  EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated with reference to drawings.

(First embodiment)
FIG. 1 is a block diagram showing a configuration of a management system in the distributed computing environment 1 according to the first embodiment of this invention.

  The management system shown in FIG. 1 includes a management device 10, m network devices 30 (m is an integer of 2 or more), and n computers 50 (n is an integer of 2 or more).

  The management device 10 determines the network device 30 and the computer 50 to be assigned to the application.

  The network device 30 is connected to the management device 10 and the computer 50 and is also connected to other network devices 30.

  Specific examples of networks that connect the management apparatus 10, the network apparatus 30, and the computer 50 include a local area network, a wide area network, and the Internet.

  Then, the network device 30 transfers the data necessary for processing the process, which has been transferred to itself, on the network path connecting the computers 50 to the computer 50 that needs the data.

  Specific examples of the network device 30 include various devices such as a firewall and a load balancer in addition to a router and a switch.

  The computer 50 processes a process constituting an application assigned by the management apparatus 10.

  Further, when the computer 50 processes a process with another computer 50 in parallel, the computer 50 transmits / receives data necessary for the process to / from the other computer 50.

  Specific examples of the computer 50 include general-purpose or specific processing PCs and servers, and virtual machines operating on these.

  FIG. 2 is a block diagram illustrating a configuration of the management apparatus 10.

  The management apparatus 10 illustrated in FIG. 2 includes a policy management block 110, a management interface 120, a global monitor block 130, a resource management block 140, a route calculation block 150, a scheduler block 160, and a setting instruction block 170. Have.

  Note that a block indicates one functional unit realized by at least one of software, a program, and hardware.

  The policy management block 110 holds a policy setting for assigning the network device 30 and the computer 50 to a predetermined application.

  As an example of the policy, for example, when the user is charged when using the distributed computing environment 1, the network device 30 and the computer assigned to the application that the user requests to execute according to the charging status of the user 50 is changed.

  The policy can be set from an external device via the input / output 11.

  The management interface 120 is an interface with the network device 30.

  The management interface 120 receives monitor information transmitted from the network device 30 such as computer monitor information and network device monitor information described later, and transmits various notifications and requests to the network device 30 and the computer 50. To do.

  There are various methods for transmitting the monitor information to the management apparatus 10, such as the management apparatus 10 requesting transmission of the monitor information, or the network apparatus 30 or the computer 50 actively transmitting the monitor information.

  The notification and request transmission to the computer 50 are performed via the network device 30. However, if the management device 10 and the computer 50 are directly connected, they can be transmitted without the network device 30.

  The global monitor block 130 monitors the usage status and load status of the network device 30 and the computer 50 based on the network device monitor information and the computer monitor information received by the management interface 120.

  Then, the global monitor block 130 outputs load information indicating the usage status and load status of the monitored network device 30 and computer 50 to the resource management block 140.

  Here, the load information includes the network device 30 and the computer assigned to the application, such as information on a user who requests execution of the application to which the network device 30 and the computer 50 are assigned, and information on the execution time of the application. Information about 50 is also included.

  The resource management block 140 manages information related to each network device 30 and the computer 50 such as where each network device 30 and the computer 50 exists on the network or the load status of each network device 30 and the computer 50. This information includes information such as which computer 50 is transferring data via which network route.

  The resource management block 140 is a value indicating static information such as the specifications of the network devices 30 and the computers 50 and the load status of the network devices 30 and the computers 50 that need to be changed in allocation to applications. Information indicating a load amount threshold value and weight information for obtaining the load amount of the network device 30 and the computer 50 are held.

  These pieces of information can be set from an external device via the input / output 12.

  Here, as an example of the weight information, there is an example in which a specific parameter among the parameters indicating the load status is set as the load amount.

  In the following description, it is assumed that two parameters, the CPU (Central Processing Unit) of the computer 50 that processes the process and the memory usage rate, are monitored as the load status of the computer 50.

  In this case, for example, when the weight information is a parameter called the CPU usage rate of the computer 50, the CPU usage rate of the computer 50 is set as the load amount of the computer 50.

  Further, as an example of the weight information, there is an example in which a coefficient to be multiplied to each parameter indicating the load status is set.

  In this case, for example, a coefficient to be multiplied by the CPU usage rate and the memory usage rate is set as the weight information. Then, after multiplying the utilization factors of the CPU and the memory by respective set coefficients, the load amount of the computer 50 is obtained by summing them.

  Then, the resource management block 140 determines whether or not the load amount of the network device 30 or the computer 50 exceeds the threshold based on the load information output from the global monitor block 130 and the weight information.

  As described above, when the weight information is set as a coefficient to be applied to each parameter indicating the load status, the resource management block 140 multiplies the set coefficient to obtain the load amount, and then sets the threshold value. It is determined whether or not it exceeds.

  When it is determined that the load amount of the network device 30 or the computer 50 exceeds the threshold value, the resource management block 140 performs a relocation process for changing the network device 30 and the computer 50 assigned to the application.

  Further, the resource management block 140 is re-executed according to a predetermined setting when the load amount of the network device 30 and the computer 50 becomes less than the threshold value due to a decrease in applications executed in the distributed computing environment 1 or the like. Perform placement processing.

  Here, for example, when the setting is made to reduce the power consumption in the computer 50, the resource management block 140 consumes less power when the process is processed by one computer. The rearrangement process is performed so that the process that has been performed is processed by one computer 50.

