Description

  The present invention establishes communication between terminal packages installed in a transmission apparatus in a transmission apparatus composed of a plurality of space switches (SSW) and time division multiplexing switches (TSW: Time Switch). In particular, the present invention relates to a method for creating path setting data, and more particularly, to a path setting method for a communication network system and its control device.

  In a network system consisting of multiple transmission devices and transmission lines, when adding or removing transmission devices, or changing the transmission rate by changing the bandwidth allocation, etc. Changes may occur in the transmission path. In such a case, conventionally, a path is constructed by newly creating path setting information for each of the opposing transmission apparatuses, and individually transmitting and executing a path setting command to each transmission apparatus. .

  However, in a recent large-scale network, every time the path setting between transmission devices is changed, the path setting between transmission devices for all communication paths is reconstructed one by one. If it is set and executed, it takes a lot of time and labor to construct or change a new network. Furthermore, in such individual path setting, an artificial setting error occurs in a complicated network, and it takes time to check the path, and there is an increased concern that data loss or erroneous operation may occur. Was.

  In addition, a plurality of switches are arranged and configured in the transmission apparatus. In order to efficiently use the capacity of the switch unit, conventionally, a path between the terminal package and the SSW in the same apparatus is used. Setting data is individually set. In addition, path setting data between the transmission line (TSW) package and the SSW in the same apparatus is also set individually. The path setting data in the SSW is also set individually.

  Further, the terminal package is provided in an arbitrary transmission device, thereby enabling data communication between the terminal packages. Communication between terminal packages is realized via a network composed of a plurality of transmission devices and transmission paths. In this way, by setting a plurality of switches in the transmission apparatus individually as described above, a path can be set flexibly even in a complicated network. On the other hand, if the network becomes complicated and large-scale, the amount of network design work, the amount of design operation, and the amount of symmetrical data for design management increase. As a result, there is a concern that the reliability of creation of path setting data in individual correspondence is lowered.

Under such circumstances, the following methods have been conventionally proposed for the purpose of realizing simple path resetting. That is, when the opposite transmission apparatus is newly added, the opposite transmission apparatus that has detected the addition transmits the path setting information held by itself to the new extension transmission apparatus. The path setting information is used to set a path in its own transmission apparatus, and the extension transmission apparatus also performs path setting based on the received path setting information. This establishes a communication path between the two transmission apparatuses. For example, Patent Document 1 describes an example thereof.
WO2004 / 068803 JP 2006-222718 A

  However, in the conventional path setting, it is necessary to individually hold path setting information for each transmission apparatus and perform transmission / reception of the path setting for each transmission apparatus. Accordingly, the path setting is performed separately between the individual transmission apparatuses, and the path setting management data for each SW increases. Further, the number of setting operations for path setting is large, and the amount of work and the amount of management data at the time of changing the route are enormous. Therefore, a great deal of labor and time are required, and there is a concern about human error.

(Embodiment 1)
FIG. 1 shows, as an example of a network to which the present invention is applied, a transmission apparatus including a plurality of SW units and its network configuration. In this figure, a network system 1b is composed of four transmission devices, a transmission device A station 11, a transmission device B station 12, a transmission device C station 13, a transmission device D station 14, and a transmission path 1a.

  A telephone set 15 is connected to the terminal package 19 provided in the transmission apparatus A station 11. Similarly, the transmission apparatus C station 13 is provided with a terminal package (not shown) and a telephone set 16 connected to the terminal package. Communication between the telephone set 15 and the telephone set 16 is realized by establishing a network path between the transmission apparatus A station 11 and the transmission apparatus C station 13. In other words, communication is established by establishing a path between the terminal package 19 of the transmission apparatus A station 11 and the terminal package (not shown) of the transmission apparatus C station 13.

  Therefore, the transmission apparatus A station 11 includes a transmission path package 17 and an SSW package 18. The transmission path package 17 includes a cross-connect and is composed of a plurality of TSWs (Time Switch). The SSW package 18 includes a plurality of SSWs (Space Switch). Then, by turning these switches on / off, a path is set so that a communication network can be established between the target terminal packages.

Next, path setting will be described with reference to a path construction schematic diagram between two terminal packages shown in FIG. In FIG. 2, the same devices as those in FIG. 1 are denoted by the same reference numerals. This figure shows a case where communication is performed between the telephone set 15 connected to the transmission apparatus A station 11 and the telephone set 16 connected to the transmission apparatus C station 13.
The telephone 15 is connected to the terminal package 19 of the transmission apparatus A station 11. The terminal package 19 is connected to the port 1 terminal of the SSW package 18. Further, the port 8 terminal of the SSW package 18 is connected to the transmission path package (TSW) 17 (a). The transmission path package (TSW) 17 (a) is connected to the transmission path package 12 (b) of the transmission apparatus B station 12 via the high-speed external transmission path 25. That is, the transmission path package (TSW) 17 (a) of the transmission apparatus A station 11 and the transmission path package 12 (b) of the transmission apparatus B station 12 are connected, so that the transmission apparatus A station 11 And the transmission apparatus B station 12 can communicate with each other via the high-speed external transmission path 25.

  The transmission path package 12 (b) of the transmission apparatus B station 12 is connected to the transmission path package 12 (a) via the SSW package 22 of the transmission apparatus B station 12. That is, the switches of the SSW package 22 and the transmission path packages 12 (a) 12 (b) in the transmission apparatus B station 12 are set so that this connection is made. The device configuration in the transmission device B station 12 is basically the same as the device configuration in the transmission device A station 11. However, in this aspect, the transmission apparatus B station 12 does not include the telephone set 15, and therefore it is not necessary to provide the terminal package 19. The transmission path package 12 (a) is connected to the transmission path package 13 (a) of the transmission apparatus C station 13 through another high-speed external transmission path.

