automatically discovered elements, said combined logical representation modeling the IT network with its automatically discoverable active elements and passive elements;
locating a fault down to the switching layer in response to a fault detection;
indicating, as a result of the fault-diagnosis method, possible physical-layer elements responsible for the fault, based on the known fault location at the switching layer and information from the combined logical IT-network representation which passive elements are located between routing- or switching-layer elements at the switching-layer fault location.
