Figure 1 is a schematic flowchart of a scheduling method provided by an exemplary embodiment of the present application. The method may include the steps shown in Figure 1:

Step 101: Determine the access request of the terminal, which is used to access the target server through the cloud desktop; the cloud desktop is connected to the terminal through the first line among the single lines of multiple operators.

Step 102: Determine a second line from the single lines of the multiple operators according to the bandwidth equalization strategy; the bandwidth equalization strategy is used to equalize the uplink and downlink bandwidth peaks of the operators.

The embodiments of this application are applicable to cloud desktop service systems. The cloud desktop service system includes a server and a gateway. The server can be a conventional physical server or an elastic server (virtual machine), which is not limited in this embodiment. The gateway can be a physical gateway or a virtual gateway. Among them, the server runs a cloud desktop application (hereinafter referred to as cloud desktop) and a scheduler. Among them, the cloud desktop can provide the same services as the terminal's local desktop, including but not limited to: office services based on the cloud desktop and services for accessing the external Internet. Among them, the scheduler is used to schedule the cloud desktop access request to the line connected to the gateway, and the gateway sends it through the line.

In this embodiment, the cloud desktop service system may include at least an ingress gateway and an egress gateway. Among them, the ingress gateway is used to realize network interconnection with user-side terminals (such as the user's mobile phone, computer, smart wearable device); the egress gateway is used to realize network interconnection with the external Internet. In this embodiment, the ingress gateway and egress gateway can connect single lines of multiple operators. A single-wire line is a line for data transmission based on a single-wire bandwidth. Single-line bandwidth is the type of bandwidth provided by each operator. The transmission line of the single-line bandwidth provided by any operator must be realized through the lines within the operator's backbone network.

Among them, the bandwidth used on any operator's single line includes: the bandwidth used in the ingress direction and the bandwidth used in the egress direction. For the cloud desktop service system, the entrance direction refers to the access direction of the terminal, and the exit direction refers to the direction of outward access to the Internet. The entrance bandwidth of any operator refers to the bandwidth used to transmit data between the terminal and the cloud desktop service system in the entrance direction through the single line provided by the operator, including the downlink bandwidth used by the terminal to send data to the cloud desktop service system. , and the upstream bandwidth used by the desktop service system to send data to the terminal. The egress bandwidth of any operator refers to the bandwidth used to transmit data between the cloud desktop service system and the external Internet in the egress direction through the lines provided by the operator, including the uplink bandwidth used by the cloud desktop service system to send data to the external Internet. bandwidth, and the downlink bandwidth used by the external Internet to send data to the cloud desktop service system. That is, for the cloud desktop service system, the uplink bandwidth used includes: the total uplink bandwidth in the ingress direction and the egress direction; the downlink bandwidth used includes: the total downlink bandwidth in the ingress direction and egress direction. Among them, the downlink bandwidth in the ingress direction is mainly used to transmit user requests, and the bandwidth consumption is small; the uplink bandwidth in the ingress direction is mainly used to transmit video streams with the cloud desktop, and the bandwidth consumption is large. The uplink bandwidth in the egress direction is mainly used to transmit network access requests, and the bandwidth consumption is small; the downlink bandwidth in the egress direction is mainly used to receive network data returned from the external Internet, and the bandwidth consumption is large.

In some scenarios, when settling fees for single-line bandwidth services provided by operators, the peak method is usually used, that is, fees are settled based on the peak value of bandwidth used within a set time range. For example, the peak method may be the 95 peak method. In the 95 peak method, the effective bandwidth within the period is obtained according to a certain period, and the obtained effective bandwidth is arranged in descending order. After arranging, the top 5% of the effective bandwidths are removed, and the bandwidth peak (that is, the 95th bandwidth peak) is selected from the remaining 95% of the effective bandwidth for bandwidth billing. That is, for a single operator, the higher the 95 bandwidth peak value, the greater the bandwidth cost. Wherein, when there is an uplink bandwidth and a downlink bandwidth, the bandwidth peak value used for fee settlement can be determined based on the larger of the 95 bandwidth peak value in the uplink direction and the 95 bandwidth peak value in the downlink direction. That is, the closer the bandwidth utilization in the upstream direction and the downstream direction is, the smaller the difference between the 95% bandwidth peak value in the upstream direction and the 95% bandwidth peak value in the downlink direction, and the more fully the bandwidth cost is utilized. Among them, the line in the entrance direction is selected by the terminal, and usually the terminal can choose the single-line line of the operator corresponding to the network where it is located. For example, if the network used by the terminal is the network of the first operator, the terminal can use the line provided by the first operator to access the cloud desktop. That is, the bandwidth in the ingress direction is not scheduled by the cloud desktop service system. Based on this, when accessing the external Internet through the cloud desktop, the operator's line in the egress direction can be scheduled so that the peak uplink bandwidth and the peak downlink bandwidth of a single operator are more consistent, thereby improving bandwidth utilization and reducing bandwidth overall. cost. The cloud desktop service system can establish a connection with the terminal through any single line of multiple operators' single lines connected to the entrance gateway. For ease of description and distinction, the single line used between the cloud desktop service system and the terminal is described as the first line. The cloud desktop service system can receive the cloud desktop access request sent by the terminal through the first line, and the cloud desktop service system can return the desktop image to the terminal through the first line for the user to view.