  Then, the resource management block 140 outputs schedule information indicating the content of the allocation determined by the rearrangement process to the scheduler block 160.

  The route calculation block 150 calculates a network route for connecting a computer 50 to another computer 50 that needs to transfer data when a computer 50 is newly allocated in the rearrangement process.

  Here, the calculation of the network route includes not only the shortest route between the computers 50 but also obtaining a detour route in order to avoid network congestion. Therefore, the route calculation block 150 acquires information necessary for calculating the network route, such as the link cost for connecting to the network and the policy set in the policy management block 110, from the resource management block 140.

  Then, the route calculation block 150 outputs a route calculation result indicating the calculated network route to the resource management block 140.

  The scheduler block 160 performs scheduling of the network device 30 and the computer 50 based on the schedule information output from the resource management block 140, and the network device 30 that needs to change the process setting or communication setting to be processed by the rearrangement process. The computer 50 is instructed to the setting instruction block 170 to request a necessary setting change.

  In addition, the scheduler block 160 instructs the setting instruction block 170 to notify the network device 30 and the computer 50 when the assignment of the network device 30 and the computer 50 to the application becomes invalid.

  The setting instruction block 170 transmits various contents notifications and requests to the network device 30 via the management interface 120 based on instructions from the scheduler block 160.

  Here, the notification transmitted from the setting instruction block 170 includes, for example, a notification that the computer 50 has been newly assigned to a process.

  The request transmitted from the setting instruction block 170 requests, for example, the computer 50 to change the setting of a process to be processed, or requests the network device 30 and the computer 50 to change the setting of the data transfer destination. There is a setting change request to be made.

  Next, the configuration of the network device 30 will be described.

  FIG. 3 is a block diagram illustrating a configuration of the network device 30.

  The network device 30 illustrated in FIG. 3 includes a network interface 310, a management interface 320, a communication setting management block 330, a communication processing block 340, and a local monitor block 350.

  The network interface 310 is an interface with the computer 50 and other network devices 30 and includes one or more network ports.

  The network interface 310 receives the computer monitor information transmitted from the computer 50 and transmits to the computer 50 notifications and requests to the computer 50 transmitted from the management apparatus 10.

  The management interface 320 is an interface with the management apparatus 10.

  The management interface 320 may be an interface physically different from the network interface 310 or may be a part of a network port included in the network interface 310.

  The management interface 320 notifies the computer 50 sent from the management device 10 that the process 50 has been newly assigned to the process, and changes the setting for requesting the network device 30 and the computer 50 to change the data transfer destination setting. In addition to receiving a request and the like, the network device monitor information and the computer monitor information received by the network interface 310 are transmitted to the management device 10.

  The communication setting management block 330 holds a communication setting indicating a transfer destination of data from the own apparatus. Specifically, the setting of the network port of the transfer destination of the data transferred to the own device is held.

  Then, when the setting change request for requesting the change of the communication setting is transmitted from the management apparatus 10, the communication setting management block 330 changes the communication setting according to the setting change request.

  The communication processing block 340 processes the data transferred to its own device in accordance with the communication settings set in the communication setting management block 330.

  Further, the communication processing block 340 transmits the network device monitor information output from the local monitor block 350 described later and the computer monitor information received by the network interface 310 to the management device 10 via the management interface 320.

  The local monitor block 350 monitors the usage status and load status of its own device.

  Specifically, what is monitored as the usage status of the own device is whether or not data is being transferred in the own device.

  The load status of the own device is monitored by the amount of data per unit time transferred at each network port included in the network interface 310, the state of the communication buffer storing the data to be transferred, and the communication processing block Parameters such as a load of 340, the temperature of the own device, and power consumption.

  Then, the local monitor block 350 outputs network device monitor information indicating the usage status and load status of the own device to the communication processing block 340.

  Next, the configuration of the computer 50 will be described.

  FIG. 4 is a block diagram showing the configuration of the computer 50.

  The computer 50 illustrated in FIG. 4 includes a network interface 510, a communication setting management block 520, a process management block 530, an arithmetic processing block 540, and a local monitor block 550.

  The network interface 510 is an interface with the network device 30 and includes one or more network ports for performing communication.

  The network interface 510 receives notifications and requests to the computer 50 transmitted from the management device 10 via the network device 30 and transmits computer monitor information to the management device 10.

  Note that these transmission / reception can be performed without the network device 30 if the computer 50 and the management device 10 are directly connected.

  Further, the network interface 510 transmits / receives data to / from another computer 50 that performs process processing concurrently via the network device 30.

  The communication setting management block 520 holds a communication setting indicating a transfer destination of data from the own device, and when a setting change request for requesting a change of the communication setting is transmitted from the management apparatus 10, the communication setting is set according to the setting change request. To change.

  The process management block 530 holds settings for processes to be processed by the own device.

  Then, when the setting change request for changing the setting of the process to be processed by the own device is transmitted from the management apparatus 10, the process management block 530 changes the setting according to the setting change request.

  The arithmetic processing block 540 processes the process assigned to the own device according to the setting of the process to be processed set in the process management block 530.

  The arithmetic processing block 540 transfers data to the network device 30 and transmits computer monitor information via the network interface 510 according to the communication settings set in the communication setting management block 520.

  The arithmetic processing block 540 is realized by a general-purpose memory or CPU, an application specific integrated circuit (ASIC) specialized for specific processing, a circuit mounted on an FPGA, or a combination thereof.

