Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that in the examples of the present application, numerous technical details are set forth in order to provide a better understanding of the present application. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present application, and the embodiments may be mutually incorporated and referred to without contradiction.
The embodiment of the present application relates to a resource scheduling method, which is applied to a scheduling center of a content delivery CDN network, and specifically includes the following steps, as shown in fig. 1.
Step 101, receiving a resource request of a terminal, wherein the resource request is sent to a scheduling center by a high-allocation device in a CDN network when schedulable service resources are insufficient.
In an example implementation, the resource request of the terminal received by the scheduling center is forwarded to the scheduling center by the high-provisioning device in the CDN network, and when the high-provisioning device receives the resource request sent by the terminal, it may first determine whether service resources that can be scheduled in the current high-provisioning device are sufficient, and when schedulable service resources in the high-provisioning device are insufficient, it indicates that the high-provisioning device cannot process the resource request, and at this time, the high-provisioning device sends the resource request to the scheduling center.
In an example implementation, a high-provisioned device in a CDN network refers to a device in the CDN network that is configured relatively high, or a device in the CDN network that can obtain resources across the network.
And step 102, selecting schedulable low-configuration equipment from the low-configuration equipment according to the pre-stored equipment information of the low-configuration equipment in the CDN.
In an example implementation, the low-profile device in the CDN network refers to a device that is set by a user in the CDN network in a customized manner, or a device that is configured relatively lower in the CDN network, or a device that cannot acquire resources across networks in the CDN network.
In an example implementation, each low-profile device in the CDN network reports current device information to the scheduling center in real time, where the device information reported by each low-profile device includes a device identifier, a current request number, a device weight, and the like, where the device identifier is a Uniform Resource Locator (URL), that is, a network address of the low-profile device; the equipment weight is generated by the scheduling center according to the equipment monitoring information or the equipment quality index reported by the low-set equipment, the equipment weight represents the number of the requests which can be called by the low-set equipment, the higher the equipment weight is, the higher the number of the requests which can be called by the low-set equipment is, the lower the equipment weight is, and the fewer the number of the requests which can be called by the low-set equipment is; the cache information is not contained in each low-configuration device, so that whether the low-configuration device has a cache can be judged according to whether the device information reported by each low-configuration device contains the cache information; in addition, the reported device information may also include device operation information such as process information.
In an example implementation, after receiving a resource request sent by a high-configuration device, a scheduling center may select one schedulable low-configuration device from low-configuration devices according to device information of the low-configuration devices, and when selecting the schedulable low-configuration device, the scheduling center may select only according to a current request number, may select only according to a device weight, may select according to the current request number and the device weight, may select according to the current request number, the device weight, and cache information, where the selection is not limited, and any one or a combination of several pieces of device information may be used as a basis for selecting the schedulable low-configuration device.
In an exemplary implementation, the resource request is only a trigger mechanism for triggering the scheduling center to select the schedulable low-profile device according to the device information of each low-profile device, and is not used as a basis for selecting the schedulable low-profile device.
And 103, sending the device identifier of the schedulable low-allocation device to the terminal so that the terminal can obtain the service resource of the schedulable low-allocation device.
In an example implementation, after selecting the schedulable low-profile device, the scheduling center sends the device identifier of the schedulable low-profile device to the high-profile device, the high-profile device forwards the device identifier to the terminal, and the terminal accesses the schedulable low-profile device according to the device identifier (i.e., the URL address) after receiving the device identifier of the schedulable low-profile device, so as to obtain the service resource on the schedulable low-profile device.
In the embodiment of the application, a resource request of a terminal is received on a scheduling center of a content delivery CDN network, wherein the resource request is sent to the scheduling center by a high-configuration device in the CDN network when schedulable service resources are insufficient; selecting schedulable low-configuration equipment from the low-configuration equipment according to prestored equipment information of the low-configuration equipment in the CDN network; and sending the device identification of the schedulable low-allocation device to the terminal so that the terminal can obtain the service resource of the schedulable low-allocation device. The scheduling method and the scheduling device for the high-configuration equipment can schedule the service resources of the low-configuration equipment in the CDN when the schedulable service resources of the high-configuration equipment are insufficient, can fully utilize all the service resources in the CDN, do not increase the operation cost of the CDN on the premise of ensuring the service quality, and avoid the technical problem that the operation cost of the CDN is high due to the fact that the service resources are acquired across the network and the service resources of the low-configuration equipment are idle when the high-configuration equipment resources are insufficient in the prior art.