In some optional embodiments, for the terminal, the first line may be a single line of the operator where the network service used by the terminal is located. Optionally, before receiving the access request sent by the terminal through the first line, the cloud desktop service system may obtain the operator information corresponding to the network used by the terminal, determine the first line that matches the operator information, and use the third line to obtain the access request sent by the terminal through the first line. A line's access point address is provided to the terminal. In this implementation, optionally, a client program corresponding to the cloud desktop service system can be run on the terminal. The client program can obtain operator information corresponding to the network used by the terminal upon authorization from the terminal. , and sends the operator information to the cloud desktop server.

In some other optional embodiments, for the terminal, the first line may also be a single-line line with better quality selected by the terminal from single-line lines of multiple operators. Optionally, before receiving the access request sent by the terminal through the first line, the cloud desktop service system may also provide multiple access point addresses corresponding to the single lines of the multiple operators to the terminal. Furthermore, the terminal may send quality detection data to the multiple access point addresses and select the first line from the single lines of the multiple operators according to the quality detection results.

In some cases, the cloud desktop needs to access the target server in the public network. This requirement can be triggered by an end user's operation or by an application running on the cloud desktop, which is not limited in this embodiment. The cloud desktop service system may determine an access request for accessing the target server through the cloud desktop, and may issue the access request to the target server through the egress gateway. In this embodiment, when the cloud desktop service system accesses the target server through the cloud desktop, it can schedule the operator's single line in the egress direction to select a single line from multiple operators' single lines and pass the selected single line to access the target server. Among them, the selected single-line line can be marked as the second line.

Based on the above records, it can be seen that the downlink bandwidth in the ingress direction and the uplink bandwidth in the egress direction have little impact on the bandwidth settlement method based on the peak method, and the two can reach a balance to a certain extent. Therefore, the downlink bandwidth in the ingress direction and the uplink bandwidth in the egress direction may not be considered in bandwidth scheduling. Among them, the uplink bandwidth in the ingress direction and the downlink bandwidth in the egress direction have a greater impact on the bandwidth settlement method based on the peak method. Therefore, when the uplink bandwidth in the ingress direction is not scheduled, when scheduling the operator's lines in the egress direction, narrowing the gap between the downlink bandwidth in the egress direction and the uplink bandwidth in the ingress direction can be the scheduling goal. On this basis, the strategy adopted for scheduling the operator's single line in the egress direction may be a bandwidth balancing strategy. Among them, the bandwidth balancing strategy is used to balance the operator's uplink and downlink bandwidth peaks, that is, to make the operator's downlink bandwidth peaks and uplink bandwidth peaks reach a balance to a certain extent. Based on the foregoing, it can be seen that when the downlink bandwidth in the ingress direction and the uplink bandwidth in the egress direction are small, the bandwidth balancing strategy involved in each embodiment of the present application is mainly used to balance the operator's downlink bandwidth in the egress direction and the uplink bandwidth in the ingress direction. No further details will be given later.

Based on this, when accessing the target cloud desktop service system in the Internet through the egress direction, a bandwidth balancing strategy can be used to schedule access requests to the target cloud desktop service system, thereby controlling the egress bandwidth peaks of different operators, so that different operators can The downlink bandwidth peak value is closer to the uplink bandwidth peak value to reduce the probability that a single operator will cause a larger 95 peak value due to a larger downlink bandwidth peak value in the egress direction.

In this implementation, the cloud desktop service system is connected to single lines of multiple operators. On the one hand, the cost of cloud desktop services can be reduced based on the low cost of single lines; on the other hand, it can be based on single lines of multiple operators. Provide high-quality cloud desktop access services to users of different operators, making cloud desktop services more cost-effective and smooth. When accessing the target server through the cloud desktop, single-line lines of multiple operators are scheduled according to the bandwidth balancing policy. The peak uplink bandwidth and downlink bandwidth peak of a single operator can be balanced to improve the utilization of existing downlink bandwidth resources. This enables "peak-shaving and valley-filling" of egress bandwidth consumption among different operators, further reducing overall bandwidth costs.

The bandwidth balancing strategy provided by the embodiments of the present application will be further exemplified below with reference to specific embodiments.

