The CDN central control is a core part of a distribution synchronization system, externally receives video and static resource distribution tasks of a plurality of business departments, such as an upper business system and the like, and is matched with an accurate scheduling system to ensure a first-class viewing experience when a user accesses a master station and various Application programs (APP).

The large number of distribution tasks not only robs the source bandwidth with the user, but also influences the user experience. The distribution process is carried out in the peak stage of the user access, which causes the bandwidth resource to be robbed by the distribution process and the user access process, and the access to the user can be influenced, thus influencing the user experience.

In addition, resources delivered to CDN nodes during peak periods may not be accessed in time by users, such as when the occupancy bandwidth is used to deliver resources that will be of interest in the future, and existing approaches may also be understood as unnecessary delivery during peak periods, which may increase bandwidth costs. The embodiment of the invention can fully utilize bandwidth resources in non-peak stages, such as idle resources in early morning and other periods, and non-urgent tasks, and can also understand that the non-urgent distribution tasks can be delayed to the idle stages for distribution, such as delayed to early morning, so that unnecessary distribution tasks can be avoided in late peak stages, the idle resources are fully utilized, and the bandwidth cost can be reduced.
The task distribution control method provided by the embodiment of the invention is described in detail below with reference to specific embodiments.
The control method for task distribution provided by the embodiment of the invention can be applied to a synchronous distribution system, and particularly can be applied to distribution central control.
An embodiment of the present invention provides a method for controlling task distribution, as shown in fig. 1, may include:
s101, obtaining emergency degree information of tasks to be distributed; the emergency degree information includes: the upper limit of the distribution bandwidth corresponding to the task to be distributed, the service type corresponding to the task to be distributed or the influence degree of any corresponding resource to be distributed on the user access;
S102, matching the emergency degree information with preset emergency task information;

and S104, when the emergency degree information is matched with the emergency task information, taking the task to be distributed as an emergency task, and controlling the real-time distribution of the task to be executed.
In the embodiment of the invention, the real-time distribution can be performed for the urgent task and the delay distribution can be performed for the non-urgent task, so that the distribution can be performed only for the urgent task in the peak stage, the non-urgent task can be delayed to the idle stage except the peak stage, the competing of bandwidth resources between the distribution process and the user access process can be reduced, and the influence of the distribution process on the user access is reduced.
Referring to fig. 1, a detailed description is given of a method for controlling task distribution according to an embodiment of the present invention.
S101, emergency degree information of tasks to be distributed is obtained.
The urgency information may include information indicating the urgency of the task to be distributed, and may be understood as indicating whether the task to be distributed is an urgent task or a non-urgent task. The emergency degree information may include: the upper limit of the distribution bandwidth corresponding to the task to be distributed, the service type corresponding to the task to be distributed or the influence degree of any corresponding resource to be distributed on the access of the user.
S102, matching the emergency degree information with preset emergency task information.
The preset urgent task information may include preset conditions (e.g., threshold) corresponding to a preset distribution bandwidth upper limit, preset conditions (e.g., threshold) corresponding to a service type or a degree of influence on user access, and so on.
The method can analyze the characteristics of the emergency task in the actual application in advance, and can also be understood as analyzing the characteristics of the task which needs to be distributed in real time in the actual application process, and taking the characteristics as preset emergency task information.
For example, the service type belonging to the urgent task in the actual application process is analyzed. Or analyzing the influence of the resource of the emergency task in the actual application process for the user access, quantifying the influence to obtain the corresponding influence degree, and counting the influence degree corresponding to the emergency task in the actual application process to obtain the threshold value of the influence degree for the user access. Or, different distribution bandwidth upper limits can be allocated to different service channels, preset conditions corresponding to the distribution bandwidth upper limits can be obtained according to actual application statistics, and the like.
And obtaining the emergency degree information of the task to be distributed, and matching the emergency degree information of the task to be distributed with the preset emergency task information.
In one embodiment, the urgent degree information of the task to be distributed may be compared with the preset urgent task information, and if the preset urgent task information includes the urgent degree information of the task to be distributed, the urgent degree information is matched with the urgent task information, the task to be distributed may be used as an urgent task; and if the preset urgent task information does not contain urgent degree information of the task to be distributed, indicating that the urgent degree information is not matched with the urgent task information, taking the task to be distributed as a non-urgent task.
