Abstract

A method and computing device for selecting a protocol stack for performing protocol processing on data is presented. The computing device is configured with a hypervisor for managing a first virtual machine. According to the method, when a socket creation instruction sent by the first virtual machine is received, a protocol stack instance is selected from the protocol stack instances provided by the computing device. Then, a socket is created in the selected protocol stack instance according to the socket creation instruction; and a creation result is transmitted to the first virtual machine. Therefore, in a virtualized environment, multiple virtual machines disposed in a same computing device can share a network protocol processing capability, and protocol stacks of the virtual machines achieve load balance.
