It should be noted that the application scenarios introduced below are only used to illustrate the embodiments of the present application and are not limiting. In the specific implementation, the technical solutions provided by the embodiments of the present application can be flexibly applied according to actual needs.

[0051] FIG. 1 is a schematic diagram of a resource adjustment architecture provided by the present application. As shown in FIG. 1, the architecture includes an SDN controller 100, a load manager 101, a computing service 102, a load balancing service 103, a computing cluster including N (N is an integer greater than 0) computing nodes, and a load balancing cluster including M (M is an integer greater than 0) load balancing network elements. The load manager 101 is connected with the SDN controller 100, the computing service 102, and the load balancing service 103, respectively. The SDN controller is connected with the computing cluster and the load balancing cluster, which will be introduced one by one as follows.

[0052] The N computing nodes each run a virtual switch that carries a backend service and provides network interworking services for the virtual switch and the load balancing cluster and other devices, for example, as shown in FIG. 1, the computing node 1 runs the virtual switch 1 and the virtual switch 2; the N computing nodes are controlled by the computing service 102.

[0053] The load balancing cluster provides load balancing services for each virtual switch and is controlled by the load balancing service 103.

[0054] After receiving the resource adjustment request sent by the SDN controller 100, the load manager 101 can obtain relevant resource adjustment information based on the computing service 102, the load balancing service 103, etc., and send the resource adjustment information to the SDN controller.

[0055] The SDN controller 100 is the control center of the entire network, can monitor the traffic of each virtual switch, determine the bandwidth occupancy of each virtual switch based on the traffic, send a resource adjustment request to the load manager 101, and perform a resource adjustment operation in response to the resource adjustment information sent by the load manager 101 based on the resource adjustment request, thereby adjusting the traffic direction of the network and realizing the expansion and contraction of network resources through the expansion and contraction of computing resources.

[0056] To further illustrate the technical solutions provided by the embodiments of the present application, the following will be described in detail in conjunction with the drawings and specific embodiments. Although the embodiments of the present application provide the method operation steps as described in the following embodiments or as shown in the drawings, more or fewer operation steps can be included in the method based on conventional or non-creative labor. The execution order of these steps is not limited to the execution order provided by the embodiments of the present application in the logical sense. The method can be executed in the order shown in the embodiments or drawings or in parallel during actual processing or device execution.

[0057] FIG. 2 is a flowchart of a resource adjustment method provided by the present application, which can be executed by an SDN controller (such as the SDN controller 100 shown in FIG. 1). As shown in FIG. 2, the flow includes the following steps:

[0058] 201: Determine the bandwidth occupancy of the virtual switch according to the first traffic and the second traffic sent by the virtual switch.

[0059] The first traffic and the second traffic are traffic sent by the virtual switch (such as the virtual switch 1 shown in FIG. 1) at different times.

[0060] In some embodiments, the SDN controller can receive the first traffic and the second traffic sent by the virtual switch in the following manner, taking the above virtual switch 1 as an example, specifically:

[0061] According to a set period (for example, every 5 seconds, or every two minutes), the SDN controller sends a traffic statistics message to the computing node 1, the traffic statistics message including the NIC information of the virtual switch 1 (for example, the IP address of the virtual switch 1, the port corresponding to the virtual switch 1 on the OVS, etc.); after the computing node 1 receives the traffic statistics message, the computing node 1 feeds back a traffic statistics response message to the SDN controller, the traffic statistics response message including the first traffic of the virtual switch 1; similarly, the second traffic of the virtual switch 1 is also acquired in the next period of time according to this manner.

[0062] In some embodiments, according to the first traffic and the second traffic sent by the virtual switch, the bandwidth occupancy of the virtual switch can be determined according to the byte number of the first traffic and the second traffic, and the receiving time of the first traffic and the second traffic; then, according to the network speed and the bandwidth threshold of the virtual switch, the bandwidth occupancy of the virtual switch is determined.

[0063] In some embodiments, the network speed satisfies the following expression: b' = (d2-d1) / (t2-t1); wherein d2 is the byte number of the second traffic, d1 is the byte number of the first traffic, t2 is the receiving time of the second traffic, and t1 is the receiving time of the first traffic.

[0064] In some embodiments, the bandwidth occupancy satisfies the following expression: v = (b-b') / b; wherein b is the bandwidth threshold of the virtual switch, and b' is the network speed of the virtual switch.

