Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. However, it will be understood by those of ordinary skill in the art that in various embodiments of the present application, numerous specific details are set forth in order to provide a thorough understanding of the present application. The claimed application may be practiced without these specific details and with various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not be construed as limiting the specific implementation of the present application, and the embodiments can be mutually combined and referred to without contradiction.
The embodiment of the application relates to a resource scheduling method which is applied to a scheduling center of a content delivery CDN (content delivery CDN) network, as shown in fig. 1, and specifically comprises the following steps of.
Step 101, receiving a resource request of a terminal, wherein the resource request is sent to a dispatching center when a dispatchable service resource is insufficient by high-allocation equipment in a CDN (content delivery network).
In an example implementation, when a high-allocation device in the CDN network forwards a resource request of a terminal received by the scheduling center to the scheduling center, the high-allocation device first determines whether service resources available for scheduling in the current high-allocation device are sufficient or not when the service resources available for scheduling in the high-allocation device are insufficient, which indicates that the high-allocation device cannot process the resource request, and at this time, the high-allocation device sends the resource request to the scheduling center.
In an example implementation, a high-profile device in a CDN network refers to a device in the CDN network that is configured relatively higher, or a device in the CDN network that may acquire resources across networks.
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 in the CDN network that is set by user definition, or a device in the CDN network that is configured relatively low, or a device in the CDN network that cannot acquire resources across networks.
In an example implementation, each low-profile device in the CDN network may report 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 refers to a uniform resource locator (Uniform Resource Locator, abbreviated as URL) of the low-profile device, that is, a network address of the low-profile device; the equipment weight is generated by the dispatching center according to equipment monitoring information or equipment quality indexes reported by low-configuration equipment, the equipment weight represents the adjustable request number of the low-configuration equipment, the higher the equipment weight is, the higher the adjustable request number of the low-configuration equipment is, the lower the equipment weight is, and the lower the adjustable request number of the low-configuration 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-allocation device, the scheduling center selects one schedulable low-allocation device from the low-allocation devices according to the device information of each low-allocation device, and when selecting the schedulable low-allocation device, the scheduling center may select the schedulable low-allocation device according to the current request number, the device weight, the current request number and the device weight, or the current request number, the device weight and the cache information, which is not limited herein, and any one or a combination of several types of the device information may be used as a basis for selecting the schedulable low-allocation device.
In an example implementation, the resource request is only a trigger mechanism, which is used to trigger the scheduling center to select the schedulable low configuration device according to the device information of each low configuration device, and is not used as a basis for selecting the schedulable low configuration device.
And step 103, the equipment identification of the schedulable low-configuration equipment is sent to the terminal so that the terminal can acquire the service resources of the schedulable low-configuration equipment.
In an example implementation, after selecting the schedulable low-configuration device, the scheduling center sends the device identifier of the schedulable low-configuration device to the high-configuration device, the high-configuration device forwards the device identifier to the terminal, and the terminal accesses the schedulable low-configuration device according to the device identifier (i.e., URL address) after receiving the device identifier of the schedulable low-configuration device, thereby obtaining the service resource on the schedulable low-configuration device.
In the embodiment of the application, on a dispatching center of a content delivery CDN network, a resource request of a terminal is received, wherein the resource request is sent to the dispatching center when a high-allocation device in the CDN network is insufficient in schedulable service resource; 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; and sending the equipment identifier of the schedulable low-configuration equipment to the terminal so that the terminal can acquire the service resource of the schedulable low-configuration equipment. The application can schedule the service resources of the low-allocation equipment in the CDN network when the schedulable service resources of the high-allocation equipment are insufficient, can fully utilize all the service resources in the CDN network, does not increase the operation cost of the CDN network on the premise of ensuring the service quality, and avoids the technical problem of high operation cost of the CDN network caused by idle of the cross-network acquisition service resources and the service resources of the low-allocation equipment when the resources of the high-allocation equipment are insufficient in the prior art.
The embodiment of the application relates to a resource scheduling method which is applied to a scheduling center of a content delivery CDN (content delivery CDN) network, as shown in fig. 2, and specifically comprises the following steps.
