[0023] In response to the technical problem in the prior art that providing shadowless cloud desktop services based on BGP bandwidth has a high price cost, a solution is provided in some embodiments of the present application. The technical solutions provided in each embodiment of the present application are described in detail below in conjunction with the accompanying drawings.

[0024] Figure 1 is a flowchart of a scheduling method provided by an exemplary embodiment of the present application, which may include: Figure 1 Steps shown:

[0025] Step 101: Determine an access request from a terminal, where the access request is for accessing a target server through a cloud desktop; the cloud desktop is connected to the terminal through a first line among single-line lines of multiple operators.

[0026] Step 102: Determine a second line from the single-line lines of the multiple operators according to a bandwidth balancing strategy; the bandwidth balancing strategy is used to balance the upstream and downstream bandwidth peaks of the operators.

[0027] Step 103: Send an access request to the target server through the second line, so that the target server returns the requested data through the second line.

[0028] The embodiment of the present application is applicable to a cloud desktop service system. 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. A cloud desktop application (hereinafter referred to as a cloud desktop) and a scheduler are running on the server. The cloud desktop can provide the same services as the local desktop of the terminal, including but not limited to: office services based on the cloud desktop and services for accessing the external Internet. The scheduler is used to schedule the access request of the cloud desktop to the line connected to the gateway, and the gateway sends it through the line.

[0029] In this embodiment, the cloud desktop service system may include at least an entry gateway and an exit gateway. Among them, the entry gateway is used to achieve network interconnection with the terminal on the user side (such as the user's mobile phone, computer, smart wearable device); the exit gateway is used to achieve network interconnection with the external Internet. In this embodiment, the entry gateway and the exit gateway can connect to the single-line lines of multiple operators. A single-line line is a line for data transmission based on single-line bandwidth. Single-line bandwidth is a bandwidth type provided by each operator. The transmission line of single-line bandwidth provided by any operator must be implemented through the line within the backbone network of the operator.

[0030] The bandwidth used on any operator's single-line line includes the bandwidth used in the ingress direction and the bandwidth used in the egress direction. For the cloud desktop service system, the ingress direction refers to the terminal's access direction, and the egress direction refers to the direction of outbound access to the internet. The ingress bandwidth of any operator refers to the bandwidth used for data transmission between the terminal and the cloud desktop service system via the single-line line provided by that operator in the ingress direction. This includes the downlink bandwidth used by the terminal to send data to the cloud desktop service system, and the uplink bandwidth used by the desktop service system to send data to the terminal. The egress bandwidth of any operator refers to the bandwidth used for data transmission between the cloud desktop service system and the external internet via the line provided by that operator in the egress direction. This includes the uplink bandwidth used by the cloud desktop service system to send data to the external internet, and the downlink bandwidth used by the external internet to send data to the cloud desktop service system. Specifically, for the cloud desktop service system, its uplink bandwidth includes the total uplink bandwidth in the ingress and egress directions, and its downlink bandwidth includes the total downlink bandwidth in the ingress and egress directions. The downlink bandwidth in the ingress direction is primarily used to transmit user requests, resulting in lower bandwidth consumption. The uplink bandwidth in the ingress direction is primarily used to transmit video streams with the cloud desktop, resulting in higher bandwidth consumption. The upstream bandwidth in the egress direction is mainly used to transmit network access requests, and the bandwidth consumption is relatively small; the downstream bandwidth in the egress direction is mainly used to receive network data returned from the external Internet, and the bandwidth consumption is relatively large.

