Referring to fig. 4, a flowchart of a service management method according to an embodiment of the present invention is shown, and this embodiment illustrates that the service management method is applied to the implementation environment shown in fig. 1, and the service management method can be executed by the service management device. Referring to fig. 4, the service management method includes:

step 201, the service management device sends a service discovery request to a plurality of service providing devices, where the service discovery request is used to request a service providing device with service providing capability to provide service information, and the service information includes types of services provided and access addresses corresponding to each type of service.

In summary, in the service management method provided in the embodiment of the present invention, the service management device automatically sends the service discovery request to the service providing device in the service providing system, and records the service information of the service providing device that sends the service discovery response, so that the service providing device that has recorded the service information can provide services for the application device, and therefore, the service management device automatically discovers the service providing device without querying an IP address by an application platform, and the discovery efficiency of the service providing device is improved.

Referring to fig. 5, a flowchart of another service management method provided by an embodiment of the invention is shown, where the service management method can be applied to any of the implementation environments shown in fig. 1 to 3. Referring to fig. 5, the service management method may be performed by the service management apparatus described above, and the method includes:

step 301, the service management device sends a service discovery request to the plurality of service providing devices, where the service discovery request is used to request the service providing device with the service providing capability to provide service information.

The service information includes types of services to be provided, and access addresses corresponding to each type of service.

For example, the access address may be a Uniform Resource Locator (URL), where the URL includes information of a port accessing a corresponding type of service, and a corresponding relationship between the type of service and each port of the service providing device may be obtained according to the URL of each type of service.

Optionally, the service management device obtains an IP address of the service providing device in the service providing system, and sends a service discovery request to the obtained IP address.

In an optional mode, the service management device stores an address list in advance, the address list records an IP address of the service providing device in the service providing system, and when the service management device performs service discovery, the service management device acquires the address list to acquire the IP address of the service providing device; in another alternative, the service management device may use a preset algorithm (e.g., a web crawler algorithm) to retrieve the IP addresses of the service providing devices in the service providing system, so as to obtain the IP addresses of the service providing devices, and establish a corresponding address list. It should be noted that the address list may also be updated and maintained by a worker, for example, adding or deleting IP addresses therein.

In an embodiment of the present invention, there may be multiple ways for the service management device to send the service discovery request to the multiple service providing devices, and in a first optional way, when the service providing system includes one service providing device, the address list records an IP address of the one service providing device, and then the service management device directly sends the service discovery request to the IP address of the one service providing device.

In a second optional manner, when the service providing system includes multiple service providing devices and multiple IP addresses of the multiple service providing devices all belong to the same network segment, the service discovery request may be directly sent to the multiple IP addresses respectively, or a gateway address corresponding to the multiple IP addresses is obtained and the service discovery request is sent to the gateway address; when the service discovery response corresponding to the gateway address is not received, determining that the gateway fails, and stopping sending service discovery requests to the plurality of IP addresses; and when receiving a service discovery response corresponding to the gateway address, determining that the gateway does not have a fault, and respectively sending service discovery requests to the IP addresses.

In a third optional manner, when the service providing system includes a plurality of service providing devices, and at least two IP addresses in a plurality of IP addresses of the plurality of service providing devices belong to different network segments, the service management device obtains at least two IP address sets. For each IP address set, acquiring a gateway address corresponding to a network segment to which the IP address set belongs, and sending a service discovery request to the gateway address; when the service discovery response corresponding to the gateway address is not received, determining that the gateway fails, and stopping sending the service discovery request to the IP address in the IP address set; and when receiving a service discovery response corresponding to the gateway address, determining that the gateway does not have a fault, and sending a service discovery request to the IP address in the IP address set.

When at least two IP addresses in a plurality of IP addresses of a plurality of service providing devices belong to different network segments, the IP addresses of the plurality of IP addresses belonging to the same network segment are divided into one IP address set, and each network segment corresponds to one gateway. The dividing action may be performed by the service management apparatus or may be performed manually. For example, the service management device divides IP addresses of which a plurality of IP addresses belong to the same network segment into one IP address set to obtain at least two IP address sets, where each network segment corresponds to one gateway.

For example, the IP addresses recorded in the address list in the service management device are 192.167.255.200, 192.167.255.254, 192.168.250.255 and 192.168.250.235, respectively, the corresponding subnet masks are 255.255.225.0, the IP address range to which these four IP addresses belong includes two network segments, 192.167.255.1-192.167.255.254 and 192.168.250.1-192.168.250.254, respectively, the network segments 192.167.255.1-192.167.255.254 correspond to the gateway 1, the gateway address thereof is 192.167.255.1, the network segments 192.168.250.1-192.168.250.254 correspond to the gateway 2, and the gateway address thereof is 192.168.250.1, wherein 192.167.255.200 and 192.167.255.254 belong to the network segments corresponding to the gateway 1, 192.168.250.255 and 192.168.235 belong to the network segments corresponding to the gateway 2.

