Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The embodiment of the invention receives the service request sent by each terminal device through the service distribution middleware and forwards the service request to the corresponding processing control middleware, determining the service type contained in the service request through the processing control middleware, configuring corresponding task information for different service types, and sends each task information to the corresponding service processing node for response, encapsulates the processing results fed back by all the service processing nodes to obtain the response result about the service request, realizes the purpose of parallel processing of multiple types of services, solves the response technology of the existing service request, since different service requests are handled by the same server, when a service request relates to a different service type, easily causing a conflict of processing logics and extending the service response time length, thereby reducing the efficiency of service response.
In the embodiment of the invention, the execution subject of the flow is a response system of the service request. The response to the service request includes service distribution middleware, process control middleware, and at least one service processing node. The service distribution middleware and the processing control middleware may be a server, and the service processing node may be a server or a server cluster including a plurality of servers. Fig. 1 shows a flowchart of an implementation of a method for responding to a service request according to a first embodiment of the present invention, which is detailed as follows:
in S101, a service request transmission is transmitted.
In this embodiment, the terminal device may send the service request to the response system of the service request through a client installed locally or a web page associated with the response system of the access service request. The service request carries a service type or a service identifier of a request, and optionally, the service request may further include a service requester, that is, the device identifier of the terminal device. The response system of the service request can converge all the service requests received from the terminal side to the service distribution middleware and forward the service requests through the service distribution middleware.
For example, the terminal device sending the service request may be an intelligent robot, and during an automation process of the intelligent robot, the intelligent robot may package the acquired environment information, generate a target identification request, that is, the service request is a service request for identifying a target object, and send the service request including the environment information to the service distribution middleware. The intelligent robot can perform cloud processing on the acquired information through a response system with the service request, so that the data processing capacity can be improved.
For example, the terminal device sending the service request may be a distributed camera device, and the distributed camera device may collect video data of the current environment, package the video data into a face recognition request, that is, the service request is a service request for face recognition, and send the service request including the video data to the service distribution middleware. The distributed camera device can perform cloud processing on the collected video data through a response system with the service request, so that the purpose of face recognition is achieved, the accuracy of face recognition can be improved by performing face recognition through a cloud end, compared with the technology of completing face recognition through a local mode, the recognition efficiency can be greatly improved, the requirements of a processing module of the distributed camera device are reduced, and the manufacturing cost of the distributed video device is reduced.
For example, the terminal device sending the service request may be a user terminal, for example, a smart device such as a smart phone, a tablet computer, or a smart watch used by a user, and encapsulates collected information, for example, voice data (for performing voice recognition) or image data (for performing face recognition, text recognition, or object recognition) into the service request, and processes the data recognition through a response system of the service request, so that the smart recognition range of the user terminal can be enhanced, and the usability of the terminal device can be expanded.
In this embodiment, the service distribution middleware serves as a sink node of the service request, sends the service request initiated by all the terminal devices to the service distribution middleware, and forwards the service request to the corresponding processing control middleware through the service distribution middleware.
In this embodiment, after the terminal device sends a service request to the service distribution middleware, the service distribution middleware may configure a corresponding session identifier, that is, a SessionID, for the service request; when the terminal equipment sends a service request to a response system of the service request for the first time through a built-in client, the system creates a Session for the client, configures a corresponding Session ID for each service request through a preset Session identifier generation algorithm, and the service distribution middleware establishes a corresponding relationship between a client Session represented by the Session ID and the service request of the Session, namely the request of the Session contains the Session ID and the service request, and stores the corresponding relationship in a database, thereby facilitating the subsequent query operation.
Optionally, in this embodiment, before forwarding the service request to the process control middleware, the service distribution middleware may filter the abnormal service request through the data filtering unit, that is, deploy the data filtering unit between the communication links between the service distribution middleware and the process control middleware. After receiving a service request sent by a user terminal, the data filtering unit determines whether the service request contains a preset key parameter item, where the key parameter item includes, but is not limited to, a service type, a terminal identifier of the user terminal, a network address, and other one or more combinations. If the data filtering unit detects that the service request does not contain any key parameter item, the data filtering unit identifies the service request as an abnormal request and filters the abnormal request, so that data is cleaned, a large number of invalid requests are prevented from entering a response system of the service request, the safety of the system is improved, response operation of the invalid requests is reduced, and resource waste is avoided.
