US 11,121,971 B2 · Method and apparatus for switching data between virtual machines, and communications system

Abstract

A method for switching data between virtual machines is provided, the method includes acquiring data that is inside a physical host and needs to be sent to a destination node; determining, according to the data, whether the destination node is a node inside the physical host or a node outside the physical host; and when the destination node is a node inside the physical host, determining a destination virtual network interface card (NIC) port, and sending the data to a corresponding destination virtual machine using a virtual NIC corresponding to the destination virtual NIC port; or when the destination node is a node outside the physical host, determining a physical NIC port, and sending the data outside the physical host using a physical NIC corresponding to the physical NIC port. A corresponding apparatus and system are also provided.

Dependent claims

A method for switching data between virtual machines, wherein the method comprises:

acquiring, by a switch in a physical host, data to be sent to a destination node external to the physical host;
acquiring, by the switch in the physical host, a sending virtual network interface card (NIC) port used to receive the data;
determining, by the switch in the physical host, a physical NIC port corresponding to the sending virtual NIC port by searching a port mapping table, wherein the port mapping table comprises a correspondence between virtual NIC ports and physical NIC ports;
delivering a media access control (MAC) address of a virtual NIC corresponding to the sending virtual NIC port into a unicast list of a physical NIC corresponding to the physical NIC port;
and
sending the data outside the physical host using the physical NIC corresponding to the physical NIC port.

3 more elements

A communications system comprising a first physical host and a second physical host, wherein the first physical host is configured to:

acquire, by a switch in the first physical host, data to be sent to the second physical host;
acquire a sending virtual network interface card (NIC) port used to receive the data;
determine, by the switch, a physical NIC port corresponding to the sending virtual NIC port by searching a port mapping table, wherein the port mapping table comprises a correspondence between virtual NIC ports and physical NIC ports;
deliver a media access control (MAC) address of a virtual NIC corresponding to the sending virtual NIC port into a unicast list of a physical NIC corresponding to the physical NIC port;
and
send the data to the second physical host using the physical NIC corresponding to the physical NIC port.

3 more elements

A physical host, comprising:

a memory configured to store instructions;
and
a processor coupled to the memory and configured to:
acquire data to be sent to a destination node which is external to the physical host;
acquire a sending virtual network interface card (NIC) port used to receive the data;
determine a physical NIC port corresponding to the sending virtual NIC port by searching a second port mapping table, wherein the port mapping table comprises a correspondence between virtual NIC ports and physical NIC ports;
deliver a media access control (MAC) address of a virtual NIC corresponding to the sending virtual NIC port into a unicast list of a physical NIC corresponding to the physical NIC port;
and
send the data outside the physical host using the physical NIC corresponding to the physical NIC port.