Then, the service management device sends a service discovery request to the gateway address of the gateway 1, if a service discovery response to the service discovery request is not received, the service management device determines that the gateway 1 fails, and does not need to send the service discovery request to the IP address of the service providing device in the network segment corresponding to the gateway 1, and then sends the service discovery request to the gateway address of the gateway 2, and if a service discovery response to the service discovery request is received, continues to send the service discovery requests to the IP addresses of the service providing devices in the network segment corresponding to the gateway in sequence.

In practical implementation, each network segment corresponds to one gateway, and the gateway is used for maintaining the IP address of the corresponding network segment and executing information transceiving of each service providing device indicated by the IP address of the corresponding network segment, that is, each service providing device in the network segment managed by the gateway. When the gateway fails, all the service providing devices indicated by all the IP addresses in the network segment maintained by the gateway cannot receive and transmit information. Of course, the service providing device cannot respond to the service discovery request. Therefore, before sending the service discovery request to the service providing device, the service management device sends the service discovery request to the gateway address corresponding to the network segment to which the service management device belongs, and then determines whether to send the service discovery request to the service providing device subsequently based on whether the gateway responds to the service discovery request. Therefore, if the gateway fails, the service discovery request does not need to be sent to the service providing equipment managed by the gateway again, the service discovery efficiency is improved, and the network overhead is saved.

In the embodiment of the present invention, there may be multiple ways for the service management device to send the service discovery request to each network segment, for example, in the first way, the service management device may send the service discovery request to the network segment in sequence, that is, perform polling on the network segment. For another example, in the second mode, the service management device sends the service discovery request to a plurality of network segments simultaneously, that is, the service management device sends the service discovery request to the plurality of network segments in batches in multiple threads. In the two manners, the manner of sending the service discovery request to each network segment may refer to the third optional manner of sending the service discovery request. Of course, there may be multiple ways for the service management device to send the service discovery request, as long as it is ensured that each IP address in the address list is traversed finally, which is not limited in the embodiment of the present invention.

Further optionally, the service management device may periodically perform the above-mentioned process of sending the service discovery request, so that information of the service providing device capable of providing the service may be periodically updated; the service discovery request can also be sent when a specified trigger condition is reached, for example, the specified trigger condition is a service discovery instruction triggered by a manager, so that service discovery can be performed in time according to actual requirements. Alternatively, the service management device may be integrated with a plurality of functions, for example, an application registration function, a service registration function, and the like, in addition to the service discovery function. Assuming that the service discovery function of the service management device corresponds to the designated port, the service management device may send a service discovery request to an address indicated by each IP segment in the at least one IP segment through the designated port. The designated port may be a predefined port on the service management device, and the port may be a port that is agreed with each device in the service providing system when the service providing system is networked. The port function of the service management equipment is predefined, which is beneficial to the port standardization of the service management equipment and is convenient for the data interaction between the service management equipment and other equipment.

Step 302, the service management device receives a service discovery response for the service discovery request, where the service discovery response includes service information.

As shown in step 301, the service discovery response sent by the service providing device carries service information of the service providing device, for example, when the service providing device can provide multiple types of services, the service information may include types of services provided by the service providing device and access addresses corresponding to each type of service. When the service providing apparatus can provide a type of service, the service information may include the type of the service and an access address corresponding to the service.

For example, the service management device receives a service discovery response for the service discovery request sent by the service providing device a, where the content of the service discovery response may be "providing a face one-to-one comparison service, and a URL of the comparison service is http:// xx.xx.xx.xx/10; providing face picture quality scoring service, wherein the URL of the scoring service is http:// XX.XX.XX/11; and providing a human body attribute detection service, wherein the URL of the detection service is http:// XX.XX.XX/12."

Step 303, the service management device records the service providing device from which each received service discovery response originates and the carried service information.

When receiving a service discovery response to the service discovery request, it indicates that the communication connection establishment between the service management apparatus and the service providing apparatus that transmitted the service discovery response is successful, and service discovery is achieved. At this time, the service management device may record the service providing device from which each received service discovery response originates (for example, record identification information of the service providing device, where the identification information is used to uniquely identify the device), and the carried service information, where the recorded service providing device is used to provide a service for the application device, and the service management device may screen a corresponding target service providing device from the recorded service providing device when subsequently receiving a service acquisition request of the application device, and provide an intelligent analysis service by the target service providing device. For convenience of explanation, the service providing device recorded by the service management device will be hereinafter referred to as an available service providing device.

