Detailed Description

The embodiment of the application provides a control method, a control device and related equipment, which are used for improving the efficiency of acquiring a target file by service equipment and reducing the waiting time of the service equipment.

The terms "first," "second," "third," "fourth," and the like in the description and in the claims of the present application and in the drawings described above, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

In the process of starting or operating the current service device, a target file stored in the control device may be acquired from the control device so as to perform normal starting or operating of the service device, and the target file may be a software file such as a patch package or other target files. However, in general, the capability of the control device to process data in parallel is limited, and if a plurality of service devices acquire an object file from one control device at the same time, the downloading efficiency of the object file of the service device is low, for example, the downloading speed is slow due to the acquisition of a plurality of object files at the same time, or the number of object files to be acquired is too large, so that some service devices need to wait. For example, 20 service devices are provided in the network device, and if one control device can simultaneously support 5 service devices to acquire the target file from the control device, the other 15 service devices need to wait for a long time to acquire the target file while the 5 service devices acquire the target file.

In order to solve the foregoing technical problem, embodiments of the present application provide a control system, a method, and a related device, where a service device may obtain a target file from multiple control devices, so that the multiple control devices simultaneously provide the target file under the condition that the capability of the control devices for processing data in parallel is limited, so as to improve the efficiency of obtaining the target file. Specifically, the corresponding first target devices may be allocated to the service devices by obtaining addresses and attribute information of the plurality of control devices, where the first target devices allocated to at least two service devices are different, and the service devices may obtain the target file from the corresponding first target devices. Compared with the prior art in which all the service devices acquire the target file from the same control device, in the control system provided in the embodiment of the present application, the target file is provided for a plurality of service devices through a plurality of control devices at the same time, and under the condition that the capability of the control devices for processing data in parallel is limited, the service devices can acquire the target file through other control devices, so that the waiting time of the service devices is reduced, and the efficiency of the service devices for acquiring the target file is improved. For example, 20 service devices are provided in the network device, if one control device can simultaneously support 5 service devices to obtain the target file from the control device, if the 20 service devices simultaneously obtain the target file from two control devices, each control device corresponds to 5 service devices that are obtaining the target file, and 5 service devices wait to obtain the target file, so that the waiting time of the service devices is reduced, and if the 20 service devices simultaneously obtain the target file from four control devices, each control device corresponds to 5 service devices that are obtaining the target file, so that the target file can be obtained without waiting.

A control system provided in an embodiment of the present application is described in detail below with reference to the accompanying drawings. Referring to fig. 1, a block diagram of a control system provided in an embodiment of the present application is shown, where the control system 100 may include: an address assignment device 101, a plurality of service devices 102, and a plurality of control devices 103.

The control device 103 may be a device for data processing and instruction issuing in a network device, for example, a processor in a network device such as a computer, a switch, a router, a gateway, and the like, and specifically may be a central processing unit or a microprocessor. The control device 103 may be in the form of an integrated circuit, in which case the control device 103 may be a main control board.

The service device 102 is a device that executes the instruction issued by the control device 103, and may be, for example, an interface device for connecting with an external device, or the service device 102 may exist in the form of an integrated circuit, in this case, the service device 102 may be an interface board LPU, a cross board, or the like.

The control device 103 and the service device 102 may have a connection relationship therebetween, which may include a direct connection and an indirect connection. Specifically, if the control device 103 and the service device 102 can directly communicate, it may be considered that the control device 103 and the service device 102 are directly connected, and if the control device 103 and the service device 102 cannot directly communicate, and can realize communication through other devices, it may be considered that the control device 103 and the service device 102 are indirectly connected. For example, refer to fig. 2, which is a schematic diagram illustrating a connection relationship between a control device and a service device in an embodiment of the present application. The first control device and the second control device may be in direct communication with the first service device, the second service device, the third service device, and the fourth service device, respectively, and then the first control device and the second control device are in direct connection with the first service device, the second service device, the third service device, and the fourth service device, respectively, and the third control device may be in direct communication with the first control device and the second control device, then the third control device may be in communication with the first service device, the second service device, the third service device, and the fourth service device, respectively, through the first control device or the second control device, and then the third control device is in indirect connection with the first service device, the second service device, the third service device, and the fourth service device.

