The specific working processes of the above-described system, module and network node may refer to the corresponding processes in the foregoing method embodiments, which are not described herein.
Nginx (engine x) is a high performance hypertext transfer protocol (Hyper Text TransferProtocol, HTTP) and reverse proxy web server, while also providing IMAP/POP3/SMTP services. In the related art, a terminal sends a request to a back-end server through a back-end server (engine x, ng ix), the back-end server processes the request and feeds back the request to the terminal through the back-end server, in the process, input/Output (I/O) devices on the back-end server are always fully loaded, and no method for effectively reducing the load condition of the I/O devices exists at present; meanwhile, in the prior art, the priority of the response cannot be distinguished, so that the user can only receive useless resources such as static files or pictures after waiting for a long time.
In addition, the existing reverse server can cause the blocking of the interface request of the normal I/O equipment under the condition that a large number of static files are received by an external malicious request, so that network attack cannot be effectively resisted, and normal feedback response cannot be realized.
In order to solve the problem that the load of a server cannot be effectively reduced in the prior art, the application provides a service transmission method as shown in fig. 2. The method comprises the steps of determining a service cache queue and determining target service in the service cache queue under the condition that the load of a server is larger than a preset threshold, and finally determining whether the load required for transmitting the target service is smaller than the current available load of the server, and if so, sending the target service to a terminal. Based on the technical scheme, the server caches the service into the service cache queue under the condition of higher load, and only sends the request which has higher priority and meets the current load requirement of the server, so that the load of the server is effectively reduced, and the occurrence of the condition of full load of the server is avoided.
As shown in fig. 2, a flowchart of a service transmission method provided in an embodiment of the present application is shown, where the service transmission method provided in the embodiment of the present application may be applied to the service transmission device shown in fig. 1, and the service transmission method provided in the embodiment of the present application may be implemented by the following steps.
S201, the service transmission device determines a service cache queue under the condition that the load of the server is larger than a preset threshold value.
The service buffer queue is used for buffering the service sent by the server to the terminal.
In one possible implementation, the server may also be understood as a reverse server, with the load of the server including the load of the I/O devices on the reverse server and other loads on the server. In this application, the load of the server will be mainly described as an example of the load of the I/O device of the server.
In a specific implementation manner, a service transmission device monitors the load condition of an I/O device, compares the load of the I/O device with a preset threshold in the service transmission device, and if the load of the I/O device is greater than or equal to the preset threshold, a server starts a service buffer queue to buffer a service currently required to be sent to a terminal into a service buffer queue.
The service transmission device monitors the load of the server, determines that the current load of the server is 50MB, compares the current load of the server with a preset threshold value 40MB, determines that the load 50MB of the server is greater than the preset threshold value 40MB, instructs the server to start a service buffer queue at this time, and buffers a plurality of services fed back by the back-end server into the service buffer queue.
Optionally, the service cached in the service cache queue includes service content, service size, and a timestamp of the service entering the cache queue.
It should be noted that, in the embodiment of the present application, the server refers to a reverse server, and the backend server is a server that processes a service request of a terminal.
S202, the service transmission device determines the target service in the service buffer queue.
The target service is a service with priority meeting preset conditions in a service cache queue.
In one possible implementation manner, the service transmission device determines the priority of each service in the service buffer queue, and determines that the service with the priority meeting the preset condition is the target service.
In one possible implementation manner, after the service transmission device sends the target service to the terminal every preset time or every time, the service transmission device recalculates the priority of each service in the service buffer queue, and redetermines the service with the current priority meeting the preset condition as the target service.
S203, the service transmission device determines whether the current available load of the server is larger than the service size of the target service.
S204, if yes, the service transmission device sends the target service to the terminal.
For example, in the case where the service transmission device determines that the current available load of the server is 30MB and the service size of the target service is 10MB, the service transmission device determines that the current available load of the server is greater than the service size of the target service. That is, the service transmission apparatus determines that the current available load of the server satisfies the requirement of transmitting the target service, and at this time, the service transmission apparatus may transmit the target service to the terminal.
Compared with the prior art, the service transmission method provided by the embodiment of the invention has the advantages that the service transmission device transmits the target service to the terminal only when the current available load of the server is larger than the service size of the target service, and the service transmission device buffers the service to the service buffer queue under the condition that the load of the server is higher, only transmits the service with higher priority and meets the current load requirement of the server, thereby effectively reducing the load of the server and avoiding the occurrence of the full load condition of the server.
In the following, a detailed description will be given of how the service transmission apparatus determines the target service in the service buffer queue in the embodiment of the present application, in connection with a specific embodiment.
Referring to fig. 2, as shown in fig. 3, how the service transmission device determines the target service in the service buffer queue may be specifically implemented by the following S301-S302, which are described in detail below:
s301, the service transmission device determines the priority of each service in the service buffer queue.
Wherein the priority is determined according to at least one of: the load value of the server, the service type of the service, the service size of the service, and the duration of the service in the cache queue.