It should be noted that, when different service discovery request sending manners are adopted in step 301, the execution process of step 303 is also different accordingly.

Illustratively, when the request is sent in the first optional manner in step 301, the service providing system includes a service providing device, and when receiving the service discovery response sent by the service providing device, records the service providing device and the carried service information.

When step 301 sends a request in a second optional manner, when directly sending a service discovery request to each of the plurality of IP addresses, if a service discovery response sent by any service providing device is received, recording the service providing device and the carried service information; when a service discovery request is sent to a gateway address, if a service discovery response sent by the gateway address is received, it is determined that the gateway does not fail, and then service discovery requests are sent to the multiple IP addresses respectively, and if a service discovery response sent by any service providing device is received, the service providing device and carried service information are recorded.

When step 301 sends the request in a third alternative way, for each set of IP addresses, a service discovery and registration procedure is performed, which comprises: after a service discovery request is sent to a corresponding gateway address, if a service discovery response sent by the gateway address is received, it is determined that the gateway does not fail, and then when the service discovery request is sent to an IP address in an IP address set, if a service discovery response sent by any service providing device is received, the service providing device and the carried service information are recorded, and it is determined that the service providing device can provide services. And if the service discovery response sent by a certain service providing device is not received, determining that the service providing device cannot provide the service. At this time, the next IP address set of the IP address set is acquired as a new IP address set, and the above-described service discovery and registration process is performed again. If the service discovery response sent by the gateway address is not received and the gateway is determined to have a fault, the service discovery and registration process aiming at the next IP address set can be continuously executed until the service discovery and registration process is completed after the IP address set is completely executed.

Optionally, the service management device may maintain an intelligent service list for all available service providing devices, where the intelligent service list is used to record identification information, such as an IP address, of each available service providing device, so that the service management device may detect, through a heartbeat mechanism, whether each available service providing device reaches a logout condition.

The intelligent service list may further record service information corresponding to each identification information (such as an IP address), so that the service management device may determine service information of each available service providing device based on the intelligent service list, for example, determine a service type that it may provide.

Step 304, the service management device obtains capability information of each type of service provided by each available service providing device.

The capability information is used to reflect service capabilities of the corresponding service. The capability information may include information of at least one service capability parameter. Optionally, the at least one service capability parameter includes at least one of an analysis channel number, an algorithm library capability index, and a single channel unit time analysis capability index. The available service providing apparatus is a recorded service providing apparatus.

For each type of service provided by each available service providing device, the number of analysis channels refers to the number of analysis channels providing the type of service, the analysis channels refer to channels used by the service providing device for performing the type of service, and each service providing device may set at least one analysis channel for each type of service to be provided by the service providing device. For each type of service, when one service providing device sets a plurality of analysis channels, the plurality of analysis channels can provide the service in parallel, that is, the data carried in a plurality of service acquisition requests of the same type of service are analyzed in parallel; the algorithm library is used to provide a number of functions for intelligent analysis services, such as lookup functions, ranking functions, counting functions, or manipulation functions. For a type of service, the algorithm library capability index is used for expressing the capability of the algorithm library providing the type of service to process data in a unit time length; for any type of M service provided by the available service providing device, the single-channel analysis capability per unit time index is the amount of data that can be analyzed by the target analysis channel in a unit time duration, and the amount of data can be reflected by the number of service acquisition requests received by the analysis channel. The target analysis channel is an analysis channel for analyzing data corresponding to any type of M service.

In the embodiment of the present invention, for different service capability parameters, the corresponding capability information is obtained in different manners, and the following conditions of the service capability parameters are taken as examples in the embodiment of the present invention for explanation:

in a first case, when at least one service capability parameter includes at least one of the number of analysis channels and the algorithm library capability index, for each registered service providing device, the service management device may send a service capability parameter obtaining request to the available service providing device, and after receiving the service capability parameter obtaining request, the available service providing device generates a service capability parameter response based on the service capability parameter obtaining request, where the service capability parameter response includes the at least one service capability parameter of all types of services provided in the available service providing device. Optionally, in step 303, the service information may further include at least one of an analysis channel number and an algorithm library capability index of all types of services provided in the available service providing device. Therefore, the service management equipment does not need to independently acquire the service capability parameters from the available service providing equipment, the occupation of network resources in the service providing system is reduced, and the network overhead is saved.

