Description

  The present invention provides a data setting system for realizing priority control of data to be input in a data setting system having a priority function for setting various data for providing services input from a higher system to a lower system, The present invention relates to an apparatus, a method thereof, and a program using the apparatus.

  In recent years, with the spread of IP networks, IP services represented by VoIP have been diversified. Servers that provide services are also becoming more complex, and network management methods for data setting and monitoring for multi-vendors or multi-servers are indispensable. However, even in such a diversified environment, the provision of services to users requires immediateness.

  As a conventional data setting method, for example, there is a data setting method such as JP-A-5-68085 (see Patent Document 1). In these prior arts, as shown in FIG. 2, the setting data from the host system 31 is not distinguished between those requiring real-time characteristics and those having a grace period, and in a sequential flow style. The lower system 34 was reached. That is, the plurality of data set in the host system 31 are mixed data 32 (1, 2, 3, 3) even if priority (high) (medium) (low) is added to each data. 4, 5), and the system 33 performs sequential processing (order 1, 2, 3, 4) in the arrival order from the higher system 31 and sends it to the lower system 34. It was.

  In this way, in the conventional technique, data with high priority and low data are mixed and processed. For example, if an emergency process such as an operator is executed while a large amount of data is being input, there is a waiting time. Occurs, and the actual service cannot be started until a notification of completion of setting the data group is obtained. Also, depending on the amount of traffic, it becomes congested and there is a possibility of connection timeout. However, in the present day when immediacy is required, the conventional system environment is not convenient, and it is possible that performance will continue to deteriorate as the amount of data increases.

(the purpose)
The object of the present invention is to increase the number of priority routes and increase the priority level without waiting even if an order for data setting / confirmation from the operator is input during mass data setting from other request sources. An object of the present invention is to provide a data setting system, apparatus and method, and a program thereof having a priority function capable of obtaining equivalent results even when setting in multiple stages.

  The data setting system provided with the priority function of the present invention recognizes the priority and the setting data group in the setting data transmitted from the host system and converts them into priority (Func1), and the lower system received from the host When sending data to a lower system through the route, a function for distributing data received from the upper level, a function (Func2) for distributing data received from the upper level to a preset logical route From the time when the count number reaches the number of data registered in advance, the next data transmission is queued (Func4), and when transmitting to the lower system, the maximum number of simultaneous executions of the lower system, And a function (Func 3) for providing a priority control setting file capable of setting the number of priority routes and the like.

The operator assigned to the host system or operation terminal converts the priority assigned when the data is set in the lower system into a priority order that can be identified in the system, and executes the assignment. By establishing a unique route for each distributed data, it is possible to perform a quick process so that a data flow with a high priority does not interfere with other flows.
In addition, considering the elimination of complicated settings when establishing a priority route, it is possible to easily set priority routes and priorities by managing with a setting file called an SG file, and the reflection time is also set in the process. Since it is a restart, the service stop time can be greatly reduced.
Along with the development with priority control of the present invention, in order to process the data identified in the lower system, by installing a limiter for each route and performing queuing, a countermeasure according to the specifications of the lower system Is possible.

According to the present invention, even if an order for data setting / confirmation from an operator is input during a large amount of data setting from another request source, the upper limit of the limiter for the priority route for the operator is not generated without waiting time. If not exceeded, a response performance of less than 1 second can be obtained. In the future, by increasing the number of priority routes, even if the priority level is set in multiple stages, it is certain that the same result as above will be obtained. In addition, by adding an easy priority setting means using an SG file, it is considered that the system has the potential for various leap forwards.
The data setting system of the present invention is not specialized for a specific environment, but is suitable for all data settings having priority control.

(Example)
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a diagram showing the positioning of the system of the present invention in the entire network.
Server groups constituting an IP network become complicated as services are expanded, while real-time performance for service activation is an indispensable element. Terminals that need to be activated range from terminal devices used by ISP (Internet Service Provider) operators to terminal devices used by end users. Although it is impossible to process all services in real time, it is possible to activate services according to the purpose by realizing priority control based on service contents and data input sources.

In FIG. 1, 10 is a network of a data setting system according to the present invention, 12 is an upper system, 13 and 14 are lower systems, 11 is a data setting based on a data setting request from the upper system 12, This is a data setting system to be transmitted.
20 is a general IP network, 21 and 22 are SIP servers, 23 and 24 are routers, 25 and 26 are VoIP gateways (VoIP GW), 28 and 30 are softphones connected to the VoIP gateways 25 and 26, 27 , 29 are hard phones connected to the VoIP gateways 25, 26.