A plurality of control devices 103 may have a subordinate relationship therebetween, for example, in the same network device, there may be an active control device and a standby control device. In general, the active control device performs data processing and instruction issuing, and when the active control device fails, a standby control device may replace the active control device to perform data processing and instruction issuing. At this time, the standby control device is a slave device of the active control device.

The plurality of service devices 102 are usually in a parallel relationship, and respectively execute the instructions issued by the control device 103, taking an interface board as an example, different interface boards may connect different external devices, and the plurality of interface boards may be independent of each other.

As an example, referring to fig. 3, the network device includes 2 cluster central boxes (CCCs) and 8 cluster line-card boxes (CLC), where the cluster central boxes may manage the cluster line-card boxes and implement data exchange with the cluster line-card boxes. The cluster line card frame comprises 2 MPU boards and 16 LPU boards, wherein the 2 MPU boards are respectively a main control board of the cluster line card frame and a standby main control board of the cluster line card frame, and the 16 LPU boards are used as interface boards and are used for connecting external equipment; the cluster central frame also comprises 2 MPU boards and 8 ECU boards, wherein the 2 MPUs are respectively used as a main control board of the cluster central frame and a standby main control board of the cluster central frame, and the 8 ECUs are used as interface boards and are used for connecting external equipment comprising a cluster line card frame.

The address assigning apparatus 101 may be the control apparatus 103, or may be a processor other than the control apparatus 103 in the network apparatus. That is, the address assigning apparatus 101 may or may not be included in the plurality of control apparatuses 103. A Running Packet Manager (RPM) may be deployed on the address assignment device 101, and the address assignment device 101 may implement address assignment through the running packet manager.

The address assignment device 101 may be configured to assign corresponding first target devices to the service device 102 from the plurality of control devices 103, respectively, according to the attribute information of the plurality of control devices 103. The attribute information of the control device 103 may include at least one of a connection relationship between the control device 103 and the service device 102, an affiliation relationship between the plurality of control devices 103, a number of currently occupied resources of the plurality of control devices 103, and/or a number of currently idle resources.

For the connection relationship between the control device 103 and the service device 102 and the subordinate relationship between the plurality of control devices 103, reference may be made to the above description, which is not repeated herein.

The number of resources currently occupied by the plurality of control devices 103 refers to the number of unavailable resources of the current control device 103, and may be the number of resources occupied by the control device 103 sending a target file to the service device, the number of resources occupied by the control device 103 in the process of running a program, or the number of resources occupied under other conditions, which is not limited herein. The number of resources currently occupied by the control device 103 is related to the number of traffic devices communicating with the control device 103 and even to the number of other devices communicating with the control device 103. The number of resources currently occupied by the control device 103 may be represented by a bottom link message amount of the control device 103, or may be represented by a bandwidth occupation situation or a thread occupation situation of the control device 103.

The number of resources currently idle by the control device 103 refers to the number of available resources of the control device 103, and may be determined by the total number of resources of the control device 103 and the number of currently occupied resources. The characterization manner of the currently idle resource quantity of the control device 103 may be similar to the currently occupied resource quantity of the control device 103, for example, may be characterized by an achievable bottom-layer link message quantity and a used bottom-layer link message quantity of the control device 103, or may be characterized by a bandwidth idle condition or a thread idle condition of the control device 103. As an example, the total bandwidth of the control device 103 is 10M, the currently occupied bandwidth is 5M, and the currently idle bandwidth is 5M. As another example, a control device may have at most 10 threads to send a target file to 10 service devices in parallel, where 5 threads are currently occupied, and 5 threads are currently idle.