  In the transmission apparatus C station 13, each switch is configured so that a communication path is configured by connecting the transmission path package 13 (a) and the terminal package 29 via the SSW package 23. Is set. The device configuration in the transmission device C station 13 is basically the same as the device configuration in the transmission device A station 11. Further, since the transmission apparatus C station 13 includes the telephone 16, a terminal package 29 is provided. Thus, one communication path is established between the telephone set 16 connected to the terminal package 29 and the telephone set 15 connected to the transmission apparatus A station 11.

  On the other hand, in an actual communication network, it is necessary to secure a spare communication path in preparation for an emergency such as a communication failure. Therefore, another backup route is constructed in the same manner as described above. That is, the telephone set 15 is connected to the terminal package 19 of the transmission apparatus A station 11. The terminal package 19 is connected to the port 1 terminal of the SSW package 18. Further, the port 9 terminal of the SSW package 18 is connected to the transmission path package (TSW) 17 (b). The transmission path package (TSW) 17 (b) is connected to the transmission path package 14 (b) of the transmission apparatus D station 14 via the high-speed external transmission path 26. That is, the transmission path package (TSW) 17 (b) of the transmission apparatus A station 11 and the transmission path package 14 (b) of the transmission apparatus D station 14 are connected, so that the transmission apparatus A station 11 And the transmission apparatus D station 14 can communicate with each other via the high-speed external transmission line 26.

  The transmission path package 14 (b) of the transmission apparatus D station 14 is connected to the transmission path package 14 (a) via the SSW package 24 of the transmission apparatus D station 14. Become. The device configuration in the transmission device D station 14 is basically the same as the device configuration in the transmission device A station 11. However, since the transmission apparatus D station 14 does not include the telephone set 15, it is not necessary to provide the terminal package 19. The transmission path package 14 (a) is connected to the transmission path package 13 (b) of the transmission apparatus C station 13 through another high-speed external transmission path.

  In the transmission apparatus C station 13, each switch is configured so that a communication path is configured by connecting the transmission path package 13 (b) and the terminal package 29 via the SSW package 23. Is set. The device configuration in the transmission device C station 13 is basically the same as the device configuration in the transmission device A station 11. Further, since the transmission apparatus C station 13 includes the telephone 16, a terminal package 29 is provided. As a result, another backup communication path is established between the telephone set 16 connected to the terminal package 29 and the telephone set 15 connected to the transmission apparatus A station.

The setting data in the SSW package (connect) 18 is, for example, an address 1 from the port 1 to the port 8 direction with the band 5 and an address 1 from the port 1 to the port 9 direction. There is data of band 5, band 5 at address 1 from port 8 to port 1, and band 5 at address 1 from port 9 to port 1.
In the transmission line package (cross connect) 17 (b), when the SSW side use band is TS1 to TS5 and the transmission line side use band is TS21 to TS25, the following data is available. For example, the transmission address 21, the reception address 1, and the bandwidth 5 are set from the high-speed external transmission path 26 to the SSW package 18. Further, there are data such as the transmission address 1, the reception address 21, and the band 5 in the direction from the SSW package 18 to the high-speed external transmission line 26.

In addition to a telephone, a terminal for establishing communication may be a FAX, or a terminal via a TV line or other LAN line.
As a connection configuration between transmission apparatuses, there are generally a relatively simple and regular network configuration such as an open ring configuration shown in FIG. 3A and a ring configuration shown in FIG. In such a case, the construction of a communication path between transmission apparatuses is relatively simple, and a network system that can be determined regularly is obtained.

As a connection configuration of the transmission apparatus, there is a complicated network configuration shown in FIG. In recent large-scale communication networks, there is an increasing tendency to construct such a complex network. In the network configuration of FIG. 4, when a communication path is established between the transmission apparatus C station 41 and the transmission apparatus G station 47, a plurality of communication paths can be established.
That is, there is one path of transmission apparatus C station 41 -transmission apparatus B station 42 -transmission apparatus A station 43 -transmission apparatus D station 44 -transmission apparatus G station 47. Further, there is another path of transmission device C station 41 -transmission device F station 46 -transmission device H station 48 -transmission device G station 47. Further, there is another path of transmission apparatus C station 41 -transmission apparatus F station 46 -transmission apparatus E station 45 -transmission apparatus D station 44 -transmission apparatus G station 47. There are also other communication paths.

  Which communication path is used as a main path and which communication path is used as a backup path is arbitrary, but can be determined by characteristics required for the communication path. For the purpose of securing a safer and more reliable communication path, the main path and the backup path are paths (communication paths) so as to select different transmission apparatuses and different transmission paths (transmission routes) as much as possible. ) Build. In other words, when a communication failure occurs in a part of one transmission path, if the backup path is also a transmission path that uses a part of the failure, even if it is switched to the backup path, the communication failure is avoided. I can't. However, in a backup transmission path constructed via a completely different transmission device and a different transmission route, it does not go through the location where the failure occurred, so by switching to the backup path (backup route), Communication can be secured.

  For the purpose of extremely high-speed communication, the route with the fastest communication speed is selected from the plurality of communication routes configured between the transmission device C station 41 and the transmission device G station 47. It is also possible to use a route with the second highest communication speed as a backup route. That is, the physical conditions such as the transmission distance, the size of the transmission device, and the switch operating speed may be different between the communication paths, so that the transmission device C station 41 and the transmission device G station 47 may differ depending on the transmission path through which the communication routes pass. This is because there may be a difference in the communication time.

