Abstract

Cloud computing platforms having computer-readable media that perform methods to shape virtual machine communication traffic. The cloud computing platform includes virtual machines and a controller. The controller limits the traffic associated with the virtual machines to enable the virtual machines to achieve desired communication rates, especially when a network servicing the virtual machines is congested. The controller may drop communication messages associated with the virtual machines based on a drop probability evaluated for the virtual machines.

First claim

The technology claimed is:

1. A datacenter platform that utilizes one or more processors configured to perform steps that limit transmission communication messages, the steps comprising:
detecting congestion on a network servicing virtual machines running one or more datacenter applications;
confirming whether specified communication rates for the virtual machines in the datacenter platform are achieved; and
dropping communication messages for the virtual machines based on whether the specified communication rates are achieved.

2. The datacenter platform of claim 1 , wherein the specified communication rates are determined by a service level agreement.

3. The datacenter platform of claim 1 , wherein the specified communication rates are set based on the congestion detected on the network.

4. The datacenter platform of claim 3 , wherein the specified communication rates are set by an administrator.

5. The datacenter platform of claim 3 , wherein the specified communication rates are set automatically.

6. The datacenter platform of claim 3 , wherein the specified communication rates are automatically decreased as congestion on the communication network increases.

7. The datacenter platform of claim 1 , wherein the specified communication rates comprise a desired communication rate.

8. A system for limiting transmission communication messages, comprising:
computing devices;
one or more hardware computer-readable media having embodied thereon computer-useable instructions that, when executed by one or more of the computing devices, provide one or more virtual machines;
one or more hardware computer-readable media having embodied thereon computer-useable instructions that, when executed by one or more of the computing devices, perform the steps of:
detecting congestion on a network servicing the virtual machines running one or more datacenter applications;
confirming whether specified communication rates for virtual machines in the datacenter platform are achieved; and
dropping communication messages for the virtual machines based on whether the specified communication rates are achieved.

9. The system of claim 8 , wherein the specified communication rates are set based on one or more of a service level agreement, the congestion detected on the network, or by an administrator.

10. The system of claim 8 , wherein the specified communication rates are set automatically.

11. The system of claim 8 , wherein dropping communication messages comprises randomly dropping a communication message.

12. The system of claim 8 , wherein a communication message is randomly dropped when a drop probability for the virtual machines is greater than a nonce generated by a datacenter platform.

13. The system of claim 10 , wherein the specified communication rates are automatically decreased as congestion on the communication network increases.

14. The system of claim 8 , wherein the specified communication rates comprise a desired communication rate.

15. One or more hardware computer-readable media having embodied thereon computer-useable instructions that, when executed, perform steps comprising:
detecting congestion on a network servicing virtual machines running one or more datacenter applications, wherein the congestion is detected by way of a controller that monitors virtual machine communication traffic on the network;
confirming whether specified communication rates for the virtual machines in the datacenter platform are achieved; and
dropping communication messages for the virtual machines based on whether the specified communication rates are achieved, wherein dropping communication messages comprises randomly dropping a communication message.

16. The media of claim 15 , wherein the specified communication rates are set based on one or more of a service level agreement, the congestion detected on the network, or by an administrator.

17. The media of claim 15 , wherein the specified communication rates are set automatically.

18. The media of claim 15 , wherein the specified communication rates comprise a desired communication rate.

19. The media of claim 15 , wherein the communication message is randomly dropped when a drop probability for the virtual machines is greater than a nonce generated by a datacenter platform.

20. The media of claim 19 , wherein the nonce comprises a ratio of a random number generated by a nonce engine to a maximum random number generated by the nonce engine.