In a second case, when at least one service capability parameter includes a single channel time analysis capability index, as shown in fig. 6, in an embodiment of the present invention, it is assumed that a single channel time analysis capability index of a first type of service needs to be acquired, where the first type is any service type supported by a first service providing device, and the first service providing device is any device in all available service providing devices, an information acquisition process of the service capability parameter may include:

step 3041, for the first type of service, the service management device generates at least one simulated service acquisition request, where each simulated service acquisition request carries data to be analyzed of the first type.

For example, the service management device may assume that there is a first type of intelligent analysis that the application device needs to perform on data, that is, a first type of service is needed, the service management device generates at least one simulated service acquisition request, generally, each simulated service acquisition request carries one piece of data to be analyzed, the piece of data to be analyzed includes a specified number of parameters to be analyzed, the specified number of parameters to be analyzed is data that is obtained by the service management device in advance, and the data to be analyzed may be configured in the service management device manually or by another device, the specified number is related to a service type of the first type of service, and generally, for the same service type, the number of parameters to be analyzed included in the simulated service acquisition request is the same. For example, when the first type of service is face 1V1 comparison, for the first type of service, the service management device generates at least one simulation service acquisition request, where the simulation service acquisition request includes two pieces of face photograph information to be compared, that is, two parameters to be analyzed.

Step 3042, the service management apparatus sends at least one simulated service acquisition request to the first service providing apparatus.

In the embodiment of the present invention, there may be multiple ways for the service management device to send the analog service acquisition request, for example, in the first way, the service management device may send the analog service acquisition request to each available service providing device in sequence, that is, perform polling on the available service providing devices, and for example, in the second way, the service management device sends the analog service acquisition request to multiple available service providing devices of all the available service providing devices at the same time, that is, perform broadcast or multicast of the analog service acquisition request. In a third method, the service management device firstly filters all available service providing devices to obtain a service providing device capable of providing the first type of service, and then sends the analog service acquisition request to the determined service providing device in a polling or multicast or broadcast manner, where the sending process may refer to the first method or the second method.

Of course, there may be various ways for the service management device to send the simulated service acquisition request, as long as it is ensured that the simulated service acquisition request finally traverses all available service providing devices capable of providing the first type of service.

Step 3043, the service providing apparatus receives the simulated service acquisition response for each simulated service acquisition request.

With reference to the three manners in step 3042, since each analog service acquisition request carries the data to be analyzed of the first type, when any available service providing device can provide the service of the first type, the analog service acquisition request can be acquired, the data in the analog service acquisition request can be analyzed, and then an analog service acquisition response is sent after the analysis is completed.

Step 3044, the service providing device calculates a single channel unit time analysis capability index of the first type of service based on the sending time of the at least one analog service acquisition request and the receiving time of the received analog service acquisition response.

For example, the service management device determines, based on the sending time of the at least one simulated service acquisition request and the receiving time of the received simulated service acquisition response, a total analysis duration of the data in the at least one simulated service acquisition request by the corresponding service providing device (i.e., the service providing device that sent the simulated service acquisition response); then, the service management device may divide the number of the analog service acquisition requests by the total analysis time length to obtain the number of the analog service acquisition requests processed by the service providing device for the first type of service within a unit time length; and dividing the number of the analog service acquisition requests by the number of the pre-acquired first type service analysis channels to obtain a single-channel unit time analysis capability index of the first type service.

For example, assuming that the unit time is 1 second, the service management apparatus obtains a single-channel analysis capability index per unit time for the first type of service of one available service providing apparatus a, and the number of analysis channels of the first type of service is 3.

The method comprises the steps that 15 simulation service acquisition requests are generated by service management equipment and sent to available service providing equipment A, the equipment A analyzes data in the 15 simulation service acquisition requests and returns corresponding simulation service acquisition responses after analysis, within 5 seconds after the service management equipment sends the 15 simulation service acquisition requests, the equipment A sends the 15 simulation service acquisition responses to the service management equipment, and then the single-channel unit time analysis capability index of the equipment A is 15/5/3=1 second.

In practical applications, the actions in the first case and the actions in the second case may be executed separately or in combination according to the content of the capability information that needs to be acquired actually, which is not limited in this embodiment of the present invention.

In practical applications, due to aging of the service providing device during use and other reasons, the single-channel response may change over time, and therefore, the service management device may periodically recalculate the single-channel time analysis capability index of each type of service provided by each available service providing device, so as to ensure the accuracy of the single-channel time analysis capability index obtained by the service management device. The period of the recalculation may be 3 days or 30 days, and the period may be determined according to the provision situation of the specific service in the specific service providing device, which is not limited in the embodiment of the present invention.