  Next, the path setting will be specifically described using the conceptual diagram of the transmission path and port shown in FIG. 5 and the transmission path definition data shown in FIG. In FIG. 5, the transmission apparatus A station 51 communicates with the transmission apparatus B station 52. The transmission apparatus B station 52 communicates with the transmission apparatus C station 53. A communication path from the transmission apparatus A station 51 to the transmission apparatus B station 52 is a transmission path 1 (54), and a communication path from the transmission apparatus B station 52 to the transmission apparatus A station 51 is a transmission path 4 (57). A communication path from the transmission apparatus B station 52 to the transmission apparatus C station 53 is a transmission path 2 (55), and a communication path from the transmission apparatus C station 53 to the transmission apparatus B station 52 is a transmission path 3 (56). .

Further, the transmission apparatus A station 51 allocates and uses port 9 (58) for communication with the transmission apparatus B station 52. The transmission apparatus B station 52 allocates and uses port 8 (59) for communication with the transmission apparatus A station, and allocates and uses port 9 (5a) for communication with the transmission apparatus C station. Further, the transmission apparatus C station 53 allocates and uses port 8 (5b) for communication with the transmission apparatus B station 52.
In this way, the connection name of each transmission path between the transmission apparatuses is defined, each transmission apparatus and each transmission path are distinguished and recognized, and the transmission path can be individually specified. Here, since this is used as transmission line definition data, a table (list) as shown in FIG. 6 is created using this definition. In FIG. 6, a transmission path starting from transmission apparatus A station 51 and ending at transmission apparatus B station 52 is defined as transmission path 1 (54), and port 9 (58) is assigned to transmission apparatus A station 51 to transmission apparatus B. Port 8 (59) is assigned to station 52. Also, the transmission path starting from the transmission apparatus B station 52 and ending at the transmission apparatus C station 53 is the transmission path 2 (55), and the port 9 (5a) is assigned to the transmission apparatus B station 52. Port 8 (5b) is assigned to.

  Further, a transmission path starting from the transmission apparatus C station 53 and ending at the transmission apparatus B station 52 is defined as a transmission path 3 (56), and a port 8 (5b) is assigned to the transmission apparatus C station 53 to transmit the transmission apparatus B station 52. Assign port 9 (5a). A transmission path starting from the transmission apparatus B station 52 and ending at the transmission apparatus A station 51 is defined as a transmission path 4 (57), and a port 8 (59) is assigned to the transmission apparatus B station 52 to transmit the transmission apparatus A station 51. Assign port 9 (58). In this way, transmission lines are defined for all transmission lines. This definition data is held as a transmission line database in a calculation device such as a controller connected to the transmission device or a computer serving as a control device.

  Next, a path configuration between transmission apparatuses necessary for communication between terminal packages will be considered. At this time, since the start point and the end point are defined for each transmission path defined in FIG. 6, the transmission path is constructed in consideration of the vector (or directionality) between the transmission apparatuses that want to construct the path route. A plurality of routes are selected in the order of communication paths from the transmission paths 1 to 4 shown in the transmission path definition data 6. Further, in this figure, a case of a regular simple route (opening) is shown in order to simplify the explanation. However, a plurality of spare routes are provided so that a plurality of communication paths can be constructed. It is preferable to construct in advance.

  7 shows a conceptual diagram of transmission paths and ports in the case of a complex network, and FIG. 8 shows transmission path definition data in the case of a complex network.

The station 77 and the transmission apparatus H are composed of eight transmission apparatuses of the station 78, and constitute a complex network having a plurality of transmission paths.

  In this figure, the terminal package is not particularly shown. That is, in creating the transmission path definition data, the terminal package is added to or deleted from any transmission device, or the transmission device is added to or deleted from any position. For each transmission path between all the transmission apparatuses, it is preferable to define a transmission path individually to make a table. However, when there is a transmission line that is not clearly used, it is preferable to create a transmission line definition table that is not included in the transmission line definition data, because unnecessary data enlargement can be prevented. Although not shown, an arithmetic processing unit such as a personal computer that holds transmission path definition data and the like and performs the below-described pass route processing is connected to the network system.

  In FIG. 7, no transmission path is defined between the transmission device E station 75 and the transmission device G station 77. In FIG. 7, the transmission path between them is not described because the physical wiring is not actually installed between the transmission device E station 75 and the transmission device G station 77 or is used even if it is installed. This is the case when it is not possible or not expected to be used at all in the future. If the transmission line can be used at any time in the future, or is expected to be used, the transmission line definition data is conditionally used as transmission line data that becomes usable after that. Is preferably included.

  Here, the transmission path from the transmission apparatus A station 71 to the transmission apparatus B station 72 is the transmission path 1, and the transmission path from the transmission apparatus B station 72 to the transmission apparatus A station 71 is the transmission path 20.

  The transmission path from the transmission apparatus F station 76 to the transmission apparatus H station 78 is the transmission path 4, and the transmission path from the transmission apparatus H station 78 to the transmission apparatus F station 76 is the transmission path 17. The transmission path from the transmission apparatus H station 78 to the transmission apparatus G station 77 is the transmission path 5, and the transmission path from the transmission apparatus G station 77 to the transmission apparatus H station 78 is the transmission path 16. The transmission path from the transmission apparatus G station 77 to the transmission apparatus D station 74 is the transmission path 6, and the transmission path from the transmission apparatus D station 74 to the transmission apparatus G station 77 is the transmission path 15.

  The transmission path from the transmission apparatus D station 74 to the transmission apparatus A station 71 is the transmission path 7, and the transmission path from the transmission apparatus A station 71 to the transmission apparatus D station 74 is the transmission path 14. The transmission path from the transmission apparatus B station 72 to the transmission apparatus E station 75 is the transmission path 8, and the transmission path from the transmission apparatus E station 75 to the transmission apparatus B station 72 is the transmission path 13. The transmission path from the transmission apparatus D station 74 to the transmission apparatus E station 75 is the transmission path 9, and the transmission path from the transmission apparatus E station 75 to the transmission apparatus D station 74 is the transmission path 12. The transmission path from the transmission apparatus E station 75 to the transmission apparatus F station 76 is the transmission path 10, and the transmission path from the transmission apparatus F station 76 to the transmission apparatus E station 75 is the transmission path 11.