In step 201, a resource request of a terminal is received, where the resource request is sent to a dispatching center when a dispatchable service resource is insufficient by a high-allocation device in the CDN network.
In an exemplary implementation, the step is substantially the same as step 101 in the embodiment of the present application, and is not described herein.
Step 202, determining schedulable request information of each low-profile device according to the device weight value in the device information of each low-profile device in the CDN network.
In an example implementation, a mapping relationship between a device weight and schedulable request information may be preset in a scheduling center, where the schedulable request information refers to a strength of a scheduling request of a low-profile device, such as: normal scheduling, multi-scheduling, few scheduling, non-scheduling, etc.; the strength of the current scheduling request of the low-profile device can be obtained according to the size of the device weight of the low-profile device.
In an example implementation, the device weight of the low-profile device may be generated according to device monitoring information reported by the low-profile device, and when the device monitoring information indicates that the low-profile device is a normal low-profile device, the device weight of the low-profile device may be set as a first device weight, where the first device weight may be preset to 10; when the equipment monitoring information indicates that the low-configuration equipment is abnormal low-configuration equipment, the equipment weight equipment of the low-configuration equipment is taken as a second equipment weight, and the first equipment weight can be preset to be 0; after the abnormal low-profile equipment releases the abnormality, the weight of the equipment can be adjusted according to the weight increment function, the abnormality release time and the current time; the expression of the weight increment function is as follows: y= X +2, where Y is a device weight, and X is a time interval between a time of removing an anomaly and a current time.
In an example implementation, the device monitoring information may be a device survival state, a device hardware state, and a device software state; only when the device survival state is device survival, the device hardware state is hardware normal and the device software state is software normal, the low-profile device is a normal low-profile device.
In an example implementation, when any one of the device survival state, the device hardware state and the device software state of the low-profile device is abnormal, the low-profile device is an abnormal low-profile device, at this time, whether the current request number on the abnormal low-profile device is zero is detected, and when the current request number is not zero, the current request on the abnormal low-profile device is scheduled to the low-profile device in the schedulable low-profile device set, so as to ensure that the requests on the low-profile devices are normally performed.
In an example implementation, the device surviving state is one of device surviving, device downtime, device disconnection and device disconnection, the device hardware state is one of hardware normal, disk failure, memory failure, motherboard failure, network card failure and central processing unit (central processing unit, CPU) failure, the device software state is one of software normal and cache service software failure, and the scheduling center considers the low-configuration device normal only when the device surviving state is device surviving, the device hardware state is hardware normal and the device software state is software normal, and the rest conditions consider the low-configuration device abnormal.
In an example implementation, the device weight of the low-profile device may be generated according to a device quality indicator reported by the low-profile device, and when the device quality indicator indicates that the low-profile device is a high-quality low-profile device, the device weight of the low-profile device may be set to a first device weight, where the first device weight may be preset to 10; when the equipment quality index shows that the low-quality equipment is low-quality equipment, generating equipment weight according to a weight decreasing function, the generation time of the equipment quality index and the current time; the expression of the weight decreasing function is as follows: y=10×1/2× X, Y is a device weight, and X is a time interval between a generation time and a current time of a device quality index; after the quality of the low-quality low-configuration equipment is recovered (the low-quality equipment quality index reported by the low-quality low-configuration equipment is not received in the preset time or the high-quality equipment quality index reported by the low-quality low-configuration equipment is received), the equipment weight can be adjusted according to the weight increasing function, the abnormal relieving time and the current time; the expression of the weight increment function is as follows: y= X +2, Y is the device weight, and 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 the low-profile device processes requests, as can be seen from the number of requests versus the quality index given in fig. 2 a: when the request number increases, the corresponding equipment quality index decreases; thus, a device quality threshold (e.g., 700 kp/s) may be set; when the equipment quality index of the low-quality equipment is larger than the equipment quality threshold, indicating that the low-quality equipment is high-quality low-quality equipment; when the equipment quality index of the low-allocation equipment is smaller than the equipment quality threshold, the low-allocation equipment is low in processing request rate, and the low-allocation equipment stops allocating requests within a certain time period, so that the request number of the low-allocation equipment starts to be reduced, the quality index of the low-allocation equipment is gradually increased after the request number is reduced from the corresponding equipment quality index, and the equipment weight of the low-allocation equipment is gradually increased after the equipment quality index is increased, so that the request number scheduled on the low-allocation equipment is also gradually increased. The service request is controlled to be served on the low-configuration equipment through the equipment quality index, so that the service of the low-configuration equipment can be 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 the schedulable low-configuration device from the schedulable low-configuration device set according to the current request number.
