Fig. 3 is a flowchart illustrating another method for processing a lower rate according to an exemplary embodiment, where as shown in fig. 3, the interaction subject of the disclosed embodiment is at least one terminal, a traffic scheduling server, and a plurality of resource servers, and the method includes:

301. the target resource server obtains a first sending rate requested by the traffic scheduling server in a first time period.

The embodiment of the disclosure is applied to a scheduling system, and the scheduling system comprises a flow scheduling server and a plurality of resource servers. The target resource server may be any resource server in the scheduling system.

The sending rate is the proportion of the resource link of the target resource server in the resource links sent by the traffic scheduling server to the at least one terminal. For each time segment, the target resource server can determine the sending rate in the time segment, send the sending rate to the traffic scheduling server, and request the traffic scheduling server to send the resource link of the target resource server according to the sending rate in the time segment.

The target resource server sets at least two time periods according to a fixed period, and the time span of each time period is equal to the fixed period. The target resource server can determine the sending rate of the next time period according to the traffic generation condition of the previous time period each time, thereby realizing the periodic setting of the sending rate. The fixed period may be set according to a requirement of the target resource server for updating the delivery rate, and may be, for example, 1 second, 1 minute, or 1 hour.

Optionally, at the starting time of each time period, the target resource server determines the delivery rate in the time period, and sends the delivery rate to the traffic scheduling server. And at the starting time of the next time period, the target resource server determines the issuing rate in the next time period again and sends the issuing rate to the traffic scheduling server.

And when the sending rate is determined each time, the target resource server stores the sending rate in the database, and when the sending rate of the previous time period needs to be used in the next time period, the sending rate of the previous time period is directly called from the database of the target resource server.

In the embodiment of the present disclosure, a first time period and a second time period are taken as an example, and a process of determining an issue rate in the second time period according to the first time period is described, where the first time period may be any time period, the second time period is a next time period of the first time period, and processes of determining issue rates in other time periods are similar to the embodiment of the present disclosure, and are not described in detail herein.

The sending rate in the first time period determined by the target resource server is called a first sending rate, and the sending rate in the second time period determined by the target resource server is called a second sending rate. The first delivery rate may be obtained by the target resource server according to the delivery rate in the previous time period of the first time period, and the obtaining manner is similar to the process of obtaining the second delivery rate according to the first delivery rate in the subsequent step, which is not described here for the moment. Or, the target resource server provides service for the first time in a first time period, where the first time period is an initial time period of the target resource server, and the first delivery rate is determined as a preset delivery rate, where the preset delivery rate may be a delivery rate randomly determined by the target resource server, or a delivery rate determined according to a lower flow limit of the target resource server, and the like.

302. The target resource server obtains a first flow in a first time period.

The first traffic is generated by at least one terminal accessing a resource link of a target resource server for a first time period.

Optionally, in a first time period, each time a target resource server receives an access request sent by any terminal, a resource corresponding to a resource link is obtained according to the resource link carried by the access request and sent to the terminal, and a generated flow is counted in the process of sending the resource, and the flow is recorded, so that a total flow in the first time period can be counted as a first flow. And the target resource server stores the counted first flow so as to facilitate subsequent calling.

303. And the target resource server acquires the target flow in the second time period.

The target flow is determined by the target resource server according to the flow required to be generated in the second time period, and may be set by a maintenance person of the target resource server, or may be calculated by the target resource server.

Optionally, the target resource server configures a bandwidth resource, where a traffic that can be supported by an upper limit of the bandwidth resource is the upper limit of the traffic of the target resource server, but in an actual operation process of the target resource server, in order to ensure stable service, an achieved traffic is smaller than the upper limit of the traffic. Therefore, the traffic that is achieved on the premise that the target resource server ensures that the service is stable can be determined as the target traffic.

For example, the bandwidth resource of the target resource server is 100 million, and the target resource server can provide stable service when the traffic does not exceed 90 million, then the target traffic of the target resource server is 90 million.

