[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] In addition, the step sequence in the following method embodiments is only an example and not a strict limitation.

[0035] Figure 1 Schematic diagram of the architecture of the public cloud network used in the embodiment of the present application. Figure 1 As shown in the figure, in the public cloud network, users (also called tenants) can customize their own private network (i.e. Figure 1The private network in a VPC can be a virtual private cloud (VPC). Different private networks are logically isolated, and users can create and manage virtual machines in their own private networks. Switches are basic network devices that make up a private network and can be used to connect different virtual machines. Gateways are the hubs of private networks and can connect to switches in private networks. They can also be gateway devices that connect private networks to other networks (such as the Internet and the user's local network).

[0036] Among them, switches and gateways are software modules in the proprietary network. Operation and maintenance personnel can configure switches and gateways through the console. Specifically, in response to the configuration operations of the operation and maintenance personnel, the console can trigger the management and control nodes to send configuration information to the switches and gateways by calling APIs to configure the switches and gateways. Figure 1 Configuration path in .

[0037] Take the example of a virtual machine accessing the public network. Figure 2 As shown in the figure, the message for the virtual machine to access the public network is first sent from the virtual machine to the switch (step 1), then from the switch to the gateway in step 2, and then from the gateway to the public network in step 3. Figure 1 The data path in .

[0038] In a public cloud network, multiple important components provide services in the form of clusters. Gateways that carry large amounts of traffic also provide services in the form of clusters, which can be called gateway clusters. The message sent by the virtual machine can carry the virtual network identifier of the user to which the virtual machine belongs (for example, a VXLAN network identifier (VNI)). After receiving the message, the gateway cluster can parse the virtual network identifier, determine the corresponding routing table based on the virtual network identifier, and forward the message based on the routing table. Among them, the corresponding routing table determined based on the virtual network identifier of a user is the routing table of the user. When a user's routing table is configured to a gateway cluster, the gateway cluster can forward messages belonging to the user's virtual machines. The user can be understood as a user carried by the gateway cluster, and the gateway cluster can be understood as the gateway cluster where the user is located. The same gateway cluster can carry multiple users. It should be understood that a routing table may include routing table items, which can be referred to as table items.

[0039] The network clusters in the public cloud network can be distributed in multiple regions. There can be multiple gateway clusters in the same region. Multiple gateway clusters can be deployed in different areas of the same region. Gateway clusters have different delays due to the distance between them, and the number of users that a single gateway cluster can carry is limited by physical resources. In actual applications, gateway clusters may be eliminated or expanded due to changes in the overall planning of the computer room, which will cause user migration.

[0040] Usually, when one or more users need to be migrated out of a gateway cluster, the operation and maintenance personnel need to manually determine the migration plan (i.e., they need to manually determine which gateway cluster to migrate the one or more users to) and manually migrate (i.e., they need to manually delete the user's routing table from the original gateway cluster through the console and configure it to the new gateway cluster) based on the delay caused by the physical distance of the network, the load of the gateway cluster itself, and the characteristics of user needs. This method has the problem of high labor costs.

[0041] In addition, for users who are going to the cloud for the first time, operation and maintenance personnel are also required to manually determine which gateway cluster to configure the user's routing table to based on the delay caused by the physical distance of the network, the load of the gateway cluster itself, and the characteristics of the demand. They also need to manually configure the user's routing table to the determined gateway cluster through the console, which also leads to the problem of high labor costs.

[0042] In order to solve the technical problem of high labor cost in the prior art, in an embodiment of the present application, a target user who needs to be assigned a gateway cluster in a public cloud network is determined, the target user belongs to a target region, the cluster load of multiple gateway clusters deployed in the target region in the public cloud network, and the network delay corresponding to the gateway cluster are obtained, and according to the cluster load and the network delay, the principle of selecting a gateway cluster that matches the demand characteristics of the target user is adopted, and one is selected from the multiple gateway clusters as a target gateway cluster corresponding to the target user, and the routing table of the target user is configured to the target gateway cluster, wherein the demand characteristics of the target user are used to characterize the delay requirements and throughput requirements of the target user, so that the target users who need to be assigned a gateway cluster in the public cloud network (such as new users on the cloud or users who need to migrate from their current gateway cluster) are automatically scheduled to the gateway cluster according to the cluster load and the network delay, without manual scheduling, thereby reducing labor costs.