The embodiment of the present application relates to a resource scheduling method, which is applied to a scheduling center of a content delivery CDN network, and specifically includes the following steps, as shown in fig. 2.
In an exemplary implementation, this step is substantially the same as step 101 in the embodiment of the present application, and is not repeated here.
In an example implementation, a mapping relationship between the device weight and the schedulable request information may be preset in the scheduling center, where the schedulable information is strength of the low-device scheduling request, such as: normal scheduling, more scheduling, less scheduling, no scheduling and the like; the strength of the current scheduling request of the low-configuration device can be obtained according to the weight value of the low-configuration device.
In an example implementation, the device weight of the low-configuration device may be generated according to device monitoring information reported by the low-configuration device, and when the device monitoring information indicates that the low-configuration device is a normal low-configuration device, the device weight of the low-configuration device may be a first device weight, and the first device weight may be preset to 10; when the device monitoring information indicates that the low-configuration device is an abnormal low-configuration device, setting the device weight value of the low-configuration device as a second device weight value, wherein the first device weight value can be preset to be 0; after the abnormal low-level equipment removes the abnormality, the weight of the equipment can be adjusted according to the weight increasing function, the time for removing the abnormality and the current time; the expression of the weight increasing function is as follows: y is 2XAnd +2, Y is a device weight, and X is a time interval between the time for removing the exception and the current time.
In an example implementation, the device monitoring information may be device alive status, device hardware status, and device software status; and only when the equipment survival state is the equipment survival state, the equipment hardware state is the hardware normal state and the equipment software state is the software normal state, the low-configuration equipment is indicated to be normal low-configuration equipment.
In an example implementation, when there is an abnormality in any one of the device alive state, the device hardware state, and the device software state of the low-configuration device, it is determined that the low-configuration device is an abnormally low-configuration device, at this time, it is detected whether the current request number on the abnormally low-configuration device is zero, and for an abnormally low-configuration device with a current request number that is not zero, the current request on the abnormally low-configuration device is dispatched to a low-configuration device in the schedulable low-configuration device set to ensure normal operation of requests on each low-configuration device.
In an example implementation, the device survival status is one of device survival, device down, device network outage and device offline, the device hardware status is one of hardware normal, disk fault, memory fault, motherboard fault, network card fault and Central Processing Unit (CPU) fault, the device software status is one of software normal and cache service software fault, the scheduling center considers the low-profile device to be normal only when the device survival status is device survival, the device hardware status is hardware normal and the device software status is software normal, and the other situations are considered the low-profile device to be abnormal.
In an example implementation, the device weight of the low-configuration device may be generated according to a device quality indicator reported by the low-configuration device, and when the device quality indicator indicates that the low-configuration device is a high-quality low-configuration device, the device weight of the low-configuration device may be set to be a first device weight, and the first device weight may be preset to be 10; when the equipment quality index indicates that the low-quality equipment is low-quality low-distribution equipment, generating an equipment weight according to a weight decreasing function, the generation time of the equipment quality index and the current time; wherein, the expression of the weight decreasing function is: y10 x (1/2)XY is the equipment weight, and X is the time interval between the generation time of the equipment quality index and the current time; after the quality of the low-quality low-configuration equipment is recovered (the low-quality equipment reported by the low-quality low-configuration equipment is not received within the preset time)Quality index, or quality index of high-quality equipment reported by low-quality and low-set equipment is received), and the weight of the equipment can be adjusted according to the weight increasing function, the abnormal time removal time and the current time; the expression of the weight increasing function is as follows: y is 2X+2, Y is the device weight, X is the time interval between the time of quality recovery and the current time.
