The present invention relates to an integrated equipment failure determination system, method, program, and recording medium in a PDH mixed communication network.

  A so-called PDH system device used in a conventional PDH (Plicional Digital Hierarchy) communication network monitors failure information at a contact point, and outputs SDH (Synchronous Digital Hierarchy) as a message. G) Fault information is different from the device. For this reason, the equipment failure determination apparatus using the equipment failure determination method in the conventional PDH communication network cannot perform the failure determination for the SDH apparatus, that is, the equipment failure determination for the communication network including only the conventional PDH apparatus. In the system, the equipment failure cannot be determined based on the warning message issued by the SDH device, and the correct equipment failure cannot be determined in the communication network in which the PDH device / SDH device coexists. For this reason, in order to introduce the SDH device into the communication network, an equipment failure determination function of the SDH device is required.

  Patent Document 1 below discloses an SDH equipment failure determination apparatus that performs equipment failure determination related to an SDH apparatus for identifying a failure location from the occurrence of a communication failure in an SDH network.

  For example, in FIG. 1, the PDH equipment failure determination device 3 is a device that performs equipment failure determination regarding PDH devices in the SDH / PDH mixed communication network 1, and the SDH equipment failure determination device 2 performs equipment failure determination regarding SDH devices within the communication network. The device to be performed and the matching determination device 4 are devices that perform a matching determination between the failure determination result of the PDH device and the failure determination result of the SDH device, and identify a true main cause failure facility in the communication network. When a failure occurs in equipment in a communication network where SDH / PDH is mixed, a warning generated from various devices constituting the communication network is used as a contact alarm that is failure information related to the PDH device. The alarm message issued by the SDH device is determined using the SDH facility failure determination device 2 based on various data stored in the storage device 6, and the main cause facility information obtained by each determination is obtained. Based on the information held in the storage device 6, it is possible to make a match determination using the match determination device 4, identify a true failure facility in the communication network, and notify the communication network monitor using the output device 5. .

  According to the present invention, in a communication network in which PDH and SDH are mixed, failure determination is performed by integrating contact information and message information, which are various alarms that are output in response to a failure of a certain facility. Thus, it becomes possible to identify the true main cause equipment in the communication network in which PDH / SDH devices having different failure information are mixed.

  According to the present invention, regarding the SDH equipment failure determination, even when a new type of SDH device having a different output alarm is added to the existing communication network, the alarm is associated with the path and the hierarchical relation of the path. By changing the table that defines, it is possible to easily cope with it without revising the judgment processing logic. Further, even in a communication network in which PDH / SDH are mixed, the matching determination process can be performed by changing the connection relation between facilities and the main cause identification table.

  According to the present invention, by separately determining the failure of the PDH device and the SDH device, in the system in which the PDH failure determination device already exists as a device for determining the failure of the PDH communication network, the SDH device is included in the communication network. Even if it is added, it is not necessary to re-create the entire failure determination system, and the failure monitoring function of the SDH mixed communication network should be added in the form of adding the SDH facility failure determination function to the existing PDH facility failure determination system. Is possible.

  Embodiments of the present invention will be described with reference to the drawings. Referring to FIG. 1, the present embodiment targets an SDH / PDH mixed communication network 1 which is a communication network in which PDH devices / SDH devices are mixed, and collects various alarms output from each device constituting the communication network. Then, the failure equipment in the communication network is determined based on the collected alarm, and the PDH equipment failure determination device 3 that makes a determination on the PDH device, and the SDH equipment failure determination device 2 that makes a determination on the SDH device. A matching determination device 4 that matches the PDH failure determination result and the SDH failure determination result to identify a true failure facility in the communication network, and an output device 5 such as a CRT that outputs main cause facility failure information as the determination result, And a storage device 6 that holds various definition information used for SDH equipment failure determination and matching determination.

  When an equipment failure occurs in the SDH / PDH mixed communication network 1, contact information that is an alarm related to the PDH device in response to an alarm notified from various devices is failure information issued by the PDH equipment failure determination device 3 and the SDH device. A certain alarm message is subjected to failure determination processing by the SDH equipment failure determination device 2.

  The failure determination method in the PDH equipment failure determination device 3 uses a conventionally known method (a failure determination method using so-called umbrella logic), based on contact information which is an alarm regarding the PDH device in the communication network. It has a failure determination function that identifies a failure facility of the PDH device.

  The failure determination method in the SDH equipment failure determination device 2 uses the umbrella logic in the same manner as the failure determination method in the PDH communication network, and the facility failure determination in the communication network can be performed from an alarm message that is failure information issued by the SDH device. A failure determination function is provided.