  The local monitor block 550 monitors the usage status and load status of the own device.

  Specifically, what is monitored as the usage status of the own device is whether or not a process is being processed in the own device.

  The load status of the own device is monitored by processing the amount of data per unit time transferred at each network port included in the network interface 510, the state of the communication buffer storing the data to be transferred, and the process. These are parameters such as the utilization rate of the CPU and memory, the temperature of the device itself, and power consumption.

  Then, the local monitor block 550 outputs computer monitor information indicating the usage status and load status of the own device to the arithmetic processing block 540.

  Next, the operation | movement of the rearrangement process by the management apparatus 10 is demonstrated.

  First, the resource management block 140 obtains the load amount of each network device 30 and the computer 50 based on the load information and the weight information. Then, the resource management block 140 determines whether or not the relocation processing is necessary based on whether the load amount of the network device 30 or the computer 50 exceeds the threshold value.

  If it is determined that relocation processing is necessary, the resource management block 140 is assigned with the network device 30 or the computer 50 whose load amount exceeds the threshold according to the policy set in the policy management block 110. A candidate for the computer 50 to be newly assigned to the application is selected.

  When selecting a candidate, the resource management block 140 can exclude the computer 50 when it is not appropriate to newly assign an application due to the load status of the computer 50.

  Then, when a new application is assigned to each selected computer 50, the resource management block 140 calculates a network route that connects the computer 50 to another computer 50 that transfers data. To instruct.

  Then, the resource management block 140 determines which period of time the network apparatus 30 and the computer 50 are allocated based on the load status of the computer 50 and the network apparatus 30 selected as candidates.

  It should be noted that various periods can be assigned such as specifying a time such as 10 minutes or 1 hour, or until another process is assigned to the computer 50.

  Next, the operation | movement of the rearrangement process by the management apparatus 10 is demonstrated with reference to FIG. 5 and FIG.

  FIG. 5 is a diagram for explaining an example of the operation of the rearrangement process performed by the management apparatus 10.

  Specifically, it is a diagram for explaining the operation of the management apparatus 10 that performs the rearrangement process when the load amount of the computer 50 that processes the process exceeds a threshold value.

  In the following description, it is assumed that an application is executed according to a predetermined assignment of the computer 50 and the network device 30.

  The management system illustrated in FIG. 5 includes, for example, four network devices 30 (30W, 30X, 30Y, and 30Z) and four computers 50 (50A, 50B, 50C, and 50D).

  Further, it is assumed that the CPU utilization rate of the computer 50 is the load amount of the computer 50 as the weight information. In this case, the management apparatus 10 sets the usage rate of the CPU included in the computer monitor information transmitted from each computer 50 as the load amount of each computer. Hereinafter, the CPU usage rate of the computer 50 is referred to as a computer usage rate.

  In the example of FIG. 5, the utilization rates of the computers 50B, 50C, and 50D are 80%, 50%, and 10%, respectively.

  The numerical value given between each network device 30 indicates the utilization rate of the network path between the network devices 30. Accordingly, the network path utilization rates between the network devices 30W and 30X, between the network devices 30X and 30Y, between the network devices 30Y and 30Z, and between the network devices 30Z and 30X are 10%, 10%, 10%, and 80%, respectively. is there.

  Here, the utilization rate of the network path is, for example, the maximum amount of data transferred per unit time that can be transferred between the network devices 30 with respect to the data transferred per unit time. This is a value indicating the ratio of the data amount.

  The management apparatus 10 can obtain the maximum data transfer amount between the network apparatuses 30 from the specifications of the network port included in the network interface 310, for example. This is because the transfer rate indicating the maximum data transfer amount of the network port can be obtained from the specifications of the network port.

  Then, the management device 10 determines the maximum data transfer amount between the network devices 30 and the data amount per unit time transferred at each network port included in the network device monitor information transmitted from each network device 30. The network utilization rate between the network devices 30 can be obtained.

  Note that the maximum data transfer amount may differ depending on the specifications of the network port between the network devices 30 that perform data transfer. In this case, the maximum data transfer amount of the network port with a small maximum data transfer amount is the maximum data transfer amount between the network devices 30.

  First, when the load amount of the computer 50A that is processing the process exceeds the threshold value, the management apparatus 10 newly adds an application including the process being processed by the computer 50A based on the policy in order to perform the rearrangement process. Computers 50B, 50C, and 50D are listed as candidates for the computer 50 to be assigned.

  Next, the management apparatus 10 calculates one or a plurality of network paths respectively connecting the computer 50A and the computers 50B, 50C, and 50D via the network device 30 that can be allocated based on the policy.

  In the example of FIG. 5, for example, between the computer 50A and the computer 50D, a network path (root (1)) via the network device 30W and the network device 30Z, the network device 30W, the network device 30X, and the network device 30Y A network path (root (2)) via the network device 30Z is obtained.

  Next, the resource management block 140 determines the network device 30 and the computer 50 that are newly allocated to the application including the process being processed by the computer 50A.

  Since data transfer is performed by the network device 30 on the network path, the network device 30 to be assigned to the application can be determined by determining the network path.

  Here, the management apparatus described in Patent Document 1 only determines the allocation of the computers 50 that process the processes. Thus, for example, it is assumed that the management device described in Patent Document 1 determines that the computer 50D having the lowest computer usage rate is allocated.

  In Patent Document 1, the network path is determined by the network device 30. As a result, it is assumed that root (1) which is the shortest path connecting the computer 50A and the computer 50D is determined as the network route.

