JPH03235443A - Trouble management system in communication network - Google Patents

Abstract

PURPOSE:To realize the integrated trouble management of a communication network by sending an alarm notification to an integrated agent from an agent to manage a managed object when trouble occurs in the managed object, and informing a manager of the trouble of the managed object from the integrated agent. CONSTITUTION:When the trouble occurs in a port 8, the agent 2 informs the integrated agent 4 of the alarm notification of the port 8 through the manager 1. Next, the integrated agent 4 finds that the port 8 is the constituent element of an end-to-end bus 7, and informs the manager 1 of the alarm notification purporting that the end-to-end bus 7 suffers the trouble. Thus, even in the case of the trouble management related to the managed objects extending over plural networks, it is no need to collect a trouble notification one by one from individual agent process, and the integrated trouble management of the communication network can be facilitated.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a fault management method for communication networks.

2. Description of the Related Art Conventionally, fault management operations for managed objects spanning multiple networks have been performed by application software for realizing communication network management receiving fault notifications one by one from individual agents.

Problems to be Solved by the Invention The above-mentioned conventional technology requires integrated communication in which a failure of an individual management target is related to a failure of a related management target due to the complexity of processing content of application software. The problem was that it was difficult to manage network failures.

The present invention has been made in view of the above-mentioned conventional situation,
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a new fault management method in a communication network that makes it possible to solve the above-mentioned problems inherent in the conventional technology.

Means for Solving the Problems In order to achieve the above object, the communication network fault management method according to the present invention provides
(i=1 , , , x) and each communication network N1
An agent Ai (i4, , , x) that manages a managed object Sj (j・1.', , y) belonging to a manager M that communicates with the agent A1 using the OSI management protocol, and this manager +M and the OSI management protocol. The integrated agent A communicates with the management target Pk (k=1...w) that cannot be managed by each agent Ai. (communication path of End (o-End)), and the managed target Ph is the component of the managed target S (m=1
．． ,,z), if a failure occurs in the managed target Sm, the agent A that manages the managed target Sm
fi sends an alarm notification to the integrated agent A, the integrated agent A recognizes the failure notification of the managed object Sm as a failure of the managed object Pk, and notifies the manager M of the failure of the managed object P. Thus, integrated communication network fault management is realized.

Embodiment Next, a preferred embodiment of the communication network management system according to the present invention will be specifically explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

In FIG. 1, reference number 1 indicates a manager, and this manager 1 is a managed object (Managed object).

ion) Communication is performed using the management protocol. Agent 2.3 manages managed objects belonging to the subnetwork. 4 indicates an integrated agent. Each agent 2.3 cannot manage objects that span multiple agents, such as end-to-end communication paths. To this end, in the present invention, an integrated agent 4 centrally manages management information managed across each agent and provides it to the manager 1.
is provided. A management application (not shown) that operates and monitors the managed target using a user interface is placed above the manager 1, and operations on the managed target are notified to the agent 2.3.4 via the manager 1. , executed.

Referring to FIG. 1, manager 1 is agent 2.
3 and integrated agent 4 by an O5I management protocol, and each agent agent 2.3 manages managed objects belonging to a communication network 5.6 by an arbitrary protocol.

Currently, the integrated agent 4 is managing an end-to-end communication path 7 as a management target, and this communication path 7 is a management target belonging to a boat 8 belonging to a network 5 as its constituent elements, and a management target belonging to a network 6 as its constituent elements. Suppose we have a certain boat 10.11. When a failure occurs in the boat 8, the agent 2 notifies the unified agent 4 of the alarm of the boat 8 via the manager 1. Integration agent 4 then discovers that boat 8 is a component of end-to-end path 7 and notifies manager 1 of an alarm notification that end-to-end path 7 has suffered a failure.

The flow of notification information during this time is shown in FIG.

As described in detail, according to the present invention, a network management application does not need to collect failure notifications from individual agent processes one by one even when managing failures regarding managed targets that span multiple networks. The effect is that failure management of an integrated communication network becomes easier.