  In this way, the transmission path is defined for all transmission paths of the network system. In addition, as shown in FIG. 8, in defining each transmission path, not only the start and end stations of the transmission apparatus but also the allocation of the transmission path package port to be used for each transmission path is individually defined. To do. By defining the transmission path package port, a specific switch setting in the transmission apparatus when one transmission path is selected is determined.

  For example, in FIG. 8, the transmission path 1 is a transmission path from the transmission apparatus A station to the transmission apparatus B station. In this transmission path 1, the A station uses the port 9 terminal, and the B station is the port. Use 8 terminals. With this definition, when the transmission path 1 is used, the A station can communicate using the port 9 terminal and the B station using the port 8 terminal to establish a communication path with the B station. , SSW and TSW in the B station are set as switches.

7 and 8 are preferably stored in an arithmetic processing unit such as a personal computer. This arithmetic processing unit can transmit control commands for necessary switch settings in a lump by connecting to the transmission unit.
Next, a configuration example of the route shown in FIG. 9 will be described. In FIG. 9, a telephone 90 and a telephone 91 are connected to a transmission apparatus C station 92 and a transmission apparatus G station 93, respectively. Accordingly, a pass route is set between the transmission apparatus C station 92 and the transmission apparatus G station 93.

  FIG. 10 shows three examples of the route.

Is done.
Further, the pass route 3 is connected from the transmission apparatus C station 92 to the transmission apparatus G station 93 through the transmission path 19 -transmission path 8 -transmission path 12 -transmission path 15. In addition, serial numbers are assigned to the transmission paths in order from the transmission apparatus C station 92, so that a communication path is secured from the transmission apparatus C station 92 to the transmission apparatus G station 93 via the transmission paths in the order of serial numbers. Is done.

Here, three examples of the route are shown, but other types of route may be used, and any number of routes may be set. In complex network configurations, many pass-throughs can be set. In addition, since various pass route variations are possible as many pass routes are set, various unexpected situations can be dealt with.
Further, by storing the features in association with each pass route, it is possible to quickly select the pass route that matches the characteristics required for communication when selecting the pass route. For example, pass route 1 has a very high communication speed, pass route 2 has the same communication speed but follows a different original route, pass route 3 has a part of the route being a pass route. A feature such as passing through a transmission apparatus that is overlapped with 1 but will be expanded in the future is described.

As a result, when a failure occurs when using the route 1 and the location of the failure is unknown, the communication can be reliably ensured by switching to the route 2. In addition, it is possible to easily prepare for future terminal expansion by switching to the pass route 3 during maintenance of the pass route 1.
On the other hand, in an actual network configuration, the reliability of the network system configuration itself has improved remarkably with the advancement of technology, so usually two or three pass routes are routed through different transmission paths. It is preferable to set so as to pass through. This is because, even if an unnecessarily large number of pass-throughs are set and held, it is useless if there is no use. However, depending on the characteristics required for the network system, it may be necessary to frequently change the path route by adding or removing each station of the transmission equipment or laying work such as maintenance. is assumed. In such a case, it is preferable to set a large number of pass routes that are expected to be necessary. If two pass routes are set and one is the main route and the other is the backup route, the choice is either the main route or the backup route. Route setting selection is preferred because it is the simplest and easiest.

  In this way, by defining a plurality of pass routes to be used in advance, the change process when the pass route needs to be changed can be performed only by selecting the pass number 1 to 3. . Therefore, the setting change process at the time of the pass route change can be performed remarkably easily and quickly. The transmission path defining data and the pass-through data are stored in an arithmetic processing unit such as a personal computer and connected to a network. Thus, by selecting one pass route on the personal computer, the transmission device and port used for that pass route are automatically searched and read out, and the port of the transmission device is handled in the order of transmission. Each switch can be set.

  Next, a procedure for setting an initial communication path will be described with reference to FIG. As this premise, the pass routes 1 to 3 described in FIG. 10 are defined in advance. This is a procedure for establishing communication between the transmission device C station 111 and the transmission device G station 112 of FIG. 11 via the relay station B station 113, the A station 114, and the D station 115. First, in an arithmetic processing unit such as a personal computer, transmission path definition data and pass route definition are set in advance. Then, the terminal package of the transmission apparatus C station 111 is selected as the starting point (operation count 1). Next, the terminal package of the transmission apparatus G station 112 is selected as the end point (operation count 2). Subsequently, pass route 1 (116) is selected (number of operations 3). Thus, actual setting data is automatically created (operation count 4).

  FIG. 12 shows a comparison of creation of setting data when the number of operations is four. That is, the relay station B station 113, the A station 114, and the D station 115, which are determined in advance as the path route, from the path route data of the path route 1 (116), and the transmission path package points to be allocated and used. -SW search and SW section data creation through the path setting data can be automatically performed in order.

  That is, the SSW setting data creation of the transmission apparatus C station 111 that has been performed manually (operation 3), the transmission path (port 8) of the transmission apparatus C station 111, and TSW setting data creation (operation 4). . Also, transmission line (port 9) TSW setting data creation of relay station B station 113 (operation 5), SSW data creation of relay station B station 113 (operation 6), transmission of relay station B station 113 Road (port 8) TSW setting data creation (operation 7). Also, transmission path (port 9) TSW setting data creation of relay station A station 114 (operation 8), SSW data creation of relay station A station 114 (operation 9), transmission of relay station A station 114 Road (port 8) TSW setting data creation (operation 10). Also, transmission path (port 9) TSW setting data creation of relay station D station 115 (operation 11), SSW data creation of relay station D station 115 (operation 12), transmission of relay station D station 115 Road (port 8) TSW setting data creation (operation 13). In addition, the transmission path (9) TSW data creation (operation 14) of the transmission apparatus G station 112 and the SSW data creation of the transmission apparatus G station 112 are all automatically performed by batch processing. Can be created.