Step 305, after receiving the service acquisition request, the service management device determines a target type of a service requested to be provided by the service acquisition request.

In the embodiment of the present invention, the target type is a service type requested to be provided by the service acquisition request, and may be, for example, an image target tracking type, an image modeling type, or an image attribute extraction type.

Optionally, the service acquisition request may carry an identifier of the target type, and the service management device may determine the target type of the service required by the data to be analyzed based on the identifier.

For example, the service management device receives a service acquisition request sent by the application device, where the service acquisition request carries an identifier 00, and the service management device generally queries a pre-configured identifier-type correspondence relationship, and determines that a target type corresponding to the identifier 00 is an image modeling type.

Optionally, the service acquisition request usually also carries data to be analyzed. Therefore, the number of transmitted requests can be reduced, and the network overhead is saved.

Step 306, the service management device obtains a load pressure value of the target service in each target service providing device.

The target service providing device is used for providing a target service, and the target service is a target type service. The service management device may perform screening in the available service providing device according to the determined target type, determine, when a device for providing the target service exists in the available service providing device, the device as the target service providing device, reply an application device service failure response when no service providing device for providing the target service exists in the available service providing device, where the service failure response may carry indication information, where the indication information is used to indicate that the service providing device providing the target service is not found.

For example, assume that based on the target type: the image modeling type is screened by the service management device in the available service providing device based on the target type, and the service providing device capable of providing the image modeling type service is obtained by the following steps: device B, device C, and device D, then the target service device is determined to be: device B, device C, and device D.

In the embodiment of the present invention, for any service providing device, the load pressure value may be reflected based on a data volume currently processed by the service providing device, where the currently processed data volume is positively correlated with a number of service acquisition requests currently processed by the service providing device, that is, the greater the number of service acquisition requests currently processed by the service providing device, the greater the currently processed data volume is, the greater the load pressure value of the service providing device is.

In the embodiment of the present invention, the service management device may update the load pressure value in real time according to the receiving and sending conditions of the service acquisition request, and after receiving the service acquisition request sent by the application device, the service management device may obtain the current load pressure value of the target service in each target service providing device.

For example, the service management device may set a load pressure value P =0 of the target service in each target service providing device at an initialization time (the initialization time may be when the service management device is powered on, or when the staff triggers an initialization instruction), and then perform an update process of the load pressure value at least once, where, assuming that the first target service device is any one of all the obtained target service providing devices, the update process includes, for the first target service device:

the method comprises the steps that after a service management device sends a specified service acquisition request to a first target service providing device each time, a load pressure value P is updated, and the updated load pressure value P = P +1; the specified service acquisition request carries target type data to be analyzed. The service management device updates the load pressure value P after receiving a service acquisition response to the specified service acquisition request returned by the first target service providing device each time, so that the updated load pressure value P = P-1.

For example, it is assumed that the first target service providing apparatus is any one of apparatus B, apparatus C, and apparatus D. Before the service management device acquires the load pressure value of the target service in each target service providing device, the service management device sets the load pressure value P respectively _B 、P _C And P _D Are all 0, wherein, P _B 、P _C And P _D The load pressure value of the target service in the device B, the load pressure value of the target service in the device C, and the load pressure value of the target service in the device D, respectively.

It is assumed that the first target service providing apparatus is apparatus B. The service management device updates the load pressure value P after sending a specified service acquisition request to the device B for the first time _B So that the updated load pressure value P _B ＝P _B +1=0+1=1; at one kind of falseIn the setting, after the service management device sends the specified service acquisition request to the device B for the first time, the specified service acquisition request is not sent again, and after the service management device receives the service acquisition response returned by the device B for the first time, the load pressure value P is updated _B So that the updated load pressure value P _B ＝P _B -1=0; in another assumption, the service management device updates the load pressure value P after sending the specified service acquisition request to the device B for the second time after sending the specified service acquisition request to the device B for the first time and before not receiving the service acquisition response yet _B So that the updated load pressure value P _B ＝P _B +1＝1+1＝2。

Step 307, the service management device performs service distribution of the available service providing devices based on the capability information of the target service in each target service providing device and the load pressure value of the target service in each target service providing device.

The service management device dynamically distributes the services of the available service providing devices based on the capability information of the target service in each target service providing device and the load pressure value of the target service in each target service providing device, so that the dynamic adjustment of the service distribution strategy is realized, and the load balance of each target service providing device can be ensured.

Optionally, step 307 may include:

step A, calculating an idle analysis index of the target service in each target service providing device based on the capability information of the target service in each target service providing device and the load pressure value of the target service in each target service providing device.