[0043] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0044] Figure 3 A flow chart of a method for scheduling users to a gateway cluster in a public cloud network provided in an embodiment of the present application. For example, the method provided in this embodiment can be Figure 1 The control node in the execution, such as Figure 3 As shown, the method of this embodiment may include:

[0045] Step 31, determining a target user in a public cloud network to which a gateway cluster needs to be allocated, the target user belongs to a target region, and the number of gateway clusters deployed in the target region in the public cloud network is multiple;

[0046] Step 32, obtaining cluster loads of the multiple gateway clusters and network delays corresponding to the multiple gateway clusters;

[0047] Step 33, according to the cluster load and network delay, a gateway cluster matching the demand characteristics of the target user is selected from the multiple gateway clusters as a target gateway cluster corresponding to the target user, where the demand characteristics of the target user are used to characterize the delay requirements and throughput requirements of the target user;

[0048] Step 34: configure the routing table for the target user to the target gateway cluster.

[0049] In the embodiment of the present application, the target user may be any user in the public cloud network who needs to be assigned a gateway cluster. The users in the public cloud network who need to be assigned a gateway cluster may include users who are already hosted on the gateway cluster and are not going to the cloud for the first time, and / or users who are not hosted on the gateway cluster and are going to the cloud for the first time.

[0050] Optionally, step 31 may specifically include: when it is determined that the first user in the public cloud network needs to be migrated out of the gateway cluster where the first user is currently located, determining the first user as a target user in the public cloud network to which a gateway cluster needs to be allocated.

[0051] Exemplarily, the first user may include a user on a gateway cluster whose cluster traffic load is greater than a traffic load threshold. In this case, in one embodiment, the method provided in this embodiment may further include: determining at least one user on a gateway cluster whose cluster traffic load is greater than a traffic load threshold as a user that needs to be migrated from the gateway cluster where the user is currently located. Thus, users on a gateway cluster with an excessively high traffic load may be migrated out, so as to achieve advance traffic scheduling by prejudging the cluster traffic load.

[0052] And / or exemplary, the first user may include a user on a gateway cluster that needs to be eliminated. In this case, in one embodiment, the method provided in this embodiment may further include: determining all users on the gateway cluster that needs to be eliminated as users that need to be migrated out of the gateway cluster they are currently in. Thus, the users on the gateway cluster that needs to be eliminated can be migrated out.

[0053] And / or exemplary, the first user may include users on the original gateway cluster in the area where the number of gateway clusters is expanded. In this case, in one embodiment, the method provided in this embodiment may also include: determining multiple users on the original gateway cluster in the area where the number of gateway clusters is expanded as users that need to be migrated from the gateway cluster they are currently in. Thereby, users on the original gateway cluster in the area where the number of gateway clusters is expanded are migrated to the new gateway cluster.

[0054] And / or optionally, step 31 may specifically include: when determining that the second user is a user who accesses the cloud for the first time in the public cloud network, determining the second user as a target user in the public cloud network to which a gateway cluster needs to be allocated. The second user is a user who accesses the cloud for the first time in the public cloud network.

[0055] When purchasing a virtual machine, the user can select a region to determine the region where the computing device running the purchased virtual machine is located. Therefore, the region to which the target user belongs can be recorded as the target region. In the embodiment of the present application, the division standard of the region is not limited, for example, one province can be one region.

[0056] In an embodiment of the present application, there are multiple gateway clusters deployed in a target area in a public cloud network, and the cluster loads of the multiple gateway clusters can be obtained.