In an example implementation, the device quality index refers to the rate at which requests are processed by the low-profile device, as can be seen from the relationship between the number of requests and the quality index given in fig. 2 a: when the number of requests increases, the corresponding equipment quality index decreases; thus, a device quality threshold (e.g., 700kp/s) may be set; when the equipment quality index of the low-equipment is larger than the equipment quality threshold, the low-equipment is indicated to be high-quality low-equipment; and when the equipment quality index of the low-configuration equipment is smaller than the equipment quality threshold, the low-configuration equipment is indicated to have a low rate of processing requests, the low-configuration equipment is a low-quality low-configuration equipment, the allocation requests of the low-configuration equipment are stopped within a certain time period, so that the request number of the low-configuration equipment starts to decrease. The service request is controlled to be served on the low-configuration equipment through the equipment quality index, and the service of the low-configuration equipment can be effectively utilized to a great extent.
In an example implementation, after receiving the device monitoring information or the device quality index, the scheduling center does not generate a device weight, directly screens a schedulable low-configuration device set (composed of normal low-configuration devices or high-quality low-configuration devices) from the low-configuration devices according to the device monitoring information or the device quality index, and then selects a schedulable low-configuration device from the schedulable low-configuration device set according to the current number of requests.
And step 203, selecting schedulable low-allocation equipment from the low-allocation equipment according to the current request number and the schedulable request information.
In an example implementation, each low-allocation device may be classified according to schedulable request information, and taking the schedulable request information as normal scheduling, multi-scheduling, less scheduling, and non-scheduling as an example, each low-allocation device may be divided into a multi-scheduling device set, a normal scheduling device set, a less-scheduling device set, and a non-scheduling device set; preferentially scheduling the equipment in the multi-scheduling equipment set, sequencing all low equipment in the multi-scheduling equipment set from small to large according to the current request number, and preferentially selecting the low equipment with the minimum current request number as the schedulable low-allocation equipment; and if the schedulable low-level equipment is not selected from the multi-scheduling equipment set, selecting from the normal scheduling equipment set, and so on.
And step 204, sending the device identifier of the schedulable low-allocation device to the terminal, so that the terminal can obtain the service resource of the schedulable low-allocation device.
In an exemplary implementation, this step is substantially the same as step 103 in the embodiment of the present application, and is not repeated here.
In the embodiment of the present application, on the basis of other embodiments, it may be determined whether to schedule a request to the low-configuration device according to the device state of each low-configuration device, so as to ensure stable service on each low-configuration device.
The embodiment of the present application relates to a resource scheduling method, which is applied to a scheduling center of a content delivery CDN network, and specifically includes the following steps, as shown in fig. 3.
In an exemplary implementation, this step is substantially the same as step 101 in the embodiment of the present application, and is not repeated here.
In an example implementation, the cache information is not provided for each low-profile device, and therefore, the low-profile devices may be divided into a set of cached low-profile devices and a set of uncached low-profile devices according to whether the device information in the low-profile devices includes the cache information.
And step 303, selecting schedulable low-configuration equipment from the buffered low-configuration equipment set according to the equipment information when the buffered low-configuration equipment set is not empty.
In an example implementation, after the classification is performed according to the cache information, a low-configuration device in the cache low-configuration device set is preferentially selected as a schedulable low-configuration device; selecting schedulable low-set equipment according to other equipment information except the cache information of each low-set equipment in the cached low-set equipment set
And step 304, selecting schedulable low-configuration equipment from the non-buffer low-configuration equipment set according to the equipment information when the buffer low-configuration equipment set is empty.
In an example implementation, when the partitioned set of low-configuration devices with cache is empty, that is, all the low-configuration devices in the set of schedulable low-configuration devices are low-configuration devices without cache information, the schedulable low-configuration devices are selected according to the device information of each low-configuration device in the set of no cache low-configuration devices except the cache information.
In an exemplary implementation, this step is substantially the same as step 103 in the embodiment of the present application, and is not repeated here.