The idle analysis index is used for reflecting the idle degree of the corresponding service providing equipment for providing the target service. The idle analysis index is positively correlated with the idle degree, that is, the larger the idle analysis index is, the higher the idle degree of the resource used by the service providing device to provide the target type service is, and more resources are available to provide the target service, and the smaller the idle analysis index is, the lower the idle degree of the resource used by the service providing device to provide the target service is.

For example, the idle analysis index is calculated by:

calculating an idle analysis index L of a target service in a first target service providing device based on an idle analysis index calculation formula, wherein the idle analysis index calculation formula of the target service for the first target service providing device is assumed to be any one of all target service providing devices, and the first target service providing device is assumed to be any one of all target service providing devices:

L＝M-P×X；

wherein M is a service index of the target service in the first target service providing device, P is a load pressure value of the target service in the first target service providing device, and X is a load pressure weight of the target service in the first target service providing device.

For example, assuming that the service index of the target service in the first target service providing device is 10, i.e., M =10, the load pressure value of the target service in the first target service providing device is 3, i.e., P =3, and the load pressure weight of the target service in the first target service providing device is 0.5, i.e., X =0.5, the idle analysis index L =10-3 × 0.5=8.5.

The service index of the target service in each target service providing device is used for reflecting the service capability of the target service, and is obtained according to the capability information of the target service of each target service providing device.

In an alternative implementation, after the target service is determined, the service index of the target service in each target service providing device may be calculated based on a service index calculation formula.

In another alternative implementation, after the capability information of each type of service provided by each available service providing device is obtained through the foregoing step 304, the service index of each service provided by each available service providing device may be calculated based on a service index calculation formula, and in step 307, the service index of the target service in each target service providing device, which is calculated in advance, is directly obtained. Therefore, the idle analysis index can be calculated quickly, the calculation time delay is reduced, and the effectiveness of subsequent service distribution is ensured.

For example, for any type of service provided by any available service providing device, the service index of the service providing device is a weighted value of the information of the at least one service capability parameter of the any service. Then, for the ith type of service of any service providing device, the service index calculation formula is:

wherein M is _i Service index, K, for the ith type of service _ij Providing information of a jth service capability parameter of an ith type of service of the device for the any service. A. The _ij J is more than or equal to 1 and less than or equal to J, I is more than or equal to 1 and less than or equal to I, and I is the number of types of services which can be provided in any service providing equipment.

For example, when a service index is performed for each type of service provided by the ith available service providing apparatus, it is assumed that the capability information of each type of service provided by the ith available service providing apparatus includes: analyzing information of channel number, algorithm library capability index and single channel unit time analysis capability index, and calculating service index M of the ith type of service according to the information of the three service capability parameters _i Then the service index M _i Satisfies the following conditions:

M _i ＝K _i1 ×A _i1 +K _i2 ×A _i2 +K _i3 ×A _i3 ；

wherein, K _i1 For analyzing the number of channels, K _i2 Is an algorithm library capability index, K _i3 Is a single-channel unit time analysis capability index. A. The _i1 、A _i2 And A _i3 And the weights are respectively corresponding to the analysis channel number, the algorithm library capability index and the single-channel unit time analysis capability index.

Since the service index of each type of service of each available service providing device is calculated according to the weight of at least one service capability parameter of the service providing device, the service index can effectively characterize the service capability of the type of service.

Further, the idle analysis index is determined according to the service index, the load pressure value and the load pressure weight of the target service in the target service providing device, and since the idle degree of each target service providing device is not only related to the currently processed data amount but also related to the self service capability of each target service, in the embodiment of the present invention, the idle analysis index is associated with the self service capability factor of each target service and also associated with the load pressure factor of each target service, the idle analysis index effectively embodies the idle degree of each target service.

And step B, when the target service providing equipment with the idle analysis index larger than the designated index threshold exists, sending a service acquisition request to the target service providing equipment with the maximum idle analysis index so as to provide the target service by the target service providing equipment with the maximum idle analysis index.

Optionally, the service management device is provided with a specified index threshold, and the specified index threshold may be dynamically determined based on the data volume of the data to be analyzed, or may be a preset threshold.

When the target service providing equipment with the idle analysis index of the target service larger than the designated index threshold value exists, the service management equipment compares the idle analysis indexes of the target services in all the target service providing equipment, and sends a service acquisition request to the target service providing equipment with the maximum idle analysis index so as to provide the target service by the target service providing equipment with the maximum idle analysis index.

For example, assume that the target service providing device is: device B and device C, idle analysis index L for target service in device B and device C _B And L _C And L is _B >L _C While assuming that the specified indication threshold is 2.

