Description

  The present invention relates to a technique for analyzing device information of a data transfer device.

  When transferring data on the network, a data transfer device (hereinafter referred to as a transfer device) such as a router is used. When the data communication path is changed due to a change in the network configuration or a failure of the transfer device, the network administrator or the operator (hereinafter referred to as an operator) issues a command to each IF (interface) of the transfer device. The commands are input in an appropriate order, and the setting information of each IF is changed to bypass or return. Detouring is changing the target transfer device from the active system to the standby system, and the reverse is the reverse.

  This will be described in detail in the network configuration example of FIG. For example, when the backbone router 1 is bypassed, an operator or the like obtains device information including setting information of the OS and each IF from the backbone router 1, and the service execution state (ACT system / SBY system) of the backbone router 1 Understand the type of OS (Operating System).

  First, a procedure manual for inputting an instruction command to each IF is created based on the grasped result. For example, if the backbone router 1 is an OS of the type 0 (ACT type) and the tentative name A, [Procedure 1. Detour processing of IF connected to router 2 for route reflector], [Procedure 2. Detour processing of each IF connected to routers belonging to the same system (system 0) such as core router 3 and access router 4], [Procedure 3. Detouring each IF connected to a router belonging to another system (system 1) such as the core router 5], [Procedure 4. The procedure manual of FIG. 23 is created as “the logical tunnel route IF detour processing set between the core router 1 and the core router 3”.

  After that, in order to realize the detour processing of each procedure in the backbone router 1, after generating command commands for each procedure to change the cost value of each IF larger than the current one, and confirming that there is no setting omission Then, it is sequentially input in the order in the procedure manual via the command line on the OS of the backbone router 1.

“OSPF settings”, [online], [October 10, 2013 search], <URL: http://www.cisco.com/cisco/web/support/JP/docs/WL/OtherWLProducts/WT2700WLSuite/ IG / 002 / iro_cfg.html? Bid = 0900e4b1825296c6>

  However, the type of OS and IF setting method (command grammar for inputting instruction commands, etc.) vary greatly depending on the transfer device, and more IFs are subject to change. It takes a lot of time to define and generate a desired command.

  Also, a series of operations such as grasping the service execution state, grasping the OS type, grasping the command command input order, grasping the command grammar, and finding the new setting value for detouring or detouring are all performed manually. For this reason, the load applied to the worker or the like is very large, and there is a high possibility that an artificial setting error will occur.

  In the above example, if the cost value of all IFs of the basic router 1 should be changed to [60000], for example, the change of the IF connected to the access router 4 is leaked due to human error. In the downstream traffic from the parent area side to the child area side, the communication path between the backbone router 1 and the access router 4 has a minimum cost. Therefore, the traffic is concentrated on the communication path, and further, the access router 4 and other system backbones. An unnecessary reflection path to the router 5 is generated.

  The transfer device analysis information providing server 100 according to the present invention is mainly configured to include three function processing units. This will be outlined in the feature explanatory diagram of FIG.

  One is a device information analysis unit 10. Discrimination information for discriminating specific setting information is set in advance in a schema file, the device information of each transfer device 200 is analyzed using the discrimination information of the schema file, and the specific information extracted by the analysis is analyzed. The setting information is collected and stored in a common device information storage unit 20 which is a general-purpose DB (database) that can be used by any means.

  The discrimination information in the schema file is, for example, OS name determination information, OS version determination information, service information, ACT / SBY determination information, basic information determination rule file, group number determination rule file, and the like. This is information used to analyze the device information of the transfer device 200. Based on the design information of the existing network configuration, it is created in advance by a network administrator who is familiar with the network configuration. Details will be described later.

  As a result, specific setting information is accumulated in, for example, a general general-purpose database of a relational model method (SQL base or the like), so that it can be easily referred to by the command command generation and input unit 40 described later as a variable. It can be used as a data infrastructure for other systems. This makes it possible to use each piece of device information in different data formats for general purposes according to the type of OS. In addition, since the processing does not depend on the type of OS, it is not limited to a transfer device having a specific OS, and has an expandability that can support any transfer device.

  The other is a group information giving unit 30. A group number assigned to each IF in the setting information stored in the device information storage unit 20 in accordance with the name of the IF and its connection destination, etc., and is also used when determining the order in which command commands are input It is characterized by assigning a number.

  As a result, the IFs of the transfer apparatus 200 are automatically grouped, so that the time required for manual grouping can be reduced and human errors such as erroneous grouping can be prevented. Further, it becomes possible for a simple worker who is not a network administrator to be able to input command commands in a group unit in an appropriate order with the same knowledge level as the network administrator.