In some optional embodiments A1, the bandwidth balancing strategy may include: operator-consistent strategies for ingress lines and egress lines. This policy is used to make the operator connected to any cloud desktop in the ingress direction consistent with the operator connected in the egress direction. When the first line of the cloud desktop service system is connected to the terminal and receives the terminal's access request through the first line, the first line is the entrance line.

In this embodiment, when determining the second line from the single-line lines of multiple operators, the first operator to which the first line belongs can be determined, and the single-line line belonging to the first line can be selected from the single-line lines of the multiple operators. The single line of the first carrier acts as the second line. Wherein, the second line is an exit line. The cloud desktop service system may send an access request to the target server through the second line, so that the target server returns the request data through the second line.

In this implementation, the operator distribution of the egress lines can be adjusted according to the operator distribution of the ingress lines. This effectively reduces the probability that ingress and egress bandwidth is concentrated on some operator lines, while egress bandwidth is concentrated on another part of operator lines. According to the operator of the single-line bandwidth connected to the cloud desktop in the ingress direction, specifying the operator in the egress direction of the cloud desktop can make the scheduling times of any operator's ingress lines more consistent with the usage times of the ingress lines, thus balancing the The operator's bandwidth usage in the ingress direction and egress direction, thereby balancing the operator's peak uplink bandwidth and peak downlink bandwidth. Furthermore, when bandwidth settlement is performed based on the larger value of the downlink bandwidth peak value and the uplink bandwidth peak value, the bandwidth cost can be fully utilized.

In some optional embodiments A2, the bandwidth equalization strategy includes: the operator's uplink and downlink bandwidth peak consistency strategy. For any operator, the higher the consistency of its upstream and downstream bandwidth peaks, the higher the bandwidth utilization.

Based on this, in some optional embodiments, the available downlink bandwidth of single-line lines of multiple operators can be obtained. The available amount of downlink bandwidth of any single-line line is used to describe the existing bandwidth of the single-line line in the downlink direction. available for use. Among them, the existing bandwidth in the downstream direction can be determined according to the bandwidth settlement principle. In some embodiments, according to the bandwidth settlement principle, the peak bandwidth of any single-line line is determined by the larger of the peak downstream bandwidth and the peak uplink bandwidth of the single-line line. Furthermore, on the premise that the peak uplink bandwidth is known, The available downstream bandwidth can be determined. If the peak uplink bandwidth of a single line is higher, the available downlink bandwidth is higher. If the peak uplink bandwidth is low, the available downlink bandwidth is low. For example, if the peak bandwidth of a certain operator's single-line line in the upstream direction is 50M, then the available bandwidth in the downstream direction can be 50M. When the peak bandwidth in the downstream direction is less than or equal to 50M, fees can be settled based on the peak bandwidth of 50M. When the bandwidth of about 50M is fully used in the downlink direction, the benefits of bandwidth costs can be maximized.

Based on this, according to the available downlink bandwidth of the single-line lines of multiple operators, the scheduling hit probability of the single-line lines of multiple operators in the egress direction can be determined. Among them, the scheduling hit probability of any single-line line is used to describe the possibility of scheduling the single-line line for data transmission.

Among them, the lower the operator's available downlink bandwidth, the closer the operator's bandwidth utilization in the uplink and downlink directions is, and the lower the scheduling hit probability in the egress direction. The higher the operator's available downlink bandwidth, the greater the difference in the operator's bandwidth utilization in the uplink and downlink directions. In order to improve the operator's bandwidth utilization in the downlink direction, the scheduling hit probability of the operator's single line in the egress direction can be increased.

Optionally, after determining the available downlink bandwidth of the single-line lines of multiple operators, the available downlink bandwidth of the single-line lines of multiple operators can be determined according to the positive correlation between the available amount of downlink bandwidth and the scheduling hit probability. The scheduling hit probability of single lines of multiple operators. That is, the greater the available downlink bandwidth of a certain single-line line, the higher the scheduling hit probability of the single-line line in the egress direction.

When an access request needs to be sent to the target server, the second line may be determined from the single-line lines of the multiple operators based on the scheduling hit probabilities of the single-line lines of the multiple operators in the egress direction.

The following will take any operator as an example to illustrate the method of obtaining the available downlink bandwidth. Optionally, for any operator's single line, the peak uplink bandwidth in the ingress direction and the peak downlink bandwidth in the egress direction of the single line can be obtained. Among them, the bandwidth fee can be settled according to the settlement cycle, which can be 12 hours, 24 hours, one week or one month. After entering any settlement cycle, the bandwidth peaks in different directions can be counted according to the set frequency, and egress line scheduling can be performed in real time based on the statistically obtained bandwidth peaks. Among them, the peak uplink bandwidth in the ingress direction and the peak downlink bandwidth in the egress direction are the peak bandwidth usage statistics in the current settlement period. The difference between the upstream and downstream bandwidth peak values of the single-wire line is determined based on the peak upstream bandwidth of the single-wire line in the ingress direction and the peak downstream bandwidth in the egress direction. The available downlink bandwidth of the single-line line is determined based on the difference between the peak values of the uplink and downlink bandwidths of the single-line line. The greater the difference between the upstream and downstream bandwidth peaks of a single-line line, the higher the available downlink bandwidth of the single-line line. On the contrary, the smaller the difference between the upstream and downstream bandwidth peaks of a single-line line, the lower the available downlink bandwidth of the single-line line. In some embodiments, the difference between the peak values of the uplink and downlink bandwidths may be used as the available downlink bandwidth of the single-wire line.