In S102, a service type corresponding to the service request is identified, and task information about the service request is configured for each service type.
In this embodiment, after receiving the service request sent by the service distribution middleware, the processing control middleware identifies a service type corresponding to the service request. The service type may include one or a combination of two or more of the following: the target recognition type, the face recognition type, the voice recognition type, the biological sign recognition type, the character recognition and other services. The processing control middleware may determine a corresponding service type according to the request content of the service request, and may query the corresponding service type based on the service identifier if the service request carries the service identifier.
It should be noted that, part of the service request may be completed together through a plurality of service logics, for example, the intelligent robot sends environment video data, needs to identify a target type in the environment, needs to perform face recognition on an object of a "person" type after identifying the target type, and then the service request includes two service types, namely, target type recognition and face recognition. Therefore, the processing control middleware needs to determine the service type corresponding to the service request, and the service type may be one or a combination of multiple types.
Optionally, in this embodiment, the processing control middleware may be configured with a service request index table, where the service request index table includes service types corresponding to the service requests. The terminal device may determine the service type associated with each received service request by querying the service request index table. For example, the processing control middleware may determine, by a bit value of a preset byte in the service identifier, an entry corresponding to the service request in the service request index table, and query a service type included in the entry.
In this embodiment, because different service types are processed by different service processing nodes, the service processing middleware needs to split the service request, divide the service request into different task information, where each task information corresponds to one service type, and define the content that the service type needs to complete.
In S103, a service processing node associated with the service type is queried, and the task information is sent to the service processing node, so that a task result of the task information is output by the service processing node.
In this embodiment, the processing control middleware may configure a correspondence table between service types and service processing nodes, where each service processing node may correspond to one service type. The service response middleware may query the correspondence table, determine a service processing node corresponding to a service type for responding to the received service request, and send task information corresponding to the service type to the service processing node associated with the service type for processing.
Optionally, in this embodiment, the process control middleware may configure a state list related to the operating state of the service processing node. The state list includes the service type and the operation state associated with each service processing node. When a service response request of any service type does not exist in a response system of the service request, the service response middleware can adjust the running state of the first service processing node associated with the service type to a closed state and update a state list; if the running state of the service processing node corresponding to the service type received by the response system of the service request is detected to be the closed state, the service processing node corresponding to the service type can be started, and the state list is updated. The processing control middleware can determine the service types which can be responded in the current service response system and the currently started service types according to the state list, and open and close the corresponding service processing nodes based on the service types contained in the received service request, so that the resource consumption of the service response system can be reduced.
In this embodiment, the service processing node receives the task information forwarded by the processing control middleware, responds to the issued task information, and generates a corresponding task result. Alternatively, the service processing node may add the task information into the response queue and sequentially respond based on the addition order of the respective task information.
Optionally, in this embodiment, the processing control middleware may set a maximum response time length. After the processing control middleware sends the task information, the processing control middleware starts a response timer and detects whether the count value of the response timer is greater than the maximum response time length. If the counting value of the response timer is detected to be larger than the maximum response time and the task result fed back by the service processing node is not received, the service processing node without the task result can be identified as an abnormal node, and abnormal processing information is generated so that maintenance personnel can process the abnormal node.
In S104, a service response result of the service request is generated according to the task result fed back by the service processing node, and the service response result is sent.
In this embodiment, the processing control middleware receives task results fed back from each service processing node, packages and merges all task results, generates a service response result corresponding to the service request, extracts a communication address corresponding to the terminal device that sends the service request from the service request, and sends the service response result to the terminal device based on the communication address, thereby completing the service response flow.
Optionally, the processing control middleware may feed back the generated service response result to the service distribution middleware, and since the service distribution middleware may maintain a communication link and/or session with the terminal device, the service response result may be sent to the service distribution middleware and sent to the terminal device through the service distribution middleware.