  The remaining one is an instruction command generation input unit 40. Using the setting information acquired from the device information storage unit 20, an instruction command corresponding to the OS of the predetermined transfer device 200 ′ is generated, the order in which each command command is input to each IF is determined, and the input order is determined. It is characterized in that an instruction command is sequentially input to each IF of the transfer apparatus 200 ′.

  Thereby, an instruction command that conforms to the command grammar of the OS of the transfer apparatus 200 ′ can be automatically generated. In addition, the work content of the worker or the like can be simplified to the process of “selecting a detour or detour return target transfer device”, and the work load on the worker or the like can be reduced.

  As described above, since the three function processing units described so far are provided, the transfer device analysis information providing server 100 absorbs differences in the OS type and IF setting method in each transfer device. Even in this case, an appropriate command command can be input to each IF of the transfer device in an appropriate order, and the setting information of the transfer device can be changed reliably in a short time. Through these effects, it is possible to reduce the load on the operator or the like required to change the setting of the transfer device as a result.

  The OS determination unit 14 has a function of determining OS information (OS type and name, OS version, etc.) of the transfer device 200 from the acquired device information based on an OS determination request from the data analysis unit 12.

  The service information accumulating unit 15 accumulates service information such as a cost value (such as a detour reroute cost value or a detour return normal cost value) according to a service execution state (ACT system or SBY system operation state). It has a function to keep. By using this service information, a cost value set for detouring or returning the transfer device 200 is specified. In addition to such service information, the function of storing for each service the ACT / SBY determination information set by associating the name of the transfer device 200 or the name of the service with the current execution state of the service. Prepare.

  The basic information storage unit 16 has a function of storing, for each OS, a basic information determination rule file used when specifying basic information such as setting information of each IF from device information. By using this rule file, the current setting state set in each IF of the transfer apparatus 200 is specified.

  The group information accumulation unit 17 has a function of accumulating a group number determination rule file used for assigning a group number to which the IF belongs to the IF of the transfer apparatus 200 for each OS or each IF. By using this rule file, the IFs of the transfer apparatus 200 are grouped.

  Next, a function processing unit that implements the command command generation input unit 40 of FIG. 1 will be described. The command command generation input unit 40 includes an individual command generation request reception unit 41, a generalized command information storage unit 42, a generalized command conversion unit 43, an instruction command information storage unit 44, an individual command generation unit 45, This is realized by the individual command transmission unit 46 and the setting result confirmation unit 47.

  The individual command generation request receiving unit 41 has a function of receiving, from the operation management terminal 300, an individual command generation request for generating an individual command for detouring or returning the target transfer device 200 '.

  The generalized command information accumulating unit 42 accumulates generalized command information for converting the content of the command requested by the individual command generation request into a generalized command that can be processed inside the transfer device analysis information providing server 100. It has a function to keep.

  Note that generalized command information and instruction command information to be described later are also created in advance by the network administrator based on the existing network configuration, similarly to the determination information of the schema file described above.

  The generalized command conversion unit 43 has a function of converting the received individual instruction generation request into a generalized command.

  The instruction command information storage unit 44 is a model of a plurality of instruction commands created according to the type of OS (instruction system of instruction commands) and specific instruction contents (reroute / non-reroute) requested by an individual instruction generation request. A function for storing data (template data) is provided.

  The individual instruction generation unit 45 mainly has three functions. One is a function of converting the generalized command into template data (OS group layer command) of an instruction command corresponding to the OS of the target transfer apparatus 200 ′. The other is to generate an instruction command at a throwable level by inserting the setting information of each IF of the transfer device 200 ′ acquired from the device information storage unit 20 into the variable column of the OS group layer command. It is a function. The remaining one is a function for determining the order in which command commands are input based on the procedure manual data created in advance by the network administrator and the group number assigned to each IF.

  The individual command transmission unit 46 has a function of inputting each command command to each IF of the transfer device 200 ′ in order according to the determined input order.

  The setting result confirmation unit 47 uses the setting information set in the transfer device 200 ′ based on the input of the command command as the setting information in the command command (the setting information of the transfer device 200 ′ acquired from the device information storage unit 20). It has a function of determining and detecting whether or not it matches.

  This is the main function of the transfer device analysis information providing server 100. In addition to such a function processing unit, a setting information confirmation unit 51 and an update information notification unit 52 are further provided for the purpose of periodically performing the confirmation process performed by the setting result confirmation unit 47.