It should be noted that, in each time period, the target traffic set by the target resource server may be the same or different. For example, the target resource server may set the same target traffic for most of the time period, and when an abnormal condition occurs in a certain time period, the target traffic may be adjusted according to the requirement.

304. And the target resource server determines a second issuing rate requested by the traffic scheduling server in a second time period according to the ratio of the first issuing rate to the first traffic and the target traffic.

In the embodiment of the disclosure, in the same time period, after the target resource server requests the traffic scheduling server for the delivery rate, the traffic scheduling server delivers the resource link according to the delivery rate, so as to generate traffic on the target resource server. Therefore, there is an association relationship between the issued rate and the traffic.

However, since the target resource server cannot know the total number of the resource links issued by the traffic scheduling server in each time period in advance, and cannot predict when the terminal accesses the resource links after acquiring the resource links, it is not possible to accurately determine what kind of association relationship exists between the issuing rate and the traffic.

Considering that the association relationship between the delivery rate and the traffic in different time periods is the same, the association relationship between the delivery rate and the traffic in the first time period may be adopted to estimate the association relationship between the delivery rate and the traffic in the second time period.

Therefore, the target resource server obtains the proportion between the first sending rate and the first flow rate, the incidence relation between the sending rate and the flow rate in the first time period is expressed by the proportion, and the target resource server already determines the target flow rate in the second time period, so that the second sending rate in the second time period can be determined according to the proportion between the first sending rate and the first flow rate and the target flow rate.

Optionally, the step 304 may include any one of the following steps 3041 and 3043:

3041. according to the proportion between the first issuing rate and the first flow and the target flow, determining a second issuing rate requested to the flow scheduling server in a second time period by adopting the following formula:

The reason why the second delivery rate is determined by the above formula is that:

assuming that the total number of resource links issued by a traffic scheduling server is m, the issuing rate of a target resource server is r, a conversion coefficient is lambda, the conversion coefficient represents the proportion of the resource links accessed by the terminal in the resource links of the target resource server received by the terminal, lambda belonging to (0.06-0.15) can be obtained through multiple tests, the number of the resource links of the target resource server actually accessed by the terminal is n, the traffic generated by the resource links accessed by the terminal to the target resource server is b, and the traffic coefficient is beta, the traffic coefficient represents the proportion of the accessed one resource link to the actually generated traffic, and beta belonging to (3-8) can be obtained through multiple tests.

Then the following relationship holds:

n＝m×r×λ；

b＝n×β；

comparing the second time period with the first time period, assuming that the total number m of the resource links issued by the traffic scheduling server is unchanged, therefore, the following association relationship can be obtained:

b ₁ ＝m×r ₁ ×λ×β；

b ₂ ＝m×r ₂ ×λ×β；

namely:

3042. according to the proportion between the first issuing rate and the first flow and the target flow, determining a second issuing rate requested to the flow scheduling server in a second time period by adopting the following formula:

Considering that there is delay in the process of accessing the resource link by the terminal after the traffic scheduling server issues the resource link of the target resource server according to the issue rate in a certain time period. That is, during the time period some resource links are accessed, resulting in traffic on the target resource server, but some resource links are temporarily not accessed, resulting in traffic on the target resource server, and during the time period after the time period, once these resource links are accessed, traffic can still be generated on the target resource server. Then, only according to the ratio between the first delivery rate and the first flow rate, the correlation between the delivery rate and the flow rate cannot be accurately reflected, and the influence of the time delay needs to be considered.

Therefore, the preset duration is introduced in the step 3042, and the preset duration can be determined by counting the time intervals between the issuing time and the accessing time of a large number of resource links, and the issuing rates are uniformly distributed in the preset duration, so as to implement dynamic adjustment of the traffic.