[0065] In the embodiments of the present application, the SDN controller can monitor the traffic trend of each virtual switch on the computing node in real time, which facilitates subsequent dynamic scaling of computing resources according to network resources (such as bandwidth occupancy).

[0066] 202: based on the bandwidth occupancy, sending a resource adjustment request to the load manager.

[0067] In some embodiments, based on the bandwidth occupancy, sending a resource adjustment request to the load manager (such as the load manager 101 shown in FIG. 1) can be: if the bandwidth occupancy is greater than a first bandwidth occupancy threshold (for example, 80%); if so, sending a resource expansion request to the load manager; wherein the resource expansion request is used to request to create a new virtual switch.

[0068] In some embodiments, when the load manager receives the resource expansion request, a virtual switch 3 (new virtual switch) running a backend service can be created using the same image in the virtual private cloud where the virtual switch (e.g., virtual switch 1) is located, and the virtual switch 3 can be mounted on the computing node 2. The resource expansion information related to the created virtual switch 3 can be sent to the SDN controller, so that the SDN controller performs corresponding resource expansion operation based on the resource expansion information.

[0069] In some embodiments, the resource expansion information can include the computing node on which the new virtual switch is mounted, the network card information of the new virtual switch, the IP address of the new virtual switch, and the like.

[0070] In some embodiments, based on the bandwidth occupancy, sending the resource adjustment request to the load manager can also be: if the bandwidth occupancy is less than a second bandwidth occupancy threshold (e.g., 30%) and exceeds a time threshold (e.g., 1 minute), sending a resource contraction request to the load manager; wherein the resource expansion request is used to request to remove the virtual switch, and the second bandwidth occupancy threshold is less than the first bandwidth occupancy threshold.

[0071] In some embodiments, when the load manager receives the resource contraction request, the network card information of the virtual switch (e.g., virtual switch 1) can be obtained as resource contraction information, and the resource contraction information about the virtual switch can be sent to the SDN controller.

[0072] In some embodiments, the resource contraction information at least includes the computing node on which the virtual switch is mounted, the network card information of the virtual switch, the IP address of the virtual switch, and the like.

[0073] In some other embodiments, when the SDN controller determines the bandwidth occupancy, the bandwidth occupancy can be directly sent to the load manager, so that the load manager determines whether resource expansion or resource contraction is needed based on the bandwidth occupancy.

[0074] 203: Perform resource adjustment operation in response to the resource adjustment information sent by the load manager based on the resource adjustment request.

[0075] In some embodiments, performing resource adjustment operation in response to the resource adjustment information sent by the load manager based on the resource adjustment request includes the following cases:

[0076] Embodiment 1, for the case that the resource expansion request is used to request to create a new virtual switch.

[0077] In response to the resource expansion information sent by the load manager based on the resource expansion request, performing a resource expansion operation can include: generating a first flow direction table and a second flow direction table according to the resource expansion information; wherein the first flow direction table is used to indicate the flow direction of the new virtual switch on the computing cluster; the second flow direction table is used to indicate the flow direction of the new virtual switch on the load balancing cluster; then, the first flow direction table is sent to the computing cluster, and the second flow direction table is sent to the load balancing cluster.

[0078] Further, in order to open up the network of the new virtual switch and the load balancing cluster on the computing cluster, the first flow direction table can include the flow direction table (flow direction example table 1) of the new virtual switch (virtual switch 3) on the computing node (computing node 2) where the new virtual switch is located, as shown in Table 1, which exemplarily shows the flow direction example table 1; and can also include the flow direction table (flow direction example table 2) of the new virtual switch on the computing node where the other virtual switch is located, as shown in Table 2, which exemplarily shows the flow direction example table 2.

[0079] Table 1: Flow direction example table 1

[0080] In the table 1, the virtual switch 1 (vm-1) and the virtual switch 2 (vm-2) are located on the computing node 1 as shown in FIG. 1, the ip address of the vm-1 is 192.168.1.2, and the ip address of the vm-2 is 192.168.1.3; the vm-1 and the vm-2 are located in the same VPC, and the vni value of the VPC is 5000; the virtual switch 3 (vm-3) is located on the computing node 2, the ip address of the vm-3 is 192.168.1.4, and the corresponding virtual network card is port-3; the ip address of the load balancing cluster in the VPC is 192.168.1.100, and when the destination address is 192.168.1.100, the message will pass through the load balancing cluster and then be forwarded to the vm-1 and the vm-2.