  The setting information confirmation unit 51 acquires the current setting information from the transfer device 200 ′ and periodically determines whether or not the setting information of the transfer device 200 ′ stored in the device information storage unit 20 matches. It has a function to detect. In addition, it also has a function of updating the setting information of the transfer device 200 ′ when it does not match.

  The update information notification unit 52 notifies the operation management terminal 300 of the determination result of the setting information confirmation unit 51 and the updated information about the transfer device 200 ′ (the name of the transfer device 200 ′, the name of the IF, etc.) by e-mail or the like. It has a function to do.

  The above is the function of the transfer device analysis information providing server 100. The transfer device analysis information providing server 100 is communicably connected to a plurality of transfer devices 200 arranged on a network and an operation management terminal 300 used by an operator or the like.

  The transfer device 200 is a router whose main purpose is to relay data between different networks. However, the transfer device 200 has a routing function in various other devices that execute data transfer processing on the OS, for example, the OS. A general-purpose server or the like may be used.

  Next, the operation of the transfer device analysis information providing server 100 will be described. This operation is composed of three operations that can be executed independently of each other. One is an operation of analyzing the device information of the designated transfer device 200 and storing it in the device information storage unit 20. The other is an operation of inputting a command command to the transfer device 200 ′ to be bypassed or returned using the device information stored in the device information storage unit 20. The remaining one is an operation of periodically confirming whether or not the content of the input command is actually set in the transfer apparatus 200 '.

  First, the first operation will be described. FIG. 3 is a sequence showing apparatus information analysis and accumulation processing (entire).

  First, when an operator or the like operates the operation management terminal 300 to access the transfer device analysis information providing server 100, a GUI (graphic user interface) screen in FIG. 4 is displayed on the operation management terminal 300 (step S101). ).

  When the operator inputs the name of the target transfer device 200 and the name of the service from the GUI and presses the “execute” button, the operation management terminal 300 analyzes for analyzing the device information of the transfer device 200. The command is transmitted to the transfer device analysis information providing server 100 (step S102).

  Note that a “device list” button is prepared in advance in the GUI of FIG. 4, and the name of the target transfer device is selected by selecting one of a plurality of transfer devices displayed in a superimposed manner when the button is pressed. May be automatically entered in the device name input field.

  Next, in the transfer device analysis information providing server 100, when the device information generation request receiving unit 11 receives an analysis command from the operation management terminal 300, the device information acquisition unit 13 starts from the transfer device 200 with the name included in the analysis command. Device information including setting information of each IF is acquired (step S103).

  Thereafter, the data analysis unit 12 analyzes the device information acquired in cooperation with the OS determination unit 14, the service information storage unit 15, the basic information storage unit 16, and the group information storage unit 17 (step S104), and the analysis result is obtained. The information is stored in the device information storage unit 20 (step S105).

  This is the first overall operation. Subsequently, the operation of step S104 performed by the transfer device analysis information providing server 100 will be described in detail. FIG. 5 is a sequence showing device information analysis and accumulation processing (details).

  First, when the data analysis unit 12 transmits device information to the OS determination unit 14 to request OS determination, the OS determination unit 14 specifies the name and version of the OS from the device information based on the OS determination request. A reply is made (step S201).

  The OS determination unit 14 holds, for example, the OS name determination information in FIG. 6 and the OS version determination information in FIG. 7 in which the determination condition is defined for each OS, and the OS name and version corresponding to the condition are stored. Identify.

  Next, the data analysis unit 12 uses the service information of the service information storage unit 15 and the information for ACT / SBY determination, and uses a reroute cost value or a detour return for detouring to be set in each IF of the target transfer apparatus 200. A normal cost value or the like is specified (step S202).

  In the service information storage unit 15, for example, service information of FIG. 8 and ACT / SBY determination information of FIG. 9 are prepared in advance. First, using the ACT / SBY determination information, the current service execution state of the transfer device 200 is specified from the name of the transfer device 200 and the service name input at the operation management terminal 300. Thereafter, using the service information, the normal cost value and the reroute cost value corresponding to the execution state of the specified service in the service with the previous name are specified.

  Next, the data analysis unit 12 uses the OS name and the like specified in step S201 and the basic information determination rule file of the basic information storage unit 16 to determine the name and IP address of each IF of the transfer device 200 from the device information. Information or the like is specified (step S203).