In the embodiment of the application, on the basis of other embodiments, whether to schedule a request to the low-profile device may be determined according to whether the low-profile device has a cache, and a content scheduling manner is adopted for each low-profile device, so that the access rate of service resources may be increased, and the back-source bandwidth of the CDN network may be reduced.
The embodiment of the present application relates to a resource scheduling method, which is applied to a high-allocation device of a content delivery CDN network, and specifically includes the following steps, as shown in fig. 4.
In an example implementation, after a terminal generates a resource request, a user may analyze a domain name of a high-provisioning device from the resource request, and the terminal may access the high-provisioning device according to the domain name of the high-provisioning device and send the resource request to the high-provisioning device while accessing the high-provisioning device.
In an example implementation, after receiving the resource request, the high-allocation device may first determine its schedulable service resource, and when the schedulable service resource is insufficient, send the resource request to the scheduling center, so that the scheduling center may select a schedulable low-allocation device from the low-allocation devices according to the device information of the low-allocation devices to schedule the service resource of each low-allocation device in the CDN network, thereby avoiding the high-allocation device from acquiring the service resource across networks.
And step 403, receiving the device identifier of the schedulable low-allocation device returned by the scheduling center, and sending the device identifier to the terminal, so that the terminal can obtain the service resource of the schedulable low-allocation device.
In an example implementation, after selecting a schedulable low-profile device, a scheduling center sends a device identifier of the schedulable low-profile device to a high-profile device, the high-profile device forwards the device identifier to a terminal after receiving the device identifier, and the terminal accesses the schedulable low-profile device according to the device identifier (i.e., a URL address) after receiving the device identifier of the schedulable low-profile device, so as to obtain a service resource on the schedulable low-profile device.
According to the embodiment of the application, a resource request of a terminal is received on a high-distribution device of a content delivery CDN network; when schedulable service resources are insufficient, sending a resource request to a scheduling center of the CDN, so that the scheduling center selects schedulable low-allocation equipment from the low-allocation equipment according to prestored equipment information of the low-allocation equipment in the CDN; and receiving the equipment identifier of the schedulable low-allocation equipment returned by the scheduling center, and sending the equipment identifier to the terminal so that the terminal can obtain the service resource of the schedulable low-allocation equipment. The scheduling method and the scheduling device for the high-configuration equipment can schedule the service resources of the low-configuration equipment in the CDN when the schedulable service resources of the high-configuration equipment are insufficient, can fully utilize all the service resources in the CDN, do not increase the operation cost of the CDN on the premise of ensuring the service quality, and avoid the technical problem that the operation cost of the CDN is high due to the fact that the service resources are acquired across the network and the service resources of the low-configuration equipment are idle when the high-configuration equipment resources are insufficient in the prior art.
An embodiment of the present application relates to a resource scheduling method, which is applied to a terminal, and as shown in fig. 5, specifically includes the following steps.
In an example implementation, a user operates on an interactive interface provided by a terminal, the terminal generates a resource request according to operation information of the user, and the high-profile device domain name is analyzed from the resource request.
In an example implementation, after acquiring a domain name of a high-configuration device, a terminal accesses the high-configuration device according to the domain name of the high-configuration device, and sends a resource request to the high-configuration device while accessing to acquire a resource on the high-configuration device, the high-configuration device first determines a schedulable service resource of the high-configuration device after receiving the resource request, and when the schedulable service resource is sufficient, the high-configuration device responds to the resource request to allocate the corresponding service resource to the terminal; when schedulable service resources are insufficient, the high-configuration equipment does not need to acquire resources across the network but forwards the resource request to the scheduling center, the scheduling center selects schedulable low-configuration equipment from the low-configuration equipment according to the equipment information of the low-configuration equipment to schedule the service resources of the low-configuration equipment in the CDN, and the scheduling center simultaneously returns the equipment identifier of the schedulable low-configuration equipment to the high-configuration equipment and then sends the equipment identifier to the terminal.
In an example implementation, after receiving a device identifier of a schedulable low-configuration device sent by a high-configuration device, a terminal accesses the schedulable low-configuration device according to the device identifier (i.e., a URL address) to obtain a service resource on the schedulable low-configuration device.