As described above, the network system to which the present invention is applied includes a plurality of servers 21 and 22 constituting an IP network, a data setting system 10 that manages these, and a host system 12 that executes service activation. The host system 12 executes data setting for the servers 21 and 22 via the data setting system 11.
In an IP network, there are many services realized by cooperation of a plurality of servers. For example, in the VoIP service, data must be set in a SIP server, a call agent, etc., and in the VPN service, data must be set in a PE (provider edge) or the like. In order to realize the activation of complex services with different data setting destinations for each of these services, flow-through is being studied (Takayuki Nakao et al. “Study on application of workflow system to OSS” IEICE Spring National Convention, Mar. 2001 (see Non-Patent Document 1), and Takayuki Nakao et al. “SO Processing Method Flexible to NE Service Functions” IEICE Spring National Convention, Mar. 2002 (see Non-Patent Document 2)) .

FIG. 3 is a schematic diagram of a data setting system having a priority function according to an embodiment of the present invention.
Claims 1, 2, and 3 show the positioning of each claim in FIG. 3, and each has a characteristic configuration.
From the host system 12, a large amount of data groups, operators, and the like perform emergency data setting and confirmation using a GUI (graphical user interface). Compared with a large amount of data setting groups, the operator's emergency data setting and confirmation work has a higher priority and requires real-time processing. However, in the case of a large amount of data group setting, the next month, the next week, etc. Since there is a time delay before actual service-in is performed, it is not necessary to be reflected when data is input.

Data set from the host system 12 is data (including a priority flag) 11D having mixed priorities. Here, data having the priority flag h is high priority, data having the priority flag m is medium priority, and data having the priority flag l is low priority.
When mixed data is input to the present system (data setting system) 11, first, sorting by priority flags is performed (claim 1) (11 </ b> A). That is, as shown in FIG. 3, the system 11 is divided into a route of priority h (left side), a route of priority m (center), and a route of priority l (right side).

Next, limiter setting is performed according to the lower system (claim 2) (11B). In other words, a limiter for limiting the number of commands input to the lower system (server) is provided, and the number of commands input is managed so as not to exceed a preset number of commands.
Further, a priority control setting file (SG file) 12 used for the priority route level is provided (claim 3) (12A). The SG file 12 can set the priority control for three items: a) the maximum number of simultaneous executions of one subordinate system, b) the number of priority routes, c) the priority level, and the maximum number of simultaneous executions.

FIG. 4 is a diagram of a priority control flow in the present invention.
This is the first feature (corresponding to claim 1) of the present invention. As shown in FIG. 4, the emergency data is set by the operator while the large volume data 41 is set. When 42 is performed, the information is input from the host system 12 to the system 11. In this system 11, it is sent to the lower system 13 through the processing steps of Func 1, Func 2, Func 4, and Func 3. Hereinafter, each processing stage will be described.
(Func1): The priority flag assigned in the host system 12 is converted into a form that can be identified in the system 11 (step 51).
(Func 2): The route through which the operator's emergency data setting / confirmation is distributed is set as the priority route, and the route from the other request source is set as the normal route (step 52).
(Func4): Control by a limiter is performed (step 53).
(Func3): The data passing through each route is distributed to the lower system 13 after being controlled by the limiter. For data with low priority, data on a route with high priority is confirmed, and data is transmitted to the lower system 13 only when there is no data, so that data with higher priority is always given priority to the lower system 13. Sent.

In FIG. 4, the function (control function by the limiter) which is the second feature (corresponding to claim 2) of the present invention will be described.
Control by the limiter includes the following items.
(1) The operator's setting / confirmation process is performed by passing a priority route, and using a session of the lower system 13 that is secured regardless of the waiting state of the normal route, Achieve unaffected processing time.
(2) When data is input to each route in the state where both the normal route and the priority route are queued, make sure that there is no data in the priority route when the data of the normal route is transmitted. Therefore, the priority route data is preferentially transmitted to the lower system 13 regardless of the arrival order.
(3) The number of parallel executions considering the lower system 13 is assigned to each of the priority route and the normal route independently, and the priority route can secure the number of parallel executions that can be used independently of the number of simultaneous executions of the normal route. Limiters can be set.

FIG. 5 is an explanatory diagram of overtaking control by priority control according to the present invention.
FIG. 5 shows the overtaking control of the system that performs the priority control by identifying the priority flag among the same operations as in FIG.
When the emergency data setting 42 is performed while the mass data 41 is set in the host system 12, this is given the priority flag h in the host system 12.
When each data to which the priority flags h, m, and l are input is input to the system 11, (Func 1) 51 </ b> A is configured so that the priority identifier of the data provided by the higher system 12 can be recognized by the system 11. (Priority (high) h → 1, priority (medium) m → 2, priority (low) l → 3,... (Assignment of identifier for this system)). Also, with this flag, the route according to each priority (1, 2, 3) is distributed, and after passing through each route, the order handled as data is disassembled for each function and is sent to the command. It is handled in a format and transmitted to the lower system 13.

