Description

  The present invention relates to a reliability determination system and method for a redundant communication line.

  In general, it is required to maintain high system reliability for communication facilities of a communication network. For this reason, conventionally, when a failure occurs in the standby transmission line due to the duplication of the active system and the standby system, a technology for notifying the occurrence of the failure to the active system and ensuring the reliability of the system is known (patent) Reference 1). In addition, in a redundant system of an active system and a standby system, a technique for self-diagnosis of an abnormality in the online operation of the standby system device before switching to the active system is known (see Patent Document 2).

  However, the above-described conventional system has a problem that it cannot be applied to a system configured redundantly by a plurality of routes such as a power security communication line. If the communication line is configured redundantly to increase reliability and the communication line is configured across multiple facilities (maintenance points), each redundantly configured route is a separate facility. In many cases, it passes through the area of the jurisdiction. For this reason, when each route stops due to a failure, the communication network monitoring system notifies the failure to the facility jurisdiction of the terminal equipment in which the route on the side where the line is stopped is accommodated. Yes. In addition, in the trunk line, failures for all facilities (for all maintenance points) are monitored at the central monitoring point.

  However, if a part of the circuit route stops due to a failure or stoppage, there is no report to the facility jurisdiction through which the sound route side of the circuit passes. Cannot recognize that the degree is decreasing. In other words, for a line that has been stopped due to a communication failure or stoppage, that fact is notified to the facility jurisdiction of the route that is the subject of the stop, but the facility jurisdiction of the healthy section of another route that is not subject to the suspension Has no notification of stop information. For this reason, at the facility jurisdiction of the healthy section of the other route that is not subject to the stoppage, the route is sound, but the other route becomes incommunicable and the reliability of the line itself connecting the bases is reduced. There is a problem that you can not. For this reason, for example, work on equipment related to a healthy route line without knowing that the reliability of the line itself connecting the bases has decreased at the place of jurisdiction in the sound section of other routes that are not subject to suspension If the system is implemented, there is a possibility that the system will be stopped and all the lines connecting the bases may be unable to communicate. However, in order to maintain the soundness of communication, every time a route subject to suspension occurs, search for all passing points and related equipment based on the circuit configuration diagram for the sound route. However, there is a problem that it takes enormous labor and time to contact the relevant jurisdiction.

  The present invention has been made in order to solve the above-described problems. When a failure occurs or a planned stop operation is performed, a line connecting the bases to all the facility jurisdiction through which the healthy route passes is provided.

The threshold information IF is set in advance by the operator based on the degree of the number of serviceable healthy routes in the redundant configuration line route between the communication bases. That is, the number of stop routes (the number of planned stop routes in the case of the plan information PL) N that is allowed to ensure the soundness of communication with respect to the number of healthy routes in the redundantly configured circuit route between communication bases is N It is set as the threshold value TH. For example, as shown in FIG. 5, when there are three routes 001 to 003, the threshold value TH is set so that when two of them stop, it is determined that the reliability is lowered. In other words, if a plurality of routes are secured, it is determined that the route is sound and the reliability is not lowered. Note that this threshold TH is not limited to the number N of stopped routes, but is a stop route stop rate R that is acceptable for ensuring the soundness of communication (for example, routes that are stopped for three or more routes). The stop rate is considered to be healthy when it is 50% or less, and if it is higher than that, it is determined that the reliability is lowered.) Further, the number of healthy routes necessary for ensuring the soundness of communication or the ratio of healthy routes to stop routes may be used.

Based on the FT, the configuration management database 21 extracts a suspended line for the route of the redundantly configured line in the corresponding section (see 1-4 in FIG. 1). When the plan information PL (stop facility information PLeq and stop date / time information PLdt) is sent from the work plan management unit 31 (see 1-2 in FIG. 1), the stopped line extraction unit 32 also receives the plan information. Based on the PL, the configuration management database 21 extracts the line scheduled to be stopped for the route of the redundant configuration line in the corresponding section (see 1-4 in FIG. 1). Both the failure information FC-FT and the plan information PL may be input to the stopped line extraction unit 32, or only one of them may be input. When only the failure information FC-FT is input, the line that is stopped is extracted, when only the plan information PL is input, the line that is scheduled to be stopped is extracted, and when both are input, the line that is stopped Lines scheduled to be stopped are extracted.
