Detailed Description
The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those 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, applied to a first electronic device, including:
step S101, under the condition that a job task is received, state information of a plurality of second electronic devices in a target area is obtained, 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 position different from that in the target area, and the edge node device may also be a server. Job data for executing job tasks of different vendors may be transmitted to the respective second electronic devices through the first electronic device. For example, when the manufacturer is an odds and ends art, the video resource may be stored in each second electronic device through the first electronic device, so that when the user accesses the odds and ends art application to play a video, the video playing service may be provided to the user through the second electronic device that is closer to the location of the user, that is, the video resource on the second electronic device is sent to the user, so as to improve the fluency of the user in playing the video resource.
The target area may be an administrative area at a county level, a city level, a province level, or a country level. The acquiring of 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 the number of times that the user accessed the service of the second electronic device in a past period of time, where the number of times that the user accessed the service of the second electronic device may be the sum of the number of times that the user accessed different services on the second electronic device. For example, if a certain second electronic device is simultaneously used as an edge node for jittering, love and art, and Ten-news, the historical access traffic of the second electronic device is: the sum of all users of buffeting, entertainment and Tencent who access the second electronic device over a period of time in the past.
The received job task may refer to a job task sent by a vendor when the vendor needs to deploy an edge node in a target area. For example, many users in the target area need to watch videos through video software developed by company a, and company a does not deploy edge nodes in the target area, so that a problem that users in the target area cannot play videos due to insufficient resources often occurs when the users play the videos through the video software of company a. For this purpose, company a may provide services for users to the second electronic devices in area a by means of the second electronic devices already deployed in the target area, that is, at least one target electronic device is selected from the second electronic devices in the target area, a target resource space of a fixed size is selected from the idle resource spaces of each target electronic device, and the selected target resource space is allocated to company a, so that company a may store video resources in the target resource spaces of the target electronic devices in advance through the first electronic device, so that users in the subsequent area a may directly receive the video resources transmitted by the target electronic devices.
When the second electronic device is deployed in the target area for the first time, the second electronic device may be deployed according to a population distribution thermodynamic diagram in the target area, that is, more second electronic devices are deployed in an area with dense population distribution, and less or no second electronic devices are deployed in an area with sparse population distribution.
Step S102, screening out at least one target electronic device from the plurality of second electronic devices based on the state information;
when a job task is received, since not all the second electronic devices are suitable for running the job task, for example, there may be a case that some of the second electronic devices cannot receive a new job task due to insufficient storage resource space. Or, there may be a portion of the second electronic device that is already deployed for a relatively long time, but the historical access traffic is very little, which indicates that the periphery of the second electronic device may be rare, and even if the job task can be deployed to the second electronic device, that is, the video resource is stored in the second electronic device, since the periphery of the second electronic device is rare, few users may access the service through the second electronic device, and thus the access pressure of the background server cannot be shared by the second electronic device.
Therefore, in the embodiment of the 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 of the target electronic devices, and allocating the selected target resource space to the job task.
The resource space of each target electronic device may be divided into a plurality of target resource spaces in advance, and each target resource space may be used as a job space for a job task of one manufacturer, so that each target electronic device may be used as an edge node of multiple manufacturers at the same time.
The idle resource space may refer to a resource space where no job task is currently available. After a certain target resource space is defined as a work space of a certain job task, if the target resource space is not reallocated to an empty space, the target resource space is no longer defined as a work space of another job task, and cannot be defined as a work space of another job task even if the work task is not currently executed in the target resource space. The target resource space cannot execute a new job task until the target resource space is reallocated to an idle space and a new job task is reallocated to the target resource space.
The fixed-size target resource space may refer to a fixed-size resource space with a storage resource space of 100Mbps and a broadband resource space of 500G, that is, a space with a size of 100Mbps is partitioned from the remaining storage space of the target electronic device, and a 500G space is partitioned 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 serving as edge nodes in advance in a target area, when a certain vendor 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 of a fixed size from each target electronic device as a job space of the vendor. When the manufacturer no longer needs to use the edge node due to the service change, the target resource space in each target electronic device can be directly released to the idle resource space, so as to be used as the working space of other manufacturers subsequently. Therefore, when different manufacturers need to provide services for users by using the edge nodes, only a certain resource space needs to be divided from the target electronic equipment, the node equipment does not need to be deployed at each time, and when the services are changed, only the operation space needs to be released, the problem that the node equipment is discarded is avoided, and the problem of resource waste in the process of providing the services for the 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 out at least one target electronic device from the plurality of second electronic devices based on the status information includes:
respectively 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, wherein the heat value is 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 devices, wherein N is an integer greater than or equal to 1.
In this embodiment, each second electronic device is scored based on an idle storage resource space, the idle broadband resource space, and the heat value, and the first N second electronic devices with higher scoring values among the plurality of second electronic devices are respectively determined as the target electronic device. 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 visitors in the target area, and the service effect of the user 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 score value of each of the second electronic devices according to the following formula:
wherein S is the score value, λ is an adjustment factor, and
for values between 0 and 1 obtained after normalization of the heat value, the value
The value between 0 and 1 is obtained after the normalization processing is carried out on the size of the idle storage resource space
To the idle widthAnd carrying out normalization processing on the size of the resource space to obtain a value between 0 and 1.