  In (Func2) 51B, distribution to each route corresponding to the assigned priority identifier is performed. That is, the route is assigned to each route for priority 1, priority 2, and priority 3, and is queued. In (Func4), control by a limiter is performed, and the limiter number of the limiter of priority 1 is defined as C, the limiter number of the limiter of priority 2 is defined as B, and the limiter number of the limiter of priority 3 is defined as A. In (Func 3) 54, distribution to the lower system 13 is performed, and the data of the route of the first priority 1 is overtaken and sent to the lower system 13. Next, the data of the route with the priority 2 is sent to the lower system 13, and finally, the data of the route with the priority 3 is sent to the lower system 13.

In fact, most of the data that arrives at the limiter is written on the command base (basically a DB (database) of the lower-level system 13 so as to perform write processing. For example, update ~, create ~, etc.) , Etc.) and written in the DB of the lower system 13. In this embodiment, writing to the DB is taken as an example, and conversion to the command base is performed. However, the processing method is not limited to this.
In addition, as shown in FIG. 5, when data is input to each route of the system 11 in the order indicated by numbers 1 to 7, overtaking processing occurs for high priority data, and the arrival order No. 6 and No. 7 (highest priority) are given the highest priority, and the command is executed to the lower system 13. Within each route, sequential processing is performed.
In this embodiment, the number of priority routes is three types of 1 to 3, but may be two types of priority and normal. Of course, there may be four or more types.

FIG. 6 is a priority control sequence chart in the present invention.
So far, the basic flow form has been described, but in FIG. 6, a priority control sequence expressing the contents having the above items in an internal process will be described. Here, a right-pointing arrow is a setting request, and a left-pointing arrow is a completion notification.
A large amount of data setting groups and data setting orders from the operator are input to the system 11 via the host system 12. The data group input to the system 11 is converted from a priority flag set in advance in (Func 1) 51 into a format that can be processed inside the system. Here, a normal identifier is assigned to the general user data setting, and a priority identifier is assigned to the operator setting data. Next, data is transferred to the function unit (Func 2) 52 that performs distribution, and the priority data and the normal data pass through the priority route and the normal route, respectively. At that time, in consideration of cooperation with the lower system 13, queuing is performed for an order that is controlled by a predetermined limiter number and exceeds the upper limit value of the limiter.

That is, although the limiter number = C is set for the priority route in the figure, it is queued when the order from the operator exceeds C. For the normal route, the number of limiters is set to A and B, and when a large amount of data group exceeds the total number of limiters (A + B), it is queued and waits (see “Note” in FIG. 6). '). That is, the white box portion is waiting time. The order in the waiting state is executed when the system 11 receives a data setting completion notification from the lower system 13.
The data to which the priority is given is distributed to the lower system 13 as it is, and the data setting is completed when the completion notification is received from the lower system 13.

FIG. 7 is an explanatory diagram of simple setting by the priority control setting file (SG file) in the present invention.
Regarding the priority control setting file (SG file) 12 necessary for realizing the priority control of the data setting for the lower system 13 described so far, particularly the setting data in the system 11 and the setting method thereof will be described. Corresponds to item 3).
By having the SG file 12 as shown in FIG. 7 in the system 11, it is possible to easily set the priority route and the priority level.

In the SG file 12, the following three items can be set for the priority control.
(1) Maximum number of simultaneous executions of one lower system (2) Number of priority routes (3) Priority level, maximum number of simultaneous executions Among the above items, the maximum number of simultaneous executions of one lower system is the entire lower system 13 This is the maximum number of commands that can be executed at the same time. By changing this value, it is possible to design a system that takes into account the specifications of the lower system 13.
The number of priority routes, which has been described so far, is the number of routes through which data with a priority flag can pass according to the priority. In this system, since the number of routes is two, “priority” and “normal”, it is “2” in FIG.

It is possible to control the number of priority routes by changing the “number” that is the number of priority routes.
In addition, the priority level is the maximum number of concurrent executions. The priority level literally sets the priority level in order for the data. In this system, there are two levels: 'priority' and 'normal'. Are mapped to “1” and “2”, respectively, and the priority becomes higher in ascending order of numerical values. The maximum number of concurrent executions is a limiter value corresponding to each route. When data is set in the lower system 13, the number of command executions for each route is determined also in the lower system 13, and can be changed according to the performance and specifications of the lower system 13.