  In the basic information storage unit 16, for example, a basic information determination rule file shown in FIG. 10 is prepared in advance. Using the basic information determination rule file corresponding to the corresponding OS, each setting information defined in the rule column in the rule file is specified from the device information. For example, it is specified by acquiring a character string that satisfies the condition of “description” or less under the syntax of “BaseLayer” (“^” means there is no space at the beginning of the line) interface ”. As a result of this processing, for example, IF setting information as shown in FIG. 11 is specified.

  Next, the data analysis unit 12 specifies each IF group of the transfer apparatus 200 using the setting information of each IF specified in step S203 and the group information determination rule file of the group information storage unit 17, respectively. The identified group number is assigned to each IF (step S204).

  In the group information storage unit 17, for example, a group information determination rule file of FIG. 12 is prepared in advance. “Result (group number)” corresponding to “Condition (condition)” is assigned to each IF identified in the previous step. For example, if the specified “Description” is “description test” and “Interface” is “interface 0/0/0/0”, “Group 5” is assigned to the IF of the name.

  The group number is given a different number depending on the name of the IF and its connection destination, and the same group number is given to a plurality of IFs having the same “Condition (condition)”.

  Here, for use in the following description, in the backbone router 1 of FIG. 22, “5” for the IF connected to the router 2 for the route reflector, and two IFs connected to the core router 3 and the access router 4. It is assumed that a group number of “2” is assigned, “1” is assigned to two IFs connected to the trunk router 5, and “4” is assigned to a logical tunnel route IF.

  Finally, the data analysis unit 12 acquires current date and time information from a time management unit (not shown in FIG. 2) of the transfer device analysis information providing server 100, an NTP server, or the like (step S205), and sends it to the target transfer device 200. The unique ID allocated to the device information is acquired from the device information storage unit 20 (step S206), and all the setting information acquired in the process so far is registered in each field in the device information storage unit 20 (step S207). ).

  This is the first detailed operation. As a result of the first processing, as illustrated in FIG. 13, the device information of the transfer device 200 is stored in the device information storage unit 20 in a data format that can be used for general purposes.

  Next, the second operation will be described. FIG. 14 is a sequence showing instruction command input processing (entire).

  First, when an operator or the like operates the operation management terminal 300 to access the transfer device analysis information providing server 100, the GUI screen of FIG. 15 is displayed on the operation management terminal 300 (step S301).

  Then, when the operator selects a desired process for the target transfer device 200 ′ from the GUI and presses the “YES” button, the operation management terminal 300 performs an individual operation to bypass or return the transfer device 200 ′. The command generation request is transmitted to the transfer device analysis information providing server 100 (step S302).

  Next, the transfer device analysis information providing server 100 generates an individual command (command command group) for each IF of the target transfer device 200 ′ based on the received individual command generation request (step S303), and the transfer device 200 ′. (Step S304).

  This is the second overall operation. Subsequently, the operations of steps S303 and S304 performed by the transfer device analysis information providing server 100 will be described in detail. FIG. 16 is a sequence showing instruction command input processing (details). FIG. 17 is a reference diagram at the time of the detailed description.

  First, when the individual command generation request receiving unit 41 receives an individual command generation request from the operation management terminal 300 (step S401), the transfer device analysis information providing server 100 starts processing based on the request. An instruction conversion query for converting to a generalized command is issued (step S402).

  Next, when the generalized command conversion unit 43 receives the instruction conversion query, the generalized command information stored in the generalized command information storage unit 42 is used to convert the individual command specified in the individual command generation request into a generalized command. Conversion is performed (step S403).

  In the generalized command information storage unit 42, for example, generalized command information of FIG. 18 is prepared in advance. It is converted into a generalized command corresponding to the processing content specified by the GUI.

  Thereafter, an OS group layer query is issued to convert the generalized command into an OS group layer command that can be commanded by the OS of the target transfer apparatus 200 '(step S404).

  Next, when the individual instruction generation unit 45 receives the OS group layer query, first, the generalized command is converted into an OS group layer command using the instruction command information in the instruction command information storage unit 44 (step S405). .

  In the command command information storage unit 44, for example, the command command information of FIG. 19 is prepared in advance. It is converted into an OS group layer command that matches the name of the designated transfer device 200 'and the contents of the generalized command.

  Subsequently, the individual command generation unit 45 uses the device information of the transfer device 200 ′ stored in the device information storage unit 20 to use OS group layer command variables (* / *, [Reroute], [ RevReroute] etc.), the command command group to be input to all IFs of the transfer device 200 ′ is generated (step S406).