  Here, the utilization rate of the network path between the network devices 30W and 30Z on the root (1) is as high as 80%. In this case, if the amount of data transferred between the computer 50A and the computer 50D increases, the data transfer between the computer 50A and the computer 50D does not proceed, so that even if the computer 50D is newly assigned to the application. The processing performance commensurate with the computer 50D may not be obtained.

  On the other hand, the management device 10 according to the present embodiment determines the computer 50 and the network device 30 to be newly allocated to the application based on the load status of each network device 30 and each computer 50.

  Here, for example, if the condition that the computer 50 and the network device 30 having a computer usage rate of less than 50% and a network usage rate of less than 50% are allocated in advance is set in the policy management block 110, the management is performed. The device 10 determines a computer 50 to be newly assigned and a network route according to the conditions.

  Since only the computer 50D has a utilization rate of less than 50%, the management apparatus 10 determines the computer 50D as a newly assigned computer 50.

  Further, root (1) and root (2) are obtained as network paths for connecting the computer 50A and the computer 50D, but the management device 10 is a network between the network devices 30W and 30Z on the root (1). Is 80%, while the network utilization rates between the network devices 30W and 30X, the network devices 30X and 30Y, and the network devices 30Y and 30Z on the root (2) are all 10%. In accordance with the set conditions, root (2) is determined as a network route, and each network device 30 on root (2) is determined as a network device 30 that is newly assigned to an application.

  The root (2) becomes a detour route via more network devices 30 than the root (1). However, since the utilization rate of the network between the network devices 30 on the root (2) is low, it is possible to cope with an increase in the amount of data transferred between the computer 50A and the computer 50D. A processing capacity suitable for the computer 50D can be obtained.

  For example, if the condition that the network device 30 and the computer 50 having a computer usage rate of less than 60% and a network usage rate of less than 50% are assigned in advance, the computer 50C and the computer 50D are connected to the computer. Satisfies the setting of less than 60% utilization.

  Then, between the computer 50A and the computer 50C, the route through the network device 30W, the network device 30X, and the network device 30Y, and between the computer 50A and the computer 50D, the route of the above-described root (2) is provided. The network utilization rate satisfies the setting of less than 50%.

  As described above, when the plurality of computers 50 and the network path satisfy the condition, for example, the network 50 which is arbitrarily selected from the plurality of computers 50 and the network path and which has a low computer utilization rate is given priority. By setting in advance a condition such that the number of network devices 30 on the route is three or less, the management device 10 can determine the network device 30 and the computer 50 to be newly allocated to the application. .

  FIG. 6 is a diagram for explaining another example of the operation of the rearrangement process performed by the management apparatus 10.

  Specifically, it is a diagram for explaining the operation of the management apparatus 10 that performs the rearrangement process when the value indicating the load status of the network apparatus 30 exceeds a threshold value.

  In FIG. 6, as in FIG. 5, the numbers given to the computers 50 </ b> B, 50 </ b> C, 50 </ b> D indicate the utilization rate of each computer, and the numbers given between the network devices 30 are between the network devices 30. Shows the network path utilization rate.

  In FIG. 6, data is transferred between the computer 50A and the computer 50D through a network path (root (3)) via the network device 30W and the network device 30Z, and between the computers 50B and 50D. Thus, it is assumed that data is transferred through the network path (root (4)) via the network device 30X, the network device 30W, and the network device 30Z.

  As described above, the management device 50 monitors the data transfer amount per unit time of the network port of each network device 30 when determining the utilization rate of the network path. Therefore, assuming that the data transfer amount per unit time of the network port is the load amount of the network device 30 as the weight information, the rearrangement process is performed when the load amount exceeds the threshold value.

  Here, if the utilization rate of the network between the network devices 30W and 30Z becomes as high as 80%, and the load amount of the network device 30W or the network device 30Z exceeds the threshold value, the management device 10 has the computers 50A and 50B Thus, selection of a candidate for the computer 50 to be newly allocated to an application including a process being processed by the computer 50D and calculation of a network route are performed.

  Specifically, the management apparatus 10 first selects the computers 50B, 50C, and 50D as candidates for allocating processes that the computer 50D is concurrently processing with the computer 50A. In the example of FIG. 6, since the load amount of the computer 50D does not exceed the threshold value, the management apparatus 10 also selects the computer 50D as a candidate.

  In addition, the management apparatus 10 selects the computers 50A, 50C, and 50D as candidates for assigning processes that the computer 50D is processing in parallel with the computer 50B. Also in this case, since the load amount of the computer 50D does not exceed the threshold value, the management apparatus 10 also selects the computer 50D as a candidate.

  The management apparatus 10 calculates a network path that connects the computer 50A and the computers 50B, 50C, and 50D, and a network path that connects the computer 50B and the computers 50A, 50C, and 50D, respectively.

  And the management apparatus 10 determines the computer 50 and network path | route to allocate according to the preset conditions.

  In the example of FIG. 6, the management apparatus 10 determines the computer 50C as the computer 50 to be assigned to the process that the computer 50D has processed in parallel with the computer 50A. Further, the management apparatus 10 determines root (5) as a network path connecting the computer 50A and the computer 50C, and allocates the network device 30W, the network device 30X, and the network device 30Y on the root (5) to the application. The network device 30 is determined.