The specific process of allocating, by the address allocating apparatus 101, the corresponding first target apparatus to the service apparatus 102 from the plurality of control apparatuses 103 according to the attribute information of the plurality of control apparatuses 103 may be determined according to different attribute information.

As a possible implementation manner, if the attribute information of the multiple control devices 103 only includes the connection relationships between the multiple control devices 103 and the service devices 102, the address assignment device 101 may assign corresponding first target devices to the service devices 102 from the multiple control devices 103 according to the connection relationships between the multiple control devices 103 and the service devices 102. As a possible implementation manner, the address assignment device 101 may preferentially assign a control device with a closer connection relation to the service device 102 as a first target device corresponding to the service device 102, so as to simplify a communication path between the service device 102 and the corresponding first target device and improve communication efficiency, for example, a control device directly connected to the service device 102 may be used as the first target device.

As another possible implementation manner, if the attribute information of the plurality of control devices 103 includes the dependencies between the plurality of control devices 103, the address assignment device 101 may assign the corresponding first target devices to the service device 102 from the plurality of control devices 103 according to the dependencies between the plurality of control devices 103. As a possible implementation manner, the address allocating device 101 may preferentially allocate the slave control device to the service device 102 as the first target device corresponding to the service device 102, because the slave control device is not generally used for processing other transactions, the occupied resource quantity is generally small, and the slave control device is taken as the first target device corresponding to the service device 102 to reduce the influence on the master control device due to the connection with the first target device, for example, the standby control device may be taken as the first target device corresponding to the service device 102.

As another possible implementation manner, if the attribute information of the plurality of control devices 103 includes the number of resources currently occupied by the plurality of control devices 103, the address allocation device 101 may allocate corresponding first target devices to the service device 102 from the plurality of control devices 103 according to the number of resources currently occupied by the plurality of control devices 103. For example, the address allocating device 101 may preferentially allocate a control device with a smaller number of currently occupied resources to the service device 102 as a first target device corresponding to the service device 102.

As another possible implementation manner, if the attribute information of the multiple control devices 103 includes the number of resources currently idle by the multiple control devices 103, the address assignment device 101 may assign, according to the number of resources currently idle by the multiple control devices 103, corresponding first target devices to the service device 102 from the multiple control devices 103, respectively. For example, the address allocating device 101 may preferentially allocate a control device with a larger number of currently idle resources to the service device 102, as the first target device corresponding to the service device 102.

Of course, the attribute information of the plurality of control devices 103 may also include: the connection relationship between the plurality of control devices 103 and the service device 102, and the subordinate relationship between the plurality of control devices 103. At this time, the address allocating device 101 allocates corresponding first target devices to the service device 102 from the plurality of control devices 103 according to the attribute information of the plurality of control devices 103, which may specifically be: the address assignment device 101 determines, from the plurality of control devices 103, a control device that is closer to the connection relationship with the service device 102 and is a standby control device as a first target device corresponding to the service device 102, and may determine, for example, a standby main control board directly connected to the service device 102 as the first target device corresponding to the service device 102.

Of course, the attribute information of the plurality of control devices 103 may also include: the connection relationship between the plurality of control devices 103 and the service device 102, and the number of resources currently occupied by the plurality of control devices 103. At this time, the address allocating device 101 allocates corresponding first target devices to the service device 102 from the plurality of control devices 103 according to the attribute information of the plurality of control devices 103, which may specifically be: the address allocating device 101 determines, from the multiple control devices 103, a control device that is closer to the connection relationship with the service device 102 and has a smaller number of currently occupied resources, as a first target device corresponding to the service device 102, for example, a standby main control board directly connected to the service device 102, which generally has a smaller number of occupied resources and has a closer connection relationship with the service device 102, and thus can be used as the first target device corresponding to the service device 102.

