Shaping virtual machine communication traffic

摘要

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.

主权项

1. One or more computer-readable media storing instructions to perform a method to drop virtual machine communication traffic, the method comprising:
calculating an exponentially weighted average for a sending rate of a virtual machine; identifying a desired sending rate for the virtual machine; evaluating a drop probability for a communication message sent from the virtual machine; and dropping a communication message when a nonce generated for the virtual machines is greater than the drop probability.