[0057] The cluster load of the gateway cluster may specifically be any type of information that can characterize the overall load of the gateway cluster. The cluster load of the gateway cluster may include cluster traffic load, and further may include cluster table item load. The cluster traffic load may represent the traffic carried by the gateway cluster, and the cluster table item load may represent the table item contained by the gateway cluster.

[0058] The cluster traffic load may include a cluster traffic usage rate, and may further include a cluster traffic growth score. The cluster traffic usage rate may satisfy the following formula (1), and the cluster traffic growth score may satisfy the following formula (2).

[0059]

[0060]

[0061] In formula (1) and formula (2), f_util represents the cluster traffic utilization rate, f_usage represents the cluster traffic size at the current moment, and f_capacity represents the maximum traffic size that the cluster can carry; f_grow_score represents the cluster traffic growth score, t1 and t2 represent time, t2 is later than t1, f_usage1 represents the cluster traffic size at t1, and f_usage2 represents the cluster traffic size at t2.

[0062] For example, for any gateway cluster in a public cloud network, if its f_util>=f_util_threshold, one or more users carried on the gateway cluster can be used as target users, so that the one or more users carried on the gateway cluster can be migrated to a gateway cluster with low traffic usage. Wherein, f_util_threshold can represent a traffic usage threshold, and f_util_threshold can be an empirical value.

[0063] Furthermore, for any gateway cluster in the public cloud network, if its f_growth_score>=f_growth_score_threshold, one or more users hosted on the gateway cluster can be used as target users, so that one or more users on the gateway cluster can be migrated to a gateway cluster with low traffic level. Wherein, f_growth_score_threshold can represent the traffic growth score threshold, and f_growth_score_threshold can be an empirical value.

[0064] The cluster entry load may include a cluster entry usage rate, and may further include a cluster entry growth score. The cluster entry usage rate may satisfy the following formula (3), and the cluster entry growth score may satisfy the following formula (4).

[0065]

[0066]

[0067] In formula (3) and formula (4), c_util represents the cluster table item usage rate, c_usage represents the number of cluster table items at the current time, and c_capacity represents the maximum number of table items that the cluster can accommodate; c_grow_score represents the cluster table item growth score, t1 and t2 represent time, t2 is later than t1, c_usage1 represents the number of cluster table items at t1, and c_usage2 represents the number of cluster table items at t2.

[0068] Optionally, in addition to obtaining the cluster load of the multiple gateway clusters, the cluster health status of the multiple gateway clusters can also be obtained. The cluster health status can be healthy or unhealthy, so as to avoid the problem of scheduling the target user to a gateway cluster with an unhealthy cluster health status, resulting in the inability to forward the user's message abnormally, causing losses to the user.

[0069] For example, Figure 4As shown, the information collection module can be used to collect the cluster health status, cluster table item load and cluster traffic load of the gateway cluster. It should be understood that the information collection module is a functional module. In one embodiment, the information collection module can be included in the execution subject of the method provided in the embodiment of the present application, for example, it can be included in the management and control node. In this case, obtaining the cluster load of the multiple gateway clusters in step 31 can specifically include collecting the cluster load of the multiple gateway clusters.

[0070] Among them, for the cluster health status, for example, the traffic size of a single gateway in the gateway cluster can be queried, and the traffic size of the gateway cluster can be obtained by statistics. If the statistical graph is a smooth curve without a sharp drop, the cluster health status of the gateway cluster can be considered healthy, otherwise the cluster health status of the gateway cluster can be considered unhealthy. For another example, the number of abnormal messages of a single gateway in the gateway cluster can be queried, and the number of abnormal messages of the gateway cluster in the recent period can be obtained by statistics. If the number of abnormal messages of the network cluster is less than the preset threshold, the cluster health status of the gateway cluster can be considered healthy, otherwise the health status of the gateway cluster can be considered unhealthy.

[0071] For cluster entry load, for example, the number of rows of routing entries sent to a single gateway in the gateway cluster may be received, and the cluster entry load of the gateway cluster may be obtained based on the number of rows of routing entries sent to the single gateway in the gateway cluster.