For example, the time span of each time period is 1 minute, the terminal receives 10 resource links issued by the traffic scheduling server in the first time period, and only 1 resource link is accessed in the first time period, and the traffic actually generated by the target resource server is only the traffic generated by accessing the 1 resource link. And, the user's access to these 10 resource links takes a total of 7 minutes, spanning 7 time periods, with the resulting traffic being spread over these 7 time periods.

For another example, the experimental data shows that, for the issued resource link, about 50% of the traffic is effective within 3 minutes after the issue, and about more than 95% of the traffic is effective within 7 minutes.

3043. When the first flow exceeds the preset flow upper limit, determining a second issuing rate requested to the flow scheduling server in a second time period by adopting the following formula according to the proportion between the first issuing rate and the first flow and the target flow:

a ₁ ＝r ₁ ×10％；

wherein r is ₁ Is the first incidence, r ₂ Is the second issue rate, b ₁ Is a first flow rate, b ₂ Is a target flow rate, a ₁ To suppress the first delivery rate, a ₂ Avg (a) is another delivery rate obtained by suppressing the first delivery rate ₁ +a ₂ ) Is a ₁ And a ₂ Rho is a preset inhibiting factor, t is a preset duration, and the preset duration is a time interval between the time when the traffic scheduling server issues any resource link and the time when any resource link is accessed.

The preset flow upper limit is the maximum flow which can be reached by the target resource server on the premise of ensuring the service stability, when the flow of the target resource server is smaller than the preset flow upper limit, the target resource server can provide stable service, and when the flow of the target resource server is larger than the preset flow upper limit, the issuing rate of the target resource server needs to be effectively controlled, so that the flow generated by the target resource server in the next time period is smaller than the preset flow upper limit.

In addition, the target resource server may further set a preset lower flow limit, which may be set according to a minimum flow when the bandwidth resource of the target resource server is effectively utilized.

When the flow of the target resource server exceeds the preset flow upper limit, the issuing rate is restrained by adopting the formula, wherein a is obtained by multiplying the first issuing rate by 10 percent ₁ The first issue rate is suppressed, therefore, a ₁ The method can generate a strong inhibition effect on the delivery rate to realize strong inhibition on the delivery rate obtained after the first delivery rate is inhibited. And multiplying the issuing rate obtained by the first issuing rate, the first flow and the target flow by a preset inhibition factor rho to obtain a ₂ The first incidence is suppressed in another way, so that a ₂ In order to obtain another delivery rate after the first delivery rate is inhibited, a weak inhibition effect can be generated on the delivery rate, weak inhibition is realized, and the delivery rate after strong inhibition and weak inhibition is comprehensively considered to obtain a second delivery rate.

Optionally, it is detected whether the flow rate in each time period exceeds the preset flow rate upper limit, and when the flow rates in the consecutive preset number of time periods exceed the preset flow rate upper limit, the manner of step 3043 is adopted to suppress the delivery rate. When the flow rate within the continuous preset number of time periods is not detected to exceed the preset flow rate upper limit, the step 3043 is not performed, but the delivery rate is determined in a manner. Therefore, the method can ensure that the sending rate is inhibited only when the continuous bandwidth is out of range, avoid inhibiting the sending rate when the temporary bandwidth is out of range and reduce the influence of the temporary bandwidth to the minimum.

It should be noted that the steps 3041 and 3043 are optional steps, and may or may not be executed. In addition, the target resource server may also acquire the second delivery rate in other manners, and the specific manner for acquiring the second delivery rate is not limited in the embodiment of the present disclosure.

305. And the target resource server sends the second sending rate to the traffic scheduling server.

And after the second sending rate is obtained, the target resource server sends the second sending rate to the traffic scheduling server to request the traffic scheduling server to send the resource link of the target resource server according to the second sending rate.

It should be noted that, the above-mentioned steps 301-305 may be executed at the starting time of the second time period, or may also be executed at a time corresponding to a preset time length before the starting time of the second time period, where the preset time length is less than the time span of the time period, and may be, for example, 0.01 second, 0.1 second, and the like.