Since the maximum number of concurrent executions of one subordinate system is the sum of the maximum number of concurrent executions (limiter value) for each priority level, the following relational expression is established as described above the file in FIG.
(Maximum number of concurrent executions of one lower system) = Maximum number of concurrent executions per Σ priority level (number of limiters) (Equation 1)
Therefore, taking (*) in the figure as an example, if the maximum number of concurrent executions of the lower system is 310, back calculation is performed (maximum number of concurrent executions of one lower system = 310) = 10 (priority) +300 ( Normal)
... (Formula 2)
It is possible to easily set in the form of.

The number of priority routes also depends on the system performance, but can be changed from 1 to n by simply changing the numerical value.
Although the SG file has been described so far, any one of the maximum number of simultaneous executions, the number of priority routes, the priority level, and the maximum number of simultaneous executions of one lower system can be easily set by simply changing only the numerical values. In addition, when the SG file is changed, the machine itself does not need to be restarted when it is reflected in this system, and the service can be performed only by restarting the process. Stops can be minimized.

  7 is described in the upper part of the SG file, for example, in the example of (*), the lower system ID (100000111), the maximum number of simultaneous executions of the lower system (3), the number of priority routes (2), priority level, maximum number of simultaneous executions (1, 10 | 2, 300), node type, node ID (123456, 100000999). The other columns are set in the same way.

(Application examples)
Hereinafter, as an application example of the present invention, first, a priority control function will be considered.
When implementing the present invention, immediacy is not required for all services. For example, a user who is newly registered may be accompanied by hardware work such as installation of terminal equipment. If the setting is completed, the user's service provision is satisfied.
In contrast to this, when activation of a service directly operated by the user occurs, it is necessary to guarantee a response equivalent to a normal Web operation.

Next, consider the priority level.
(Service activation by operator)
There are three types of service activation by the operator.
(1) Prior construction: Newly registered users are the main targets. Since it involves the construction of hardware such as terminal devices and lines, real-time processing is not required because it only needs to be completed by a predetermined date.
(2) Additional service setting: When setting an additional service requested by an existing user, early implementation is desirable, but adjustment with the user is possible.
(3) Emergency operation: Activation for restoring erroneous data setting due to an operation error or the like, and the real-time property is required for the operator operation.

(Service acceleration by end users)
Application for additional services, ON / OFF of service settings, etc. can be considered. When the end user directly activates the service, it is necessary to guarantee the real-time property in all cases.

The priority level for each operation described in the previous section is in the following order.
Priority level 1: User operation Priority level 2: Emergency operation Priority level 3: Additional service setting Priority level 4: Prior construction However, service activation with a low priority level is performed when there is a large amount of activation with a high priority level. Since there is a concern about extremely slow command processing, it is necessary to count up the waiting time and raise the priority level according to the elapsed time.

Next, consider command priority level transitions.
When a large amount of service activation with a high priority level is input, it is assumed that the processing time for service activation with a low priority level is extremely delayed. If it has elapsed, processing for shifting to a higher priority queue is also required. That is, as the predetermined time elapses, the level is increased from priority route 4 to priority route 3, priority route 3 to priority route 2, and priority route 2 to priority route 1.

Next, a processing model in priority control will be described as an application example of the present invention.
Here, for example, the following processing model is considered.
(1) Data analysis function part (extracts data items necessary for service activation)
(2) Data setting function section (converts data items into a setting command format for each server and sends it to the server)
(3) Service opening test function section (executes tests based on test scenarios)
When multi-vendor servers with different function deployments are applied depending on the scale of system installation, the above (2) data setting function unit is aware of which server the service function is deployed in command editing or input processing. It consists of processing that depends on the service and processing that depends on the physical configuration of the server. By separating these (1) to (3), the data distribution process can be made independent of the server or network configuration, and the influence is minimized even when the number of servers is increased or decreased due to the implementation (degeneration or distribution) of functions. The

Next, a method for extracting a target server will be considered.
In the data distribution processing for the above (2) data setting, it is necessary to extract a server that is a data setting target. As a method of extracting a server, there is a method of converting a server from a logical server separated for each function into a physical server actually deployed.
(Conversion method from logical server to physical server)
The adapter manages the correspondence table between logical servers and physical servers. When inputting a command to the server, the server to which the command is actually transmitted is extracted by referring to the correspondence table between the logical server and the physical server.
(Data distribution processing)
Servers that distribute data between adapters (between lower systems) and processing flows can be logical servers only, and data distribution enables command input processing by considering only logical servers.

(Priority control program and recording medium)
If each operation step of the priority control flow of FIG. 4 or the priority control sequence of FIG. 6 is coded, converted into a program, and the completed program is stored in a recording medium such as a CD-ROM, the priority control according to the present invention is performed. This is convenient when buying and selling or lending a program, and the present invention can be easily realized by mounting the recording medium on a computer that is the system, installing the program, and causing the computer to execute the program.