  In addition, the management apparatus 10 does not change the allocation of the computer 50D to the processes that have been processed in parallel with the computer 50B, and does not change the network path for connecting the root (6) between the computer 50B and the computer 50D. And the network device 30X, the network device 30Y, and the network device 30Z on the root (6) are determined as the network devices 30 to be assigned to the application.

  As described above, the management apparatus 10 determines the network apparatus 30 and the computer 50 that are newly allocated to the application based on the load status of each computer 50 and the network apparatus 30.

  Next, the operation of the management system of this embodiment will be described.

(1) Operation when Newly Assigning Computer 50 to Application FIG. 7 is a sequence diagram showing an operation when a new computer 50 is assigned to an application by the management system of this embodiment.

  First, a computer 50 (hereinafter referred to as a local computer 51) that is processing a certain process monitors the usage status and load status of its own device, and transmits computer monitor information to the management apparatus 10 (step S10).

  The local computer 51 can transmit the computer monitor information at various timings periodically or when the load amount of the own computer exceeds a predetermined threshold.

  The management apparatus 10 determines whether or not the rearrangement process is necessary based on whether the load amount of the local computer 51 exceeds the threshold value.

  If it is determined that the rearrangement process is necessary, the management apparatus 10 assigns a part of the process being processed by the local computer 51 (hereinafter, referred to as a remote computer 52), the local computer 51, A network path for connecting to the remote computer 52 is determined (step S20).

  Then, the management apparatus 10 transmits a setting change request for requesting a change in communication settings to the network apparatus 30 on the determined network path (step S30).

  The network device 30 that has received the setting change request changes the communication setting of its own device in accordance with the setting change request (step S40), and when the setting change is completed, transmits an ACK (Acknowledge) indicating that to the management device 10. (Step S50).

  Upon receiving an ACK from the network device 30, the management device 10 sends a notification to the effect that a new assignment has been made to the remote computer 52 together with a setting change request for requesting a change in the setting of the process to be processed or a change in the communication setting. (Step S60).

  In accordance with the setting change request transmitted from the management apparatus 10, the remote computer 52 performs necessary processing such as changing the setting of the process to be processed, starting the processing of the process, changing the communication setting, etc. (step S70). When completed, an ACK indicating that fact is transmitted to the management apparatus 10 (step S80).

  When receiving the ACK from the remote computer 52, the management apparatus 10 notifies the local computer 51 of a notification indicating that the remote computer 52 is newly assigned to the process processed by the local computer 51 and information related to the remote computer 52. Transmit (step S90).

  When the local computer 51 receives the notification from the management apparatus 10, the local computer 51 notifies the process subject to processing in the remote computer 52 of the content of the notification from the management apparatus 10 (step S95).

  Note that the management apparatus 10 can also perform the processing from step S60 to step S80 first before performing the processing from step S30 to step S50. For example, when a process already started by the local computer 51 is processed by the remote computer 52, it is desirable to set the remote computer 52 first.

  The management apparatus 10 can also overlap the processing from step S30 to step S50 and the processing from step S60 to step S80. In this case, the management apparatus 10 performs processing of waiting for reception of ACK from the network apparatus 30 and the remote computer 52.

  Next, the operation of the management apparatus 10 will be described.

  FIG. 8 is a flowchart showing the operation of the management apparatus 10 from step S20 to step S30, step S60 and step S90 in FIG.

  First, the resource management block 140 determines whether or not relocation processing is necessary based on whether the load amount of the local computer 51 exceeds a predetermined threshold.

  If it is determined that the rearrangement process is necessary, a candidate for the computer 50 to which a part of the process processed by the local computer 51 is newly assigned is selected based on the policy (step S210).

  Next, the resource management block 140 determines whether there is a computer 50 that can be allocated to the application based on the load status of the computer 50 selected as a candidate to be newly allocated to the application (step S220).

  If there is no computer 50 that can be allocated to the application (step S220: NO), the resource management block 140 ends the rearrangement process.

  If there is a computer 50 that can be assigned to the application (step S220: YES), the resource management block 140 instructs the route calculation block 150 to calculate the network route connecting the computer 50 and the local computer 51, and the route The calculation block 150 calculates a network route based on the instruction (step S230).

  The resource management block 140 assigns the remote computer 52, the local computer 51, and the remote computer 52 based on the load status of the network device 30 on the network path calculated by the computer 50 and the path calculation block 150 that can be assigned to the application. Determine the network path to connect to. Further, the resource management block 140 determines a period for allocating the remote computer 52 and the network device 30 on the determined network path (step S240). Note that the resource management block 140 may determine a plurality of computers 50 as remote computers 52.

  Next, the resource management block 140 outputs schedule information indicating the content of the allocation determined by the rearrangement process to the scheduler block 160.

  The scheduler block 160 performs scheduling based on the schedule information, instructs the setting instruction block to request the setting change to the network apparatus 30 that needs to change the communication setting, and the setting instruction block 170 A setting change request is transmitted to (step S300).

  Next, the setting instruction block 170 determines whether or not an ACK has been received from all the network devices 30 that have transmitted the setting change request in Step S300 (Step S310).

  When ACK has not been received from all the network devices 30 (step S310: NO), the setting instruction block 170 repeats the process of step S310.

  When ACK has been received from all the network devices 30 (step S310: YES), the setting instruction block 170 requests notification of the new assignment to the application, setting of the process to be processed and change of communication setting It transmits to the remote computer 52 with the setting change request to perform (step S600).

  Next, the setting instruction block 170 determines whether or not an ACK has been received from all the remote computers 52 that have transmitted the notification in step S600 (step S610).