FIG. 17 shows an example of a pre-preparation flowchart for path setting according to this embodiment.
(Step 170) First, it is assumed that a communication network system has been constructed. The communication network system includes a plurality of transmission devices (including repeaters, terminal packages, and SWs) and a plurality of transmission paths. This network may include not only a simple open ring or ring configuration but also a matrix, mesh, three-dimensional matrix, or other complex network. The transmission path may include not only an electric communication line but also a LAN, an optical line, a power communication line, and a wireless line.

In addition, as a processing unit connected to the network, a personal computer including a storage device is required for the network system. If such a network is constructed, the process proceeds to the next step 171.
(Step 171) Transmission path definition data is created for the transmission path between the transmission apparatuses. The transmission path definition data determines the transmission direction from the transmission apparatus to another transmission apparatus, determines the port to be used, and assigns an identification number to the transmission path. The transmission path definition is preferably defined for all transmission paths in the network system. This is because the selection range of the transmission line is widened in the later pass route configuration.

  However, some transmission lines may be physically disconnected due to a failure or the like, may not be usable, or may be laid. Therefore, only the currently available transmission path may be defined. In addition, transmission path definition data may be created for transmission paths that can be used in the future with a condition that they are used after the availability date. If transmission path definition data can be created, the process proceeds to the next step 172.

  (Step 172) Next, a terminal package for communication is selected and determined. This is because the communication route is secured so that the communication can be established between the terminal packages, and a specific candidate for the route route cannot be determined unless the position of the terminal package is determined. However, when there is a possibility of communication between all the transmission devices, that is, it is unclear which transmission device the terminal package is arranged, or the terminal package is allocated to which transmission device. Even in the case where communication is desired, if it is desired to secure communication, the next step 173 may set a pass route for all transmission apparatuses.

  (Step 173) In principle, a plurality of path routes are set between the transmission apparatuses related to the determined two terminal packages. Which is the main route and how many spare routes are created is arbitrary. The path route assigns a serial number for each transmission path in order from one terminal package, describes the transmission path identification symbol used for each serial number, and routes to the other one terminal package. Describe. In this way, a plurality of route routes are created and assigned with a route number to form a list, which is used as the route data.

  (Step 174) The created transmission path definition data and pass route data are stored in a storage device in the SW control device of the transmission device such as a personal computer. As a result, when an actual path is set at a later date, by selecting one path number from a list of path routes corresponding to the terminal packages to be communicated, transmission used for that path The device, transmission path, and port are read from the storage device. Then, according to the read data, SW setting data of each transmission apparatus is created so as to be a transmission path and a port to be used.

Next, the initial route setting operation shown in FIG. 18 will be described. As a premise of this, it is necessary that the transmission path definition data and the pass-through data are created by the advance preparation shown in FIG. 17 and stored in the arithmetic processing unit.
(Step 180) One terminal package is selected as a starting point for communication. If the starting point is determined, the process proceeds to step 181.

(Step 181) One terminal package is selected as an end point for communication. If the end point has been determined, the process proceeds to step 182.
(Step 182) A list of paths corresponding to the terminal package that is the determined start point and end point is displayed. That is, the path route route includes the route data having the same start point and end point as the determined start point and end point, and the determined start point and end point from the plurality of pass route data stored in the storage device. The pass route to be displayed may be displayed as a list. Here, the start point and the end point can be transmission apparatus identification symbols.

  Also, in the case of a pass route that includes the start point and the end point, the display process is performed in consideration of the fact that even a pass route that formally includes the start point and the end point cannot be used if the direction of the vector is different. . That is, in the path route selection process from the start point to the end point, the reverse route route from the end point to the start point is processed separately. If the pass list is displayed, the process proceeds to the next step 183.

  (Step 183) One path route that matches the target communication characteristics is selected from the list displayed. Therefore, at the time of displaying a list of passwords, a comment or the like describing the characteristics of the password may be displayed in association with each password. Such a comment is easily referred to when selecting a route, so that an accurate, optimal and quick selection operation can be easily realized. For example, the display comment may be a fast and slow communication speed, a route safety, a new or old communication route, characteristics of a relay transmission device, a density of communication density, a transmission distance, and the like. The selection of the pass route can be performed by selecting the assigned pass route number, and the process proceeds to the next step 184.

  (Step 184) The determination of the pass route means the determination of the transmission device on the route defined in advance as the pass route and the port number of each transmission device. In other words, since the path number is determined, the route to be used, the transmission device on the route, the port number of the transmission device, and the order thereof are determined, so that the SW configuration for this configuration can be determined. Become. The arithmetic processing for this is performed by an arithmetic device such as a personal computer. Note that the SW section includes both SW of the SSW package and the TSW package. If SW setting data can be created, the process proceeds to step 185.

  (Step 185) The arithmetic unit transmits the SW setting data created in Step 184 to the network. Usually, an arithmetic device such as a personal computer is included in a part of a communication network system and is connected to a predetermined position of the network. Therefore, an SW setting command is output from the arithmetic unit to each related transmission device. The transmission apparatus that has received the command controls and sets the SW unit according to the command in the order of the network path. For this reason, each transmission device has its own SW control device that controls its own SW unit.

(Step 186) In the transmission apparatus corresponding to the order of the network path, SW setting is performed according to the command. That is, when the selected route is, for example, route 2 comprising transmission path 3 -transmission path 4 -transmission path 5 in FIG. 10, transmission apparatus C station 92, relay station F station, relay station H station The SW unit of each transmission device is set in the order of the transmission device G station 93.
That is, in this embodiment, all transmission paths are defined in advance, and a plurality of path routes are set in advance using the transmission path definition. Therefore, when setting or changing the actual path, only the selection of the path route is performed, and each transmission device, relay station, or port used for the automatically selected path route is searched and read. SW setting data is automatically created. For this reason, even when the communication route is changed, it is possible to create route change data only by selecting the number of the route, and each individual transmission route is considered and the communication route is supported for each transmission device. There is no need to manually set the setting data of each switch. Therefore, setting mistakes can be reduced, and rapid and accurate path route setting can be performed.