306. And the traffic scheduling server issues the resource link of the target resource server to at least one terminal according to the second issuing rate.

And the traffic scheduling server receives a second sending rate sent by the target resource server, performs traffic scheduling according to the second sending rate, and sends the resource link to at least one terminal, wherein the proportion of the resource link of the target resource server in the sent resource link is the second sending rate.

For a specific process of the traffic scheduling server issuing the resource link, please refer to the embodiment shown in fig. 4 below.

307. When at least one terminal detects the trigger operation of the resource link of the target resource server, the terminal sends a resource request carrying the resource link to the target resource server.

The terminal displays the resource link after receiving the resource link issued by the traffic scheduling server, the user can perform triggering operation on the resource link, and the terminal sends a resource request carrying the resource link to a target resource server when detecting the triggering operation.

The trigger operation may be a click operation, a slide operation, or the like.

Optionally, the target resource server stores one or more resources, sets a resource identifier of each resource, and can distinguish different resources according to the resource identifier.

And after receiving the resource request, the target resource server acquires the resource corresponding to the resource identifier according to the resource identifier included in the resource link in the resource request, sends the resource to the terminal and displays the resource by the terminal. In addition, the resource sending process also generates flow on the target resource server, and the target resource server can count the flow generated in the resource sending process.

It should be noted that, in the embodiment of the present disclosure, the target resource server in the scheduling system is merely taken as an example to describe the process of determining the delivery rate, and the target resource server may be any resource server in the multiple resource servers. The process of determining the sending rate by other resource servers is similar to the embodiment of the present disclosure, and is not described in detail herein.

In the related art, a scheduling system includes a scheduling server and a plurality of resource servers connected to the scheduling server, a terminal sends a resource request to the scheduling server, when receiving the resource request, the scheduling server selects a target resource server from the plurality of resource servers by using a global load balancing scheduling method, sends an IP (Internet Protocol) address of the target resource server to the terminal, the terminal sends the resource request to the target resource server according to the IP address, and acquires a resource from the target resource server, where the resource acquisition process generates traffic on the target resource server. However, the method is suitable for constructing a large-scale scheduling system, the requirement on the resource server is high, and the resource server needs to prepare enough bandwidth resources in advance. However, if the traffic actually generated by the resource server does not reach the upper limit of the bandwidth resource of the resource server, the bandwidth resource is wasted, and the utilization rate of the bandwidth resource is not high.

In the method provided by the embodiment of the disclosure, a target resource server obtains a first sending rate requested by a target resource server in a first time period, obtains a first flow generated when at least one terminal accesses a resource link of the target resource server in the first time period, obtains a target flow in a second time period, determines a second sending rate requested by the target resource server in the second time period according to the ratio of the first sending rate to the first flow and the target flow, sends the second sending rate to the target resource server, and sends the resource link of the target resource server by the target resource server according to the second sending rate. The method can determine the issuing rate of the request to the traffic scheduling server in the next time period according to the issuing rate of the request to the traffic scheduling server in the previous time period, the traffic actually generated in the previous time period and the target traffic required to be generated in the next time period, changes the passive mode into the active mode, can prejudge the traffic condition of the next time period on the premise of ensuring the service stability, realizes the control of the traffic of the next time period, avoids the problem of traffic overflow and improves the sensitivity of traffic sensing. And the control of bandwidth resources is realized by adjusting the flow, excessive bandwidth resources do not need to be prepared for preventing the high flow, the waste of the bandwidth resources is avoided, and the utilization rate of the bandwidth resources is improved.

In addition, a scheme for performing traffic scheduling through a Domain Name System (DNS) server is also proposed in the related art, in which a terminal sends a Domain Name resolution request to the DNS server, the DNS server selects an IP address of a resource server from a plurality of IP addresses corresponding to a Domain Name according to a load balancing policy based on the Domain Name provided by the terminal, and sends the IP address to the terminal, and the terminal accesses resources provided by the resource server according to the IP address of the resource server. However, this method needs to pass through the DNS server of the operator, and is greatly influenced by the operator. The method provided by the embodiment of the disclosure can bypass the DNS, avoids the influence caused by the DNS, and directly acts on the terminal, thereby realizing accurate flow control and improving the utilization rate of equipment.