[0072] For the cluster traffic load, for example, the traffic load of a single gateway in the gateway cluster can be queried, and the cluster traffic load of the gateway cluster can be statistically obtained based on the queried traffic load of the single gateway in the gateway cluster.

[0073] In one embodiment, the management and control node may count the cluster load of the gateway cluster once every period of time, so that the management and control node can dynamically obtain the cluster load of the gateway cluster.

[0074] In an embodiment of the present application, in addition to obtaining the cluster load of the multiple gateway clusters, the network delay corresponding to the multiple gateway clusters can also be obtained. Among them, the network delay corresponding to the gateway cluster may be related to the counterpart corresponding to the target user, and the counterpart corresponding to the target user may be related to the service that the target user needs to use. In one embodiment, when the target user needs to use the services provided by one or more other virtual machines on the cloud, the counterpart corresponding to the target user may include the one or more other virtual machines. In another embodiment, when the target user needs to use the services provided by the Internet Data Center (IDC), the counterpart corresponding to the target user may include the Internet Data Center.

[0075] Exemplarily, when the counterpart corresponding to the target user includes one or more other virtual machines on the cloud, the network delay corresponding to a gateway cluster may include the network delay between the virtual machine under the gateway cluster and any other virtual machine among the one or more other virtual machines or a virtual machine under the same gateway cluster as the one or more other virtual machines.

[0076] Exemplarily, when the opposite end corresponding to the target user includes an Internet data center, the network delay corresponding to a gateway cluster may include the network delay between the virtual machine under the gateway cluster and the gateway of the Internet data center.

[0077] In actual applications, you can select a virtual machine from a gateway cluster to detect network latency. Virtual machines selected from different gateway clusters can detect each other. A virtual machine selected from a gateway cluster can also detect the network latency of the gateway of an Internet data center. A virtual machine selected from a gateway cluster can also detect the network latency of another virtual machine in the same gateway cluster. For example, Figure 5 As shown, it can be detected that the network delay between the virtual machine in the gateway cluster and the gateway of the Internet data center is 3 milliseconds (ms), and the network delay between virtual machines in the same gateway cluster or in different gateway clusters is 2ms.

[0078] In one embodiment, the virtual machines under the gateway cluster may detect the network delay at regular intervals and notify the control node of the detected network delay, so that the control node can dynamically obtain the network delay corresponding to the gateway cluster.

[0079] In an embodiment of the present application, after obtaining the cluster loads of the multiple gateway clusters and the network delays corresponding to the multiple gateway clusters, one can select a target gateway cluster corresponding to the target user from the multiple gateway clusters based on the cluster load and the network delay, using the principle of selecting a gateway cluster that matches the demand characteristics of the target user. The demand characteristics of the target user can be used to characterize the delay requirements and throughput requirements of the target user. It should be understood that when the number of target users is multiple, step 33 can be performed for each of the multiple target users.

[0080] For example, assuming that the target user's demand characteristics are high requirements for latency and low requirements for throughput, such as users who provide transaction services to a small number of people, you can choose a gateway cluster with a smaller network latency and a higher cluster load as the target gateway cluster.

[0081] For another example, suppose the target users have higher requirements for latency and lower requirements for throughput, such as users who provide transaction services to a large number of people. Therefore, a gateway cluster with a smaller network latency and a lower cluster load can be selected as the target gateway cluster.

[0082] For another example, suppose the target user's demand characteristics are high requirements for throughput and low requirements for latency, such as users who provide data upload services. Therefore, you can select a gateway cluster with a lighter cluster load and a correspondingly larger network latency as the target gateway cluster.

[0083] In one embodiment, step 33 may specifically include: selecting, from the multiple gateway clusters, a gateway cluster whose cluster load is less than a load threshold and whose network delay and cluster load meet the requirements of the target user as the target gateway cluster corresponding to the target user. Taking the cluster load including the cluster table item load and the cluster traffic load as an example, a gateway cluster whose cluster table item load is less than the table item load threshold, the cluster traffic load is less than the traffic load threshold, and whose network delay and cluster load meet the requirements of the target user may be selected from the multiple gateway clusters as the target gateway cluster corresponding to the target user.