While combinations of multiple attribute information of the multiple control devices 103 are listed above, it is understood that in the embodiment of the present application, the attribute information of the multiple control devices 103 may further include other combinations of the above four attribute information, and the address assignment devices 101 may each determine based on the characteristics of each attribute information corresponding to each combination, which is not illustrated herein.

It should be noted that, in the embodiment of the present application, the first target devices to which at least two service devices 102 are allocated are different, that is, all the service devices 102 do not correspond to the same control device.

The address assignment device 101 may also perform acquisition of attribute information of the control device 103 before assigning the corresponding first target device to the service device 102. The attribute information of the plurality of control devices 103 is acquired, and specifically, the attribute information query request is sent to the plurality of control devices 103, and the respective attribute information sent by the plurality of control devices 103 is received. It can be understood that, if the attribute information is static information such as connection relationships between the plurality of control devices 103 and the plurality of service devices 102, or dependency relationships between the plurality of control devices 103, the attribute information of the plurality of control devices 103 may be obtained specifically as follows: the attribute information of the plurality of control devices 103 is stored in advance, and the attribute information of the plurality of control devices 103 is searched.

In this embodiment, before acquiring the attribute information of the plurality of control devices 103, an address assignment request sent by the service device 102 may also be received. Therefore, the attribute information of the plurality of control devices 103 may be specifically acquired as follows: attribute information of the plurality of control devices 103 is acquired in real time in response to an address assignment request sent by the service device 102.

The address allocating device 101 may further obtain the address of the control device 103 before allocating the corresponding first target device to the service device 102. The addresses of the plurality of control devices 103 may be physical addresses of the plurality of control devices 103 for enabling communication of the control devices 103 with other devices. Specifically, the address inquiry request may be transmitted to the plurality of control devices 103, and the respective addresses transmitted by the plurality of control devices 103 may be received, or the addresses of the plurality of control devices 103 may be stored in advance. The attribute information of the plurality of control devices 103 may be acquired specifically as follows: the addresses of the plurality of control devices 103 are acquired in real time in response to an address assignment request sent by the service device 102. For the purpose of acquiring the target file to the control device 103, the physical addresses of the plurality of control devices 103 include an address in which the target file is stored.

The address allocating device 101 may send the address of the corresponding first target device to the service device 102 after allocating the corresponding first target device to the service device 102. Specifically, the address of the first target device may be searched from the addresses of the plurality of control devices 103, and then the address of the first target device may be sent to the service device 102. It is understood that, if the address assignment device 101 is indirectly connected to the service device 102, the address assignment device 101 may receive, through another device directly connected to the service device 102, the address assignment request sent by the service device 102, and send the address of the corresponding first target device to the service device 102.

The service device 102 may be configured to, after receiving the address of the first target device sent by the address assignment device 101, obtain the target file stored in the first target device according to the corresponding address of the first target device.

As a possible target file obtaining manner, referring to fig. 4, the obtaining, by the service device, the target file stored in the first target device according to the address of the corresponding first target device may specifically be: (1) the service equipment sends a file acquisition request to the first target equipment according to the address of the first target equipment, wherein the file acquisition request comprises a file identifier of a target file; (2) and the first target equipment sends the corresponding target file to the service equipment according to the file identification of the target file in the file acquisition request.

As another possible target file obtaining manner, referring to fig. 5, the obtaining, by the service device, the target file stored in the first target device according to the address of the corresponding first target device may specifically be: (1) the service equipment sends a file list acquisition request to the first target equipment according to the address of the first target equipment; (2) the first target equipment sends a stored file list to the service equipment according to the file list acquisition request, wherein the file list carries file identification of the file stored by the first target equipment; (3) the service equipment determines a file identifier of a target file according to a file identifier carried in the file list and a file identifier stored by the service equipment, and sends a file acquisition request to the first target equipment, wherein the file acquisition request carries the file identifier of the target file; (4) and the first target equipment determines the target file according to the file identifier of the target file in the target file acquisition request and sends the corresponding target file to the service equipment.

