How to provide rerouting information for damaged cables {Method to provide rerouting information for damaged cables}

The present invention provides a method and method for providing a detour transfer information for providing a detour transfer information for replacing a damaged cable in the cable management module of the facility management field in the inter-station relay general management system for managing a transmission facility. The present invention relates to a computer-readable recording medium recording a program for realizing the present invention. More specifically, the method and method for providing bypass switching information for providing bypass switching information by extracting subscriber and line information accommodated when a cable is damaged are described. A computer readable recording medium having recorded thereon a program for realization.

Here, the bypass switch refers to replacing cores in damaged cables by using core cores of other cables which are not damaged for quick recovery of subscribers and circuits accommodated in damaged cables.

In order to perform the bypass switching, it is necessary to know what optical line is accommodated in the damaged optical cable, and that the subscriber or transmission line information connected to the received optical line should know which optical line is to be transferred and which optical line should be preferentially transferred. have. In addition, in order to replace the optical fiber to be transferred, the idle core information must be grasped to provide information for transferring the damaged optical fiber A to the idle core A '.

Next, the terms of the optical cable and the optical fiber used in the present invention and the optical carrier defined in the present invention are as follows.

An optical cable is a physical connection between stations that carries optical signals from optical stations. Each optical cable includes an optical fiber. When the core wire is patched, the optical cable and the core wire are managed on a local-to-local basis. Damage to the optical cable due to natural disasters or artificial causes means that the fiber optics inside are damaged at once.

The core is the physical wire included in the cable. Each core is used to construct an optical carrier, and is divided into a transmission core and a reception core according to a transmission direction, and two cores are used together to form a carrier.

An optical carrier defines an optical carrier as the core connection between devices when several cores are connected and connected to a device of an operating station. Therefore, the optical carrier is composed of at least two of the transmitting core and the receiving core, and a core patch may occur so that two or more cores may be used. According to the type of optical station equipment of each operating station (90M optical station, 565M optical end station, 155M optical end station, 622M optical end station, 2.5G optical end station ...), it is defined as 90M optical carrier and 155M optical carrier.

Core patch connects core and core in Optical Fiber Distributer (OFD), one of the distribution facilities. The core patch (connection of core and core) is connected to the optical end station of each terminal locality via several localities.

Optical Fiber Distributer (OFD) is a distribution facility connecting core patches, core and optical repeaters, and core and optical end stations.

In the conventional method for obtaining the detour switching information, it was managed only to grasp which optical fiber was accommodated through the manual cable management. Accordingly, the conventional method has a problem that it takes a lot of time to recover because the management of the manual process is often accurate.

In addition, in the related art, even when the core wire information contained in the damaged cable is obtained manually, it is difficult to obtain the bypass switching information of the idle core wire to replace it. In other words, due to the absence of information management for all optical cables in the headquarters, in addition to the cable information of the own station, the idle core line of the primary or secondary (when passing through one or two other local areas) other than the idle core of the direct section of the country. It was difficult to grasp the information, and there was a problem that it was impossible to quickly recover the subscribers and lines that were accepted due to the old-fashioned transfer.

The present invention has been proposed in order to solve the above problems, and extracts the core information of the target object to be transferred, sets the priority criteria for this, sets the priority, and then applies the idle core information according to the priority. It is an object of the present invention to provide a method for providing bypass conversion information for extracting and providing bypass conversion information, and a computer-readable recording medium storing a program for realizing the method.

In order to achieve the above object, the present invention provides a cable bypass switching information providing method applied to a system for managing a line, wherein the priority is given to the extracted core wire information after the line management system extracts the core wire information to be transferred from a database. A first step of prioritizing according to the criteria; And a second step in which the circuit management system extracts idle heart line information by applying idle heart line selection criteria according to the priority given in the first step and provides detour switching information.

On the other hand, the present invention provides a line management system having a processor, comprising: a first function of giving priority to a line management system according to a priority criteria for extracting core wire information extracted after extracting core wire information to be transferred from a database; And extracting idle heart line information by applying the idle heart line selection criteria according to the priority given by the first function, and recording the program for realizing the second function of providing the detour transfer information. Provide a recording medium.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary configuration diagram of a computer system to which the present invention is applied.

