20170310766
The present application relates to the field of communication technology, and in particular to a service state determining method for a service processing device and a scheduling device.
Along with the development of network communication, the demands of users on a data transmission speed and stability of internet are higher and higher. In order to meet the above demands of the users, the application of a Content Delivery Network (CDN) technology becomes wider and wider. By adopting the CDN technology, network phenomena such as a slower opening speed of a website caused by problems of cross-operator, cross-region, overlow load capacity of a server, too less widebands, or the like, can be solved, thereby realizing network accelerating.
The CDN includes a scheduling device for service scheduling, and a plurality of service processing devices, where the scheduling device is configured to receive a service request of the user, allocate a corresponding service processing device for the service request, and send the service request to the service processing device; the service processing device is configured to process the service request and realize a service corresponding to the service request.
The allocation of the corresponding service processing device for the service request by the scheduling device in the CDN is based on an operation state of the service processing device. The scheduling device detects and updates the operation state of the service processing device in the CDN, for example, through heartbeat detection or fault detection. Thus, when the scheduling device needs to allocate the service processing device for a service request, the scheduling device selects one service processing device with normal operation state from a plurality of service processing devices and allocates to the service request.
However, in real application, not all service processing devices in the CDN can process various service requests, when the service processing device allocated by the scheduling device for the service request cannot process this service request, as a result, the service requested by the service request cannot be realized, thereby the safety and stability of the CDN network are reduced and user's experience is further reduced.
The embodiments of the present application provide a service state determining method for a service processing device and a scheduling device, aiming to solve the problem in the prior art that the service processing device allocated by the scheduling device for the service request cannot process this service request.
In a first aspect, the embodiment of the present application provides a service state determining method for a service processing device, including:
sending, by a scheduling device, a service request to a service processing device;
determining, by the scheduling device, to receive a response message returned by the service processing device for the service request, and determining that a service state of the service processing device is that the service processing device can process the service request, where the response message is returned to the scheduling device after the service request is received by the service processing device in a case that the service processing device can process the service request.
In a second aspect, the embodiment of the present application further provides a non-transitory computer storage medium storing a computer executable instruction, and the computer executable instruction is set for:
sending a service request to a service processing device; and
determining to receive a response message returned by the service processing device for the service request, and determining that a service state of the service processing device is that the service processing device can process the service request, wherein the response message is returned to the scheduling device after the service request is received by the service processing device in a case that the service processing device can process the service request.
In a third aspect, the embodiment of the present application further provides a scheduling device, including at least one processor and a memory, where the memory stores a program executable by the at least one processor, and execution of the instructions by the at least one processor causes the at least one processor to:
send a service request to a service processing device; and
determine to receive a response message returned by the service processing device for the service request, and determine that a service state of the service processing device is that the service processing device can process the service request, wherein the response message is returned to the scheduling device after the service request is received by the service processing device in a case that the service processing device can process the service request.
According to the service state determining method for the service processing device and the scheduling device provided by the present application, the scheduling device can determine the service state of the service processing device by sending the service request to the service processing device and determining to receive the response message returned by the service processing device for the service request, thus, the scheduling device can allocate the service processing device for this service request according to the service state of the service processing device subsequently, thereby avoiding the problem that the service processing device allocated for the service request by the scheduling device cannot process this service request, ensuring that the service requested by the service request can be normally realized, improving the safety and stability of the network and improving user's experience.
One or more embodiments are illustrated by way of example, and not by limitation, in the figures of the accompanying drawings, wherein elements having the same reference numeral designations represent like elements throughout. The drawings are not to scale, unless otherwise disclosed.
In order to make the objective, technical solution and advantages of the embodiments of the present application more apparent, the technical solution in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the embodiments to be described are just partial embodiments of the present application instead of all embodiments. Based upon the embodiments here of the application, all of other embodiments derived by those ordinarily skilled in the art without any inventive effort shall come into the scope of the application.
According to the service state determining method for the service processing device and the scheduling device provided by the present application, the scheduling device can determine the service state of the service processing device by sending the service request to the service processing device and receiving the response message returned by the service processing device for the service request, thus, the scheduling device can allocate the service processing device for this service request according to the service state of the service processing device subsequently, thereby avoiding the problem that the service processing device allocated for the service request by the scheduling device cannon process this service request, ensuring that the service requested by the service request can be normally realized, improving the safety and stability of the network and improving user's experience.
The service state determining method for the service processing device provided by the embodiment of the present application is applicable to various networks including the scheduling device, for example, a CDN network, where the scheduling device is a device for performing resource scheduling on various services.
Step 101: a scheduling device sends a service request to a service processing device.