  When ACK has not been received from all the remote computers 52 (step S610: NO), the setting instruction block 170 repeats the process of step S610.

  When ACK has been received from all the remote computers 52 (step S610: YES), the setting instruction block 170 notifies the scheduler block 160 to that effect, and the remote computer 52 is newly added to the process processed by the local computer 51. A notification indicating that it has been assigned to the remote computer 52 and information related to the remote computer 52 is transmitted to the local computer 51 (step S900).

  Note that the management apparatus 10 can also perform the processing from step S600 to step S610 first before performing the processing from step S300 to step S310.

  The management apparatus 10 can also overlap the processing from step S300 to step S310 and the processing from step S600 to step S610.

  The arithmetic processing block 540 determines whether or not a notification indicating that the remote computer 52 is newly assigned to the process processed by the local computer 51 is transmitted from the management device 10 (step S950).

  Note that a method for determining whether a notification is transmitted from the management apparatus 10 is related to a method in which the local computer 51 polls a specific storage area or a notification transmitted from the management apparatus 10 in the local computer 51. There is a method of determining whether or not a notification is transmitted based on the generated interrupt.

  When the notification is not transmitted from the management apparatus 10 (step S950: NO), the arithmetic processing block 540 repeats the process of step S950.

  When the notification is transmitted from the management apparatus 10 (step S950: YES), the process management block 530 notifies the content of the notification from the management apparatus 10 to the process to be processed by the remote computer 52 (step S950). S960).

  Note that there is a mechanism for receiving a notification from the local computer 51 if the process to be processed in the remote computer 52 is a program described assuming that the process is performed in the distributed computing environment 1. Can be expected to do. In addition, even if such a mechanism does not exist, a library hook mechanism that changes a library, which is a general-purpose program used for process processing, in accordance with the contents of notification from the local computer 51 is introduced. Thus, the computer 50 that processes the process can be changed from the local computer 51 to the remote computer 52 in accordance with the contents of the notification.

  Next, the operation of the network device 30 shown in FIG. 7 will be described.

  FIG. 11 is a flowchart showing the operation of the network device 30 from step S40 to step S50 in FIG.

  The determination as to whether or not a setting change request has been transmitted from the management apparatus 10 can be performed by a method similar to the above-described determination as to whether or not the local computer 51 has transmitted a notification from the management apparatus 10.

  When the setting change request has not been transmitted (step S400: NO), the communication processing block 340 repeats the process of step S400.

  When the setting change request is transmitted (step S400: YES), the communication setting management block 330 changes the communication setting according to the transmitted setting change request (step S410).

  When the setting change is completed, the communication processing block 340 transmits an ACK indicating that fact to the management device 10 (step S500).

  Next, the operation of the remote computer 52 shown in FIG. 7 will be described.

  Note that the determination as to whether or not the notification is transmitted from the management apparatus 10 can be performed by a method similar to the above-described determination as to whether or not the local computer 51 has transmitted a notification from the management apparatus 10.

  When the notification is not transmitted from the management apparatus 10 (step S700: NO), the arithmetic processing block 540 repeats the process of step S700.

  When the notification is transmitted from the management apparatus 10 (step S700: YES), the communication setting management block 520 is transmitted in accordance with the setting change request for requesting the setting of the process to be processed by the own device and the change of the communication setting transmitted with the notification. The process management block 530 performs necessary processing (step S710).

  When the processing by the communication setting management block 520 and the process management block 530 is completed, the arithmetic processing block 540 transmits an ACK indicating that fact to the management device 10 (step S800).

(2) Operation when New Network Device 30 is Assigned to Application FIG. 13 is a sequence diagram showing an operation when a network device 30 is newly assigned to an application by the management system of this embodiment.

  In FIG. 13, the same processes as those in FIG.

  First, the network device 30W monitors the usage status and load status of its own device, and transmits network device monitor information to the management device 10 (step S18).

  The management device 10 determines whether or not the rearrangement process is necessary based on whether the load amount of the network device 30W exceeds the threshold value. If it is determined that relocation processing is necessary, a remote computer 52 to be newly assigned to an application and a network path for connecting the remote computer 52 and a computer that needs to transfer data are determined (step S20). ).

  Then, the management apparatus 10 sends a notification that the remote computer 52 has been newly assigned to the process processed by the local computer 51, along with a setting change request for requesting a change in the setting of the process to be processed and a change in the communication setting. It transmits to all the computers 50 which need to change a setting (step S60).

(Step S50).

Note that there is no need to newly assign the remote computer 52 and only the network path may be changed. In this case, the processes of steps S60 to S80 are not executed.
(3) Operation when Management Device 10 Requests Transmission of Monitor Information FIG. 14 shows an application based on the transmitted monitor information when the management device 10 according to the management system of this embodiment requests transmission of monitor information. It is a sequence diagram which shows the operation | movement at the time of changing the computer 50 allocated to.

  In FIG. 14, the same processes as those in FIG.

  In the following, a case where the management apparatus 10 requests the computer 50 to transmit computer monitor information will be described as an example. However, the present invention can also be applied to a case where the network apparatus 30 requests transmission of network device monitor information.

  First, the management apparatus 10 transmits an acquisition request for computer monitor information to the local computer 51 through the setting instruction block 170 (step S15).

  When receiving the acquisition request, the local computer 51 transmits computer monitor information to the management device 10 (step S16).

