Abstract

An apparatus and a method for mapping of a tenant based dynamic processor, which classify virtual machine multi queues and processors processing the corresponding multi queues for each tenant that one or more virtual machines are belonged to, dynamically map the virtual machine multi queues that belong to the corresponding tenant to multi processors that belong to the corresponding tenant based on total usages of a network and a processor for each tenant to provide network virtualization to assure network traffic processing of virtual machines that belong to the same tenant not to be influenced by congestion of network traffic that belongs to another tenant.

Claims

1. A network virtualization apparatus for a cloud server system having a plurality of tenants, comprising:

a network interface card having a plurality of virtual machine queues;

a hypervisor performing switching for transferring a received packet of a virtual machine queue of the network interface card to a virtual machine by using a plurality of logical processors and a virtual switch; and

one or more virtual machines for each tenant of the plurality of tenants, which are created by the hypervisor with respect to tenant information which the hypervisor receives from a cloud OS,

wherein the network interface card includes a classifier/sorter that identifies a tenant of the received packet and transfers the packet to one or more virtual machine queues for the tenant of the received packet based on the tenant information and virtual machine information for each tenant of the plurality of tenants received from the hypervisor,

wherein the classifier/sorter controls the packet to be transferred to one or more logical processors mapped to one or more virtual machine queues for each of the same tenant,

wherein the one or more virtual machine queues for each tenant belong to the tenant,

wherein one or more logical processors mapped to the one or more virtual machine queues for each tenant belong to the tenant, and

wherein each virtual machine of the one or more virtual machines for each tenant belong to the tenant.

2. The apparatus of claim 1, wherein the classifier/sorter statically or dynamically manages in a memory a mapping table of the virtual machine queue and the logical processor in accordance with a predetermined control signal.

3. The apparatus of claim 1, wherein the classifier/sorter identifies the tenant based on L2 information or IP information of the received packet.

4. The apparatus of claim 1, wherein the classifier/sorter reflects a traffic processing amount in one or more logical processors in operation, which belong to the same tenant in accordance with a dynamic mapping method in real time to increase or decrease the number of the used logical processors.

5. The apparatus of claim 4, wherein in regard to creation of the logical processor in which the traffic processing amount is equal to or more than an upper threshold, the classifier/sorter operates an additional logical processor by performing a spreading process and maps any one or more virtual machine queues that belong to the corresponding same tenant to the additional logical processor.

6. The apparatus of claim 4, wherein in regard to creation of the logical processor in which the traffic processing amount is equal to or less than a lower threshold, the classifier/sorter controls the corresponding logical processor to be in an idle state by performing a coalescing process and maps the virtual machine queue mapped to the logical processor changed to the idle state to another logical processor in operation.

7. The apparatus of claim 1, wherein the hypervisor creates a plurality of virtual machines that operate as a virtual CPU which operates by different operating systems with respect to the tenant information.

8. The apparatus of claim 1, wherein the logical processor processes the packet received from one or more virtual machine queues and transfers the packet to the virtual machine corresponding to the corresponding virtual machine queue through the virtual switch.

9. A network virtualization method for transferring a packet to one or more virtual machines created by a hypervisor for virtualization by receiving the packet from a network interface card in a cloud server system having a plurality of tenants, the method comprising:

(A) creating, by the hypervisor, one or more virtual machines for each tenant of the plurality of tenants with respect to tenant information which the hypervisor receives from a cloud OS;

(B) identifying, by the network interface card, a tenant of the received packet and transferring the packet to one or more virtual machine queues for a tenant of the plurality of tenants based on the tenant information and virtual machine information for each tenant of the plurality of tenants received from the hypervisor;

(C) controlling, by the network interface card, the packet to be transferred by limiting mapping so as to map a virtual machine queue that belongs to any tenant of the plurality of tenants to one or more logical processors that belong to the same tenant of the plurality of tenants among a plurality of logical processors of the hypervisor; and

(D) transferring, by the logical processor receiving the packet, the packet to one or more virtual machines that belong to the same tenant through a virtual switch of the hypervisor.

10. The method of claim 9, further comprising:

statically or dynamically managing, by the network interface card, in a memory a mapping table of the virtual machine queue and the logical processor in accordance with a predetermined control signal.

11. The method of claim 9, wherein in step (B), the network interface card identifies the tenant based on L2 information or IP information of the received packet.

12. The method of claim 9, further comprising:

reflecting, by the network interface card, a traffic processing amount in one or more logical processors in operation, which belong to the same tenant in accordance with a dynamic mapping method in real time to increase or decrease the number of the used logical processors.

13. The method of claim 12, wherein in regard to creation of the logical processor in which the traffic processing amount is equal to or more than an upper threshold, the network interface card operates an additional logical processor by performing a spreading process and maps any one or more virtual machine queues that belong to the corresponding same tenant to the additional logical processor.

14. The method of claim 12, wherein in regard to creation of the logical processor in which the traffic processing amount is equal to or less than a lower threshold, the network interface card controls the corresponding logical processor to be in an idle state by performing a coalescing process and maps the virtual machine queue mapped to the logical processor changed to the idle state to another logical processor in operation.

15. The method of claim 9, wherein the hypervisor creates a plurality of virtual machines that operate as a virtualized CPU which operates by different operating systems with respect to the tenant information as the one or more virtual machines.

16. The method of claim 9, wherein in step (D), the logical processor processes the packet received from one or more virtual machine queues and transfers the packet to the virtual machine corresponding to the corresponding virtual machine queue through the virtual switch.