  For example, when the transfer device 200 ′ is bypassed, the reroute cost value of [Reroute_cost] illustrated in FIG. 13 is input to [Reroute] in FIG. 19. On the other hand, when detouring the transfer apparatus 200 ', the normal cost value of [Normal] shown in FIG. 13 is input to [RevReroute] in FIG.

  Subsequently, the individual instruction generation unit 45 generates insertion order data in which the group numbers are written in order from the top in accordance with the procedure defined by the procedure manual data (step S407).

  For example, in the case of the procedure manual of FIG. 23, the input order data of the group numbers ordered from the top as shown in FIG. 20 is generated. Note that the command commands of the respective group numbers may be input in order based on the procedure defined by the procedure manual data without generating the input sequence data.

  Thereafter, the individual instruction generation unit 45 issues an individual instruction transmission query for inputting each instruction command to the IF of each group in accordance with the order of the input order data (step S408).

  Next, when receiving the individual command transmission query, the individual command transmission unit 46 sequentially inputs command commands of each group to each IF of the transfer apparatus 200 ′ according to the order specified by the query (step S 409).

  In the case of FIG. 20, first, an instruction command is input to the IF assigned with the group number “5”, and then each instruction command is input to each IF assigned with the group number “2”. input. It inputs simultaneously with respect to several IF (IF group with the same connection destination) which belongs to the same group to which the same group number was provided.

  Finally, the setting result confirmation unit 47 acquires the setting information from the transfer device 200 ′, and inputs the current setting information set in the transfer device 200 ′ based on the input of the command command and the transfer device 200 ′ in step S409. A difference from the set information is detected (step S410).

  Even if an instruction command is input to each IF of the transfer apparatus 200 ′, settings based on the instruction command may not be reflected inside the transfer apparatus 200 ′ due to the influence of an operation failure of the OS. Therefore, step S410 is executed.

  If there is no difference, it is assumed that the cost value of each IF of the transfer apparatus 200 ′ has been changed through the instruction command, and the process ends. On the other hand, if there is a difference, the cost value has not been changed as expected by the worker or the like, and therefore the setting result confirmation unit 47 indicates that the process for the target transfer device 200 ′ is NG. Notify In this case, the operator requests processing again from the operation management terminal 300.

  This is the second detailed operation.

  Next, the third operation will be described. FIG. 21 is a flowchart showing a setting state confirmation process.

  First, the setting information confirmation unit 51 determines whether the current time is, for example, 2:00 am (step S501).

  Then, at that time, the setting information confirmation unit 51 acquires each setting information from all the transfer devices 200 ′ that have been detoured or returned, and the current setting information of each of the transfer devices 200 ′, Differences from the setting information of each transfer device 200 ′ stored in the device information storage unit 20 are detected (steps S502 and S503).

  Next, when there is a difference between the setting information, the setting information confirmation unit 51 receives the individual command generation request in order to match the setting information of the transfer device 200 ′ having the difference with the setting information of the device information storage unit 20. An individual command generation request is transmitted to the unit 41 (step S504).

  Accordingly, steps S401 to S410 in FIG. 16 are executed again, so that the setting information of the transfer device 200 'is updated.

  Next, the update information notification unit 52 notifies the operation management terminal 300 of the detection result of step S502, the name of the updated transfer device 200 ', and the like (step S505).

  After step S505, the process returns to step S501, and steps S501 to S505 are repeatedly executed at regular time intervals. Similarly, when the result of the determination in step S501 or step S503 is NO, the process returns to step S501.

  This is the third detailed operation. The function and operation of the transfer device analysis information providing server 100 have been described above.

  As described above, according to the present embodiment, specific setting information is extracted from the device information of the transfer device 200 using the determination information for determining specific setting information, and device information storage that can be used by any means Since the setting information is stored in the unit 20, the specific setting information can be used for general purposes, and the load on the operator or the like required to change the setting of the target transfer apparatus 200 ′ using the setting information can be reduced.

  In the present embodiment, as a method for detouring or detouring the transfer apparatus 200, a method for changing the cost value of OSPF (Open Shortest Path First) has been described as an example. In addition, the transfer device 200 is bypassed by changing “values of various parameters set for each transfer device to control traffic” such as local preference of BGP (Border Gateway Protocol). Or you may make it return. That is, any parameter value for traffic control may be used, and the same effect can be obtained by applying the same operation with the same function as in the present embodiment.

  Finally, the transfer device analysis information providing server 100 described in this embodiment can be realized by a computer having a memory and a CPU. It is also possible to construct each operation of the transfer device analysis information providing server 100 as a program, install it on a computer and execute it, or distribute it via a communication network.