The service processing device can be any one service processing device in a current network, or any service processing device with a normal operation state, or a service processing device designated by the scheduling device or a user, which is not limited by the embodiment of the present application. The service processing device can be a service server, a computer and other devices capable of realizing some services, which is not limited by the embodiment of the present application.
The scheduling device can perform the step 101 by but not limited to the following two approaches:
First approach: after receiving the service request, the scheduling device stores the service request and sends the service request to the service processing device.
Second approach: the scheduling device sends a preset service request to the service processing device.
In the first approach, the moment when the scheduling device sends the service request can be after the scheduling device receives the service request, where the service request is sent by the user for realizing some type of service, at this point, the scheduling device can judge a service state of the service processing device through the service request, but the scheduling device needs to locally store the service request, for example, cache the service request to a buffer, then, after determining the service state of the service processing device, the scheduling device can continue to follow up the service state of the service processing device, and allocates the service processing device for the service request, thereby ensuring that all requested services can be realized normally.
In the second approach, the scheduling device can pre-store a template of a plurality of service requests, and the scheduling device can send any one service request to the service processing device for judging the service state of the service processing device, i.e., whether the service processing device can process the service request.
In the embodiment of the present application, the moment to perform the step 101 is not limited, in the first approach, the scheduling device can perform step 101 after receiving the service request; and in the second approach, the scheduling device can perform the step 101 in accordance with a preset period, or perform the step 101 when the operation state of the service processing device is determined to be normal, or perform the step 101 when the service processing device is started.
Optionally, in a case that the scheduling device can determine an operation state of the service processing device, before the scheduling device performs the step 101, the method further includes:
The scheduling device determines that the operation state of the service processing device is normal.
The scheduling device can determine the operation state of one service processing device through heartbeat detection or various conventional fault detection methods, which is not limited by the embodiment of the present application.
Since only the service processing device with the normal operation state can process the service request, with the method, the scheduling device can be avoided from sending the service request to the service processing device with a faulty operation state, and the resource waste of the scheduling device can be avoided.
Step 102: the scheduling device determines to receive a response message returned by the service processing device for the service request, and determines that a service state of the service processing device is that the service processing device can process the service request, where the response message is returned to the scheduling device after the service request is received by the service processing device in a case that the service processing device can process the service request.
Usually, after one service processing device receives one service request, in a case that the service processing device can process the service request, a corresponding response message is usually sent to the device sending the service request; in a case that the service processing device cannot process the service request, a notification message may be returned, or no response is made, that is, no information is returned.
Optionally, the scheduling device determines not to receive the response message returned by the service processing device, and determines that the service state of the service processing device is that the service processing device cannot process the service request. The scheduling device determines not to receive the response message returned by the service processing device in two cases: in one case, the scheduling device receives information of the service processing device but such information is not the response message; in the other case, the service processing device does not send any message to the scheduling device.
In a real application scenario, after the scheduling device sends the service request to the service processing device, there are two results: in the first result, the scheduling device receives the information sent from the service processing device; in the second result, the scheduling device does not receive any information sent from the service processing device. Obviously, under the second result, the scheduling device can determine that the service processing device cannot process the service request.
Under the first result, optionally, the step of determining to receive the response message returned by the service processing device by the scheduling device includes:
The scheduling device receives information sent from the service processing device;
The scheduling device acquires the stored response message, and matches the response message with the information; and
The scheduling device determines to receive the response message returned by the service processing device upon determining that the response message and the information are matched.
The response message corresponding to the request message is stored in the scheduling device, thus, when the information sent from the service processing device is received, it can be judged whether the information is the response message corresponding to the request message, and the service state of the service processing device can be further determined.
After the step 102, after determining the service state of the service processing device, the scheduling device stores the service state of the service processing device, thus, after receiving the service request subsequently, the scheduling device can continue to follow up the service state of the service processing device, and allocate the service processing device for the received service request.
With the method, the scheduling device can determine the service state of the service processing device when sending the service request to the service processing device and determining to receive the response message returned by the service processing device for the service request, thus, the scheduling device can allocate the service processing device for this service request according to the service state of the service processing device subsequently, thereby avoiding the problem that the service processing device allocated for the service request by the scheduling device cannot process this service request, ensuring that the service requested by the service request can be normally realized, improving the safety and stability of the network and improving user's experience.
In a real application scenario, the scheduling device can send a plurality of service requests of a plurality of service types (for example, live, on demand, etc.) to a plurality of service processing devices simultaneously, thus, the scheduling device can determine the service states of the plurality of service processing devices in processing the plurality of service types using the above method, thereby improving the working efficiency of the scheduling device in determining the service state of the service processing device.