In addition, when the path route is set as only the second route route of the main route and the backup route, it is set to automatically change to the backup route when a problem occurs in communication through the main route. Is also possible.
(Embodiment 2)
Next, the path setting operation when adding relay stations will be described with reference to FIGS. 13 and 14. FIG. FIG. 13 is a path diagram in the case where the transmission apparatus I station 131 is added as a relay station. FIG. 14 is a path reconstruction procedure diagram at the time of expansion.

  In FIG. 13, a new relay station I station 131 is added between the relay station H station 130 and the relay station G station 132. The added relay station I station 131 communicates with the relay station H station 130 on the new transmission path 22 using the port 8. Further, the added relay station I station 131 communicates with the relay station G station 132 on the new transmission path 21 using the port 9. Further, the transmission path 5 that is output from the relay station H station 130 to the relay station G station 132 before the extension is used as the transmission path 5 that is output from the relay station H station 130 to the newly added relay station I station 131 as it is. . Further, the transmission path 16 that is output from the relay station G station 132 to the relay station H station 130 before the expansion is used as it is as the transmission path 16 that is output from the relay station G station 132 to the newly added relay station I station 131. .

  Therefore, the transmission path definition data is changed as follows. That is, the transmission path 5 before the extension is port 9 of the relay station H station 130 to port 8 of the relay station G station 132. The added transmission path 5 is port 9 of the relay station H station 130 and port 8 of the relay station I station 131. Also, the port 9 of the relay station I station 131 and the port 8 of the relay station G station 132 are defined as a new transmission path 21. As a result, the transmission path from the relay station H130 before expansion to the relay station G station 132 passes through the relay station I station 131 after expansion, and the new relay station H130-relay station I station 131-relay station G station 132 is added. It can be defined as a simple route.

  Further, the transmission line 16 before the expansion is the port 8 of the relay station G station 132 and the port 9 of the relay station H station 130. The added transmission line 16 becomes port 8 of the relay station G station 132 and port 9 of the relay station I station 131. Also, the port 8 of the relay station I station 131 and the port 9 of the relay station H station 130 are defined as a new transmission path 22. As a result, the transmission path from the relay station G station 132 before the extension to the relay station H station 130 passes through the relay station I station 131 after the extension, and the relay station G132-the relay station I station 131-the relay station H station 130. It can be defined as a new route.

  Along with this, the data of pass route 2 (134) is also changed as follows. In other words, pass route 2 (134) before expansion is transmission path 3-transmission path 4-transmission path 5. On the other hand, the pass route 2 (134) after the expansion becomes a transmission path 3-transmission path 4-transmission path 5-transmission path 21. In other words, the transmission path 5 before expansion is changed so that it is divided into the transmission path 5 and the transmission path 21 by expansion. This corresponds to the fact that between the transmission apparatus H station 130 and the G station 132 requires two transmission lines from one transmission line of the transmission line 5 to the transmission line 5 and the transmission line 21 as described above. .

  In this case, the procedure for reconstructing the path setting data is only two operations as shown in FIG. That is, the path change is selected in the arithmetic processing of a personal computer or the like (number of operations 1). Next, as a resetting operation, the relay station F station 133, the H station 130, and the I station 131 are searched from the path route data of the path route 2 (134), and the transmission path package port configured is searched. A search is performed to automatically search for a port and SW section through which path setting data is routed and to create SW section data (operation count 2). The arithmetic processing unit is connected to the network system, and sequentially instructs each transmission device using the created SW unit setting data as the SW unit control signal.

In other words, in this embodiment, all transmission paths are defined in advance, and a plurality of path routes are set using the transmission path definition. Each transmission device, relay station, and its SW setting data are automatically created only by defining the transmission path and changing the route data with the preceding and following repeaters. This makes it possible to create route change data even when the communication route is changed, examine all communication routes individually one by one, and manually set the setting data of each switch corresponding to the communication route for each transmission device. It is not necessary to set in. Therefore, setting mistakes can be reduced, and rapid and accurate path route setting can be performed. In this case, it is very easy to change the throughput data by simply changing one transmission path 5 to two transmission paths 5 and 21.
(Embodiment 3)
Next, the path setting operation when the relay station is removed will be described with reference to FIGS. 15 and 16. FIG. FIG. 15 is a path diagram when the transmission apparatus F station 150 is removed as a relay station. FIG. 16 is a path reconstruction procedure diagram at the time of reduction.

  In FIG. 15, the reduced station F station 150 is installed between the transmission apparatus C station 152 and the transmission apparatus H station 151. The data of the transmission line is changed as follows by the reduction. That is, the transmission path 3 before the reduction is the port 9 of the transmission apparatus C station 152 and the port 8 of the transmission apparatus F station 150. Further, the transmission path 4 before the reduction is the port 9 of the transmission apparatus F station 150 and the port 8 of the transmission apparatus H station 151. On the other hand, the transmission path after the reduction is directly connected to port 9 of the transmission apparatus C station 152 to port 8 of the transmission apparatus H station 151 due to the disappearance of the transmission apparatus F station 150. The transmission line 3 is defined as a non-transmission line 3 and disappears.

  Further, the transmission path 17 before the reduction is the port 8 of the transmission apparatus H station 151 and the port 9 of the transmission apparatus F station 150. The transmission path 18 before the reduction is the port 8 of the transmission apparatus F station 150 and the port 9 of the transmission apparatus C station 152. On the other hand, the transmission line after the reduction is directly connected to the port 8 of the transmission apparatus H station 151 to the port 9 of the transmission apparatus C station 152 due to the disappearance of the transmission apparatus F station 150. The transmission line 18 disappears.