  The matching determination device 4 performs a matching determination process according to the connection relationship (network configuration state) between the devices based on the respective failure main cause equipment information obtained as the PDH failure determination result and the SDH failure determination result, and SDH / PDH. One of these is determined as a true failure facility in the communication network. Since the PDH contact alarm and the SDH message alarm have different alarm collection paths and different numbers of failure alarms, the failure determination process by the PDH facility failure determination device and the failure determination by the SDH facility failure determination device. It is not possible to determine which process will end first. Therefore, in order to obtain true failure information from the PDH failure main cause information that is the determination result by the PDH equipment failure determination device and the SDH failure main cause information by the SDH facility failure determination device 2, which determination process ends first. As a matter of course, it waits until each other's determination processing is completed.

  Next, the detail of the structure relevant to the SDH equipment failure determination apparatus 2 and the matching determination apparatus 4 is demonstrated. The part / path correspondence storage unit 61 stores the correspondence between the device part and the path for generating a path status alarm corresponding to the path in the communication network 1 from the part information included in the alarm message output from the SDH apparatus. It is a device to memorize. By associating a path corresponding to the part in advance with the failure part information included as the content of the message alarm output from the SDH device, the path is associated one-to-one with each message alarm. (A path is a concept of a transmission path corresponding to the opposing relationship of multiplexing layers in a communication network). As for the path and part information of each SDH apparatus, the user inputs the path and the apparatus information constituting the path as network configuration information, so that the correspondence definition information between each part of the apparatus and an alarm generated from the part is previously stored. Correspondence is originally performed and stored in the part / path correspondence storage unit 61.

  The warning message conversion processing unit 21 searches the correspondence relationship between the warning and the path stored in the part / path correspondence storage unit 61 for the warning message issued from the SDH device received from the SDH / PDH mixed communication network 1. Then, the alarm message information is converted into a path status alarm corresponding to the path in the communication network 1.

  The path hierarchy relationship storage unit 62 is a device that stores the hierarchical relationship of paths in the communication network 1, and the paths generated by the alarm message conversion processing unit 21 for a plurality of alarms that are notified by equipment failure in the communication network 1. It is used to search the hierarchical relationship of the path stored in the path hierarchical relationship storage unit 62 for the information and specify the highest path on the path hierarchy. The path hierarchy relationship is also given to the SDH equipment failure determination apparatus 2 by the user as network configuration information.

  The main cause path stop determination processing unit 22 stores the path status alarm generated by the alarm message conversion processing unit 21 in which the alarm and the path are associated with each other in a one-to-one relationship. Based on the unit 62, path stop determination is performed in the order of the path hierarchy, and determination processing is performed in which the highest path in the path hierarchy is the main cause path. An alarm related to a path under a path determined as a main cause path is regarded as an alarm generated due to the influence of a main cause path failure, and is not regarded as a failure.

  The alarm level storage unit 63 assigns a level to each alarm in advance as a system in accordance with a chain of alarm messages generated at the time of equipment failure (relationship between alarms generated at the time of failure and alarms generated by other failure alarms). (Weighting) is performed, and an alarm level is stored for each alarm type.

  The main cause equipment failure determination processing unit 23 follows the alarm level stored in the alarm level storage unit 63 among the alarms generated at both ends of the main cause path obtained by the main cause path stop determination processing unit 22. It is determined that the facility where the higher level alarm is generated is the main cause of failure.

  The queuing condition storage unit 64 determines whether the PDH failure may be affected by the SDH failure or the SDH failure may occur depending on the connection relationship between the PDH device and the SDH device and the type of alarm according to the chain relationship of the alarm at the time of the failure. Pre-define whether there is a possibility of PDH failure, and whether or not the inspection of the possibility of influence by other failures is necessary, that is, the determination result of the other party (in the case of PDH determination result, SDH failure determination result or vice versa) Stores the presence / absence condition for waiting. In other words, the queuing condition storage unit 64 determines whether the PDH device and the SDH device are connected according to the relationship between the alarm generated at the time of the failure and the alarm generated by other failure alarms for each type of alarm. Definition information used for determining whether a device failure causes the other SDH device failure or an SDH device failure causes the other PDH device failure is stored, and the other failure causes the own failure. It stores condition setting information as to whether or not it is necessary to wait for the determination result as to whether or not a possibility test is necessary.

  The waiting processing unit 41 receives the determination results from the SDH equipment failure determination device 2 and the PDH equipment failure determination device 3, searches the conditions stored in the waiting condition storage unit 64 based on the respective determination result information, and waits. If it is determined that it is necessary, a process of waiting for a certain period of time for the failure determination result of the waiting party to be transferred to the waiting processing unit 41 is performed.

  The matching determination condition storage unit 65 stores a condition as to which failure information is the true main cause equipment when the failure information of the PDH device and the SDH device is matched, and is similar to the waiting condition storage unit. Are defined for each type of connection and alarm between the devices.