[0081] Table 2: Flow direction example table 2

[0082] In the table 2, the virtual machine network card corresponding to the vm-1 is port-1, and the virtual network card corresponding to the vm-2 is port-2.

[0083] Further, in order to open up the network of the new virtual switch and the load balancing cluster on the computing cluster, the first flow direction table can include the flow direction table (flow direction example table 1) of the new virtual switch (virtual switch 3) on the computing node (computing node 2) where the new virtual switch is located, as shown in Table 1, which exemplarily shows the flow direction example table 1; and can also include the flow direction table (flow direction example table 2) of the new virtual switch on the computing node where the other virtual switch is located, as shown in Table 2, which exemplarily shows the flow direction example table 2.

[0084] Table 3: Flow direction example table 3

[0085] In some embodiments, the first flow table is sent to the computing cluster, and the second flow table is sent to the load balancing cluster, and after the corresponding expansion operation is completed, the traffic of the new virtual switch can be periodically collected to determine the bandwidth occupation of the new virtual switch. If at a certain moment, the SDN controller detects that the bandwidth occupation rate of the new virtual switch is lower than a certain threshold, and exceeds a time threshold, the load manager can be called to perform a corresponding shrinkage operation at this time. If at a certain moment, the SDN controller detects that the bandwidth occupation rate of the new virtual switch exceeds a certain threshold, the load manager can be called to perform a corresponding expansion operation.

[0086] In the embodiments of the present application, in the case of resource expansion, a new virtual switch can be created by the load manager, and based on the resource expansion information obtained from the load manager, a first flow table on the computing cluster and a second flow table on the load balancing cluster are generated to make the network of the new virtual switch pass through the computing cluster and the load balancing cluster, thereby sharing the load pressure of other virtual switches, dynamically adjusting the number of backend services, and avoiding network congestion.

[0087] Embodiment 2, for the case of requesting to delete the virtual switch according to the above resource shrinkage request.

[0088] In response to the resource shrinkage information sent by the load manager based on the resource shrinkage request, the resource shrinkage operation can include: generating a first instruction and a second instruction according to the resource shrinkage information; wherein the first instruction is used to instruct to delete the flow table of the virtual switch on the load balancing cluster, and the second instruction is used to instruct to delete the flow table of the virtual switch on the computing cluster; sending the first instruction to the load balancing cluster, and sending the second instruction to the computing cluster.

[0089] For example, taking the virtual switch 1 shown in FIG. 1 as an example:

[0090] First, after receiving the resource shrinkage request, the load manager can call the computing service (such as the computing service 102 shown in FIG. 1) to delete the virtual switch 1 from the computing cluster, and record the information related to the virtual switch 1 (for example, the IP address of the virtual switch 1, the network card, the VPC where it is located, the computing node where it is located, etc.), and feed back these information to the SDN controller as resource shrinkage information.

[0091] Second, after receiving the resource shrinkage information, the SDN controller can generate a first instruction based on the information related to the load balancing cluster in the resource shrinkage information, and generate a second instruction based on the information related to the computing cluster.

[0092] Then, the first instruction is sent to the load balancing cluster to make the load balancing cluster delete the flow direction table related to the virtual switch 1, and the second instruction is sent to the computing cluster to make each computing node on the computing cluster delete the flow direction table related to the virtual switch 1.

[0093] In the embodiments of the present application, in the case of needing to perform resource scaling, unnecessary virtual switches can be deleted by the load manager to avoid waste of resources, and based on the resource scaling information obtained from the load manager, a first instruction for instructing the load balancing cluster and a second instruction for instructing the computing cluster are generated to make targeted deletion of unnecessary flow direction tables to avoid subsequent traffic from going to the wrong direction.

[0094] In the embodiments of the present application, the bandwidth occupancy rate of the virtual switch can be determined according to the first traffic and the second traffic sent by the virtual switch, the bandwidth (network resource) of the virtual switch is monitored in real time, further, based on the bandwidth occupancy rate, a resource adjustment request is sent to the load manager; in response to the resource adjustment information sent by the load manager based on the resource adjustment request, a resource adjustment operation is performed, so that the network resource and the computing resource can be associated by the load manager, the adaptive adjustment of the computing resource is performed based on the bandwidth occupancy rate, so as to avoid network congestion or waste of resources, and the overall service quality is improved.
