Detailed Description
Exemplary embodiments of the present application are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present application to facilitate understanding, and should be considered as merely exemplary. Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Referring to fig. 1, fig. 1 is a resource allocation method provided in an embodiment of the present application, which is applied to a first electronic device, and includes:
step S101, under the condition that a job task is received, acquiring state information of a plurality of second electronic devices in a target area, wherein the state information comprises an idle resource space and historical access flow;
the first electronic device may be a server for communicating with each second electronic device, and the second electronic device may be an edge node device deployed at a different location from the target area, and the edge node device may also be a server. Job data for executing job tasks of different manufacturers can be transmitted to each second electronic device through the first electronic device. For example, when the manufacturer is an curiosity, the video resources can be stored in each second electronic device through the first electronic device, so that when the user accesses the curiosity application to play the video, the video playing service can be provided for the user through the second electronic device which is closer to the location of the user, that is, the video resources on the second electronic device are sent to the user, so that the smoothness of playing the video resources by the user is improved.
The target area may be an administrative area such as a county level, a city level, a provincial level, or a country level. The acquiring the status information of the plurality of second electronic devices in the target area may refer to acquiring the status information of all the second electronic devices in the target area.
The idle resource space may refer to a storage resource space, a broadband resource space, an interface resource, and the like of the second electronic device. The historical access flow may refer to a number of times a user accesses a second electronic device during a period of time, where the number of times the user accesses the second electronic device may be a sum of the number of times the user accesses different services on the second electronic device. For example, if a certain second electronic device is used as an edge node for jittering, alien, and vacation, the historical access flow of the second electronic device is: the sum of the number of all trembling users, lover users, vacating users accessing the second electronic device over a period of time.
The received job task may be a job task sent by a manufacturer when the edge node needs to be deployed in the target area. For example, many users in the target area need to watch the video through video software developed by company a, and company a does not deploy edge nodes in the target area, so that when users in the target area play the video through the video software of company a, the problem that the users cannot play the video due to insufficient resources often occurs. Therefore, the company a can provide services for users by means of the second electronic devices already deployed in the target area for the second electronic devices in the area a, namely, at least one target electronic device is selected from the second electronic devices in the target area, a target resource space with a fixed size is selected from the idle resource spaces of each target electronic device, and the selected target resource space is distributed to the company a, so that the company a can pre-store video resources in the target resource spaces of all the target electronic devices through the first electronic devices, and users in the subsequent area a can directly receive the video resources sent by the target electronic devices.
When the second electronic device is deployed for the first time in the target area, the second electronic device can be deployed according to the population distribution thermodynamic diagram in the target area, namely, more second electronic devices are deployed in the densely populated area, and less or even no second electronic devices are deployed in the sparsely populated area.
Step S102, screening at least one target electronic device from the second electronic devices based on the state information;
when a job task is received, because not all the second electronic devices are suitable for running the job task, for example, there may be a part of second electronic devices that cannot receive a new job task due to insufficient storage resource space. Or, there may be a portion of the second electronic device that has been deployed for a relatively long time, but the historical access flow is very small, that is, it is indicated that the surrounding of the second electronic device may be too weak, and even if the job task can be deployed on the second electronic device, that is, the video resource is stored on the second electronic device, because the surrounding of the second electronic device is too weak, the user may access the service through the second electronic device, and thus the access pressure of the background server cannot be shared through the second electronic device.
Therefore, in the embodiment of the present application, the second electronic device with more idle resources and more historical access traffic in the target area may be selected as the target electronic device.
Step S103, selecting a target resource space with a fixed size from the idle resource spaces of each target electronic device, and allocating the selected target resource space to the job task.
The resource space of each target electronic device can be divided into a plurality of target resource spaces in advance, and each target resource space can be used as a working space of a working task of one manufacturer, so that each target electronic device can be used as an edge node of a plurality of manufacturers at the same time.
The idle resource space may refer to a resource space that does not currently have a job task. It should be noted that, after a certain target resource space is used as a job space of a certain job task, if the target resource space is not reassigned to an idle space, the target resource space is no longer used as a job space of another job task, and even if the job task is not executed currently in the target resource space, the target resource space cannot be used as a job space of another job task. And executing the new job task by the target resource space until the target resource space is reassigned to the idle space and a new job task is reassigned to the target resource space.
The above-mentioned target resource space with a fixed size may refer to a resource space with a fixed size, such as a storage resource space of 100Mbps and a broadband resource space of 500G, that is, a space with a size of 100Mbps is divided from the remaining storage space of the target electronic device, and a space with a size of 500G is divided from the remaining broadband resource space of the target electronic device as the target resource space.