As can be seen from the above, in the service request response method provided in the embodiment of the present invention, the service allocation middleware receives the service request sent by each terminal device, and forwards the service request to the corresponding processing control middleware, the processing control middleware determines the service type included in the service request, configures corresponding task information for different service types, sends each task information to the corresponding service processing node for response, and encapsulates the processing results fed back by all the service processing nodes to obtain the response result related to the service request, thereby achieving the purpose of processing multiple types of services in parallel. Compared with the prior art for responding service requests, the method and the system have the advantages that the corresponding service processing nodes are configured for different service types, the service types related to the service requests are subjected to task division through the processing control middleware to obtain a plurality of task information, and the task information is sent to the corresponding service processing nodes to be processed according to the service types, so that the independence of processing logics of the service requests of different types can be guaranteed, the parallel processing of multiple types of tasks can be realized, the coupling degree among different service types is reduced, the service response efficiency is improved, and the service response duration is reduced.
Fig. 2 shows a flowchart of a specific implementation of S103 of a method for responding to a service request according to a second embodiment of the present invention. Referring to fig. 2, with respect to the embodiment described in fig. 1, a method S103 for responding to a service request provided in this embodiment includes: s1031 to S1033 are specifically described as follows:
further, the service processing node comprises a plurality of cluster servers; the querying the service processing node associated with the service type and sending the task information to the service processing node includes:
in S1031, the operation parameters fed back by each cluster server in the service processing node are obtained.
In this embodiment, each service processing node may include a plurality of cluster servers, where the plurality of cluster servers together form the service processing node, and are configured to process all tasks of the service type corresponding to the service processing node. The service processing node may be configured with an available device list, where the available device list records all cluster servers included in the service processing node and is marked with an operating parameter corresponding to each cluster server. Before sending the task information, the process control middleware may obtain the operating parameters of each cluster server by reading the available device list.
In this embodiment, the cluster server may actively feed back the operation parameters, for example, a response system of the service request may be configured with a feedback period, and if the cluster server detects that the current time reaches the preset feedback period, the cluster server may obtain the local operation parameters and upload the operation parameters; the response system of the service request may also be provided with a plurality of operation thresholds, and if the cluster server detects that the operation threshold is exceeded or fallen below at a certain time, the cluster server may feed back a notification message to the response system of the service request to notify the response system of the service request that the operation parameter of the cluster server reaches a certain parameter range.
Optionally, the cluster server may passively send the operation parameter, and after receiving the service request, the processing control middleware may send a broadcast message to the service processing node corresponding to the service type to notify all cluster servers connected to the service processing node to feed back the operation parameter.
It should be noted that the operation parameter is a parameter indicating the operation condition of the current environment of the cluster server, and the operation parameter includes, but is not limited to: a combination of one or more of a load value, network bandwidth, network rate, available hardware resource value, data processing rate, and/or available thread count.
In S1032, the response priority of each cluster server is calculated by a preset load balancing algorithm.
In this embodiment, after acquiring the operating parameters of each cluster server, the processing control middleware may respectively calculate the response priority of each cluster server, where if the response priority of a cluster server is higher, the data processing capability of the cluster server is higher, and conversely, if the corresponding response priority of a cluster server is lower, the data processing capability of the cluster server is lower. Therefore, it is possible to determine to which cluster server within the service processing node the task information is specifically allocated to respond by the size of the response priority.
Optionally, in this embodiment, the way for the processing control middleware to calculate the response priority may be: and the processing control middleware configures corresponding reference values for different operation parameters, respectively calculates the ratio between the actually acquired operation parameters and the corresponding reference values, and performs weighted superposition according to the weights corresponding to the operation parameters, thereby calculating the response priority of the cluster server.
Wherein Priority is the response Priority of the cluster server, FactRuniThe ith operating parameter of the cluster server; StandardRuniIs the ith reference value ξiAnd n is the total number of the operation parameters.
