TECHNICAL FIELD OF THE INVENTION
The present invention provides, in a communication network using a plurality of communication protocols, a failure communication protocol and failure information of the communication network to a network management device, and the failure information and a failure propagation range in the plurality of communication protocols caused by the failure. And a display device for enabling a failure notification method to be displayed on a screen of a management device.
[0002]
[Prior art]
The conventional communication network management apparatus handles only a specific communication protocol, and notifies and displays failure information including a failure point related to the communication protocol as an alarm. The display of the failure alarm is only the configuration display screen of the communication protocol and the failure information display screen.
[0003]
FIG. 4 shows a method for displaying failure information in a network management device in such a conventional communication network of a single communication protocol. In FIG. 4, it is assumed that the interface (IF) card 106 of the router B has failed. Along with this failure, failure information of the IF card of the router B itself is displayed as a failure alert on a failure information display screen 102 3 of the display screen 101 of the IP network management device as shown by 103. Subsequently, related information due to the failure, that is, a timeout of the router A is also displayed on the failure information display screen 102 as shown by 104. At the same time, the configuration display screen 105 displays that the router B is a fault location and that the router A is a location related to the fault by coloring (discoloration display) or the like by a related alarm.
[0004]
Such a conventional management device cannot handle a plurality of communication protocols simultaneously. In the case of a failure in the communication protocol that is not handled by the management device, only a related alarm caused by the failure can be notified, and an accurate failure location cannot be displayed. FIG. 5 shows an example of display of failure information in a network management device in a communication network using a plurality of communication protocols. In this case, the related information resulting from the failure on the ATM protocol, that is, the timeout of the router A and the router B on the IP protocol are displayed on the configuration display screen 112 and the failure information display screen 113 in the display screen 111 of the IP network management device. However, it is not possible to accurately display the fault location 114 on the ATM protocol.
[0005]
In addition, in order to obtain failure information of a plurality of communication protocols, the configuration display screen and the failure information display screen of a plurality of management devices corresponding to the communication protocol used by the managed network must be mutually confirmed. Further, during the operation of the management device corresponding to a specific communication protocol, it is not possible to immediately check the fault information and the fault location generated by another communication protocol.
[0006]
FIG. 6 shows another example of the display of the failure information in the network management device in the communication network of the plural communication protocols. In this case, on the display screen 121 of the IP network management apparatus, a failure alarm (VP disable and ATM switch failure) 128 on the ATM protocol due to the failure of the ATM switch A129 is not notified. A related alarm (router B timeout and router A timeout) 124 on the IP protocol resulting from this failure is displayed on the failure information display screen 123. Also in the configuration display screen 122, not the exact failure location, but only the location (router A and router B) related to the failure is displayed by coloring. For this reason, a failed communication protocol cannot be immediately determined.
[0007]
On the other hand, a failure alarm (VP disable and ATM switch failure) 128 on the ATM protocol is displayed on the failure information display screen 127 on the display screen 125 of the ATM network management device in FIG. On the configuration display screen 126, the ATM switch A that has notified the failure information is displayed by coloring. However, it is not possible to specify a failure spread range to another communication protocol (IP protocol).
[0008]
For this reason, the operator grasps the configuration of the entire network of a plurality of communication protocols, such as X for router A and Y for router B, while alternately checking the two management devices, and specifies the communication protocol in which a failure has occurred. There is a need.
[0009]

In the communication protocol described above, an alarm indicating a failure spread range is displayed on a failure display screen, and the alarms are propagated and displayed on another display screen related to the alarms.
[0012]
According to the present invention, it is possible to notify and display not only a failure point and a failure alarm in one communication protocol but also a failure propagation range in a plurality of communication protocols caused by the failure. Become. Further, by simultaneously handling a plurality of communication protocols, there is no need to mutually confirm the failure information display screen and the configuration display screen of a plurality of management apparatuses.
[0013]
Further, even if a failure occurs in another communication protocol while operating a display screen of a certain communication protocol, the failure may occur due to the association between the plurality of databases for each communication protocol and the data by the inter-layer cooperation management unit. By specifying and displaying the fault spread range caused by the fault, it is possible to immediately confirm the fault spread range corresponding to the fault on the operating screen even while operating a display screen related to another communication protocol.