In addition, in order to improve the accuracy of acquiring the target file, the service device 102 may be further configured to check the acquired target file after the target file is acquired. Specifically, the service device 102 may be deployed with a run-time package management local service (RPMLS). Through checking the target file, the availability of the target file can be determined, so that the available target file can be obtained in time when the target file is damaged, and the influence on the use of the target file by the service device due to the damaged target file obtained by the service device 102 is avoided.

Before verifying the target file, the service device 102 may be further configured to obtain a check code of the target file from the first target device, where the check code of the target file is used to detect whether the target file is in error during transmission. The check code may be a HASH (HASH) value, or may be in other forms, such as a digital signature or a message digest algorithm (MD) fifth version (MD5), and the like, which is not limited herein.

Correspondingly, the first target device is configured to send the check code of the target file to the service device 102, specifically, the first target device may send the check code of each file simultaneously when sending the file list to the service device, or the first target device may send the check code of each target file simultaneously when sending the target file to the service device 102, or the first target device may send the check code of the target file to the service device 102 separately.

After the target file and the check code thereof are obtained, the service device 102 may also be configured to check the target file according to the check code of the target file. Specifically, a check code of the target file may be generated according to the target file, and it is determined whether the check code acquired from the first target device is the same as the check code generated according to the target file, if the check code is the same, it indicates that the target file is acquired correctly, the check is passed, and if the check code is different, it indicates that the target file is acquired incorrectly, the check is not passed. For example, a first HASH value of the target file may be obtained from the first target device, and a second HASH value of the target file may be generated according to the obtained target file, where if the first HASH value and the second HASH value are different, it indicates that an error occurs in the target file during transmission.

When the service device 102 passes the verification of the target file, it indicates that the target file is available, and the service device 102 may execute a corresponding process according to the obtained target file.

When the service device 102 fails to verify the target file, it indicates that the target file is damaged, and at this time, the service device 102 is further configured to send an address redistribution request to the address distribution device 101, so that the address distribution device 101 performs redistribution on the control device 103 according to the address redistribution request.

Correspondingly, the address allocating device 101 is further configured to receive an address re-distribution request sent by the service device 102, match a corresponding second target device for the service device 102 from the control devices 103 except the first target device matched with the service device 102 according to the received address re-distribution request and attribute information of the plurality of control devices 103, and send an address of the second target device to the service device 102, so that the service device 102 obtains a target file stored in the second target device according to the address of the second target device. In a specific process, the address assignment device 101 may be referred to assign a corresponding first target device to the service device 102, and send an address of the first target device to the service device 102, so that the service device 102 obtains a target file stored in the first target device according to the address of the first target device.

For ease of understanding, the following describes the process of acquiring the object file with reference to a specific scenario. The service device 102 may take one of the interface boards as an example, the control device 103 may take a main control board as an example, the main control board includes a first main control board and a second main control board, and the address allocation device 101 is another device except the control device 103.

Referring to fig. 6, the process of acquiring the target file may specifically be:

(1) the interface board sends an address allocation request to the address allocation equipment;

(2) the address allocation equipment allocates a corresponding first main control board for the interface board from the plurality of main control boards according to the attribute information of the plurality of main control boards, and sends the address of the first main control board to the interface board;

(3) the interface board sends a file list acquisition request to the first main control board;

(4) the first main control board sends a file list stored by the first main control board to the interface board;

(5) the interface board determines a target file from the file list and sends a target file acquisition request to the first main control board, wherein the target file acquisition request comprises an identifier of the target file;

(6) the first main control board sends a first target file and a check code of the first target file to the interface board according to the target file acquisition request;

(7) the interface board checks the first target file, starts or updates according to the first target file when the first target file passes the check, and ends the target file acquisition process; when the verification fails, executing the step (8);

(8) sending an address redistribution request to the address distribution equipment;