[0031] In some scenarios, a peak method is often used when settling fees for single-line bandwidth services provided by operators. This method uses the peak bandwidth usage within a set timeframe for billing. For example, this peak method can be the 95% peak method. In this method, the effective bandwidth for a specific period is obtained and sorted in descending order. After sorting, the top 5% of the effective bandwidth is removed, and the peak bandwidth (i.e., the 95% peak bandwidth) is selected from the remaining 95% for bandwidth billing. That is, for a single operator, the higher the 95% peak bandwidth, the higher the bandwidth fee. When both upstream and downstream bandwidth are available, the peak bandwidth used for billing can be determined based on the larger of the 95% peak bandwidth in the upstream direction and the 95% peak bandwidth in the downstream direction. The closer the bandwidth utilization in the upstream and downstream directions, the smaller the difference between the 95% peak bandwidth in the upstream and downstream directions, and the more efficient the bandwidth cost utilization. The ingress line is selected by the terminal, which typically chooses the single-line line of the operator corresponding to its network. 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 subject to the scheduling of the cloud desktop service system. Based on this, when accessing the external Internet through the cloud desktop, the operator line in the egress direction can be scheduled so that the uplink bandwidth peak and the downlink bandwidth peak of a single operator are more consistent, so as to improve bandwidth utilization and reduce bandwidth costs as a whole. The cloud desktop service system can establish a connection with the terminal through any single-line line of multiple operators connected to the ingress gateway. For the sake of ease of description and distinction, the single-line line used between the cloud desktop service system and the terminal is described as the first line. The cloud desktop service system can receive a 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.

[0032] In some optional embodiments, for the terminal, the first line may be a single-line line of the operator of the network service used by the terminal. Optionally, before receiving the access request sent by the terminal via 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 provide the access point address of the first line to the terminal. In this embodiment, optionally, a client program corresponding to the cloud desktop service system may be running on the terminal. The client program may, with the authorization of the terminal, obtain the operator information corresponding to the network used by the terminal and send the operator information to the cloud desktop server.

[0033] In other optional embodiments, for the terminal, the first line may also be a single-line line with better quality selected by the terminal from among multiple operators' single-line lines. Optionally, before receiving an access request sent by the terminal via the first line, the cloud desktop service system may also provide the terminal with multiple access point addresses corresponding to the multiple operators' single-line lines. Furthermore, the terminal may send quality detection data to the multiple access point addresses and select the first line from among the multiple operators' single-line lines based on the quality detection results.

[0034] In some cases, the cloud desktop has a need to access a target server in the public network. This need can be triggered by the operation of the terminal user or by the application running on the cloud desktop, which is not limited in this embodiment. The cloud desktop service system can determine the access request for accessing the target server through the cloud desktop, and can send the access request to the target server through the egress gateway. In this embodiment, when accessing the target server through the cloud desktop, the cloud desktop service system can schedule the operator's single-line line in the egress direction to select a single-line line from multiple operators' single-line lines, and access the target server through the selected single-line line. Among them, the selected single-line line can be marked as the second line.

[0035] Based on the foregoing, it can be seen that the ingress downstream bandwidth and the egress upstream bandwidth have little impact on the peak-based bandwidth settlement method, and the two can be balanced to a certain extent. Therefore, the ingress downstream bandwidth and the egress upstream bandwidth can be excluded from consideration for bandwidth scheduling. However, the ingress upstream bandwidth and the egress downstream bandwidth have a greater impact on the peak-based bandwidth settlement method. Therefore, when scheduling the operator's line in the egress direction, if the ingress upstream bandwidth is not scheduled, the scheduling goal can be to reduce the gap between the egress downstream bandwidth and the ingress upstream bandwidth. Based on this, the strategy adopted for scheduling the operator's single line in the egress direction can be a bandwidth balancing strategy. The bandwidth balancing strategy is used to balance the operator's peak upstream and downstream bandwidths, that is, to achieve a certain balance between the operator's peak downstream and peak upstream bandwidths. Based on the foregoing, it can be seen that when the ingress downstream bandwidth and the egress upstream bandwidth are relatively small, the bandwidth balancing strategy involved in the various embodiments of this application is primarily used to balance the operator's downstream bandwidth in the egress direction and the upstream bandwidth in the ingress direction, and will not be further described.

[0036] Based on this, when accessing the target cloud desktop service system on 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, making the downlink bandwidth peaks of different operators closer to the uplink bandwidth peaks, thereby reducing the probability that a single operator will have a larger 95% peak due to a larger downlink bandwidth peak in the egress direction.