The traffic scheduling is performed by adopting a conventional manner in the related art and the method provided by the embodiment of the present disclosure, and the scheduling results are obtained as follows:

when traffic is scheduled in a conventional manner in the related art, a traffic curve generated by a resource server in each time period is as shown in fig. 4, an abscissa represents time, and an ordinate represents a ratio of generated traffic, the traffic curve generates higher traffic in a part of the time period and lower traffic in a part of the time period, in order to enable the resource server to provide stable service also in the time period with higher traffic, sufficient bandwidth resources need to be prepared, and the utilization rate of the bandwidth resources in the time period with lower traffic is low, which causes waste of bandwidth resources.

When the method provided by the embodiment of the present disclosure is used to schedule traffic, a curve of the requested delivery rate of the resource server in each time period is shown in fig. 5, an abscissa represents time, an ordinate represents delivered resource proportion, and a curve of traffic generated by the resource server in each time period is shown in fig. 6. The resource server is provided with 32% of bandwidth resources, and the upper limit of the bandwidth is controlled to 31% in order to provide a stable service.

Comparing fig. 5 and fig. 6, when the traffic generated by the resource server is high, a lower delivery rate is determined in the next time period, and the traffic generated by the resource server is reduced by reducing the delivery rate. When the flow generated by the resource server is lower, a higher issuing rate is determined in the next time period, and the flow generated by the resource server is increased by increasing the issuing rate. The control method can keep the stable fluctuation of the flow, control the flow below the upper limit of the bandwidth, avoid preparing excessive bandwidth resources and improve the bandwidth utilization rate.

Fig. 7 is a flowchart illustrating a traffic scheduling method according to an exemplary embodiment, where as shown in fig. 7, the interaction subject of the disclosed embodiment is at least one terminal, a traffic scheduling server, and a plurality of resource servers, and the method includes:

701. and the resource servers send the sending rate to the traffic scheduling server.

In each time period, the resource servers send the determined sending rates to the traffic scheduling server, and the sending rates of different resource servers can be the same or different.

702. And the traffic scheduling server receives the sending rates sent by the plurality of resource servers.

703. And the traffic scheduling server stores the issuing rates of the plurality of resource servers.

Optionally, each resource server has corresponding address information, and the traffic scheduling server may store the delivery rate of each resource server in the database in correspondence with the address information, so as to distinguish the delivery rates of different resource servers.

Optionally, after receiving the multiple delivery rates sent by the multiple resource servers, the traffic scheduling server sums the multiple delivery rates. And when the sum of the multiple sending rates is equal to 100%, the traffic scheduling server stores the received sending rates of the multiple resource servers, and sends the resource links of the multiple resource servers respectively according to the stored sending rates of the multiple resource servers in the next time period before receiving the sending rates sent by the multiple resource servers in the next time period.

When the sum of the multiple delivery rates is not equal to 100%, the traffic scheduling server obtains a proportional relation among the multiple delivery rates, and recalculates the delivery rates of the multiple resource servers according to the proportional relation, so that the recalculated sum of the multiple delivery rates is equal to 100%. And returning each recalculated delivery rate to the corresponding resource server, wherein each resource server replaces the previously stored delivery rate with the delivery rate returned by the flow scheduling server, the flow scheduling server stores the recalculated delivery rates of the plurality of resource servers, and the resource links of the plurality of resource servers are respectively delivered according to the stored delivery rates of the plurality of resource servers before receiving the delivery rates sent by the plurality of resource servers in the next time period.

