Description

  The present invention relates to a service management system that performs resource reduction of another service in order to increase the resource of a certain service in an environment where a plurality of services are executed across a plurality of bases.

  When a large-scale disaster occurs, calls such as safety confirmation are concentrated in the affected area, and the processing capacity is insufficient. The facility for handling calls is prepared about twice as much as normal traffic, but in the event of a large-scale disaster, traffic of several tens of times may be concentrated. However, since the processing capacity is insufficient, it is necessary to borrow resources from nearby bases and increase the capacity.

  In the cloud environment, the physical machine that performs the actual processing and the logical virtual machine that runs on it are separated, and the number of virtual machines can be increased by increasing the number of physical machines used according to the service load. By doing so, the processing capability can be increased.

  As described above, a technique for increasing / decreasing virtual machines in accordance with increase / decrease in service load is known. For example, Patent Document 1 discloses a technique for monitoring the load of a paid-out virtual machine with a timer and executing virtual machine increase / decrease according to the load increase / decrease.

JP 2011-175338 A

  However, since the technique disclosed in Patent Document 1 is based on the premise that resources are pooled abundantly, there was no assumption that other services would be reduced in order to add a certain service.

  Actually, a plurality of services have policies for each, and it is necessary to allocate resources with high performance while satisfying them. That is, it is necessary to determine a resource to be released by another service based on a policy for adding a certain service.

  For example, if a certain service X is using resources across bases A and B, and if the service Y to be added requests a resource with a smaller network delay, the service X to be removed is viewed from the service Y. It is necessary to reduce the resources at the base where the network delay becomes smaller. In other words, simply satisfying the load of a certain service does not allow the interchange of resources that satisfy the policies of a plurality of services including other services.

  The present invention has been made in view of the above-described problems, and its purpose is to provide each of an extension target service and a reduction target service in an environment where a plurality of services are executed across a plurality of bases. It is to enable service management that realizes the addition of resources to the service to be added and the reduction of resources of the service to be removed while satisfying the policy.

An instruction to increase / decrease the resources at the bases of a plurality of services that have resources and are executed across the bases, and the service management server receives the instruction to increase / decrease and sets the policy of the service This is a service management system between bases that increases or decreases the resources based on the above.

  The inter-base service management server according to the present invention has a resource at a plurality of bases connected via a communication network, and instructions for increasing / decreasing the resource at the bases of a plurality of services executed across the bases And the inter-base service management server that increases and decreases the resources based on the service policy.

  The inter-base service management method according to the present invention includes an instruction to increase / decrease the resource at a base of a plurality of services that have resources at a plurality of bases connected via a communication network and are executed across the base. And a service management method between bases that receives the instruction to increase / decrease and increases / decreases the resource based on the policy of the service.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the preferred embodiments described below are technically preferable for carrying out the present invention, but the scope of the invention is not limited to the following.
(First embodiment)
FIG. 1 is a block diagram showing a configuration of a service management system according to the first embodiment of this invention. As shown in FIG. 1, the inter-base service management system according to the present embodiment includes information on a plurality of bases 41, bases 4i, bases 4m (i and m are positive numbers), and services operated at the bases 41 to 4m. A service management server 3 to be managed and a service management terminal 2 are provided. The service management server 3 and the bases 41 to 4 m are connected via the communication network 1. In FIG. 1, services that operate at the base 41 are services X1 (411) and Y1 (412), services that operate at the base 4i are services X2 (4i1) and Z1 (4i2), and services that operate at the base 4m are services Y2 ( 4m1) and Z2 (4m2).

  The bases 41 to 4m use, for example, a virtualization technology, and a call service such as a mobile phone or a packet service is constructed by combining virtualized resources. The bases 41 to 4m are realized by a data center that is managed by a telecommunications carrier that provides a plurality of services over a wide area using a plurality of bases, and includes computers and network devices. A user terminal or the like is connected to the bases 41 to 4m via a wireless or wired communication network (not shown in the figure).

  In the bases 41 to 4m, services X, Y, and Z are operating, and each of the bases 41 to 4m is configured by X1 to X2, Y1 to Y2, and Z1 to Z2. For service X, subscript 1 X1 becomes the home base, and X2 that performs processing in cooperation with X1 is called to execute processing. Here, a two-stage service is taken as an example, but a multi-stage service of three or more stages can be handled in the same manner. Here, it is assumed that the subscripts 1, 2,...