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 score value. The value between 0 and 1 obtained after normalization of the heat value
The process of (2) may be: determining the distribution range of the heat value of all the second electronic devices in the target area, for example, the distribution range is [ A1, A2 ]]Then, a heat value A3 of a certain second electronic device e is obtained, wherein A1 is not less than A3 is not less than A2, and the value after the heat value of the second electronic device e is normalized
The above determination
Determining the total amount of the storage resource space B1 of the second electronic device e, and then determining the size B2 of the current idle storage resource space of the second electronic device e, then
In a similar manner, the above
The determination process of (2) is: determining the total amount of the broadband resource space T1 of the second electronic device e, and then determining the size of the current idle broadband resource space T2 of the second electronic device e, then
In addition, 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 may further include:
calculating a score value of each of the second electronic devices according to the following formula:
wherein λ 1, λ 2 and λ 3 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 score 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 second electronic device based on the idle storage resource space, the idle broadband resource space and the heat value may further include:
calculating a score value of each of the second electronic devices according to the following formula:
this embodiment differs from the above described embodiment in that each second electronic device is scored considering only the free storage resource space and the free broadband resource space.
Optionally, before 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, the method further includes:
determining a first target device set H, wherein the first target device set H comprises state information of the 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 HoteIs a heat value of a target second electronic device, the target second electronic device being any one of the plurality of second electronic devices, the | Pe-Ph| is a distance value between the target second electronic device and any second electronic device in the first target device set H, | Pe-PhThe unit of | is kilometer.
Specifically, the plurality of second electronic devices may be sorted based on access traffic of the plurality of second electronic devices, so that top M second electronic devices with higher popularity are selected from the plurality of second electronic devices, and status information of the selected top M second electronic devices is stored in the first target device set H. After the plurality of second electronic devices are sorted, the state information of the top 10% of the second electronic devices sorted in the top may be selected and stored in the first target device set H.
Since the second electronic device in the first target device set H is an edge node with a higher heat degree, the second electronic device in the first target device set H is likely to be located in an area with a higher people stream density. Accordingly, the closer the second electronic device f other than the first target device set H is to the second electronic device in the first target device set H, the higher the possibility that the second electronic device f is located in the region with the higher density of the stream of people, and accordingly the higher the heat value. Conversely, if the second electronic device f is farther from the second electronic devices in the first target device set H, the probability that the second electronic device f is located in the region with higher density of the stream of people is smaller, and the heat value is correspondingly lower.
Therefore, when calculating the heat values 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 of the second electronic devices of the first target device set H. For example, when the second electronic device c to be calculated is a certain one of the first set of target devices HThe distance between the second electronic device c and itself is close to 0 when the second electronic device is operated, so that the distance between the second electronic device c and itself is close to 0
Must have one | Pe-PhI approaches 0, at which time lg | Pe-PhI tends to be minus infinity, so after summation
Approaching plus infinity, which means that the heat value of the second electronic device c in the first target device set H approaches plus infinity, that is, the corresponding heat value is higher. When the distance between a 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 exceeds 10 kilometers, that is, the distance is greater
All of | P ine-PhAll are greater than 10, i.e.
All of (1) (-lg | P)e-Ph|) are negative values, in which case the sum is then
A negative value indicates that the second electronic device f is lower in heat. Based on this, by the formula
After the heat value of each second electronic device is calculated, the heat level 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 event that the at least two different job tasks include a first job task and a second job task, allocating a fixed-size first space in a first target resource space to the second job task;

The first job task is a job task in which the usage rate of the target resource space is smaller than a first preset value in a first preset time period, and may refer to: the usage rate of the storage resources of the first job task in the past month is lower than 50%, and the usage rate of the broadband resources is also lower than 50%. The second job task is a job task in which the utilization rates of the target resource spaces in the first preset time period are all greater than or equal to a first preset value, and the utilization rates of the target resource spaces in the first preset time period continuously increase, and may refer to: the utilization rate of the storage resources of the second job task in the past month is higher than 50%, the utilization rate of the broadband resources is also higher than 50%, the utilization rate of the storage resources in each day is higher than that of the storage resources in the previous day, and the utilization rate of the broadband resources in each day is also higher than that of the broadband resources in the previous day.
The usage rate 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 rate of the storage resource may be calculated every thirty minutes, and then the average of the usage rates of the storage resource for one day is obtained, so as to obtain the usage rate of the storage resource for the day. Similarly, the calculation process of the usage rates of the storage resources of the other job tasks except the first job task may also be calculated according to the above method. In addition, the calculation process of the utilization rate of the broadband resource can also be calculated according to the method.
The first space may be 10% of the first target resource space.
In the embodiment, second target electronic devices which run at least two job tasks simultaneously are determined, then the utilization rate of the target resource space of each job task in each second target electronic device is monitored, and the space of a first job task with low utilization rate of the target resource space is transferred to a second job task with high utilization rate of the target resource space and increasing utilization rate of the target resource space. Therefore, the space occupied by each job task in the second target electronic equipment under the dynamic condition is realized. And each job task is ensured to normally run on the second target electronic equipment, and the utilization rate of resources is improved.
