[Example] Hereinafter, a first example of the communication system according to the present invention will be described.

FIG. 1 shows the relationship between an operation device and communication equipment of a communication system according to this embodiment.

As shown in the figure, operation devices 101-10n and communication equipment 201-20m are connected by a communication path 1 via communication path interfaces 111-lln and 211-21m.

The operation devices 101 to Ions transmit the network management information sent via the communication path 1 to the communication path interface 1.
network management information receiving unit 141 that receives via 11 to lln;
~14n, identification units 121~12n that determine whether the network management information is from the target communication equipment, and identification units 131~ that determine whether the network management information is related to the target communication equipment.
13n.

In addition, the operation devices W101 to Ion are equipped with a means for executing fault processing, a man-machine interface means for displaying results, etc., but these are not directly related to this embodiment and are therefore omitted from illustration here. There is.

The communication installations 1201 to 20m each accommodate a transmission path (not shown), which accommodates various communication devices, and also sends network management information to the communication path 1 via the communication path interfaces 211 to 21m.

The communication path 1 is a bus-type communication path in this embodiment.

Next, the operation of the communication system according to the fifth embodiment will be explained.

This will be explained based on a typical example of operation.

In FIG. 1, a failure occurs on a transmission path (not shown) connecting 1 communication equipment 201 and 20m, and the 201 at both ends of the transmission path
By comparing the network management information detected at 20 m with the network management information detected at 20 m, consider a case where a failure occurs that can be recovered by the failure handling operation of the operation device 101.

First, the operation of the number of communications [201 to 20n] in this case will be explained.

FIG. 2 shows the processing procedure of the communication equipment 201 to 20n.

When the failure occurs, the communication equipment 201 and 20m detect this (step 2001) and send network management information to the communication channel 1 in broadcast format (step 200).

Furthermore, as a broadcasting format information transfer technology, the so-called 15
In addition to known point, to, and multipoint logical links using unconfirmed transfer mode in DN, there are various means for realizing this, but in this embodiment, in particular, Since this is not the case, its explanation will be omitted.

Next, the operations of the operation devices fll], 01 to Ion will be explained.

FIG. 3 shows the processing procedure of the operation devices 101 to 10n.

First, in advance, the operation device 1101 has the following information:
One communication facility 20n is registered as a target communication facility to be maintained, operated, and managed by the communication facility 201 as a communication facility that transmits network management information related to the target communication facility, and on the other hand, the operation device Ion The communication equipment 201 is registered as a communication equipment that sends network management information related to the target communication equipment, and the communication equipment 201
It is assumed that n is registered as a target communication facility to be maintained, operated, and managed.

The sent network management information is received by the operation devices 101 to Ions via the communication path 1 (step 3).
01), for example, based on the source address of the network management information, that is, the address representing the communication equipment 201, etc., the identification unit 121 determines whether the network management information is from the target communication equipment to be maintained, operated, and managed. Judgment step 302)
, since it is from the target communication equipment, it is taken into the network management information receiving unit 141.

Further, although the operation device Ion is not the target communication equipment, the identification unit 13n determines whether the network management information is related to the target communication equipment 20m (step 304), and the network management information is related to the target communication equipment. The information is taken into the network management information receiving section 14n.

Similarly, the network management information transmitted from the communication equipment 20m is determined by the identification unit 131 to determine whether the network management information is related to the target communication equipment or not. It is received by the operation device Ion by the function of the identification unit 12n.

Through the above-described one procedure, the information necessary to perform fault handling is imported into the operation device 1101 and Ion.

Through the above operations, each operation device has obtained network management information necessary for failure recovery processing.

Therefore, the operation device 101 performs the failure recovery operation based on the result of the captured information (step 306).

As described above, according to the communication system according to the present embodiment, each communication equipment does not need to obtain the information necessary for performing fault processing through exchange with the partner operation device Ion, so that prompt fault processing is possible6. On the other hand, in communication equipment as well, since the network management information is sent out in a broadcast format, it is only necessary to perform a simple process of sending out the information only once.

Note that since the network management information is sent out from the communication equipment in broadcast format, other communication equipment will also receive it.
This can be identified as network management information from other communication equipment and discarded as appropriate.

In addition, the operation device is configured to separately register the target communication equipment that is to be maintained, operated, and managed, and the communication equipment that sends network management information related to the target communication equipment. This is for the sake of flexibility, etc., and the two may be registered without distinguishing them as communication equipment that simply sends out the necessary network management information.

Next, a second embodiment of the communication system according to the present invention will be described.

In this embodiment, the communication equipment does not transmit the number of network management information in the transmission format, but transmits it so that it can be received only by a predetermined operation device, and furthermore, the transmission destination is set to the operation device that requested the transmission. This allows settings to be made from the device.

FIG. 4 shows the configuration of a communication system according to the second embodiment.

In addition to the components of the first embodiment, the communication system according to the present embodiment includes operation devices 101 to Ion that provide a network management information transmission destination instruction for instructing the communication equipment 201 to 20m as to the transmission destination of network management information. The communication equipment 201-20m includes network management information destination instruction receiving units 241-24m.

It includes network management information destination changing sections 251-25m, network management information destination management sections 231-23m, and network management information sending sections 221-22m.

Hereinafter, similarly to the first embodiment, the communication equipment 201 and 20
The operation of the communication system according to the present embodiment will be explained by taking as an example the operation when a failure occurs on a transmission path (not shown) connecting the communication terminals m.

FIG. 5 shows the processing procedure for one communication facility 201.20m.

When the communication equipment 201.20m detects a failure (step 501), the network management information destination management unit 231.23m determines whether the destination of the network management information has been determined (step 502).

Then, if it is determined, the necessary network management information is sequentially sent to the destination from the network management information sending units 221 to 22m (step 503).

With this, for example, if it is specified that network management information related to a failure on the transmission path detected by one communication equipment 201 is to be sent to the operation device Ion other than the operation device 101, the information can be transferred via the operation device. You can directly access network management information without
It can be sent to the operating device that requires it.

Note that the setting of the network management information transmission destination is performed as follows.

First, an operation device that requires network management information instructs each communication facility to transfer the fault information to 151 to 15n.
(Step 6 in Figure 6)
01).

On the other hand, this
4m (step 701 in FIG. 7), the communication equipment changes the network management information destination changing unit 251 to 25 according to the content.
m changes the contents of the network management information destination management units 231 to 23m (step 702 in the figure). In each of the above embodiments, the bus communication path was shown as the most suitable communication path for realizing the present invention. This may be, for example, something that connects each communication equipment and the operation device using a ring-shaped communication path or the like, as long as the communication equipment and the operation device are equivalent when viewed from the communication path.

In addition, although failure information has been explained as an example of network management information,
Transmission of other general network management information can be similarly realized.

[Effects of the Invention] As described above, the present invention provides a network that allows an operation device to quickly obtain necessary network management information from communication equipment through simple processing. A management communication method and communication system can be provided.