  The service management terminal 2 includes an increase / decrease setting request unit 21. The increase / decrease request means 21 recognizes the load imbalance between services, and then gives as input the amount of resources that can be accommodated between the service to be reduced and the service to be added, thereby managing the information. It is sent to the reduction pattern generation means 31 of the server 3.

  The communication between the service management terminal 2 and the service management server 3 may be a local cable connection or via the communication network 1 or other networks, and the implementation method is not limited.

  The service management server 3 includes a reduction pattern generation unit 31, a service information storage unit 32, an extension pattern generation unit 33, and an increase / decrease pattern determination unit 34.

  The reduction pattern generation unit 31 generates a list of releasable resources among resources held by the service to be reduced, ranks them according to the policy, and generates a list of reduction patterns.

  The service information storage unit 32 is a service of all services (here, there are services X, Y, and Z, each of which is configured by X1 to X2, Y1 to Y2, and Z1 to Z2) that operate at the bases 41 to 4m. Stores policy (home base, minimum delay, minimum total bandwidth, availability of coexistence within base, etc.), service status (allocated resource amount, current service allocation, load, etc.), service priority, etc.

  The expansion pattern generation unit 33 generates a list of resources necessary to satisfy the expansion request, performs ranking according to the policy, and generates a list of expansion patterns.

  The increase / decrease pattern determination means 34 acquires the priority of the service to be increased / decreased from the service information storage unit 32, and from the list of the relationship and the increase / decrease pattern, the reduction pattern of the reduction target service and the extension target service Determine the expansion pattern.

According to the inter-base service management system of this embodiment, the load exceeding the processing capacity of the facility is determined in order to determine the resource interchange pattern according to the priority while utilizing the policy of the service to be added and the service to be removed. Even when a problem occurs, resources with better conditions can be allocated to a service with a higher priority.
(Example)
As an example of the first embodiment, an example is shown in which a resource to be released from a reduction target service is determined and an increase / decrease pattern is determined in order to add a resource to the extension target service. First, the premise of the service to be increased / decreased will be described. FIG. 2 shows the deployment status of bases A to D of the service X to be reduced.

  The service X is composed of X1 to X4 and is called in the order of X1, X2, X3, and X4 to perform processing. A total of 30 resources of 20 are assigned to X1, 30 to X2, 20 to X3, and 10 and 20 to X4, respectively. In X4, the resources are divided into two, 10 and 20, and the process is called from the ratio of the allocated resource amount from X3. The bases A to D are separated from each other in a network, and a network delay occurs between the bases. In addition, it is assumed that there is a certain upper limit on the network bandwidth between bases.

  As for the load when the service X is executed, the load generated in each of X1 to X4 is the same value for simplicity. In the example of FIG. 2, since the allocated resource amounts of X1 to X4 are different, when processing the load 20, X1 and X3 are used 100% and X2 and X4 are used 67%. become. Furthermore, since X4 is deployed in two locations, X4 at location A is processing 1/3 of the load 20, and X4 at location B is processing the remaining 2/3. It will be.

  Similarly, FIG. 3 shows the deployment status at the bases A to D of the service Y to be added. The service Y represents a situation in which only Y1 has been deployed at the base A and Y2 is to be added. The amount of resources allocated to Y2 to be added is 10 which is the same as Y1.

  FIG. 4 is a flowchart showing a processing procedure in the embodiment of the service management server of the inter-base service management system shown in FIG.

  First, the maintenance person designates three parameters, that is, the amount of resources to be added, the service to be added, and the service to be removed, calls up the increase / decrease request means 21 of the service management terminal 2, and increases / decreases to the service management server 3. (Step A1).

  The reduction pattern generation means 31 of the service management server 3 receives the instruction to execute the increase / decrease setting and generates a reduction pattern candidate (step A2). Reduction pattern candidates are determined by calculating the amount of released resources, average delay, total bandwidth, and local bandwidth for each of the services X1 to X4 of the reduction target.

  The reduction pattern generation means 31 reads the policy of the service to be deleted stored in the service information storage unit 32, and ranks the candidates according to the policy of the service to be deleted (Step A3).