In this embodiment, by deploying a plurality of second electronic devices as edge nodes in the target area in advance, when a manufacturer needs to provide services to a user by using the edge nodes, it is only necessary to select at least one target electronic device from the plurality of second electronic devices, and select a target resource space with a fixed size from each target electronic device as a working space of the manufacturer. When the vendor does not need to use the edge node any more due to service change, the target resource space in each target electronic device can be directly released to the idle resource space, so that the target resource space can be conveniently used as the working space of other vendors. Therefore, when different manufacturers need to provide services for users by using the edge nodes, only a certain resource space is needed to be divided from the target electronic equipment, node equipment is not needed to be deployed each time, and when the services are changed, only the working space is needed to be released, and the problem that the node equipment is discarded is avoided, so that the problem of resource waste in the process of providing services for users by using the edge nodes is solved.
Optionally, the idle resource space includes an idle storage resource space and an idle broadband resource space, and the screening at least one target electronic device from the plurality of second electronic devices based on the status information includes:
respectively calculating a grading value of each second electronic device based on the idle storage resource space, the idle broadband resource space and a heat value, wherein the heat value is a value calculated based on the historical access flow;
and respectively determining the first N second electronic devices with higher scoring values in the plurality of second electronic devices as the target electronic device, wherein N is an integer greater than or equal to 1.
In this embodiment, each second electronic device is scored based on the idle storage resource space, the idle broadband resource space and the popularity value, and the first N second electronic devices with higher scoring values in the plurality of second electronic devices are respectively determined as the target electronic devices. Therefore, the screened target electronic equipment can be ensured to be the second electronic equipment with more residual storage resources, more residual broadband resources and more visitor numbers in the target area, so that the service effect for users is improved.
Optionally, the calculating the score value of each second electronic device based on the idle storage resource space, the idle broadband resource space and the heat value includes:
calculating a scoring value for each of the second electronic devices according to the following formula:
wherein S is the scoring value, lambda is the adjustment factor, andfor values between 0 and 1 obtained after normalization of the heat values, the +.>For values between 0 and 1 obtained after normalizing the size of the free memory resource space, the +.>And (3) obtaining a numerical value between 0 and 1 after normalizing the size of the idle broadband resource space.
The adjustment factor may be any value between 0 and 1, and may be selected empirically to determine the weight of the heat value in the scoring value. The numerical value between 0 and 1 obtained after normalizing the heat valueThe process of (2) may be: determining a distribution range of heat values of all second electronic devices in the target area, e.g. a distribution range of [ A1, A2 ]]Then, a certain second electronic device e is obtained A heat value A3, wherein A1 is less than or equal to A3 is less than or equal to A2, and the heat value of the second electronic equipment e is normalized to be a numerical value +.>
The above determinationThe process of (1) determining the total amount of storage resource space B1 of the second electronic equipment e, and then determining the current idle storage resource space size B2 of the second electronic equipment e, then->Similarly, the above->The determination process of (1) is as follows: firstly, determining the total amount T1 of broadband resource space of the second electronic equipment e, then determining the current idle broadband resource space size T2 of the second electronic equipment e, and then +.>
In addition, the calculating the score value of each of the second electronic devices based on the idle storage resource space, the idle broadband resource space and the heat value may further include:
calculating a scoring value for each of the second electronic devices according to the following formula:
wherein λ1, λ2 and λ3 are adjustment factors between 0 and 1, respectively.
The difference between this embodiment and the above embodiment is that weights are set for the idle storage resource space, the idle broadband resource space, and the heat value, respectively, and a more reasonable scoring value is calculated according to the importance of the idle storage resource space, the idle broadband resource space, and the heat value.
In addition, the calculating the score value of each of the second electronic devices based on the idle storage resource space, the idle broadband resource space and the heat value may further include:
calculating a scoring value for each of the second electronic devices according to the following formula:
this implementation differs from the above-described embodiment in that each second electronic device is scored taking into account only the free storage resource space and the free broadband resource space.
Optionally, before calculating the score value of each of the second electronic devices based on the idle storage resource space, the idle broadband resource space and the heat value, the method further includes:
determining a first target device set H, wherein the first target device set H comprises state information of first M second electronic devices with higher historical access flow in the plurality of second electronic devices;
acquiring position information of each of the plurality of second electronic devices;
calculating the heat value of each of the second electronic devices according to the following formula:
wherein the Hot e The target second electronic device is any one of the plurality of second electronic devices, and the |P is the heat value of the target second electronic device e -P h I is a distance value between the target second electronic device and any second electronic device in the first target device set H, and P is e -P h The units of l are kilometers.