For example, in a time period, three resource servers send down rates to the traffic scheduling server, where the down rate sent by each resource server is shown in table 1:

TABLE 1

Resource server	Delivery rate
		Resource server 1	40％
Resource server 2	30％
		Resource server 3	50％

The sum of the delivery rates of the three resource servers is 120%, and at this time, the traffic scheduling server recalculates the new delivery rates according to the proportional relationship among the delivery rates of the three resource servers, as shown in table 2:

TABLE 2

Resource server	Delivery rate
		Resource server 1	33.3％
Resource server 2	25％
		Resource server 3	41.7％

The traffic scheduling server sends the recalculated delivery rate to the corresponding resource server, and each resource server replaces the previously stored delivery rate with the delivery rate sent by the traffic scheduling server, for example, the resource server 1 replaces the original 40% with 33.3%.

704. And the traffic scheduling server selects one resource server according to the issuing rates of the plurality of resource servers and issues the resource link of the selected resource server to at least one terminal.

Optionally, this step 704 may include steps 7041 or 7042:

7041. when a resource request sent by any terminal is received, one resource server is selected according to the issuing rate of the multiple resource server requests, and the resource link corresponding to the resource request on the selected resource server is issued to the terminal.

In each time period, in the process of issuing the resource link, the traffic scheduling server counts the proportion of the resource links of the plurality of resource servers in the resource link issued in the time period, that is, the issuing rate of the plurality of resource servers in the time period. When the traffic scheduling server receives a resource request sent by any terminal, the traffic scheduling server obtains the difference between the sending rate requested by each resource server and the sending rate that has been reached, selects any resource server with the difference larger than 0 from a plurality of resource services, and sends the resource link corresponding to the resource request on the selected resource server to the terminal, or selects the resource server with the largest difference, and sends the resource link corresponding to the resource request on the selected resource server to the terminal.

The traffic scheduling server may store a resource link provided by each resource server, where the resource link includes a resource identifier. And the resource request sent by the terminal carries the resource identifier to be requested, so that the traffic scheduling server acquires the resource link provided by the resource server, including the resource identifier, after selecting the resource server, and sends the resource link to the terminal.

7042. And issuing the resource links of the resource servers to at least one terminal according to the issuing rate of the request of the resource servers.

The traffic scheduling server may recommend a resource link for the at least one terminal according to a recommendation policy.

Taking the traffic scheduling server to recommend resources for a certain terminal as an example, in each time period, the traffic scheduling server may count the respective proportions of the resource links of the plurality of resource servers in the resource links that have been delivered in the time period, that is, the delivery rates that have been achieved by the plurality of resource servers in the time period. The traffic scheduling server can compare the delivery rates which have been reached by the resource servers, select the resource server corresponding to the minimum delivery rate, and deliver the resource link on the resource server to the terminal; or the resource link of the corresponding proportion on each resource server can be issued to the terminal according to the reciprocal of the proportional relation among the issued rates which have been reached by the plurality of resource servers.

Or acquiring the difference between the request issuing rate of each resource server and the achieved issuing rate, selecting any resource server with the difference larger than 0 from the plurality of resource services, and issuing the resource link on the selected resource server to the terminal, or selecting the resource server with the largest difference and issuing the resource link on the selected resource server to the terminal.

The traffic scheduling server may store the resource links provided by each resource server, and may select the resource links provided by a resource server according to a recommendation policy each time the resource link of a certain resource server is issued.

According to the method provided by the embodiment of the disclosure, the traffic scheduling server can issue the resource links of the resource servers according to the issuing rates requested by the resource servers, and the resource servers can determine the issuing rate to be requested to the traffic scheduling server in the next time period according to the issuing rate requested to the traffic scheduling server in the previous time period, the actually generated traffic in the previous time period and the target traffic required to be generated in the next time period, and can prejudge the traffic condition in the next time period, thereby realizing the control of the traffic in the next time period and avoiding the problem of traffic overflow. And excessive bandwidth resources do not need to be prepared, so that the waste of the bandwidth resources is avoided, and the utilization rate of the bandwidth resources is improved.