Idle analysis index L of target service in device B and device C _B And L _C When at least one is present, greater than 2, e.g.L _B And L _C Are both greater than 2 and according to L _B >L _C The service management device sends a service acquisition request to the device B to provide the target service by the device B with the largest idle analysis index.

And step C, when the target service providing equipment with the idle analysis index larger than the designated index threshold does not exist, the service management equipment processes the service acquisition request sent by the application equipment.

And when the idle analysis index of the target service in each target service providing device is smaller than the designated index threshold value, processing the service acquisition request sent by the application device, thereby ensuring the stability of the target service provided by each target service providing device. The processing mode can be various, and the embodiment of the present invention is described by taking the following three modes as examples.

In the first way, when there is no target service providing device having an idle analysis index greater than a specified index threshold, the service management device replies a service failure response to the application device.

And when the idle analysis index of the target service in each target service providing device is less than the designated index threshold value, the service management device replies a service failure response to the application device. For example, the service failure response may be service failure information carrying a reason of the service failure, for example, the service failure response includes information that the service providing device is busy, the application device may present the service failure information in the form of text or voice on the input/output interface when receiving the service failure response, for example, the input/output interface is a display screen, the application device pops up a window in the display interface of the display screen, and the service failure information is presented in the form of text in the window, for example, the text is "the service providing device is busy, please try again later |! ".

In a second mode, when there is no target service providing device with an idle analysis index greater than a specified index threshold, the service management device establishes a waiting mechanism until there is a target service providing device with an idle analysis index greater than a specified index threshold, and sends the service acquisition request to the target service providing device with the maximum idle analysis index.

When the idle analysis index of the target service in each target service providing device is smaller than the designated index threshold, the service management device establishes a waiting mechanism to avoid affecting the target service being executed, and the service management device needs to wait for the increase of the idle analysis index of the target service in the first target service providing device, that is, for the reduction of the load pressure value of the target service in the first target service providing device, until the idle analysis index of the target service in the first target service providing device is larger than the designated index threshold, send a service acquisition request to the first target service providing device, so that the target service providing device with the largest idle analysis index provides the target service.

In a third mode, when the target service providing device with the idle analysis index larger than the designated index threshold value does not exist, the service management device establishes a waiting mechanism until the waiting time is out, and replies a service failure response to the application device.

When the idle analysis index of the target service in each target service providing device is smaller than the specified index threshold, the service management device establishes a waiting mechanism until the waiting time is out, and replies a service failure response to the application device, where the service failure response may be the same as the service failure response in the first manner, and details thereof are not repeated in the embodiment of the present invention.

When the target service providing equipment with the idle analysis index larger than the designated index threshold value does not exist, the current communication concurrent pressure exceeds the service capacity range.

It should be noted that the service management device may further send the capability information and the access address of the target service in each target service providing device to the application device, the application device presents the capability information and the access address to the user of the device, the user selects the target service that the user wants to access, the application device directly sends the service acquisition request carrying the data to be analyzed to the access address of the selected target service, and the corresponding target service device provides the target service.

Step 308, the service management device detects whether each available service providing device reaches the logout condition through the heartbeat mechanism, and when any service providing device reaches the logout condition, the service management device logs out any service providing device.

For each service providing apparatus, the logout condition may be that the number of times of heartbeat communication disconnection with the service managing apparatus is greater than a specified disconnection number threshold.

Illustratively, for each service providing device, the service management device configures an anomaly indicator W =0 after the service providing device is registered, and in a subsequent process, a heartbeat detection process is executed at a specified time interval, where the heartbeat detection process includes:

sending a heartbeat signal to the service providing equipment once, if a heartbeat response returned by the service providing equipment for the heartbeat signal is received, determining that the current heartbeat communication connection is normal, if a heartbeat response returned by the service providing equipment for the heartbeat signal is not received, determining that the current heartbeat communication connection is abnormal (namely the current heartbeat communication connection is disconnected), and updating an abnormal indicator, so that the updated abnormal indicator W = W +1.

After the heartbeat detection process is executed every time, the current abnormal indicator W can be obtained, whether the current abnormal indicator W is larger than a threshold value of the specified disconnection times or not is judged, and when the current abnormal indicator W is larger than the threshold value of the specified disconnection times, the service providing equipment is determined to meet the logout condition; and when the current abnormal indicator W is not greater than the threshold value of the specified disconnection times, determining that the service providing equipment does not meet the logout condition, and executing the heartbeat detection process again until the current abnormal indicator W is greater than the threshold value of the specified disconnection times.