  FIG. 5 shows examples of reduction pattern candidates. Here, five reduction pattern candidates are shown, and the policy of service X is that the average delay is small, the total bandwidth is small, the local band (refers to the band between the bases, for example, the base A In the case of the location between the location B and the location B, priority is given to those having a smaller value of AB. According to this policy, the candidate for the reduction pattern of the base B is # 1.

  In addition, as a policy of the service X, the service X is consolidated as close to the home base as possible. According to this policy, candidates for the reduction patterns of bases D and A are # 2 and # 3 in the order of the bases far from the home base C where X1 exists.

  Further, although the quality of the service is deteriorated, the candidate for the reduction pattern of X4 of the base A is # 4 due to the policy of collecting things far from the home base C. Finally, according to the policy of consolidating to the home base as much as possible, the candidate for the reduction pattern of the base C is # 5 having the lowest ranking.

  As described above, the reduction pattern generation unit 31 generates reduction pattern candidates as shown in FIG.

  Subsequently, the additional pattern generation unit 33 generates additional pattern candidates (step A4). Candidate expansion patterns are calculated by calculating the amount of consumed resources, average delay, total bandwidth, and local bandwidth for Y2 to be expanded.

  The extension pattern generation unit 33 reads the policy of the service to be added stored in the service information storage unit 32, and ranks the candidates based on the policy of the service to be added (step A5).

  FIG. 6 shows examples of expansion pattern candidates. Here, four additional pattern candidates are shown, and as a policy for service Y, priority is given to a policy in which the average delay is as small as possible, a total bandwidth is small, and a local bandwidth is small. In addition, the average delay within the same base is assumed to be negligible. Based on these policies, the candidates for the additional patterns of bases A, C, D, and B are # 1, # 2, # 3, and # 4 in ascending order of average delay.

  In this way, the additional pattern generation unit 33 generates additional pattern candidates.

  Thereafter, the increase / decrease pattern determination means 34 selects one of the three accommodation policies, ie, expansion priority, reduction priority, and the like, according to the priority of the service (step A6). The service priority is stored in the service information storage unit 32. In the accommodation policy, when the priority of the service to be added is higher than that of the service to be removed, the extension priority is given. Further, when the priority of the service to be reduced is higher than that of the extension service, reduction priority is given. If two services have the same priority, they are equal.

  Here, the accommodation policy is automatically selected based on the priority of the service, but the maintenance person may give the accommodation policy as a parameter to the increase / decrease setting request means 21. In this case, the increase / decrease pattern is determined by the accommodation policy designated by the maintenance person regardless of the priority of the service.

  Finally, the increase / decrease pattern determining means 34 determines an accommodation pattern that satisfies the selected accommodation policy (step A7).

  When the accommodation policy is priority for expansion, first, a candidate for a reduction pattern that can satisfy the expansion pattern candidate # 1 in FIG. Here, looking at the candidate for the reduction pattern in FIG. 5, if # 3 which is the candidate for the released resource amount 10 is selected at the site A, the requirement of # 1 for the additional pattern candidate can be satisfied. The pattern determining means 34 determines the reduction pattern # 3 and the extension pattern # 1 as final accommodation patterns.

  When the accommodation policy is priority to reduction, first, a candidate for an extension pattern that can satisfy the reduction pattern candidate # 1 in FIG. Here, looking at the extension pattern candidates in FIG. 6, if # 4 which is a candidate for the consumption resource amount 10 is selected at the base B, the requirement of the reduction pattern candidate # 1 can be satisfied. The pattern determining unit 34 determines the reduction pattern # 1 and the extension pattern # 4 as final accommodation patterns.

  When the accommodation policies are equal, candidates are extracted from the top of the list of expansion pattern candidates and the list of reduction pattern candidates, and the increase / decrease pattern that matches in the closest order is selected.

  First, with reference to extension pattern candidate # 1 in FIG. 6, a search is made for a candidate for a reduction pattern that can satisfy it. Here, looking at the candidate for the reduction pattern in FIG. 5, if # 3 which is the candidate for the released resource amount 10 is selected at the site A, the requirement of the candidate for the additional pattern # 1 can be satisfied. Therefore, the increase / decrease pattern determination means 34 sets the decrease pattern # 3 and the extension pattern # 1 as the first candidates for the accommodation pattern. The order difference between the reduction pattern # 3 and the extension pattern # 1 is 2.