[0084] Taking the cluster entry load including the cluster entry usage rate (c_util_threshold) and the cluster entry growth score (c_growth_score) as an example, for any gateway cluster among the multiple gateway clusters, if its c_growth_score>=c_growth_score_threshold, the target user can be suspended from being assigned to the gateway cluster, so that the target user can be not assigned to the gateway cluster with a high entry usage rate; and for any gateway cluster among the multiple gateway clusters, if c_util>=c_util_threshold, the target user can be suspended from being assigned to the gateway cluster, so that the target user can be not assigned to the gateway cluster with a high entry water level. Among them, c_growth_score_threshold and c_util_threshold can be empirical values.

[0085] Taking the cluster traffic load including the cluster traffic utilization rate (f_util_threshold) and the cluster traffic growth score (f_growth_score) as an example, for any gateway cluster among the multiple gateway clusters, if its f_growth_score>=f_growth_score_threshold, the allocation of the target user to the gateway cluster can be suspended, so that the target user is not allocated to the gateway cluster with a high traffic utilization rate; and, for any gateway cluster among the multiple gateway clusters, f_util>=f_util_threshold, the allocation of the target user to the gateway cluster can be suspended, so that the target user is not allocated to the gateway cluster with a high traffic water level.

[0086] In another embodiment, step 33 may specifically include: from the multiple gateway clusters, selecting a gateway cluster whose cluster health status is healthy, whose cluster load is less than the load threshold, and whose network delay and cluster load meet the needs of the target user as the target gateway cluster corresponding to the target user. Taking the cluster load including the cluster table item load and the cluster traffic load as an example, a gateway cluster whose cluster health status is healthy, whose cluster table item load is less than the table item load threshold, whose cluster traffic load is less than the traffic load threshold, and whose network delay and cluster load meet the needs of the target user may be selected from the multiple gateway clusters as the target gateway cluster corresponding to the target user.

[0087] Optionally, when selecting a corresponding target gateway cluster for a target user, the size of the target user may also be considered to achieve dispersing users of different sizes in different gateway clusters, thereby facilitating improving resource utilization. Based on this, in one embodiment, step 33 may specifically include: according to the cluster load and the network delay, in accordance with the strategy of dispersing users of the same size in different gateway clusters and adopting the principle of selecting a gateway cluster that matches the characteristics of the target user's needs, one of the multiple gateway clusters is selected as the target gateway cluster corresponding to the target user. Exemplarily, in accordance with the strategy of dispersing users of the same size in different gateway clusters, a gateway cluster whose cluster load is less than a load threshold and whose network delay and cluster load meet the characteristics of the target user's needs may be selected from the multiple gateway clusters as the target gateway cluster corresponding to the target user.

[0088] For example, Figure 6 In the example, multiple users in the same ellipse can represent users with the same demand characteristics, users of different sizes in the same ellipse can represent users of different scales, and users in the same ellipse can represent users whose selected gateway cluster is the same gateway cluster.

[0089] In an embodiment of the present application, after selecting a target gateway cluster corresponding to a target user from multiple gateway clusters, the routing table for the target user can be configured to the target gateway cluster corresponding to the target user. When a target user is a user who is going to the cloud for the first time, the routing table for the target user can be directly configured to the target gateway cluster corresponding to the target user. When a target user is a user who needs to be migrated from the gateway cluster where the target user is currently located, the routing table for the target user can be deleted from the gateway cluster where the target user is currently located, and the routing table for the target user can be configured to the target gateway cluster corresponding to the target user, so that the target user can be migrated from the original gateway cluster to the new gateway cluster.

[0090] For example, if there are two gateway clusters deployed in the same region, namely gateway cluster A and gateway cluster B, Figure 7 As shown, the information collection module 71 can collect cluster load information of cluster A and cluster B.