Specifically, the plurality of second electronic devices may be ordered based on access traffic of the plurality of second electronic devices, so as to select first M second electronic devices with higher heat from the plurality of second electronic devices, and store state information of the selected first M second electronic devices into the first target device set H. After the plurality of second electronic devices are ranked, the state information of the first 10% of the second electronic devices ranked first is selected and stored in the first target device set H.
Because the second electronic devices in the first target device set H are edge nodes with higher heat, the second electronic devices in the first target device set H are likely to be located in areas with higher people flow density. Correspondingly, if the other second electronic devices f outside the first target device set H are closer to the second electronic devices in the first target device set H, the likelihood that the second electronic devices f are located in the area with higher people flow density is higher, and accordingly the heat value is higher. Conversely, if the second electronic device f is further away from the second electronic devices in the first target device set H, it is indicated that the second electronic device f is less likely to be located in the area with higher people flow density, and accordingly the heat value is lower.
Thus, in calculating the heat value of the plurality of second electronic devices, the heat value of the second electronic device c to be calculated may be determined based on the relative distance between the second electronic device c to be calculated and each second electronic device of the first target device set H. For example, when the second electronic device c to be calculated is a certain second electronic device in the first target device set H, the distance between the second electronic device c and itself approaches 0, soNecessarily there is an |P e -P h I approaches 0, at which time lg P e -P h I approaches negative infinity, therefore, after summation +.>Approaching infinity, illustrating the second power in the first target device set HThe heat value of the sub-device c approaches positive infinity, i.e. the higher the corresponding heat value. When the distance between a certain second electronic device f and each second electronic device in the first target device set H is relatively long, for example, the distance between the second electronic device f and each second electronic device in the first target device set H is more than 10 km, i.e. & lt & gt>All |P in (3) e -P h The I are all greater than 10, i.e. +.>All (-lg|P) e -P h I) are negative values, in which case the sum is then given by +.>And also negative, indicating that the lower the heat of the second electronic device f. Based on this, by the formula- >After the heat value of each second electronic device is calculated, the heat value of each second electronic device can be judged according to the magnitude of the value.
Optionally, the method further comprises:
determining a second target electronic device, wherein the second target electronic device is a second electronic device which synchronously runs at least two different job tasks in the plurality of second electronic devices;
in the case that the at least two different job tasks include a first job task and a second job task, assigning a fixed-size first space in a first target resource space to the second job task;
the first job task is a job task of which the utilization rate of the target resource space in a first preset time period is smaller than a first preset value, the second job task is a job task of which the utilization rate of the target resource space in the first preset time period is larger than or equal to the first preset value, and the utilization rate of the target resource space in the first preset time period is continuously increased; the first target resource space is a job space of the first job task, and the second target resource space is a job space of the second job task.

The second job task is a job task in which the usage rate of the target resource space in the first preset time period is greater than or equal to a first preset value, and the usage rate of the target resource space in the first preset time period is continuously increased, and may refer to: the utilization rate of the storage resource of the second job task in the past month is higher than 50%, the utilization rate of the broadband resource is also higher than 50%, the utilization rate of the storage resource in each day is higher than the utilization rate of the storage resource in the previous day, and the utilization rate of the broadband resource in each day is also higher than the utilization rate of the broadband resource in the previous day.
The usage of the storage resource of the first job task may refer to a ratio between a space actually occupied by executing the first job task and a first target resource space. The usage of the storage resources may be calculated every thirty minutes and then averaged for a day to obtain the storage resource usage for that day. Similarly, the calculation process of the utilization rate of the storage resources of the job tasks other than the first job task may be calculated according to the above-described method. In addition, the calculation process of the utilization rate of the broadband resource may also be calculated according to the above method.
The first space may be 10% of the first target resource space.
In this embodiment, by determining the second target electronic devices that simultaneously run at least two job tasks, then monitoring the usage rate of the target resource space of each job task in each second target electronic device, and transferring the space of the first job task whose usage rate of the target resource space is low to the second job task whose usage rate of the target resource space is high and whose usage rate of the target resource space is continuously rising. Therefore, the space occupied by each operation task in the second target electronic equipment is dynamically conditioned. And each job task is ensured to normally run on the second target electronic equipment, so that the utilization rate of resources is improved.

selecting a fourth target resource space with a fixed size in the fourth target electronic equipment, and distributing the fourth target resource space to the third job task;
and distributing a third target resource space in the third target electronic equipment to an idle resource space of the third target electronic equipment, wherein the third target resource space is a job space of the third job task.