  Next, on the basis of the reduction pattern candidate # 1 in FIG. 5, a search is made for an extension pattern candidate that can satisfy it. Here, looking at the candidate for the expansion pattern in FIG. 6, if # 4 which is the candidate for the consumed resource amount 10 is selected at the base B, the requirement of the candidate for reduction pattern # 1 can be satisfied. Therefore, the increase / decrease pattern determination means 34 sets the decrease pattern # 1 and the extension pattern # 4 as the second candidate for the accommodation pattern. The order difference between the reduction pattern # 1 and the extension pattern # 4 is 3.

  Here, when the rank difference of the first candidate is compared with the rank difference of the second candidate, the rank difference of the first candidate is smaller. Are selected as candidates for the currently available accommodation pattern.

  Similarly, with reference to extension pattern candidate # 2 in FIG. 6, a search is made for a reduction pattern candidate capable of satisfying it. Here, looking at the candidate for the reduction pattern in FIG. 5, if # 5 which is the candidate for the released resource amount 10 is selected at the base C, the requirement of the candidate for the additional pattern # 2 can be satisfied. Therefore, the increase / decrease pattern determining means 34 sets the decrease pattern # 5 and the extension pattern # 2 as newly generated accommodation pattern candidates. The order difference between the reduction pattern # 5 and the extension pattern # 2 is 3.

  Here, when comparing the rank difference between the currently effective accommodation pattern candidates determined immediately before and the rank difference between the newly generated accommodation pattern candidates, the rank difference between the currently effective accommodation pattern candidates is smaller. The increase / decrease pattern determining means 34 continues to select a currently effective interchange pattern candidate having a rank difference of 2.

  Subsequently, on the basis of # 2 of the candidate for reduction pattern in FIG. 5, a candidate for an extension pattern that can satisfy that is searched. Here, looking at the extension pattern candidates in FIG. 6, if # 3, which is a candidate for the consumption resource amount 10, is selected at the site D, the requirement of the reduction pattern candidate # 2 can be satisfied. Therefore, the increase / decrease pattern determining means 34 sets the decrease pattern # 2 and the extension pattern # 3 as newly generated accommodation pattern candidates. The order difference between the reduction pattern # 2 and the extension pattern # 3 is 1.

  Here, when the rank difference between the currently effective accommodation pattern candidates determined immediately before and the rank difference between the newly generated accommodation pattern candidates are compared, the rank difference between the newly generated accommodation pattern candidates is 1 Since it is small, the increase / decrease pattern determining means 34 selects a newly generated candidate having a rank difference of 1 as a currently effective accommodation pattern candidate.

  The comparison of the above-mentioned interchange patterns is repeated, and finally, the increase / decrease pattern determining means 34 uses the interchange pattern whose rank difference is 1, that is, the decrease pattern # 2 and the extension pattern # 3 as the final interchange pattern. decide.

According to the inter-base service management system of this embodiment, an increase / decrease pattern based on the policy of each service is generated, and an interchange pattern can be determined by matching, so the policies of the service to be added and the service to be reduced can be determined. Utilizing it, it is possible to determine the accommodation pattern according to the priority of the resource.
(Second Embodiment)
Next, a second embodiment of the present invention will be described.

  This embodiment is different from the first embodiment in that an availability restriction is added to the policy of the service to be added stored in the service information storage unit 32 of FIG. This availability constraint is a policy that service operating locations are distributed to different bases, and expansion pattern candidates are different.

  The flowchart of the processing procedure of this embodiment is the same as the flowchart of the first embodiment shown in FIG. A process in which the maintenance person instructs the service management server 3 to execute increase / decrease (Step A1), a process for generating and ranking reduction pattern candidates (Step A2, Step A3), and an additional pattern candidate The process (step A4) is the same as in the first embodiment.

  Next, the extension pattern generation means 33 ranks candidates according to the policy of the service to be added (step A5). The policy of the service to be added is stored in the service information storage unit 32. In the present embodiment, an availability constraint policy is added, and it is assumed that Y1 and Y2 must be placed at different locations.