When the available downlink bandwidth of a single-line line is high, more access requests can be scheduled to the single-line line, thereby making full use of the existing bandwidth resources under fixed cost; at the same time, it can help reduce the bandwidth usage of other lines. , thereby reducing the probability of increased costs for other lines.

For example, in some scenarios, when the operators to which users in the ingress direction belong are unevenly distributed, different operators have unequal amounts of spare resources in the egress direction. For example, among the users of the cloud desktop, there are more users belonging to the first operator and fewer users belonging to the second operator. Therefore, the first operator consumes more uplink bandwidth in the entrance direction, and the second operator consumes more uplink bandwidth. Less upstream bandwidth is consumed in the ingress direction. According to the charging principle of the peak method described in the foregoing embodiments, it can be seen that the first operator has more available spare bandwidth resources in the downlink direction, and the second operator has less available spare bandwidth resources in the downlink direction. Therefore, when egress link scheduling is performed, more requests in the egress direction can be scheduled to the line of the first operator, and fewer requests in the egress direction can be scheduled to the line of the second operator, thus Make full use of spare bandwidth resources in the egress direction.

Further exemplary description will be given below with reference to Figure 2 .

The cloud desktop service system can provide public cloud desktop services. As shown in Figure 2, the server of the cloud desktop service system can run the cloud desktop of tenant 1, the cloud desktop of tenant 2, and the cloud desktop of tenant 3. The cloud desktop service system connects single lines of multiple operators and is used to connect the backbone network of the first operator, the backbone network of the second operator and the backbone network of the third operator respectively.

The cloud desktop can receive the access request forwarded by the scheduling layer and send the access request to the target server through the scheduling layer. Data transmission between the scheduling layer and external devices includes data transmission in the uplink direction and data transmission in the downlink direction. Assume that the home network used by Tenant 1 is provided by the first operator. When Tenant 1 accesses the cloud desktop, the scheduling layer can receive the access request sent by Tenant 1 through the first operator's backbone network and send the access request to Tenant 1. cloud desktop. The cloud desktop can return the desktop image through the first operator's backbone network for tenant 1 to view. When the cloud desktop accesses the public network server under the user's operation, the scheduling layer can schedule the cloud desktop access request according to the bandwidth balancing policy.

For example, the scheduling layer may send an access request to the public network server through the first operator's single line, so that the public network server returns response data through the first operator's single line. In this way, the uplink bandwidth generated by the cloud desktop sending desktop images to tenant 1 and the downlink bandwidth generated by the cloud desktop receiving the response data returned by the public network server are balanced to a certain extent.

For another example, the scheduling layer may determine the available downlink bandwidth of the single-line bandwidth provided by the first operator, the second operator, and the third operator. Assume that the available downlink bandwidth of the first operator is 5M, the available downlink bandwidth of the second operator is 30M, and the available downlink bandwidth of the single-line bandwidth provided by the third operator is 50M, then the scheduling layer can pass the third operator The third operator's single-line line sends an access request to the public network server, so that the public network server returns response data through the third operator's single-line line. Furthermore, the existing bandwidth of the third operator can be fully utilized, and the bandwidth of the third operator in the downlink direction can be used to supplement the bandwidth of the first operator in the downlink direction. Bandwidth sharing can be formed in the egress direction, reducing the cost of the first operator. The bandwidth peak in the downstream direction is larger, which may increase the cost.

It is worth noting that after determining the scheduling hit probabilities of the single-line lines of the multiple operators in the egress direction, the visited target server operator can be further determined, hereinafter referred to as the second operator. The second operator belongs to multiple operators that the egress gateway is connected to. When determining the second line from the single-line lines of the multiple operators based on the scheduling hit probabilities of the single-line lines of the multiple operators in the egress direction, the second line may be determined based on the scheduling hit probabilities of the single-line lines of the multiple operators, Determine whether the scheduling hit probability of the single-line line of the second operator satisfies the set condition; if yes, use the single-line line of the second operator as the second line. The setting conditions may include: the scheduling hit probability is greater than a certain probability threshold, or the scheduling hit probability is among the top N in the order from high to low, where N is a positive integer. After determining the second line based on the bandwidth balancing policy, the access request can be sent to the target server through the second line, and the target server can return the request data through the second line.