[0037] In this implementation, the cloud desktop service system is connected to single lines from multiple operators. This reduces the cost of cloud desktop services based on the low cost of single lines, and provides high-quality cloud desktop access services to users of different operators based on these single lines, making cloud desktop services more cost-effective and smoother. When accessing a target server through a cloud desktop, the single lines from multiple operators are scheduled according to a bandwidth balancing strategy. This can improve the utilization of existing downlink bandwidth resources by balancing the peak uplink and downlink bandwidth of a single operator, thereby achieving "peak shaving" of outbound bandwidth consumption between different operators and further reducing overall bandwidth costs.

[0038] The bandwidth balancing strategy provided in the embodiments of the present application will be further illustrated below with reference to specific embodiments.

[0039] In some optional embodiments A1, the bandwidth balancing strategy may include: a policy for aligning the ingress and egress providers. This strategy ensures that the provider connected to any cloud desktop in the ingress direction is consistent with the provider connected to the egress direction. When a first line of the cloud desktop service system is connected to a terminal and receives an access request from the terminal via the first line, the first line is the ingress line.

[0040] In this embodiment, when determining the second line from multiple single-line circuits operated by different operators, the first operator to which the first line belongs can be determined, and a single-line circuit operated by the first operator can be selected from the multiple single-line circuits operated by the multiple operators as the second line. The second line is an egress line. The cloud desktop service system can send an access request to the target server via the second line, so that the target server returns the requested data via the second line.

[0041] In this embodiment, the operator distribution of the export line can be adjusted according to the operator distribution of the ingress line. Thus, the probability of the ingress and egress bandwidth being concentrated on a part of the operator lines and the egress bandwidth being concentrated on another part of the operator lines is effectively reduced. According to the operator to which the single-line bandwidth connected in the ingress direction of the cloud desktop belongs, the operator of the cloud desktop in the egress direction is specified, so that the number of scheduling times of the ingress line of any operator is more consistent with the number of times the ingress line is used, and thus the bandwidth usage of the operator in the ingress direction and the egress direction can be balanced, thereby balancing the upstream bandwidth peak and the downstream bandwidth peak of the operator. Furthermore, when bandwidth settlement is performed according to the larger value of the downstream bandwidth peak and the upstream bandwidth peak, the bandwidth cost can be fully utilized.

[0042] In some optional embodiments A2, the bandwidth balancing strategy includes: an operator's uplink and downlink bandwidth peak consistency strategy. For any operator, the higher the consistency of its uplink and downlink bandwidth peaks, the higher the bandwidth utilization.

[0043] Based on this, in some optional embodiments, the available downstream bandwidth of single-line links from multiple operators can be obtained. The available downstream bandwidth of any single-line link describes the available bandwidth in the downstream direction of that single-line link. The available downstream bandwidth can be determined according to bandwidth settlement principles. In some embodiments, according to bandwidth settlement principles, the peak bandwidth of any single-line link is determined by the larger of the peak downstream bandwidth and the peak upstream bandwidth of that single-line link. Furthermore, given the known peak upstream bandwidth, the available downstream bandwidth can be determined. If the peak upstream bandwidth of a single-line link is higher, the available downstream bandwidth is higher. If the peak upstream bandwidth is lower, the available downstream bandwidth is lower. For example, if the peak upstream bandwidth of a single-line link from a certain operator is 50 Mbps, the available downstream bandwidth can be 50 Mbps. If the peak downstream bandwidth is less than or equal to 50 Mbps, billing can be based on the peak bandwidth of 50 Mbps. When approximately 50 Mbps of bandwidth is fully utilized in the downstream direction, the benefits of bandwidth costs can be maximized.

[0044] Based on this, the scheduling hit probability of the multiple operators' single-line links in the egress direction can be determined based on the available downlink bandwidth of the multiple operators' single-line links. The scheduling hit probability of any single-line link is used to describe the possibility of scheduling the single-line link for data transmission.