Optionally, in this embodiment, the way for the processing control middleware to calculate the response priority may be: the processing control middleware can perform normalization operation on each operation parameter, and superimposes the normalized operation parameters according to the preset weight of each operation parameter, so as to calculate the response priority of the cluster server, wherein the specific formula is as follows:
wherein Priority is the response Priority of the jth cluster server, FactRunjiξ as the ith operating parameter of the jth cluster serveriThe weight value corresponding to the ith operating parameter is obtained, and n is the total number of the operating parameters; and m is the total number of the cluster servers.
In S1033, the cluster server with the highest response priority is selected as a target server, and the task information is sent to the target server.
In this embodiment, after the processing control middleware calculates the response priority of each cluster server, the cluster servers may be sorted according to the priority value, and the cluster server corresponding to the largest value of the response priority is selected as the target server, and the task information corresponding to the service request is processed by the target server.
In the embodiment of the invention, the response priority of each cluster server in the service processing node is obtained, and the cluster server with the highest priority is selected as the target server, so that the purpose of load balancing can be realized, and the data processing capacity of the response system of the service request and the stability of the system are improved.
Fig. 3 shows a flowchart of a specific implementation of a method S1031 for responding to a service request according to a third embodiment of the present invention. Referring to fig. 3, with respect to the embodiment described in fig. 2, a method S1031 for responding to a service request provided by this embodiment includes: s301 to S303 are specifically detailed as follows:
further, the response system of the service request also comprises a node registration server; the obtaining of the operation parameters fed back by each cluster server in the service processing node includes:
in S301, if it is detected that a preset feedback condition is satisfied, the operation parameter is sent to the node registration server.
In this embodiment, the cluster server may be configured with a feedback condition, where the feedback condition may be a time trigger condition, in this case, the cluster server may be provided with a feedback period or a feedback time node, and if it is detected that the current time reaches a feedback time node or a feedback period that meets a preset condition, the cluster server recognizes that the current time meets the feedback condition, and performs the operation of S301. The feedback condition may also be an event trigger condition, in which case, when a feedback instruction fed back by the node registration server is received, it is identified that a preset event trigger condition is satisfied, or an instantaneous parameter change ratio is set, and if it is detected that a change rate of an operation parameter of the cluster server is greater than the instantaneous parameter change ratio within a certain time period, it is identified that the feedback condition is satisfied, and the operation parameter is sent to the node registration server.
In this embodiment, the node registration server may be configured to manage the operating status of each cluster server. When the cluster server is started, a registration instruction needs to be sent to the node registration server, and the node registration server adds the cluster server into the monitoring list and obtains the operating parameters of each cluster server in the monitoring list.
In S302, the operating parameters of each cluster server are recorded by the node registration server.
In this embodiment, the node registration server may store the operation parameters fed back by each cluster server, and establish a corresponding relationship between the cluster server and the operation parameters.
Optionally, the node registration server may configure a corresponding effective time for each operation parameter, and the lengths of the effective times corresponding to different operation parameters may be different or the same. After receiving the operation parameters fed back by the cluster server, the node registration server starts a timer corresponding to the operation parameters, if the count value of the timer is detected to be greater than the effective duration corresponding to the operation parameters and the operation parameters returned by the cluster server are not received, the node registration server identifies that the currently recorded operation parameters are invalid, and sends a parameter feedback instruction to the cluster server to reacquire the operation parameters of the cluster server.
In S303, the node registration server receives the query instruction sent by the processing control middleware, and sends the operating parameter of each cluster server in the service processing node corresponding to the node identifier to the processing control middleware according to the node identifier included in the query instruction.
In this embodiment, the node registration server may be configured to store the operating parameters of the cluster servers in all the service processing nodes. Before receiving the service request and sending the task information, the processing control middleware may send a query instruction to the node registration server, where the query instruction carries a node identifier to be queried, and the node identifier is used to define a service processing node to be invoked for responding to the service request.
In this embodiment, the node registration server may analyze the query instruction, determine the target service processing node through the node identifier, determine each cluster server associated with the service processing node, query the operating parameters corresponding to each cluster server, encapsulate all the operating parameters, and send the encapsulated operating parameters to the processing control middleware.