In one possible implementation manner, the service transmission device calculates and determines the priority of each service in the service buffer queue according to at least one of the load value of the server, the service type of the service, the service size of the service and the duration of the service in the buffer queue.
In a specific implementation manner, the service transmission device determines that the sum of the first weight value, the first parameter value, the second parameter value, the third parameter value and the fourth parameter value of the ith service in the service buffer queue is the priority of the ith service.
The first weight value is the weight value of the service type of the ith service; the first parameter value is the product of the first coefficient and the load value of the server; the second parameter value is the product of the second coefficient and the load value of the server; the third parameter value is the product of the third coefficient and the service size of the ith service; the fourth parameter value is the product of the fourth coefficient and the duration of the ith service in the service buffer queue.
The load value of the server includes, as an example, a read-write margin value and a network margin value of an input-output device of the server.
Priority W of ith service i The following equation 1 is satisfied:
W i ＝E i +A*F+B*G+C*U i +D*V i equation 1
Wherein E is i A weight value for a service type denoted as i-th service; a is represented as a first coefficient; f is expressed as a read-write margin value of input-output equipment of the server; b is represented as a second coefficient; g represents the network margin of the input/output device of the serverA degree value; c is represented as a third coefficient; u (U) i A service size denoted as i-th service; d is represented as a fourth coefficient; v (V) i Denoted as the length of time that exists in the ith traffic buffer queue. The first coefficient, the second coefficient, the third coefficient and the fourth coefficient are preset values.
For example, the first coefficient, the second coefficient, the third coefficient, and the fourth coefficient may be determined according to an empirical value of an operation and maintenance person.
The service type of the service A is static file acquisition, the service type of the service B is database data acquisition, the service type of the service C is user entity operation, the weight value of the static file acquisition is 2.5, the weight value of the database data acquisition is 3.5, and the weight value of the user entity operation is 4.
At this time, the service transmission apparatus calculates the priority W of the service a according to the above formula 1 A ＝2.5+5*2mb/s+5*5mb/s+(-6)*0.5mb+0.008*1000ms＝42.5。
The service transmission device calculates the priority W of the service B B ＝3.5+5*2mb/s+5*5mb/s+(-2)*2mb+0.005*2000ms＝44.5。
The service transmission device calculates the priority W of the service C C ＝4+5*2mb/s+5*5mb/s+2*0.8mb+0.007*1500ms＝51.1。
S302, the service transmission device takes the service with the highest priority in the service buffer queue as the target service.
In combination with the example in S301, the service transmission device compares the priority 42.5 of the service a, the priority 44.5 of the service B, and the priority 51.1 of the service C to determine that the priority of the service C is the highest, and at this time, the service transmission device determines that the service C is the target service.
Based on the technical characteristics, the service transmission method provided by the application determines the priority of each service in the service buffer queue through the service transmission device, determines the service with the highest priority according to the priority of each service, and firstly feeds back the service with the highest priority when feeding back the service to the terminal, thereby ensuring the user experience of the service with the high priority.
In the above, it is described in detail how the service transmission apparatus determines the target service in the service buffer queue.
The specific implementation manner of whether the service transmission device feeds back the target service step to the terminal will be described in detail below.
As shown in fig. 4, whether the service transmission device feeds back the target service to the terminal may be specifically implemented through S401-S403, which is described in detail below:
s401, the service transmission device determines whether the available read-write margin value of the input/output device and the available network margin value of the input/output device are both larger than the service size of the target service.
In one possible implementation, the service transmission apparatus compares the available read-write margin value and the available network margin value of the input-output device with the service size of the target service, respectively, and determines whether the available read-write margin value and the available network margin value are both greater than the service size of the target service. The service size of the target service may be understood as a data size of the service, where the service size is in mb. The available read-write margin value of the input-output device can be understood as the capacity of the IO device that the server can currently provide for reading and writing, and the available network margin value of the input-output device can be understood as the network bandwidth capacity that the server can currently provide for transmission.
S402, if not, the service transmission device pauses to send the target service to the terminal.
Illustratively, in combination with the examples in S301 and S302 above, service C is a target service, and the service size of service C is 0.8MB. The service transmission device determines that the available read-write margin value of the input and output equipment is 0.5MB at the moment, the available network margin value of the input and output equipment is 15MB, compares the available read-write margin value of the input and output equipment with the service size of the service C of 0.8MB, and then compares the available network margin value of the input and output equipment of 15MB with the service size of the service C of 0.8MB.
The service transmission device determines that the available read-write margin value of the input/output equipment is 0.5MB and is smaller than the service size of the service C and is 0.8MB, and the input/output equipment cannot meet the service C, and the service transmission device delays sending the service C to the terminal.
It should be noted that, in the case where the service transmission device temporarily transmits the target service to the terminal, the service transmission device acquires the service with the second highest priority in the service transmission queue as the target service, and executes the above steps again to determine whether to transmit a new target service to the terminal.
S403, if yes, the service transmission device sends the target service to the terminal.