And 203, selecting the schedulable low-configuration equipment from the low-configuration equipment according to the current request number and the schedulable request information.
In an example implementation, the low-configuration devices may be classified according to the schedulable request information, and the schedulable request information is taken as a normal scheduling, a multi-scheduling, a few scheduling, and a non-scheduling, and the low-configuration devices may be classified into a multi-scheduling device set, a normal scheduling device set, a few scheduling device set, and a non-scheduling device set; the method comprises the steps of preferentially scheduling equipment in a multi-scheduling equipment set, sequencing low-allocation equipment in the multi-scheduling equipment set according to the current request number from small to large, and preferentially selecting low-allocation equipment with the minimum current request number as schedulable low-allocation equipment; if no schedulable low configuration device is selected from the multi-scheduling device set, selecting from the normal scheduling device set, and so on.
And step 204, the equipment identifier of the schedulable low-configuration equipment is sent to the terminal so that the terminal can acquire the service resources of the schedulable low-configuration equipment.
In an exemplary implementation, the step is substantially the same as step 103 in the embodiment of the present application, and is not described herein.
The embodiment of the application can also determine whether to schedule the request to the low-allocation equipment according to the equipment state of the low-allocation equipment on the basis of other embodiments, so as to ensure the stability of the service on the low-allocation equipment.
The embodiment of the application relates to a resource scheduling method applied to a scheduling center of a content delivery CDN (content delivery CDN) network, which specifically comprises the following steps as shown in fig. 3.
Step 301, receiving a resource request of a terminal, where the resource request is sent to a dispatching center when a dispatchable service resource is insufficient by a high-allocation device in a CDN network.
In an exemplary implementation, the step is substantially the same as step 101 in the embodiment of the present application, and is not described herein.
Step 302, dividing each low-profile device into a cached low-profile device set and a non-cached low-profile device set according to whether the device information of each low-profile device in the CDN network includes cache information.
In an example implementation, the cache information is not provided for each low-profile device, and thus, each low-profile device may be divided into a cached low-profile device set and a non-cached low-profile device set according to whether the cache information is included in the device information in each low-profile device.
Step 303, selecting the schedulable low-configuration device from the cached low-configuration device set according to the device information when the cached low-configuration device set is not empty.
In an example implementation, after categorizing the cache information, preferentially selecting low-profile devices in the cached low-profile device set as schedulable low-profile devices; selecting schedulable low-configuration equipment according to other equipment information except the cache information of each low-configuration equipment in the cache low-configuration equipment set
Step 304, when the cached low-configuration device set is empty, selecting the schedulable low-configuration device from the non-cached low-configuration device set according to the device information.
In an example implementation, when the partitioned cached low-profile device set is null, that is, all low-profile devices in the schedulable low-profile device set are low-profile devices without cache information, the schedulable low-profile devices are selected according to other device information except the cache information of each low-profile device in the non-cached low-profile device set.
And step 305, transmitting the device identification of the schedulable low-configuration device to the terminal so that the terminal can acquire the service resource of the schedulable low-configuration device.
In an exemplary implementation, the step is substantially the same as step 103 in the embodiment of the present application, and is not described herein.
According to the embodiment of the application, on the basis of other embodiments, whether the low-profile equipment has a cache or not can be determined, whether the low-profile equipment is subjected to scheduling request or not, and the low-profile equipment is subjected to content scheduling, so that the access rate of service resources can be improved, and the back source bandwidth of the CDN can be reduced.
The embodiment of the application relates to a resource scheduling method applied to high-allocation equipment of a content delivery CDN (content delivery CDN) network, which specifically comprises the following steps as shown in fig. 4.