  Based on the transmitted computer monitor information, the management apparatus 10 performs relocation processing when the load amount of the local computer 51 exceeds the threshold value.

  Next, the operation of the local computer 51 shown in FIG. 14 will be described with reference to FIGS. 15 and 16.

  FIG. 15 is a flowchart showing the operation of the local computer 51 in step S16 in FIG.

  First, the local monitor block 550 periodically monitors the load status of the own device.

  Then, the arithmetic processing block 540 determines whether or not an acquisition request for computer monitor information has been transmitted from the management apparatus 10 (step S160).

  If the computer monitor information acquisition request has not been transmitted (step S160: NO), the arithmetic processing block 540 repeats the same processing.

  When an acquisition request for computer monitor information is transmitted (step S160: YES), the arithmetic processing block 540 manages computer monitor information indicating the latest usage status and load status of the own device monitored by the local monitor block 550. It transmits to the apparatus 10 (step S164).

(Step S164).

  In FIG. 16, unlike FIG. 15, the local monitor block 550 monitors the load status of the own device only when an acquisition request is received.

  By doing in this way, the frequency | count of monitoring can be reduced depending on the frequency of transmission of an acquisition request, and the load for monitoring in the local computer 51 can be reduced.

  Therefore, the management device 10 determines the computer 50 and the network device 30 to be newly assigned to the application based on the load status of the computer 50 and the network device 30, so that the load for executing the application can be distributed. It can suppress that the utilization efficiency of the distributed computing environment 1 falls.

(Second Embodiment)
The management system according to the second embodiment of the present invention is different from the management system according to the first embodiment in that the network device 30 is changed to the network device 35.

  Note that the configurations of the computer 50 and the management apparatus 10 are the same as those in the first embodiment, and thus description thereof is omitted.

  First, the operation of the management apparatus 10 will be described.

  The management apparatus 10 sets identification information for data transferred between the computers 50 using the resource management block 140. Then, the management device 10 determines the identification information set for the data in association with the transfer destination of the data for which the identification information is set, or the data among the data for which the identification information is set Set the flow information that defines the identification information for discarding. Then, the management device 10 transmits the set flow information to each network device 35 via the management interface 120.

  The identification information includes the input port of the network device 35, the MAC (Media Access Control) address, the IP (Internet Protocol) address, and the port number of the network device 35 included in the data transferred from the transfer source computer 50. The information is related to the protocol of each layer in the OSI (Open System Interconnection) reference model, such as the application to which the computer 50 is assigned, the specific header or data of the process being processed, and the combination thereof.

  Which information is used for the identification information is determined in advance between the computer 50 and the management apparatus 10.

  Next, the operation of the computer 50 will be described.

  The computer 50 uses the information predetermined with the management device 10 and includes the identification information in the data transferred from the own device and transfers it to the network device 35.

  Next, the configuration of the network device 35 will be described.

  FIG. 17 is a block diagram showing the configuration of the network device 35 in the management system of this embodiment.

  In FIG. 17, the same components as those of the network device 30 shown in FIG.

  The network device 35 shown in FIG. 17 is different from the network device 30 shown in FIG. 3 in that a flow management block 335 is provided instead of the communication setting management block 330.

  The flow management block 335 holds the flow information transmitted from the management apparatus 10.

  When the data is transferred to the communication processing block 340, the communication processing block 340 transfers the data to the transfer destination corresponding to the identification information included in the data based on the flow information set in the flow management block 335. Or discard the data.

  Next, the operation of the network device 35 will be described.

  FIG. 18 is a flowchart showing the operation of the network device 35.

  The communication processing block 340 extracts identification information included in the data transmitted to the own device (step S351). Then, the communication processing block 340 collates the flow information set in the flow management block 335 (step S352), and determines whether or not the identification information included in the extracted data is set in the flow management block 335. (Step S353).

  When the identification information included in the data is set in the flow management block 335 (step S353: YES), the communication processing block 340 transfers or discards the data to the corresponding transfer destination (step S353). S354).

  If the identification information included in the data is not set in the flow management block 335 (step S353: NO), the communication processing block 340 discards the data, transfers it to the standard transfer destination, Processing such as an inquiry to the external device of the data transfer destination is performed (step S355).

  An external device refers to a device such as a management server that manages the processing contents of the data for each data.

  Here, the data transfer operation by the network device 30 of the first embodiment and the network device 35 of the present embodiment will be described with reference to FIGS. 19 and 20.

  First, data transfer by the network device 30 according to the first embodiment will be described.

  FIG. 19 is a diagram for explaining an example of the data transfer operation by the network device 30 according to the first embodiment.

  In FIG. 19, the network device 30 transfers data between the computer 50A and the computer 50B, and between the computer 50A and the computer 50C.

  In FIG. 19, “A → B” of data transferred from the computer 50A to the network device 30 indicates that the data is transferred from the computer 50A to the computer 50B, and is included in the data. It can be identified by the MAC address of the computer 50B.

  Here, in general, the network device 30 transfers data according to the MAC address of the transfer destination included in the data.

  Accordingly, the communication setting of the network device 30 is “transfer data to the computer 50B if the MAC address included in the data indicates the computer 50B, and transfer data to the computer 50C if the MAC address indicates the computer 50C. Is set. Then, according to the communication setting, the network device 30 transfers data based on the MAC address included in the data.

  Here, it is assumed that the assignment is changed by the rearrangement process so that the process processed by the computer 50C is processed by the computer 50D.