That is, in the transmission path definition data, the transmission path 3 is newly defined as port 9 of the transmission apparatus C station 152 -port 8 of the transmission apparatus H station 151, and the transmission path 4 is deleted. Also, in the transmission path definition data, the transmission path 17 is newly defined as port 8 of the transmission apparatus H station 151 -port 9 of the transmission apparatus C station 152, and the transmission path 18 is deleted.
As the transmission apparatus F station 150 is reduced, the throughput data is changed as follows. That is, pass route 2 (154) before the reduction is transmission path 3-transmission path 4-transmission path 5. On the other hand, the pass route 2 (154) after the reduction is a transmission path 3 to a transmission path 5. That is, formally, the two transmission paths 3 and 4 are merged and newly defined as one transmission path 3.

  In this case, the procedure for reconstructing the path setting data is only two operations as shown in FIG. That is, a path change is selected by an arithmetic processing unit such as a personal computer (operation count 1). Next, as a pass route resetting operation, the relay station H station 151 is set between the start point transmission apparatus C station 152 and the end point transmission apparatus G station 153 from the path route data of the pass route 2 (154). Search and search for the configured transmission path package port. In addition, the SW section search and SW section data creation via the path setting data are automatically performed (number of operations twice). The arithmetic processing unit is connected to the network system, and sequentially instructs each transmission device using the created SW unit setting data as the SW unit control signal.

  In other words, in this embodiment, all transmission paths are defined in advance, and a plurality of path routes are set using the transmission path definition. Each transmission device, relay station, and its SW setting data are automatically created simply by defining the transmission path and changing the route data with the relay units before and after the location. For this reason, it is possible to create route change data even when the communication route is changed, examine the communication route individually one by one, and manually set the setting data of each switch corresponding to the communication route for each transmission device. It is not necessary to set. Therefore, setting mistakes can be reduced, and rapid and accurate path route setting can be performed. In this case, it is very easy to change the pass rate data by simply changing the second transmission path 3 and the transmission path 4 to one transmission path 3.

Here, a processing flow in the case where the number of relay stations is increased or decreased will be described with reference to FIG.
(Step 190) First, it is necessary to identify and recognize the positional relationship between the repeaters and transmission devices to be increased or decreased. In this embodiment, it is only necessary to perform update processing in the relationship between the repeater etc. for the increase / decrease installation and the existing transmission apparatus that newly communicates with the repeater etc. for the increase / decrease installation, or no longer communicates, There is no need to make any changes or updates to the transmission lines and paths for other parts. If the position has not been determined or is still under consideration, a specific transmission path or path change / update operation cannot be performed, so the process returns to the start.

(Step 191) It is confirmed whether or not there is a transmission path that passes through or has passed through a repeater or the like related to the increase / decrease setting. If this transmission line does not exist, the repeater or the like related to the increase / decrease does not have any influence on the communication path. Therefore, if there is no transmission path, the process ends here. If there is a transmission path, the process proceeds to the next step 192.
(Step 192) The transmission line definition data is updated between the transmission apparatus related to the transmission line grasped in Step 191 and the repeater related to the increase / decrease setting. Since the specific update content has already been described, it is omitted here. Unlike the prior art, it is not necessary to review all the transmission lines, and it is only necessary to change and update only the related transmission lines. Therefore, the amount of work can be reduced, leading to reductions in operation errors and setting errors. Moreover, it becomes possible to perform a quick change process safely and reliably. If the transmission path definition data can be updated, the process proceeds to step 193.

(Step 193) It is determined whether or not there is a pass route for the increase / decrease setting. Even if there is a transmission path, if there is no route that uses the transmission path, no new change to the throughput data is required, so the processing ends here. If there is a pass route, the process proceeds to step 194.
(Step 194) The pass-through data is updated. Since the specific update contents and the method have already been described, they are omitted here. In this embodiment, only the location relating to the transmission line updated in step 192 needs to be changed and updated, so that the amount of work can be reduced, and problems during updating such as setting mistakes can be reduced. Can do.

(Supplement)
A communication network system control apparatus according to these embodiments includes a transmission apparatus including a plurality of switch units, and a transmission path that connects the transmission apparatuses so that they can communicate with each other. And a storage device that stores transmission line definition data created by associating two transmission apparatuses to be connected and their use ports with each other in consideration of the communication direction.

  As a result, the contents and properties of each transmission path are determined and clarified, and the transmission paths can be managed collectively as transmission path definition data. It is also possible to construct a pass route by displaying transmission path definition data as a list and selecting a transmission path from the list. When considering the route between each transmission device using the transmission line definition data, not only the transmission route that can be adopted as a route building element is clarified, but also the assigned port is used in the transmission device. Since the data includes SW setting information as well, effective transmission line data management can be performed.

In addition, the communication network system control apparatus according to these embodiments preferably includes a plurality of path routes created by a storage device configured by configuring a plurality of transmission paths of transmission path definition data in the order of communication directions. Is stored.
As a result, it is possible to save the trouble of examining the route one by one when the route is reset between the transmission apparatuses or when the route is changed, and the occurrence of a route error can be prevented. That is, since the path route is determined in advance based on the transmission path determined in advance, a transmission path that does not exist in the transmission path definition data stored here or a path route that does not exist in the path path data is This is because no communication path is constructed.