For example, the urgency information of the task to be distributed may include a traffic type of the task to be distributed. Comparing the service type of the task to be distributed with the service type included in preset emergency task information; if the preset urgent task information includes a service type of the task to be distributed, determining that urgent degree information of the task to be distributed is matched with preset urgent task information, and when the urgent degree information is matched with the preset urgent task information, the task to be distributed can be used as an urgent task. If the service type of the task to be distributed is not included in the preset urgent task information, judging that the urgent degree information of the task to be distributed is not matched with the preset urgent task information, and if the urgent degree information of the task to be distributed is not matched with the preset urgent task information, taking the task to be distributed as a non-urgent task.
In another embodiment, it may be determined whether the emergency degree information of the task to be distributed satisfies a preset condition, such as a threshold, included in the preset emergency task information. If the preset condition is met, the emergency degree information representing the task to be distributed is matched with the emergency task information, and the task to be distributed can be used as an emergency task; and if the preset condition is not met, the emergency degree information is not matched with the emergency task information, and the task to be distributed is taken as a non-emergency task.
For example, the degree of impact may be understood as a parameter that affects access of resources in a task to a user. The influence of the resources in different tasks on the user access can be expressed by different influence degrees, and the influence degrees are positively correlated with the influence of the resources on the user access. The preset emergency task information may include a preset influence degree parameter threshold. If the emergency degree corresponding to the task to be distributed is not less than the influence degree parameter threshold, the emergency degree information of the task to be distributed is matched with the emergency task information, and the task to be distributed can be used as an emergency task; and if the emergency degree corresponding to the task to be distributed is smaller than the influence degree parameter threshold value, indicating that the emergency degree information is not matched with the emergency task information, taking the task to be distributed as a non-emergency task.
In another embodiment, the current available bandwidth corresponding to the current time may be determined based on the upper limit of the distribution bandwidth corresponding to the task to be distributed and the bandwidth required by the task to be distributed; judging whether the current available bandwidth meets a preset condition, and if the current available bandwidth meets the preset condition, the emergency degree information of the task to be distributed is matched with the emergency task information, and the task to be distributed can be used as an emergency task; and if the preset condition is not met, the emergency degree information is not matched with the emergency task information, and the task to be distributed is taken as a non-emergency task.
S103, when the emergency degree information is not matched with the emergency task information, taking the task to be distributed as a non-emergency task, and controlling the task to be distributed in a delayed manner;
the resources corresponding to the non-urgent tasks do not affect the current access of the user. That is, the task to be distributed is also understood as a resource distributed for the task to be distributed, and the user cannot access the resource in the current access process.
In particular, controlling the delayed distribution of the task to be distributed may include caching the task to be distributed at a current time and distributing the task to be distributed at a subsequent time. In one implementation, the current time is in a late peak stage, such as 18 to 23 points, and the time period containing idle bandwidth resources can be delayed to the early morning and the like to distribute the tasks to be distributed.
In one implementation, in order to ensure timely completion of resource distribution, for example, the resource distribution is completed within 24 hours after the resource is generated, the use condition of bandwidth can be detected in real time after the resource is generated, and the task to be distributed is controlled to be distributed in a delayed manner and the resource distribution can be performed as soon as possible.
And S104, when the emergency degree information is matched with the emergency task information, taking the task to be distributed as an emergency task, and controlling the real-time distribution of the task to be executed.
Wherein, the resources corresponding to the urgent task can influence the access of the user.
In an alternative embodiment, when the task to be distributed is an urgent task and the resource corresponding to the task to be distributed affects the access of the user, if the resource distributed for the task to be distributed is the resource accessed by the user in the current access process, the task to be distributed can be controlled to be distributed in real time.
In an alternative embodiment, during the process of distributing for emergency tasks, the distribution may be performed at different distribution rates according to the service requirements.
In the embodiment of the invention, the real-time distribution can be performed for the urgent task and the delay distribution can be performed for the non-urgent task, so that the distribution can be performed only for the urgent task in the peak stage, the non-urgent task can be delayed to the idle stage except the peak stage, the competing of bandwidth resources between the distribution process and the user access process can be reduced, and the influence of the distribution process on the user access is reduced. And further, the user experience can be improved.
Meanwhile, the non-urgent tasks are delayed to idle phases except the peak phase, for example, the non-urgent distribution tasks can be delayed to the non-peak phase to perform distribution, for example, the non-urgent distribution tasks are delayed to the early morning distribution, the idle phases can be fully utilized, bandwidth resources of the non-peak phases can be understood, for example, idle resources in the early morning and other periods can be avoided, unnecessary distribution tasks can be prevented from being performed in the late peak phase, the idle resources can be fully utilized, and the bandwidth cost can be reduced. In this way, both reduced bandwidth costs and improved user viewing experience can be achieved.