  FIG. 7 shows examples of expansion pattern candidates to which availability constraints are applied. Here, the base A where Y1 has already been deployed is excluded from the candidates for expansion patterns due to availability constraints, and the candidates for expansion patterns are narrowed down to three. As a policy of service Y, priority is given to a policy in which the average delay is as small as possible, a policy in which the total bandwidth is small, and a policy in which the local bandwidth is small. Based on the policy, the candidates for the additional patterns of bases C, D, and B are # 1, # 2, and # 3 in ascending order of average delay. In this way, the additional pattern generation unit 33 generates additional pattern candidates.

  The next step, that is, the process in which the increase / decrease pattern determining means 34 selects the accommodation policy (step A6) is the same as in the first embodiment. Finally, the increase / decrease pattern determining means 34 determines an accommodation pattern that satisfies the selected accommodation policy (step A7).

  When the accommodation policy is priority for expansion, first, a candidate for a reduction pattern that can satisfy the expansion pattern candidate # 1 in FIG. Here, looking at the candidate for the reduction pattern in FIG. 5, if # 5, which is the candidate for the released resource amount 10, is selected at the site C, the requirement of # 1 for the additional pattern candidate can be satisfied. The pattern determining unit 34 determines the reduction pattern # 5 and the extension pattern # 1 as final accommodation patterns.

  When the accommodation policy is priority to reduction, first, a candidate for an extension pattern that can satisfy the reduction pattern candidate # 1 in FIG. Here, looking at the extension pattern candidates in FIG. 7, if # 3, which is a candidate for the consumption resource amount 10, is selected at the base B, the requirement of the reduction pattern candidate # 1 can be satisfied. The pattern determining unit 34 determines the reduction pattern # 1 and the extension pattern # 3 as final accommodation patterns.

  When the accommodation policies are equal, candidates are extracted from the top of the list of expansion pattern candidates and the list of reduction pattern candidates, and the increase / decrease pattern that matches in the closest order is selected.

  First, on the basis of the extension pattern candidate # 1 in FIG. Here, looking at the candidate for the reduction pattern in FIG. 5, if # 5, which is the candidate for the released resource amount 10, is selected at the site C, the requirement of # 1 for the additional pattern candidate can be satisfied. The pattern determination unit 34 sets the reduction pattern # 5 and the extension pattern # 1 (rank difference 4) as the first candidates for the accommodation pattern.

  Next, on the basis of the reduction pattern candidate # 1 in FIG. 5, a search is made for an extension pattern candidate that can satisfy it. Here, looking at the extension pattern candidates in FIG. 7, if # 3, which is a candidate for the consumption resource amount 10, is selected at the base B, the requirement of the reduction pattern candidate # 1 can be satisfied. The pattern determining unit 34 sets the reduction pattern # 1 and the extension pattern # 3 (rank difference 2) as the second candidate for the accommodation pattern.

  Here, when comparing the rank difference of the first candidate with the rank difference of the second candidate, the rank difference of the second candidate is smaller. The candidate is selected as a candidate for the currently effective accommodation pattern.

  Subsequently, on the basis of # 2 of the extension pattern candidates in FIG. Here, looking at the candidate for the reduction pattern in FIG. 5, if # 2 which is the candidate for the released resource amount 10 is selected at the site D, the requirement for the extension pattern candidate # 2 can be satisfied. The pattern determining unit 34 uses the reduced pattern # 2 and the additional pattern # 2 (rank difference 0) as newly generated accommodation pattern candidates.

  Here, when the rank difference between the currently effective accommodation pattern candidates determined immediately before is compared with the rank difference between the newly created accommodation pattern candidates, the rank difference between the newly created accommodation pattern candidates is smaller. The increase / decrease pattern determining means 34 selects a newly generated candidate with a rank difference of 0 as a candidate of a currently effective accommodation pattern.

  Since this accommodation pattern candidate is minimized when the rank difference is 0, the increase / decrease pattern determination means 34 determines the reduction pattern # 2 and the extension pattern # 2 as final accommodation patterns.

  According to the inter-base service management system of this embodiment, even when availability constraints are added to a policy, an increase / decrease pattern candidate corresponding to the policy can be generated, and an accommodation pattern can be determined by the matching. Utilizing the policies of services and services to be removed, it is possible to determine accommodation patterns according to resource priorities.

  The present invention is not limited to the above-described embodiment, and various modifications are possible within the scope of the invention described in the claims, and it is also included within the scope of the present invention. Not too long.