  The matching determination processing unit 42 is a matching determination condition storage unit based on the failure determination result of the PDH device by the PDH facility failure determination device 3 and the failure determination result of the SDH device by the SDH facility failure determination device 2 that are waited by the waiting processing unit 41. In accordance with the conditions stored in 65, it is determined which is the true main cause failure information (matching determination), and the true main cause equipment in the SDH / PDH mixed communication network 1 is determined.

  The output device 5 outputs true failure main cause facility information in the SDH / PDH mixed communication network 1 obtained by the matching determination device 4 to a CRT device or the like.

  Hereinafter, the operation of the determination system according to the present embodiment will be described in detail with reference to FIGS.

  In FIG. 1, when an equipment failure occurs in the communication network 1, the PDH equipment failure judgment device 3 sends contact information, which is PDH equipment failure information, from the SDH / PDH mixed communication network 1 to the PDH device monitoring network 8. Accept through. The PDH equipment failure determination device 3 collects the supplied contact information, performs failure determination processing, performs failure facility main cause determination regarding the PDH device among the devices constituting the communication network, and performs the PDH failure main in the communication network. The cause equipment is obtained and notified to the matching determination device 4.

  The SDH equipment failure determination device 2 receives alarm message information, which is SDH equipment failure information, from the SDH / PDH mixed communication network 1 via the SDH device monitoring network 7. The SDH equipment failure determination device 2 collects the supplied alarm messages, and first, based on the device part information in each alarm, the alarm message conversion processing unit 21 stores the alarm stored in the part / path correspondence storage device 61. And the path correspondence table are searched, and each alarm message is converted into path status information as path failure information. Each converted alarm message is associated with a path and becomes alarm information using the path as a key. As a result, each alarm can be handled as path status information, and a path failure status can be determined.

  A plurality of alarms output from the SDH device in the communication network when a failure occurs is given to the main cause path stop determination processing unit 22 as a path failure alarm generated by the alarm message conversion processing unit 21. The main cause path determination processing unit 22 searches the path hierarchy relation storage unit 62 for the plurality of path status alarms, sorts them in the path hierarchy order, and performs path failure determination in order from the highest path. When the alarm status in the path status alarm occurs, it is determined that the path is stopped, the highest path determined to be stopped is the main cause path of the failure, and the path status alarm related to the path under the main cause path is Considered as an effect of failure, not as failure. A path status alarm having a path determined to be the main cause path is passed to the subsequent main cause equipment failure determination processing unit 23.

  The main cause equipment failure determination processing unit 23 receives path state information related to the main cause path obtained by the main cause path stop determination 22, searches each alarm from the alarm level storage unit 63, and acquires the alarm level. When there are multiple path status information related to the main cause path, the equipment that has issued the highest level alarm among the acquired alarm levels is identified as the main cause equipment of the failure, and the main cause equipment information and alarm information Is notified to the matching determination device 4.

  The failure main cause facility information obtained by the PDH facility failure determination device 3 and the SDH facility failure determination device 2 is respectively passed to the waiting processing unit 41. In the queuing processing unit 41, the queuing condition storage unit 64 and the path hierarchy relation storage unit 62 are searched based on the failure main cause facility information of each SDH / PDH. In the case of the PDH facility, the SDH facility failure information is obtained. In the case of, it is determined whether or not to wait for the PDH facility failure information to perform the respective matching determination.

  When it is determined that no waiting is required, the failure main cause facility information is passed to the matching determination processing unit as it is, and the matching determination processing unit outputs the failure information as it is to the output device 5 without performing the matching determination as there is no matching partner. To do.

  When it is determined that waiting is necessary, it is necessary to determine the influence of another failure (PDH in the case of SDH, SDH in the case of PDH), so the failure determination result of the waiting partner is notified to the waiting processing unit. Wait for a certain time. When the failure information of the queuing partner is notified to the waiting processing unit during waiting, the failure information is notified to the matching determination processing unit for the first time.

  In the matching determination processing unit 42, which of the PDH main cause information and the SDH main cause information of the counterpart is used as the failure main cause information is obtained from the respective failure main cause information and the path hierarchy relation storage unit 62. It is obtained from the conditions stored in the matching determination condition storage unit 65 based on the connection relationship between the devices. Based on the search result from the matching determination condition storage unit 65, the true main cause facility of the failure is obtained and notified to the user via the output device 5.

  In the example of the communication network shown in FIG. 2, when the “A1 device” which is the SDH device fails, the alarm output from each device is from [a] to [i] as shown in FIG. The flow of failure determination will be described. The alarm [i] as contact information is notified to the PDH failure determination device via the alarm collection network of the PDH device, and the alarms [a] to [h] as message information are notified via the alarm collection network of the SDH device. The SDH failure determination device is notified.

