Exemplarily, referring to fig. 1, a detailed flowchart of a bandwidth allocation method provided in an embodiment of the present application is shown, where the method is applied to a cloud operating system in a cloud platform, and the method includes the following steps:
step 100: and configuring bandwidth allocation strategies corresponding to the business services respectively based on the flow attributes of different business services, wherein one bandwidth allocation strategy is used for ensuring the minimum bandwidth of the associated virtual machine when the associated virtual machine executes the relevant business service.
In this embodiment of the present application, the cloud operating system may include a bandwidth allocation policy management platform, where the bandwidth allocation policy management platform configures, in advance, bandwidth allocation policies corresponding to respective service services based on traffic attributes of the respective service services, for example, a bandwidth allocation policy 1(qos1) is configured according to an Office Automation (OA) network, a bandwidth allocation policy 2(qos2) is set according to an access-specified web service (e.g., http.xxx.com), or a bandwidth allocation policy 3(qos3) is set according to a tcp service, and a bandwidth policy 4(qos4) is set according to a udp service.
Specifically, in this embodiment of the present application, the traffic attributes of the service attributes at least include: domain name information, and/or, protocol information, and/or, port information, and/or, IP address/MAC address information.
In practical applications, a bandwidth allocation policy may include a combination of at least one matching condition and a minimum guaranteed bandwidth value, for example, it is assumed that the at least one matching condition included in the bandwidth allocation policy is: condition 1, domain name information carried by traffic, condition 2, port information used for forwarding the traffic, condition 3, protocol information for forwarding the traffic; if the minimum guaranteed bandwidth is 200M, it is necessary to guarantee the minimum bandwidth that can be used by the traffic that satisfies the above 3 conditions at the same time.
That is, in the embodiment of the present application, a preferable implementation manner is that, when a pending traffic is detected, the traffic is matched with the condition 1, if the pending traffic is matched, the traffic is continuously matched with the condition 2, if the pending traffic is matched, the traffic is continuously matched with the condition 3, and if the pending traffic is matched, it is determined that the traffic simultaneously satisfies the above 3 conditions, that is, the bandwidth allocation policy is hit.
In the embodiment of the present application, the configuration manner of the bandwidth allocation policy is various, and for example, the configuration may be performed based on a domain name and a protocol included in the traffic attribute, or may be performed based on a port and a protocol. That is, each flow attribute combination may be performed according to application scenarios of different users (enterprises) and/or different requirements, and in the embodiment of the present application, no specific limitation is made herein.
Step 110: and creating virtual machines for running different business services, and respectively setting the priority of each virtual machine based on the business service run by each virtual machine.
In this embodiment of the present application, each virtual machine needs to be created on each physical host of the cloud platform, in this embodiment of the present application, the cloud operating system may further include a virtual machine management platform, based on the virtual machine management platform, virtual machines for running different service services may be created on each physical host, and based on parameters such as importance of the service services run by each virtual machine, the priority of each virtual machine is set, where, for a virtual machine on the same physical host, the higher the priority is, the higher the authority to use the bandwidth is.
In the embodiment of the present application, the current available bandwidths of the physical hosts in the cloud platform are different, and the bandwidths required by the virtual machines to be created for running different business services are also different, so when creating the virtual machines for running different business services, a preferred implementation manner is to respectively determine the size of the bandwidth required by the virtual machines to be created for running different business services and the size of the physical bandwidth currently available to the physical hosts; and creating each virtual machine to be created to a corresponding physical host based on the size of the bandwidth required by the virtual machine to be created for running different business services and the size of the physical bandwidth currently available by each physical host.
Further, in the embodiment of the present application, when creating each virtual machine to be created onto a corresponding physical host based on the size of the bandwidth required by the virtual machine to be created for running different service services and the size of the currently usable physical bandwidth of each physical host, a preferred implementation manner is to determine whether a target physical host whose currently usable bandwidth is greater than or equal to the bandwidth required by the target virtual machine to be created exists in each physical host; if a target physical host with the current available physical bandwidth larger than or equal to the bandwidth required by the target virtual machine to be created exists in the physical hosts, creating the target virtual machine on the target physical host; if there is no target physical host with the current available physical bandwidth larger than or equal to the bandwidth required by the target virtual machine to be created in the physical hosts, creating the target virtual machine on the physical host with the maximum current available physical bandwidth, wherein when the total bandwidth required by each virtual machine created in one physical host is larger than the current available bandwidth of the physical host, the bandwidth is allocated to each virtual machine based on the priority of each virtual machine.
That is, when the physical host bandwidth resources in the cloud platform are sufficient, for example, the currently available bandwidth of the physical host 1 is 100M, and the bandwidth required by the virtual machine X to be created for running the business service 1 is 80M, the virtual machine X can be created on the physical host 1. When the bandwidth required by the virtual machine Y to be created for running the business service 2 is 200M, the currently available bandwidth of each physical machine in the current cloud platform is less than 200, and the currently available bandwidth of the physical host 2 is the largest, the virtual machine Y may be created on the physical host 2 with the largest currently available bandwidth among the physical hosts.