With reference to Figure 1 extract the core information of the transfer target and set the priority criteria for this setting to determine the priority, and then apply the idle heart line selection criteria according to the priority to extract the idle heart line information to provide detour transfer information The following briefly describes the composition of the integrated management system between stations.

As shown in FIG. 1, a computing system to which the present invention is applied includes an input / output device 14 for inputting / outputting data with an external operator, an auxiliary storage device 13 for storing data, and the input / output device. Commands input by the operator and data stored in the auxiliary storage device 13 through 14 are read into the main storage device 12 to extract the core wire information of the target object, and to set the priority criteria for the priority. After the determination, the microprocessor 11 is configured to provide idle bypass information by applying idle core line selection criteria according to priorities.

For this purpose, the optical fiber of the target object to be transferred is extracted by using the database-related optical cable information of the inter-station relay management system, and the switching priority is given according to the priority criteria proposed by the present invention and idle according to the priority. Search the core wire to provide detour transfer information. Even when extracting the idle core is to follow the idle heart line selection criteria proposed by the present invention.

FIG. 2 is an exemplary view for displaying an optical cable, an optical core line, and an optical carrier, showing an optical cable and an optical core line, and an optical carrier defined by connection of the optical core line.

Since the optical carrier is composed of several core wires, each core wire has optical carrier information. Accordingly, in the present invention, it is possible to apply a selection criterion to which cores should be restored first by using the optical carrier information of the damaged optical cores. The method of giving priority to the optical carriers using the damaged optical cores proposed in the present invention is as follows.

When the optical cable is damaged and broken, first, the optical carrier information connected to the optical core wires received in the optical cable is extracted. In assigning priorities, the granting criteria should be prioritized when connected to subscribers and used exclusively, and prioritized according to the characteristics of asynchronous devices that do not switch automatically and synchronous devices that operate automatically as spare optical carriers. Will be given. [Table 1] below is an example of priority criteria for optical carriers to be transferred.

Priority Priority criteria Contents One Other telecom business and general purpose (asynchronous) Optical carrier used exclusively for other communication businesses and general large subscribers 2 Rental core connected to subscriber FLC device Core Lending due to FLC (Fiber Loop Carrier) device at subscriber side 3 565M in operation 565M-class optical carrier in operation (N + 1 unit switching is provided at the system level so automatic switching of cable units is not possible) 4 90M in operation 90M optical carrier in operation 5 Synchronous (2.5G, 622M, 155M) Priority is low because 1 + 1 unit is switched and is operated after switch-over in case of failure. 6 Asynchronous Spare Optical Carrier (565M, 90M Order) Spare optical carrier for asynchronous devices

Figure 3 is an example of the idle core (core) selection criteria for the bypass switching of the optical cable according to the present invention.

Selection criteria also exist in selecting idle cores for transfer to cores housed in damaged optical cables. First, select from the same route and select from the bypass route so that the bypass route selection can be selected if all cables in the same route are disconnected at the same time. Also, if the same route does not exist or there is no idle core, the bypass route selection method is applied in the system, and when selecting the bypass route, it defines the selection criteria for providing efficient transfer information and provides bypass idle line information that meets the conditions. Done.

[Table 2] below is a standard for selecting idle cores. The criteria listed are selected priorities and are provided as transfer information when there is an idle core suitable for the relevant criteria. If there are no idle cores meeting the criteria, a search for an idle core suitable for the next criteria is performed.