(9) the address redistribution equipment determines a second main control board corresponding to the interface board from other main control boards except the first main control board according to the attribute information of the plurality of main control boards, and sends the address of the second main control board to the interface board;

(10) the interface board sends a file list acquisition request to the second main control board;

(11) the second main control board sends a file list to the interface board;

(12) the interface board determines a target file from the file list and sends a target file acquisition request to the second main control board, wherein the target file acquisition request comprises an identifier of the target file;

(13) the second main control board sends a second target file and a check code of the second target file to the interface board according to the target file acquisition request;

(14) the interface board checks the second target file, starts or updates according to the second target file when the second target file passes the check, and ends the target file acquisition process; and (5) when the verification fails, referring to the step (8), allocating a third main control board for the interface board.

In actual operation, the priority of the first target device may also be determined, and when the first target file of the optimal first target device is damaged, the suboptimal first target device is used as the second target device, and the address of the second target device is sent to the service device. As an example, the priority may be: in the same way, when the target file stored in the second target device is damaged, the standby control device indirectly connected with the service device can be used as a third target device, or when the target file stored in the third target device is damaged, the main control device indirectly connected with the service device can be used as a fourth target device.

When the service equipment fails to verify the target file, the file stored in the control equipment for acquiring the target file can be detected, the control equipment is subjected to fault marking, and the control equipment with the fault marking is not redistributed when the corresponding control equipment is subsequently distributed to the service equipment.

For the control device with the fault flag, the storage file may be repaired or retrieved, and specifically, the control device may be restarted, so as to update the storage file in the control device. After the update of the storage file, the failure flag of the control device may be deleted. When the stored target files of all the control devices have a failure, all the control devices may be restarted so as to update the stored files in the control devices.

In the control system provided by the embodiment of the application, the service device can acquire the target file from the plurality of control devices, so that the target file is simultaneously provided by the plurality of control devices under the condition that the capability of the control devices for processing data in parallel is limited, and the acquisition efficiency of the target file is improved. Specifically, the address allocation device may allocate corresponding first target devices to the service devices according to the attribute information of the plurality of control devices, where the first target devices allocated to at least two service devices are different, and the service devices may obtain the target file from the corresponding first target devices. Compared with the prior art in which all the service devices acquire the target file from the same control device, in the control system provided in the embodiment of the present application, the target file is provided for a plurality of service devices through a plurality of control devices at the same time, and under the condition that the capability of the control devices for processing data in parallel is limited, the service devices can acquire the target file through other control devices, so that the waiting time of the service devices is reduced, and the efficiency of the service devices for acquiring the target file is improved.

Based on the control system provided by the embodiment of the application, the embodiment of the application also provides a control mode, and the specific implementation process can refer to the control system. The execution main body of the control method provided by the embodiment of the application is the address allocation device, which may be one of the plurality of control devices, or may be another processing device independent of the plurality of control devices.

Referring to fig. 7, a flowchart of a control method provided in an embodiment of the present application may include the following steps.

The control device may be a device for data processing and instruction issuing in a network device, for example, a processor in a network device such as a computer, a switch, a router, a gateway, and the like, and specifically, may be a central processing unit or a microprocessor. The control device may be in the form of an integrated circuit, in which case the control device may be a main control board.

The service device is a device that executes an instruction issued by the control device, and may be, for example, an interface device for connecting with an external device, or the service device may exist in the form of an integrated circuit, in this case, the service device may be an interface board, such as an LPU board, an electrical cross board (ECU), and the like.

The attribute information of the control device may include at least one of a connection relationship between the control device and the service device, an affiliation relationship between the plurality of control devices, a number of resources currently occupied by the plurality of control devices, and a number of resources currently free.

Specifically, the connection relationship between the control device and the service device may include a direct connection and an indirect connection. If the control device and the service device can directly communicate, the control device and the service device can be considered to be directly connected, and if the control device and the service device cannot directly communicate, the control device and the service device can be considered to be indirectly connected, and if the control device and the service device can not directly communicate, the communication can be realized through other devices.