  At this time, the management apparatus 10 changes the communication setting of the network apparatus 30 from “transfers data to the computer 50C if the MAC address indicates the computer 50C” to “computer 50D if the MAC address indicates the computer 50D”. Change to "Transfer data to".

  Here, if the computer 50A is not notified that the computer that processes the process has been changed to the computer 50D, the computer 50A continues to transfer data including the MAC address of the computer 50C. Then, the network device 30 cannot transfer the data (A → C) transferred from the computer 50A because the communication setting is not set when the MAC address indicates the computer 50C.

  Therefore, whenever the computer 50A that processes the process is changed, the computer 50A that is the data transfer source is notified of information about the changed computer 50 from the management apparatus 10, and needs to change the communication setting according to the notification. was there.

  Next, data transfer by the network device 35 of the present embodiment will be described.

  FIG. 20 is a diagram for explaining an example of the data transfer operation by the network device 35 of the present embodiment.

  Also in FIG. 20, as in FIG. 19, the network device 35 performs data transfer between the computer 50A and the computer 50B, and between the computer 50A and the computer 50C.

  Then, the management device 10 (not shown) sets the identification information for the data transferred from the computer 50A to the computer 50B via the network device 35 to “flow 1”, and is transferred from the computer 50A to the computer 50B via the network device 35. The identification information for the data to be stored is set as “flow 2”.

  In FIG. 20, “flow 1” of data transferred from the computer 50 </ b> A to the network device 35 indicates that identification information “flow 1” is included in the transferred data.

  Here, the identification information “flow 1” is indicated by a combination of, for example, the IP address of the computer A and information indicating a process that is being processed by the computer 50A and that needs to be transferred to the computer 50B. Further, the identification information “Flow 2” is indicated by a combination of the IP address of the computer 50A and information indicating a process that is being processed by the computer 50A and that requires a process of transferring data between the computer 50C. And As described above, which information is used for the identification information is determined in advance between the computer 50 and the management apparatus 10.

  In addition, the management apparatus 10 sets the flow information in which the transfer destination of data in which the identification information “flow 1” is set as the computer 50B and the transfer destination of data in which the identification information “flow 2” is set as the computer 50C. 35.

  As described above, in the flow information, it is possible to determine identification information for discarding data. However, in FIG. 20, the identification information set for the data and the data for which the identification information is set. It is assumed that the flow information determined in association with the transfer destination is transmitted from the management device 10 to the network device 35.

  Then, the network device 35 sets the transmitted flow information in the flow management block 335.

  The computer 50A includes, in the data to be transferred to the computer 50B, the IP address of the computer 50A indicating the identification information “Flow 1”, and information indicating the process that the computer 50A has processed in parallel with the computer 50B. Are transferred to the network device 35.

  Similarly, the computer 50A indicates the IP address of the computer 50A indicated in the identification information “Flow 2” in the data to be transferred to the computer 50C and the process that the computer 50A has processed in parallel with the computer 50C. Including the information indicating that the data is transferred to the network device 35.

  Based on the flow information set in the flow management block 335, the network device 35 transfers the data to the transfer destination corresponding to the identification information included in the data transferred from the computer 50A.

  Here, it is assumed that the assignment is changed by the rearrangement process so that the process processed by the computer 50C is processed by the computer 50D.

  In this case, the management device 10 transmits a setting change request to the network device 35 so as to change the transfer destination of the data in which the identification information “flow 2” is set from the computer 50C to the computer 50D. In accordance with the setting change request transmitted from the management apparatus 10, the data transfer destination is changed to the computer D.

  Here, even if the computer that processes the process is changed from the computer 50C to the computer 50D, the information indicating the identification information “Flow 2” is the information indicating the IP address of the computer 50A and the process being processed by the computer 50A. Therefore, the computer 50A can transfer the data to the network device 35 as it is without changing the identification information.

  Further, the network device 35 can transfer the data to the computer 50D because the setting of the transfer destination of the data in which the identification information “Flow 2” is set has been changed to the computer 50D.

  As described above, according to the present embodiment, the management apparatus 10 determines the identification information of the data to be transferred between the computers 50 by the network apparatus 35 and the transfer destination of the data in which the identification information is set. Of the data set in association or set with the identification information, the flow information defining the identification information for discarding the data is transmitted to the network device 35.

  In addition, the computer 50 transfers data including identification information to the network device 35 using information predetermined with the management device 10. Then, based on the flow information, the network device 35 transfers the data to the transfer destination corresponding to the identification information included in the data transferred to the own device, or discards the data.

  Therefore, the network device 35 can process the data transferred to the own device even if the data transferred to the own device does not include information indicating the transfer destination of the data.

  The computer 50 that is the data transfer source does not need to change the communication setting even when the assignment of the computer 50 to the application is changed and the data transfer destination is changed.

  Note that the management system according to the present embodiment can also be applied when the database system is operating in the distributed computing environment 1, for example.

  As one form of the database system, there is a form composed of a front end that serves as an interface when a user makes an inquiry to the database system and a back end that actually accesses the database. When the management apparatus 10 of the present embodiment is applied to such a database system, different identification information is set for each user who has accessed the front end, and a part or all of the identification information is set to a different back end. It becomes possible to transfer a request from a user, and load can be distributed.

  The method performed by the management device and the network device of the present invention may be applied to a program for causing a computer to execute. In addition, the program can be stored in a storage medium and can be provided to the outside via a network.