In the communication network system control apparatus according to these embodiments, preferably, a plurality of switch units are configured by a transmission path package and an SSW package, and a plurality of path routes perform communication. A plurality of terminal packages are created for each communication direction.
Therefore, it is possible to construct a hierarchical and superimposing route by switch control including connections and cross-connects in the transmission apparatus. Furthermore, a plurality of pass routes are always provided for a certain communication, which contributes to secure communication safety. In other words, even if a situation in which one communication path cannot be used occurs, it is possible to quickly switch to another backup communication path, so even if an unexpected situation occurs between terminal packages, it is possible to stably Communication can be secured.

It should be noted that it is preferable to create a plurality of pass routes by making the transmission paths and transmission devices through which they pass different as much as possible. That is, even if a communication failure occurs at any location for any reason, changing the pass route to another pass route can reliably avoid the communication failure and ensure communication. It is.
In addition, a transmission line or a route that can be used in the future even though it is not currently usable may be stored in the control device as a transmission line or a route with a stop condition in which the effective timing is set. On the other hand, a transmission path or pass route that can be used at present but cannot be used in the future is stored in the control device as a transmission path or pass route with a release condition in which an expiration date (or expiration date) is set. You may keep it.

  Further, it is preferable that the transmission path definition data is given the characteristics and properties of the transmission path for each transmission path. The characteristics and properties of the transmission line include, for example, the new and old construction date, communication speed, congestion of the line, history of failure, possibility and timing of change such as expansion / reduction, parts used and their manufacturers, It may be a communication error frequency and an error rate. Thus, more accurate processing can be performed by referring to the information during transmission path selection and maintenance.

  Further, it is preferable that the pass route data is given the characteristics and properties of the pass route for each pass route. The characteristics and properties of the route include, for example, the old and new settings, communication speed, congestion, failure history, possibility of change such as expansion / reduction, timing, parts used and their manufacturers. Communication error frequency and error rate, the number of transmission paths that pass through, the number of transmission apparatuses that pass through, the type and characteristics of the transmission apparatuses that pass through, etc. Thus, more accurate processing can be performed by referring to the information at the time of password selection and maintenance.

Also, the communication network system control apparatus according to these embodiments is preferably configured so that, when one pass route is selected from the pass route data, the selected one pass route can be constructed. A command to control and set the switch unit of the transmission device is output to the transmission device.
Thereby, the selected pass route can be reliably constructed. The construction of the path route can be performed at the actual transmission apparatus level by controlling and setting a path setting in the transmission apparatus, typically a switch in the transmission apparatus. Since the switch network control device creates and outputs this switch setting command, it is not necessary to manually create switch control data for each transmission device, and human error can be prevented.

Also, in the communication network system control device, if the transmission device linked to the pass route and its use port are held as data, the relationship between the port, the transmission device, and the transmission path. Therefore, the setting data of the switch unit can be easily created in order of the route. This makes it possible to construct a reliable and reliable pass route that is rapid and reproducible.
The path setting method of the communication network system according to these embodiments is a communication network system including a plurality of transmission devices, a plurality of transmission paths, and an arithmetic processing device, The apparatus includes a SW control device configured by a plurality of SW units and controlling the SW unit, and the arithmetic processing unit includes transmission path definition data for separately defining transmission paths between the transmission apparatuses, and a plurality of transmission path definition data A storage device for storing a plurality of path routes configured by transmission paths, and setting a communication path between the transmission apparatuses by selecting one path route from the plurality of path routes; Set automatically.

As a result, the artificial operation performed when changing or setting the communication path is only the selection of the path route, and a desired path can be set quickly and accurately.
In the communication network system path setting method according to these embodiments, the communication path between the transmission apparatuses is preferably set by controlling a plurality of SW units by the SW control apparatus of the transmission apparatus.

Thereby, for example, an SW unit composed of SSW and TSW is set by the SW control device of the transmission device. In addition, the specific contents of the SW control are instructed from an arithmetic processing unit connected to the communication network system, and the overall balance is controlled under a centralized and centralized management over all communication paths. It is possible to set a good path.
In addition, in the communication network system path setting method according to these embodiments, the communication path between the transmission apparatuses is preferably set by setting the communication path between terminal packages arranged in different transmission apparatuses. is there.

  As a result, terminal packages are provided between different transmission apparatuses, and when a telephone, a facsimile, or an information processing device is connected to the terminal package, for example, a pass can be easily made between the telephones. The communication line can be secured by setting. There is no problem even if the distance between different transmission apparatuses is long or short. The present invention is applicable at least between transmission apparatuses that can be reached via one or a plurality of transmission paths.

  Note that the transmission path may be a transmission path that is preferably provided with physical wiring such as a telephone line. However, it may be a wireless line or the like, and may be a transmission path in the sense of a path that can transmit information and / or a path that has the capability and possibility of transmitting information. For this reason, whether or not a certain path can be said to be a transmission path may depend on a transmission / reception device that transmits information via the path.

  That is, one pass route is completed by vector-summing a plurality of transmission lines as constituent elements. Each transmission path is characterized by different properties, such as different transmission devices connected and different transmission distances. Since a predetermined aggregate of transmission lines having different properties becomes a path route, it can be said that the properties of a certain path route are ultimately determined by the transmission line as a component.

Further, it is preferable that the transmission apparatus to be added is added in a form that interrupts the transmission path between the one transmission apparatus and the other transmission apparatus. In this case, these embodiments can be suitably applied.

  In addition, when a new transmission device is added separately to a location where a transmission line does not exist, instead of an addition on the existing transmission line, a new one generated between the transmission device and the existing transmission device is added. A transmission path may be defined and added to the transmission path definition data. In addition, a new route using a newly defined transmission path can be constructed and added to the route data.

In other words, after creating transmission path definition data, a plurality of path routes can be generated as the path route data to make a choice candidate list. Therefore, it is very easy to compare which pass route should be selected, and this is a clear and user-friendly setting method. Furthermore, if there is no path route that matches the desired path route candidate list in the created list, a sequential vector sum of the transmission paths is constructed based on the transmission path definition data.