In the embodiment of the invention, the running state of each cluster server is managed through the node registration server, and the processing control middleware can obtain the running parameters of all the cluster servers through the node registration server, so that the obtaining efficiency of the running parameters can be improved.
Fig. 4 is a flowchart illustrating a specific implementation of a method for responding to a service request according to a fourth embodiment of the present invention. Referring to fig. 4, in relation to the embodiment described in fig. 1, the method for responding to a service request provided in this embodiment further includes: s401 to S403 are specifically described as follows:
further, the response system of the service request further comprises deployment middleware; the service processing node comprises a plurality of cluster servers; the response method of the service request further comprises the following steps:
in S401, the load value of each cluster server is obtained through the deployment middleware.
In this embodiment, the deployment middleware may be configured to manage the operating states of the cluster servers, and if it is detected that the load condition of the current network is low, a certain number of cluster servers may be closed, so as to reduce energy consumption of the system; if the load condition of the current network is detected to be higher, a certain number of cluster servers can be started to improve the data processing capacity of the system and dynamically adjust the response capacity of the service request of the response system of the service request.
In this embodiment, the deployment middleware may obtain the load value of the cluster server in a preset monitoring period, and obtain the overall load condition of the response system of the entire service request.
In S402, if it is detected that the load value of each cluster server in any service processing node is greater than a preset first load threshold, a standby server is started, and the standby server is added to the available device list of the service request node.
In this embodiment, when the deployment middleware detects that the load value of each cluster server is greater than the preset first load threshold, it indicates that the load of the entire service processing node is in a higher state, and possibly some cluster servers are in a full load or overload condition, and it is necessary to perform capacity expansion operation on the service processing node, select one of the standby servers as a capacity expansion server, set the operating state of the capacity expansion server as an open state, set the capacity expansion server as an available device list of the service request node, and then when subsequently receiving task information of the service type, send the task information to the expanded standby server for processing.
In S403, if it is detected that the load value of each cluster server in any of the service processing nodes is smaller than a preset second load threshold, at least one cluster server is selected from the service processing nodes as a redundant server, and the redundant server is closed.
In this embodiment, when the deployment middleware detects that the load value of each cluster server is smaller than the preset second load threshold, it indicates that the load of the entire service processing node is in a lower state, and then the tasks of the service type corresponding to the service processing node are fewer, and at this time, the corresponding number of servers may be closed, so that the corresponding number of cluster servers is selected as the redundant server, and the redundant server is closed, thereby reducing the resource consumption of the response system.
In the embodiment of the invention, the deployment middleware is added into the response system of the service request, and the deployment middleware is used for controlling the on-off state of the cluster server, so that the processing capacity of each service processing node can be dynamically adjusted, and the resource utilization rate is improved.
Fig. 5 is a flowchart illustrating a specific implementation of the method S103 for responding to a service request according to a fifth embodiment of the present invention. Referring to fig. 5, with respect to any of the embodiments shown in fig. 1 to 4, a method S103 for responding to a service request provided in this embodiment includes: S501-S502 are detailed as follows:
further, the querying, by the processing control middleware, a service processing node associated with the service type, and sending the task information to the service processing node, so as to output a task result of the task information through the service processing node, including:
in S501, a response procedure associated with the service request is obtained, and a processing order corresponding to each piece of task information is determined based on the response procedure.
In this embodiment, after obtaining the service request, the processing control middleware may query a response procedure associated with the service identifier according to the service identifier corresponding to the service request. The service identification may be associated with session information sent by the service request. The terminal device may send the service request to a response system of the service request through different clients, and when the different clients establish a communication connection with the response system, the session information used is different, for example, the service request sent through different channels, that is, the clients, may be marked by information such as a session number. Based on this, the response system of the service request can determine the client corresponding to the service request by analyzing the session information of the service request, and when responding to the service request placed by different clients, the corresponding response flows are different, so that the response flow of the service request can be determined by analyzing the session information.