Selection criteria Explanation One Idle core in the same route optical cable (If the bypass route is selected as priority, this selection criterion is excluded from the selection criterion.) 2 Idle core on optical cable in optical carrier direct section 3 Direct cable lower carrier direct section (direct section between upper station of cable and lower station of carrier) (If terminal of carrier is subscriber, jurisdiction is regarded as local of carrier.) 4 Lower Carrier Direct Carrier Direct Section (Direct Section between Lower Station of Cable and Upper Station of Carrier) 5 1st detour of cable section (by bypassing 1 other station for broken cable and provide idle core information) 6 1st round bypass of carrier section (by bypassing 1 other station for carrier section and providing idle core information) 7 1st bypass of the upper cable lower carrier (bypassing one station in another station between the upper station of the cable and the lower station of the carrier) 8 1st bypass of the lower cable upper carrier (bypassing 1 station in another station between the lower station of the cable and the upper station of the carrier) 9 Secondary bypass section between carrier end stations (bypassing two other stations for carrier section) (except secondary bypass of cable section will be via many localities) 10 3rd bypass section between carrier stations (bypassing 3 other stations for carrier section)

When explaining the concepts of upper and lower here, each local is named as an upper station or a lower station with respect to the relative local. By managing the order of the upper and lower stations of each local station, it is possible to know whether the local station is the upper station or the lower station according to the relative local station. The upper and lower stations used in the idle core selection criteria are already managed by the telecommunication operators (KT, etc.). The transfer information is provided according to the idle core selection criteria for the core wire in use (when it has optical carrier information) accommodated in the damaged cable.

Next, a method of managing transfer information after the transfer function according to the present invention will be described. A separate table is managed in the database in order to manage the transfer information generated as a result of the receiving core cable and the bypass switching function of the transfer target cable. The optical carrier information, transmission / reception classification, and priority of the transfer target of the core having optical carrier information among the damaged cores of the damaged cable are managed, and the selection of idle optical cores can be performed sequentially according to the order of these priorities. In addition, it manages the transfer information generated as a result of the bypass transfer function, and manages the damaged core information and the idle core information after performing the transfer function to replace it. Such transfer information management prevents the selection of redundant idle cores and provides information on which damaged cable is present. In addition, the information provided in the database is provided when the damaged cable is recovered after the recovery operation is completed.

4 is a detailed flowchart illustrating an embodiment of a method for providing bypass switching information of a damaged optical cable according to the present invention.

First, when a report of a damaged cable is received (41), the core wire accommodated in the damaged cable is retrieved from the database (42). Priorities are given to cores constituting the optical carrier among the receiving cores according to the priority criteria of the optical carrier (43, 44). The assigned priority, optical line and optical carrier information are stored (45). Thereafter, the optical carrier and optical fiber number are extracted 46 in order of priority.

Subsequently, check whether the same route priority is performed (47), and in the same route priority case, search for other cable idle cores in the same section first (48), that is, determine whether an idle core line exists according to idle core selection criteria 1 (50). ). On the other hand, if it is not the same root priority, that is, when the bypass route is performed first, the selection criteria 2 are applied (49). Subsequently, the selection criteria I are continuously applied until the idle core exists (52).

As a result of the checking (50), if there is no idle core, the next selection criterion (I = I + 1) is applied to search for the idle core (51) and continues to apply the selection criteria (I) until the idle core exists. (52).

On the other hand, if the result of the check 50, the idle core is stored in the optical core information before and after the optical carrier transfer (53). Subsequently, the above-described priority order optical carrier and core line number extraction process 46 are repeatedly performed until all the detour switching information for each damaged optical carrier is obtained (54).

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes can be made in the art without departing from the technical spirit of the present invention. It will be apparent to those of ordinary knowledge.

The present invention as described above, by providing a database of the optical cable-related information to provide the transfer information for all the cables in the headquarters as well as the own station, and direct (direct) and primary, secondary bypass cable transfer information By providing it, there is an effect that can reasonably improve the conventional irrational bypass switching method.

In addition, the present invention gives priority to which optical fiber should be preferentially switched to minimize the damage caused by cable damage, and even when extracting the idle core, the idle core information is transferred to the transfer information under an efficient and reasonable system. There is an effect that can be provided.

In addition, the present invention is managed accurately and quickly in the database so that when the detour transfer function needs to be performed in accordance with the other cable damage, the core cable of the damaged cable and the idle cable of the transfer target can be excluded from the detour transfer function performing target The cable management is effective.