  The PDH equipment failure determination device 3 performs a PDH facility failure determination process from the notified contact information [i], and determines the main cause equipment “A3 device” in the PDH device and the PDH path to be stopped as a determination result. “Path c1” is obtained (PDH equipment failure determination result).

  Next, the flow of SDH equipment failure determination will be described. The SDH failure determination apparatus 2 performs SDH facility failure determination based on the notified alarm messages [a] to [h]. Referring to FIG. 3, first, the alarm message conversion processing unit 21 refers to the part / path correspondence storage unit 61 based on the part information of each alarm from [a] to [h], and acquires the corresponding path. Then, the alarm message is converted into an alarm corresponding to the acquired path, the alarms [a] and [b] are the fault occurrence alarms of “path a1”, and the alarms of [c] and [f] are the faults of “path b1”, respectively. Similarly, [d] [g] is an alarm for “path b2” and [e] [h] is an alarm for “path b3” (step 1 in FIG. 3).

  The main cause path stop determination processing unit 22 searches the path hierarchy relation storage unit 61 for “path a1”, “path b1”, “path b2”, and “path b3” to change “path a1” to “path b1”. It can be seen that it is the highest-order path including “path b2” and “path b3”. Therefore, it is determined that “path a1” is the highest-order path during the reception alarm and is set as the main cause path of the failure. In addition, since the alarm state is generated, the determination that the path under the “path a1” is not regarded as a failure as a path affected by the failure of the “path a1”, the stop determination result of the main cause path is as follows: “Failure of path a1” is determined (step 2 in FIG. 3).

  The alarm messages [a] and [b] issued by the respective facilities regarding the “A1 device” and the “B1 device” that are the facilities that issue the alarm regarding the “path a1” that is the main cause path of the failure The alarm level is searched from the alarm level storage unit 63, and it can be determined that the alarm [a] issued by the “A1 device” is a higher level alarm. “A1 device” is specified. Thereby, “Failure of A1 device” is obtained as the failure main cause equipment in the SDH device (step 3 in FIG. 3).

  By the main cause path stop determination and the main cause equipment determination, the failure main cause information of the SDH equipment is obtained as a determination result (step 4 in FIG. 3).

  Next, the flow of matching determination will be described. In the matching determination device, the failure information of the identified “A3 device” that is the failure main cause facility in the PDH device in the communication network and the failure main cause facility in the SDH device are identified [A1 device]. Each failure information is received.

  In the case of this specific example, it is assumed that failure main cause facility information from the PDH facility failure determination device is notified to the matching determination device before failure main cause information from the SDH facility failure determination device.

  Referring to FIG. 4, when the path hierarchy relation storage unit 62 is searched based on “path c1” which is the main cause path of PDH failure information, it is determined that an SDH path exists at the upper level, that is, the SDH apparatus is positioned at the higher level. Determined to be connected. Information related to PDH failure main cause facilities and device connection relations When a waiting condition storage unit is searched on the condition that “the SDH device exists in the upper level of the PDH device multiple conversion device”, there is a need for waiting (PDH multiple conversion device May be affected by the host SDH device) and waits for SDH equipment failure information (step 1 in FIG. 4).

  After that, when the SDH equipment failure judgment device notifies the SDH equipment failure information to the queuing processing unit, the queuing processing unit uses the “A1 device” (the optical transmission device of the SDH device), which is the main causal equipment, to obtain the information. When the waiting condition storage unit 64 is searched for, it is determined that no waiting is required regardless of the connection relationship (step 2 in FIG. 4).

  The SDH failure information that is determined to be unnecessary and passed to the matching determination processing unit 42 can be identified as the main cause regardless of the PDH failure information by referring to the matching determination condition storage unit 65. Further, the path hierarchy storage unit 61 is referred to by “path a1” which is the main cause path, and the path is traced down to determine whether there is fault information waiting for the own fault information. It is checked whether or not failure information whose main cause path is waiting. Then, it can be determined that the PDH failure information having “path c1” as the main cause path is waiting for the SDH failure information. Referring to the matching determination condition, if there is a higher level SDH failure, the determination result is mainly due to the SDH failure (PDH failure information is determined to be a failure caused by the influence of the SDH failure information). Notification to the output device is not performed (step 3 in FIG. 4).

  The failure information of the SDH device that is the true main cause failure facility in the communication network obtained by the above-described matching determination is notified to the user via the output device as [REC of high speed section of A1 device has occurred].

  In the present invention, it is possible to provide a recording medium that records a computer program (equipment failure determination program) for causing a computer to execute the above-described facility failure determination method. This recording medium may be either a portable type or a fixed type, and may be a magnetic disk, a semiconductor memory, a CD-ROM or other recording medium. In addition, a computer program for executing this data analysis method can be stored in a recording device of a computer connected to a network, and transferred to another computer via the network. The providing medium that provides the computer program can be distributed as various types of computer-readable media, and is not limited to a specific type of medium.