In this embodiment, the response flow is specifically used to define the tasks that need to be executed when responding to the service request and the processing order among the tasks, and based on this, the processing control middleware may determine a plurality of task nodes by analyzing the response flow, configure corresponding task information for different task nodes, and determine the processing order of each task information based on the position of each task node in the response flow.
In S502, based on the processing order, the service processing nodes corresponding to the task information are sequentially assigned.
In this embodiment, the processing control middleware may send the task information to the corresponding service processing node according to the determined response order, and send the task information of the next response order to the service processing node of the next processing order after receiving the processing result fed back by the service processing node. Optionally, if an iterative relationship exists between the multiple service processing nodes, that is, the service processing node in the next processing order needs the processing result in the previous processing order, the processing control middleware may add the processing result fed back by the previous processing order into the task information in the next processing order, and send the added task information to the service processing node corresponding to the next processing order.
For example, for the face recognition process, it is necessary to first recognize the object type of each object in the image information, and perform face recognition from the object whose object type is "person". Therefore, the processing control middleware can send the task information identified by the object type to the first service processing node and receive the object type list fed back by the first service processing node; and adding the object type list into the task information, and delivering the task information to a second service processing node for processing face recognition for subsequent processing.
In the embodiment of the invention, the processing sequence of each task information is determined by obtaining the response flow of the service request, and the accuracy of the service request processing logic is ensured.

further, the sending the service request includes:
in S1011, a topic type associated with the service request is identified.
In this embodiment, each service request corresponds to a Topic type, i.e., Topic. The service distribution middleware and the processing control middleware can determine the processing control middleware corresponding to different topic types by establishing a publish-subscribe relationship. Based on this, after receiving the service request, the service distribution middleware needs to determine the topic type associated with the service request.
Optionally, the topic type may be determined according to a session identifier required for the service request. The session identifier, i.e. the SessionID, may determine the topic type associated with the service request by parsing the bit value of the field corresponding to the SessionID.
Optionally, the topic type may be determined by a client type issued by the service request, and the service distribution middleware may determine, by parsing a client number of the service request, a client type corresponding to the service request, and determine, based on the client type, an associated topic type.
In S1012, a pre-stored topic subscription list is queried, the processing control middleware subscribing to the topic type is determined, and the service request is sent to the processing control middleware.
In this embodiment, service requests of different topic types may be distributed in response through different processing control middleware, based on which, the processing control middleware may establish a subscription-distribution relationship with the service distribution middleware, and after receiving a service request of a corresponding topic type, the service distribution middleware may perform a distribution operation of the service request to the processing control middleware subscribed to the topic type, thereby being capable of directionally sending the service request of an associated topic type. Based on this, the service distribution middleware can determine the processing control middleware corresponding to the topic type of the service request received this time by querying the topic subscription list, and send the service request to the processing control middleware for subsequent response operation.
In the embodiment of the invention, the processing control middleware corresponding to the processing service request is determined by identifying the theme type of the service request, so that different theme types can be responded by different processing control middleware, and the coupling degree between service response flows of different theme types is reduced.

in S701, the service request is added to a to-be-processed list, and a processing order of the service request in the to-be-processed list is determined according to a receiving time of the service request.
In this embodiment, when responding to a service request, the service distribution middleware may perform processing in an asynchronous response manner, that is, after receiving the service request sent by the terminal device, add the service request to the to-be-processed list, determine a processing order of each service request according to the receiving time of each to-be-processed request, and sequentially respond to each service request.
In S702, based on the processing order, the service requests in the to-be-processed list are sequentially sent.
In this embodiment, the service distribution middleware may send each service request stored in the pending list to each process control middleware according to the determined processing order. If a plurality of processing control middleware exist in the response system of the service request, each service request can be sequentially sent to the processing control middleware corresponding to the theme type of the service request for response according to the theme type of each service request.
In the embodiment of the invention, the service request is added into the list to be processed, so that asynchronous response of the service request is realized, the data processing efficiency of a response system of the service request can be improved, and the load pressure of the system is reduced.