Illustratively, referring to fig. 2, a schematic diagram of creating a virtual machine according to an embodiment of the present application is provided. The virtual machines to be created include a virtual machine 1, a virtual machine 2 and a virtual machine 3, the bandwidth required by the virtual machine 1 is 100M, the bandwidth required by the virtual machine 2 is 20M, and the bandwidth required by the virtual machine 3 is 30M, when the cloud operating system detects that the bandwidth currently available to the physical host 1 is 200M and the bandwidth currently available to the physical host 2 is 80M, a preferred implementation is to create the virtual machine 1 on the physical host 1 and create the virtual machine 2 and the virtual machine 3 on the physical host 2, of course, since the total bandwidth required by the virtual machine 1, the virtual machine 2 and the virtual machine 3 is 130M and the bandwidth currently available to the physical host 1 is 200M, then another preferred implementation is to create the virtual machine 1, the virtual machine 2 and the virtual machine 3 on the physical node 1.
Illustratively, referring to fig. 3, a schematic diagram is created for another virtual machine provided in the embodiment of the present application. The virtual machines to be created comprise a virtual machine 1, a virtual machine 2 and a virtual machine 3, the bandwidth required by the virtual machine 1 is 100M, the bandwidth required by the virtual machine 2 is 20M, the bandwidth required by the virtual machine 3 is 30M, and the cloud operating system detects that only the physical host 3 has the currently usable bandwidth of 50M and the other physical hosts have no currently usable bandwidth, then the virtual machine 1, the virtual machine 2 and the virtual machine 3 can be created on the physical node 3, at this time, since the corresponding priority is set when the virtual machine is created (for example, the priority of the virtual machine 1 is high, the priority of the virtual machine 2 is medium, and the priority of the virtual machine 3 is low), the physical host 3 can use the bandwidth preferentially for the virtual machine 1, when the virtual machine 1 is idle, the physical host 3 can use the bandwidth preferentially for the virtual machine 2, when the virtual machine 1 and the virtual machine 2 are idle, the physical host 3 can currently use bandwidth first for the virtual machine 3.
Step 120: and respectively establishing association relations among the bandwidth allocation strategies corresponding to the virtual machines based on the service services operated by the virtual machines, wherein at least one target virtual machine is operated on one physical host, and the physical host allocates the bandwidth to the target virtual machines based on the bandwidth allocation strategies associated with the target virtual machines and the priorities of the target virtual machines.
In this embodiment of the present application, after a virtual machine is created on each physical host, a bandwidth allocation policy configured based on traffic attributes of the virtual machine needs to be determined according to the traffic service operated by the virtual machine, for example, if the virtual machine 1 is used to operate the traffic service 1, the virtual machine 2 is used to operate the traffic service 2, the virtual machine 3 is used to operate the traffic service 3, and the bandwidth allocation policy 1 is configured based on the traffic attributes of the traffic service 1, the bandwidth allocation policy 2 is configured based on the traffic attributes of the traffic service 2, and the bandwidth allocation policy 3 is configured based on the traffic attributes of the traffic service 3, then after the virtual machine 1, the virtual machine 2, and the virtual machine 3 are created, an association relationship between the virtual machine 1 and the bandwidth allocation policy 1 is established, and an association relationship between the virtual machine 2 and the bandwidth allocation policy 2 is established, and establishing an association relation between the virtual machine 3 and the bandwidth allocation strategy 3. When the subsequent flow forwarding is performed, the bandwidth allocation strategy 1 can be adopted to ensure the forwarding of the service flow of the virtual machine 1, the bandwidth allocation strategy 2 can be adopted to ensure the forwarding of the service flow of the virtual machine 2, and the bandwidth allocation strategy 3 can be adopted to ensure the forwarding of the service flow of the virtual machine 3.
Further, in this embodiment of the present application, the bandwidth allocation method may further include the following steps: based on the virtual switch technology, a corresponding forwarding flow table is set for each virtual machine, and the hit priority of each forwarding flow table is set, wherein when the traffic of each service is forwarded, the traffic of the forwarding flow table with higher hit priority is forwarded preferentially based on the hit priority of each forwarding flow table.
Exemplarily, referring to fig. 4, a flow table setting schematic diagram provided in the embodiment of the present application is shown, where a flow table 1 is formed based on a bandwidth allocation policy 1 associated with a virtual machine 1, and if the priority of the virtual machine 1 is high, the priority of the flow table 1 corresponding to the virtual machine 1 is high, and the hit priority is high; forming a flow table 2 based on a bandwidth allocation policy 2 associated with the virtual machine 2, wherein the priority of the virtual machine 2 is medium, and then the priority of the flow table 2 corresponding to the virtual machine 2 is medium, and the hit priority is medium; flow table 3 is formed based on bandwidth allocation policy 3 associated with virtual machine 3, and the priority of virtual machine 32 is low, so that the priority of flow table 3 corresponding to virtual machine 3 is low, and the hit priority is low.