And bandwidth resources in a peak stage are used for distributing aiming at urgent tasks, and bandwidth resources in an idle stage are utilized for distributing aiming at non-urgent tasks, so that reasonable utilization of bandwidth resources can be realized, precious bandwidth resources are used for distributing important tasks and watching by users as much as possible, and the distribution capacity is improved.
In an alternative embodiment, as shown in fig. 2, S101: obtaining emergency information of tasks to be distributed may include:
s201, obtaining a distribution bandwidth upper limit corresponding to a task to be distributed.
The upper limit of the distribution bandwidth represents the maximum value of the available bandwidth of the service channel corresponding to the task to be distributed; the upper distribution bandwidth limit is positively correlated with the urgency of the traffic channel.
The upper limit of the distribution bandwidth corresponding to each service channel is positively correlated with the emergency degree of the service channel. The more urgent a traffic channel is, the greater the upper limit of the distribution bandwidth corresponding to the traffic channel is. The total bandwidth is limited, each service channel occupies a corresponding bandwidth according to its degree of urgency (in one way, it can be understood as the degree of importance), and the sum of the upper limits of the service bandwidths corresponding to each service channel does not exceed an upper limit at all times, in one implementation, the upper limit is 150Gbps.
The distribution bandwidth upper limit corresponding to each service channel may include a distribution bandwidth upper limit corresponding to the service channel in different time ranges.
After S201, it may further include:
s202, determining the current available bandwidth corresponding to the current time based on the upper limit of the distribution bandwidth corresponding to the task to be distributed and the bandwidth required by the task to be distributed.
Specifically, the bandwidth required by the task to be distributed may be subtracted from the upper limit of the distribution bandwidth corresponding to the current time, and the obtained difference is used as the current available bandwidth.
And S203, when the current available bandwidth does not meet the preset condition, caching the task to be distributed until the available bandwidth corresponding to the subsequent time meets the preset condition, and controlling the task to be distributed in the subsequent time.
It can be understood that S103: when the urgent degree information does not match with the urgent task information, then taking the task to be distributed as a non-urgent task, and controlling the task to be distributed to be delayed and distributed may include: when the current available bandwidth does not meet the preset condition, the task to be distributed is cached until the available bandwidth corresponding to the subsequent time meets the preset condition, and the task to be distributed is controlled to be distributed in the subsequent time.
Wherein the subsequent time is a time after the current time.
And S204, when the current available bandwidth meets the preset condition, controlling to distribute the task to be distributed at the current time.
It can be understood that S104: when the emergency degree information is matched with the emergency task information, taking the task to be distributed as the emergency task, and controlling the real-time distribution of the task to be executed can comprise: when the current available bandwidth meets the preset condition, the task to be distributed is controlled to be distributed at the current time.
Specifically, when the current available bandwidth is not greater than zero, caching the task to be distributed until the available bandwidth corresponding to the subsequent time is greater than zero, and controlling the task to be distributed; when the current available bandwidth is greater than zero, the task to be distributed is controlled to be distributed.
The current available bandwidth is a dynamically changing value, and in one implementation, when the task to be distributed is distributed, the resource size corresponding to the task to be distributed can be subtracted, and meanwhile, the distribution bandwidth upper limit value corresponding to the time is increased every second. If the current available bandwidth is less than 0, indicating that no spare bandwidth is available for distribution at the moment, the tasks to be distributed need to be cached, and the delayed tasks to be distributed have an opportunity to be distributed until the subsequent continuous accumulation (the added value per second is the preset upper limit of the distribution bandwidth) is greater than 0. Thus, when the available bandwidth corresponding to the current time period is greater than 0, the task to be distributed can be distributed, and meanwhile, the bandwidth required by the task to be distributed is subtracted from the current available bandwidth, such as the size of the resource corresponding to the task to be distributed. When the current available bandwidth is smaller than or equal to 0, the task to be distributed is controlled to be cached until the available bandwidth in the subsequent time range is accumulated to the total of the available bandwidths in the current time range to be larger than 0, and the task to be distributed is controlled to be distributed.
Thus, delay distribution through bandwidth precise control can be realized.
In an alternative embodiment, as shown in fig. 3, S201 may include:
S2011, a target service channel corresponding to the task to be distributed is obtained.
The traffic channels may be divided according to different traffic types.
And S2012, obtaining bandwidth configuration information.
The bandwidth configuration information comprises distribution bandwidth upper limits corresponding to the plurality of service channels in a plurality of time ranges.
In one implementation, the value of the upper distribution bandwidth limit may become larger as the degree of urgency increases, i.e., the higher the upper distribution bandwidth limit corresponding to the more urgent traffic channel.