Step 401, a resource request of a terminal is received.
In an example implementation, after the terminal generates the resource request, the user may parse the domain name of the high-configuration device from the resource request, the terminal accesses the high-configuration device according to the domain name of the high-configuration device, and sends the resource request to the high-configuration device while accessing the high-configuration device.
Step 402, when the schedulable service resources are insufficient, sending a resource request to a scheduling center of the CDN network, so that the scheduling center selects schedulable low-configuration devices from the low-configuration devices according to the pre-stored device information of the low-configuration devices in the CDN network.
In an example implementation, after receiving a resource request, the high-allocation device determines its own schedulable service resource, and when its own schedulable service resource is insufficient, the resource request is sent to a scheduling center, so that the scheduling center can select a schedulable low-allocation device from the low-allocation devices according to device information of the low-allocation devices, so as to schedule the service resource of the low-allocation devices in the CDN network, and avoid the high-allocation device from acquiring the service resource across the network.
Step 403, receiving the device identifier of the schedulable low-configuration 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-configuration device.
In an example implementation, after selecting the schedulable low-configuration device, the scheduling center sends the device identifier of the schedulable low-configuration device to the high-configuration device, the high-configuration device forwards the device identifier to the terminal after receiving the device identifier, and the terminal accesses the schedulable low-configuration device according to the device identifier (i.e. URL address) after receiving the device identifier of the schedulable low-configuration device, so as to obtain the service resource on the schedulable low-configuration device.
In the embodiment of the application, on high-allocation equipment of a content delivery CDN, a resource request of a terminal is received; when the schedulable service resources are insufficient, sending a resource request to a scheduling center of the CDN network, so that the scheduling center can select schedulable low-configuration equipment from the low-configuration equipment according to the equipment information of the low-configuration equipment in the CDN network; and receiving the equipment identifier of the schedulable low-configuration equipment returned by the scheduling center, and sending the equipment identifier to the terminal so that the terminal can acquire the service resource of the schedulable low-configuration equipment. The application can schedule the service resources of the low-allocation equipment in the CDN network when the schedulable service resources of the high-allocation equipment are insufficient, can fully utilize all the service resources in the CDN network, does not increase the operation cost of the CDN network on the premise of ensuring the service quality, and avoids the technical problem of high operation cost of the CDN network caused by idle of the cross-network acquisition service resources and the service resources of the low-allocation equipment when the resources of the high-allocation equipment are insufficient in the prior art.
The embodiment of the application relates to a resource scheduling method applied to a terminal, as shown in fig. 5, and specifically comprises the following steps.
Step 501, resolving a resource request generated by a user to obtain a domain name of a high-configuration device.
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 resolves a high-profile device domain name from the resource request.
Step 502, sending a resource request to a high-configuration device of a CDN network according to a domain name of the high-configuration device; when the schedulable service resources are insufficient, the high-allocation equipment sends a resource request to a scheduling center of the CDN network, and receives equipment identifiers of schedulable low-allocation equipment returned by the scheduling center, wherein the schedulable low-allocation equipment is selected from the low-allocation equipment according to pre-stored equipment information of the low-allocation equipment of the CDN network by the scheduling center.
In an example implementation, after acquiring the domain name of the high-allocation device, the terminal accesses the high-allocation device according to the domain name of the high-allocation device, and sends a resource request to the high-allocation device while accessing the domain name of the high-allocation device to acquire a resource on the high-allocation device, after receiving the resource request, the high-allocation device determines a self-schedulable service resource, and when the schedulable service resource is sufficient, responds to the resource request to allocate a corresponding service resource for the terminal; when the schedulable service resources are insufficient, the high-allocation equipment does not need to acquire resources across the network, but forwards the resource request to a scheduling center, the scheduling center selects schedulable low-allocation equipment from the low-allocation equipment according to equipment information of the low-allocation equipment so as to schedule the service resources of the low-allocation equipment in the CDN, and meanwhile, the scheduling center returns equipment identification of the schedulable low-allocation equipment to the high-allocation equipment and then the high-allocation equipment sends the equipment identification to the terminal.