[0045] The lower the operator's available downlink bandwidth, the closer the uplink and downlink bandwidth utilization rates are for that operator, and the lower the scheduling hit probability in the egress direction. The higher the operator's available downlink bandwidth, the greater the difference in bandwidth utilization rates between the uplink and downlink directions. To improve the operator's downlink bandwidth utilization, the scheduling hit probability of the operator's single-line in the egress direction can be increased.

[0046] Optionally, after determining the available downlink bandwidth of multiple operators' single-line links, the scheduling hit probability of the multiple operators' single-line links can be determined based on the available downlink bandwidth of the multiple operators' single-line links, based on the positive correlation between available downlink bandwidth and scheduling hit probability. That is, the greater the available downlink bandwidth of a single-line link, the higher the scheduling hit probability of the single-line link in the egress direction.

[0047] When an access request needs to be sent to a target server, a second line may be determined from the single-line lines of the multiple operators according to the scheduling hit probability of the single-line lines of the multiple operators in the egress direction.

[0048] The following uses any operator as an example to illustrate how to obtain 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 can be obtained. Bandwidth fees can be settled according to a settlement cycle, which can be 12 hours, 24 hours, a week, or a month. After entering any settlement cycle, bandwidth peaks in different directions can be counted at a set frequency, and egress line scheduling can be performed in real time based on the resulting peak bandwidths. The peak uplink bandwidth in the ingress direction and the peak downlink bandwidth in the egress direction represent the peak bandwidth usage counted during the current settlement cycle. Based on the peak uplink bandwidth in the ingress direction and the peak downlink bandwidth in the egress direction of the single-line, the difference between the peak uplink and downlink bandwidths of the single-line is determined. Based on the difference between the peak uplink and downlink bandwidths of the single-line, the available downlink bandwidth of the single-line is determined. The greater the difference between the peak uplink and downlink bandwidths of the single-line, the higher the available downlink bandwidth of the single-line. Conversely, the smaller the difference between the uplink and downlink bandwidth peaks of a single line, the lower the available downlink bandwidth of the single line. In some embodiments, the difference between the uplink and downlink bandwidth peaks can be used as the available downlink bandwidth of the single line.

[0049] When the available downlink bandwidth of a single line is high, more access requests can be scheduled to the single line, thereby fully utilizing the existing bandwidth resources at a fixed cost. At the same time, it can help reduce the bandwidth usage of other lines, thereby reducing the probability of cost increases on other lines.

[0050] 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 idle resources in the egress direction. For example, among the users of the cloud desktop, the number of users belonging to the first operator is relatively large, and the number of users belonging to the second operator is relatively small. Therefore, the first operator consumes more uplink bandwidth in the ingress direction, and the second operator consumes less uplink bandwidth in the ingress direction. According to the peak method billing principle described in the aforementioned embodiment, the first operator has more available idle bandwidth resources in the downlink direction, and the second operator has fewer available idle bandwidth resources in the downlink direction. Therefore, when performing egress link scheduling, 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, thereby making full use of the idle bandwidth resources in the egress direction.

[0051] The following will be combined Figure 2 Further exemplary description is given.

[0052] The cloud desktop service system can provide public cloud desktop services, such as Figure 2 As shown, the cloud desktop service system server 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 is connected to a single line of multiple operators, which is used to connect to the backbone network of the first operator, the backbone network of the second operator, and the backbone network of the third operator respectively.

[0053] The cloud desktop receives access requests forwarded by the scheduling layer and sends them to the target server through the scheduling layer. Data transmission between the scheduling layer and external devices includes both upstream and downstream data transmission. Assuming that the home network used by tenant 1 is provided by the first operator, when tenant 1 accesses the cloud desktop, the scheduling layer receives the access request sent by tenant 1 through the first operator's backbone network and sends the access request to tenant 1's cloud desktop. The cloud desktop returns 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 user operation, the scheduling layer schedules the cloud desktop's access request based on the bandwidth balancing policy.