The bandwidth configuration information is pre-configured and stored, and the synchronous distribution system can directly acquire the bandwidth configuration information.
A synchronous distribution system in one implementation may include a bandwidth control module through which bandwidth configuration information is periodically obtained.
S2013, analyzing the bandwidth configuration information to obtain a target distribution bandwidth upper limit corresponding to the target service channel, and taking the target distribution bandwidth upper limit as a distribution bandwidth upper limit corresponding to the task to be distributed.
In one implementation, to achieve control of the distribution rate during the distribution, S204: when the current available bandwidth meets the preset condition, controlling to distribute the task to be distributed at the current time, as shown in fig. 4, may include:
S2041, obtaining a target service channel corresponding to the task to be distributed.
S2042, obtaining rate configuration information, wherein the rate configuration information comprises distribution rates corresponding to a plurality of service channels; analyzing the rate configuration information to obtain a target distribution rate corresponding to the target service channel; and controlling the task to be distributed according to the target distribution rate.
The distribution rate can be understood as the number of tasks distributed per second.
The rate configuration information can be preconfigured and stored, and the synchronous distribution system can directly acquire the rate configuration information.
Thus, bandwidth configuration information and rate configuration information can be combined, and more accurate task distribution can be realized.
In a specific embodiment, as shown in fig. 5, the distribution center control in the synchronous distribution system may include a bandwidth control module and a rate control module. The distribution central control receives tasks through an external interface, and the tasks can comprise task 1 and task 2 and … …. After receiving the task, judging whether the bandwidth is abundant or not through the bandwidth control module, and judging whether the current available bandwidth meets the preset condition or not and is larger than 0 or not; if the bandwidth is insufficient, if the current available bandwidth is not more than 0, the task is cached, if the bandwidth is insufficient, if the current available bandwidth is more than 0, whether overspeed is distributed is judged through a speed control module, if overspeed is not, the distribution speed can be adjusted, and if overspeed is not, the task is processed, namely the task is distributed.
For example, the sum of the available traffic of the initial stage traffic channel in the time period [ a, b ] is total 1 ＝bandwidth 1 X (b-a), wherein, bandwidth 1 The upper limit of the distribution bandwidth for the time period (a, b) is that the service channel distribution task firstly passes through a bandwidth control module, total 1 >When 0, the task is forwarded to the rate control module for processing, and total is simultaneously carried out 1 Subtracting the task size, when total 1 <At 0, the task is cached until total in the next time interval [ b, c ] 2 ＝total 1 / +bandwidth 2 ×(c-b)>0, at which time the task does not continue to be processed by the rate control module, where bandwidth 2 As the upper limit of the distribution bandwidth of the time period [ b, c ], otherwise, continuing to buffer until the subsequent bandwidth is rich for distributing tasks, wherein total 1 / Is total 1 Subtracting the task size. The rate control module strictly controls the task distribution rate in the time interval, namely the task number distributed per second, for example, k, and k can be determined according to the actual service requirement.
And the distribution task consumes a preset bandwidth upper limit, and decides a follow-up distribution action according to the balance of the bandwidth, and if the balance is insufficient, the task is cached until the bandwidth is sufficient. Delay distribution is realized through bandwidth precise control, so that bandwidth competing of the distribution and the source returning caused by user access is avoided, the influence of the distribution process on the user access is reduced, the user experience is improved, bandwidth resources are reasonably utilized, and the distribution capacity is improved; and meanwhile, the idle bandwidth in the early morning is fully utilized, and the bandwidth cost is reduced.

and obtaining bandwidth configuration information corresponding to CDN nodes of the content delivery network.

And unnecessary distribution in the peak stage can be avoided, idle resources in the off-peak stage are fully utilized, and the bandwidth cost is reduced.
When the distribution synchronization system uniformly controls all CDN nodes through the distribution central control, the distribution rate and the bandwidth control can exert an effect on all CDN nodes, and if more strict bandwidth control is required to be carried out on part of special nodes, a strategy can be specially customized through the cloud control module, and the cloud control mode can be understood to be realized. And the control strategy is synchronized to a specific CDN node by the distribution central control, and the CDN node independently completes the accurate control of the distribution rate and the bandwidth. The bandwidth control logic of the cloud control module is the same as the logic controlled by the distribution central control, but the distribution central control is completed by the CDN node itself, and is responsible for periodically acquiring the pre-configured bandwidth configuration information, wherein the bandwidth configuration information can be a cloud control configuration table, analyzes the strategy and synchronizes to the corresponding node. Therefore, a stricter control strategy can be formulated for the individual nodes, and the control mode is more flexible.