It should be noted that, for all available service providing devices, the service management device may sequentially execute the heartbeat detection process once for all the available service providing devices at intervals of a specified duration; alternatively, the service management device may specify a duration at intervals, and execute the heartbeat detection process once for each available service providing device, which is not described in detail in this embodiment of the present invention.

Step 309, the service management device allocates a dynamic security code for each application platform registered on the service management device, where the dynamic security code is used for generating an encryption token based on an agreed encryption algorithm, the dynamic security code, and a timestamp when the application device under the application platform communicates with the service management device.

The method comprises the steps that a service management device distributes dynamic security codes to application accounts of each registered application platform (the registered application accounts are legal accounts), the application devices under each application platform initiate service obtaining requests to the service management device, the service obtaining requests comprise encrypted tokens, the encrypted tokens are used for authority verification of the application accounts of the application platforms by the service management device, after receiving the service obtaining requests, the service management device can conduct authority verification on the application accounts, whether the authority verification passes or not is judged, if the authority verification passes, the service management device conducts service obtaining request distribution to a service providing device, and if the authority verification does not pass, the service management device returns failed responses to the application devices under the application platforms. For example, the fail response may carry fail information (also referred to as error information) that may indicate a reason for the failed permission check.

Optionally, after receiving the failure response, the application device may present the failure information in the input/output interface in a text or voice form, for example, the input/output interface is a display screen, the application device pops up a window in the display interface of the display screen, and the failure information is presented in text in the window, for example, the text content is "you are not a registered application user", or "please register an application account", or "the service acquisition request is overtime".

Assuming that the first application device is an application device under a first application platform, the first application account is an application account registered by the first application platform, the service management device decrypts an encrypted token included in a service acquisition request sent by the first application device to obtain a decrypted token, wherein the decrypted token includes a dynamic security code and a timestamp, and verifies the content of the decrypted token, thereby performing permission verification on the first application account. In the embodiment of the present invention, the encrypted token is generated based on an agreed encryption algorithm, a dynamic security code, and a timestamp, where the timestamp is time information of a service acquisition request initiated by an application device. Accordingly, the process of verifying the content of the decrypted token, i.e. the process of verifying the rights, may include the following two steps:

the first step, whether the first application account is a registered application account is checked based on the dynamic security code.

The service management device compares the dynamic security code in the decryption token with the dynamic security code sent by the service management device to the first application platform, if the two are the same, the first application account is a registered application account, namely a legal application account, and if the two are different, the service management device judges that the permission verification is not passed, and the first application account is an illegal application account.

And a second step of checking whether the service acquisition request sent by the first application equipment is valid in time or not based on the timestamp.

The service management device is provided with an effective time threshold value used for judging whether the service acquisition request sent by each application device is effective in time. The service management device may determine a time difference between a time corresponding to the timestamp carried in the decryption token and a time of the service acquisition request received by the service management device, determine whether the time difference is greater than an effective time threshold, and if the time difference is greater than the effective time threshold, the service management device determines that the service acquisition request is invalid in time and determines that the permission check fails; if the time difference is smaller than the valid time threshold, the service management device determines that the service acquisition request is valid in time.

It should be noted that, in the embodiment of the present invention, the execution order of the two steps is not limited, that is, the service management device may first check the valid application account, and then check the validity of the service acquisition request in time; or, the service management device may check the validity of the service acquisition request in time, and then check the valid application account; of course, the above two steps may also be performed in parallel.

Because the encrypted token is generated based on the dynamic security code and the timestamp, the encrypted token can not only ensure the validity of the application platform initiating the service acquisition request, but also verify the validity of the service acquisition request in time through the timestamp in the encrypted token.

In practical application, the service management device performs the permission verification on the first application account, may simultaneously verify the two steps, may only verify any one of the steps, and may change the contents of the encrypted token according to the situation, thereby changing the contents of the permission verification. The content of the right check may be changed according to specific situations, which is not limited in the embodiment of the present invention.

It should be noted that, the foregoing step 307 is exemplified by the implementation environment of fig. 1 or fig. 3, and it is assumed that the service management device performs service distribution, as described above, when the service providing system is the service providing system shown in fig. 2, the foregoing service distribution action may also be performed by the service distribution device, and then the foregoing step 307 may be replaced by performing, by the service distribution device, service distribution of the available service providing devices based on the capability information of the target service in each target service providing device and the load pressure value of the target service in each target service providing device. Still alternatively, step 307 may be executed by the service management device and the service distribution device cooperatively, for example, the idle analysis index in the foregoing step a is executed by the service management device, and the remaining steps B to C are executed by the service distribution device.