[0054] For example, the scheduling layer can send an access request to the public network server via the first operator's single-line line, so that the public network server returns response data via the first operator's single-line line. This ensures that the uplink bandwidth generated by the cloud desktop sending the desktop image 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.

[0055] For another example, the scheduling layer can determine the available downlink bandwidth of the single-line bandwidth provided by the first operator, the second operator, and the third operator. Assuming 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, the scheduling layer can send an access request to the public network server through the single-line line of the third operator, so that the public network server returns response data through the single-line line of the third operator. 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, forming bandwidth sharing in the export direction, reducing the possibility of increased costs for the first operator due to the large peak bandwidth in the downlink direction.

[0056] It is worth noting that after determining the scheduling hit probability of the single-line lines of the multiple operators in the export direction, the operator of the target server to be accessed can be further determined, hereinafter referred to as the second operator. The second operator belongs to the multiple operators connected to the export gateway. When determining the second line from the single-line lines of the multiple operators based on the scheduling hit probability of the single-line lines of the multiple operators in the export direction, it can be judged based on the scheduling hit probability of the single-line lines of the multiple operators whether the scheduling hit probability of the single-line line of the second operator meets the set conditions; if so, the single-line line of the second operator is used as the second line. Among them, the set conditions may include: the scheduling hit probability is greater than a certain probability threshold, or the scheduling hit probability is in the top N in the order from high to bottom, N is a positive integer. After the second line is determined based on the bandwidth balancing strategy, an access request can be sent to the target server through the second line, and the target server can return the requested data through the second line.

[0067] Optionally, after determining the scheduling hit probability of the single-line lines of the multiple operators in the egress direction based on the available downlink bandwidth of the single-line lines of the multiple operators, the processor 302 is further used to: determine the second operator where the target server is located; the second operator belongs to the multiple operators; determine the second line from the single-line lines of the multiple operators based on the scheduling hit probability of the single-line lines of the multiple operators in the egress direction, including: judging whether the scheduling hit probability of the single-line line of the second operator meets the set conditions based on the scheduling hit probability of the single-line lines of the multiple operators; if yes, using the single-line line of the second operator as the second line.

[0070] Further, if Figure 3 As shown, the server also includes: a power supply component 304 and other components. Figure 3 Only some components are shown schematically, which does not mean that the server only includes Figure 3 Components shown.

[0071] Among them, the memory 301 can be implemented by any type of volatile or non-volatile storage device or a combination thereof, such as static random-access memory (SRAM), electrically erasable programmable read-only memory (EEPROM), erasable programmable read-only memory (EPROM), programmable read-only memory (PROM), read-only memory (ROM), magnetic memory, flash memory, magnetic disk or optical disk.

[0072] The communication component 303 is configured to facilitate wired or wireless communication between the device where the communication component is located and other devices. The device where the communication component is located can access a wireless network based on a communication standard, such as Wi-Fi (wireless network communication technology), 2G (such as Global System for Mobile Communications (GSM)), 3G (such as Wideband Code Division Multiple Access (WCDMA), 4G (such as Long Term Evolution (LTE)), 4G+ (such as upgraded Long Term Evolution (LTE-Advanced, LTE-A)), or 5G (5th Generation Mobile Communication Technology), or a combination thereof.

[0074] In this embodiment, the cloud desktop service system is connected to single-line lines from multiple operators. This reduces the cost of cloud desktop services based on the low cost of single-line lines. Furthermore, it provides high-quality cloud desktop access services to users of different operators based on these single-line lines, making cloud desktop services more cost-effective and smoother. When accessing a target server through a cloud desktop, the single-line lines from multiple operators are scheduled according to a bandwidth balancing strategy. This balances the peak uplink and downlink bandwidth of a single operator, improving the utilization of existing downlink bandwidth resources. This allows for "peak shaving" of egress bandwidth consumption between different operators, further reducing overall bandwidth costs.