Specifically, in the same network device, the standby control device is a slave device of the active control device.

The number of resources currently occupied by the plurality of control devices refers to the number of unavailable resources of the current control devices, and may be the number of resources occupied by the control devices sending the target files to the service devices, the number of resources occupied by the control devices in the process of running the program, or the number of resources occupied under other conditions. The number of the currently occupied resources of the plurality of control devices can be represented by the message quantity of the bottom link of the control devices, and can also be represented by the bandwidth occupation condition or the thread occupation condition of the control devices.

The number of the currently idle resources of the control device refers to the number of the currently available resources of the control device, and may be determined by the total number of the resources of the control device and the number of the currently occupied resources, and may be characterized by the bottom link message amount of the control device, or may be characterized by the bandwidth idle condition or the thread idle condition of the control device.

In this embodiment of the present application, before acquiring attribute information of a plurality of control devices, an address assignment request sent by a service device may also be received. Therefore, the obtaining of the addresses and the attribute information of the plurality of control devices may specifically be: and responding to an address allocation request sent by the service equipment, and acquiring the addresses and attribute information of the plurality of control equipment in real time.

According to the attribute information of the plurality of control devices, the specific process of respectively allocating the corresponding first target device to the service device from the plurality of control devices can be determined according to different attribute information. In particular, reference may be made to the allocation process in the control system.

It should be noted that, in the embodiment of the present application, the first target devices to which at least two service devices are allocated are different, that is, all the service devices do not correspond to the same control device.

After the corresponding first target device is allocated to the service device, an address of the corresponding first target device may be sent to the service device. Specifically, the address of the first target device may be searched from the addresses of the plurality of control devices, and then the address of the first target device may be sent to the service device.

After the service device receives the address of the first target device sent by the address allocation device, the target file stored in the first target device may be acquired according to the corresponding address of the first target device.

In addition, in order to improve the accuracy of obtaining the target file, after the service device obtains the target file, the obtained target file may be checked, specifically, the check may be performed by a function module arranged in the service device, for example, a local service (RPMLS) for operating packet management.

Specifically, when the service device acquires the target file from the first target device, the service device may simultaneously acquire the check code of the target file from the first target device, and check the target file according to the check code of the target file.

When the service device passes the verification of the target file, the target file is indicated to be available, and the service device can be started or updated according to the obtained target file.

When the service equipment does not pass the verification of the target file, the target file is damaged, and at this time, an address redistribution request can be sent to the address distribution equipment, so that the address distribution equipment redistributes the control equipment according to the address redistribution request. Specifically, the address allocating device receives an address re-allocating request sent by the service device, and may match a corresponding second target device for the service device from the control devices except the first target device matched with the service device according to the received address re-allocating request and attribute information of the plurality of control devices, and send an address of the second target device to the service device, so that the service device obtains a target file stored in the second target device according to the address of the second target device. The specific process may refer to a process of allocating a corresponding first target device to the service device, and sending an address of the first target device to the service device, so that the service device obtains the target file stored in the first target device according to the address of the first target device.

When the service equipment fails to verify the target file, the file stored in the control equipment for acquiring the target file can be detected, the control equipment is subjected to fault marking, and the control equipment with the fault marking is not redistributed in the distribution process of the control equipment corresponding to the subsequent service equipment.

In the control method provided by the embodiment of the application, the service device can acquire the target file from the plurality of control devices, so that the target file is simultaneously provided by the plurality of control devices under the condition that the capability of the control devices for processing data in parallel is limited, and the acquisition efficiency of the target file is improved. Specifically, the corresponding first target devices may be allocated to the service devices according to the attribute information of the plurality of control devices, where the first target devices allocated to at least two service devices are different, and the service devices may obtain the target file from the corresponding first target devices.
