- Appl. No: 16/830809
- Application Filed: March 26, 2020
- Claim: 1. A method, comprising: receiving, by a network controller, a virtual machine (VM) event, wherein the VM event comprises a VM identifier and an operating status of a VM corresponding to the VM identifier; determining, by the network controller, the VM as a target VM when the VM is a secondary VM; determining, by the network controller, a top of rack (TOR) switch corresponding to the target VM; generating, by the network controller, instruction information when an operating status of the target VM is a secondary operating state, wherein the instruction information comprises a VM identifier of the target VM, and the instruction information is used to instruct the TOR switch not to forward a broadcast, unknown unicast, or multicast (BUM) data packet to the target VM; and sending, by the network controller, the instruction information to the TOR switch.
- Claim: 2. The method according to claim 1, wherein the sending, by the network controller, the instruction information to the TOR switch comprises: sending, by the network controller, a forwarding traffic access control list to the TOR switch, wherein the forwarding traffic access control list corresponds to the target VM, and the forwarding traffic access control list comprises the instruction information.
- Claim: 3. The method according to claim 1, wherein the VM event further comprises one or more of: a name of the secondary VM, a physical host name of the secondary VM, a port group of the secondary VM, and a media access control (MAC) address of the secondary VM.
- Claim: 4. The method according to claim 1, wherein the operating status of the target VM is a fault tolerance (FT) state.
- Claim: 5. The method according to claim 1, wherein the operating status of the target VM is represented by using a number
- Claim: 6. The method according to claim 1, wherein the secondary operating state is represented by using a number 0, and a primary operating state is represented by using a number 1.
- Claim: 7. The method according to claim 1, wherein the operating status of the target VM is represented by using a true value or a non-value.
- Claim: 8. The method according to claim 1, wherein the network controller and the TOR switch are in a same network.
- Claim: 9. The method according to claim 8, wherein the network is software-defined networking (SDN).
- Claim: 10. The method according to claim 1, wherein the secondary VM is a backup VM of a primary VM.
- Claim: 11. The method according to claim 10, wherein the primary VM and the secondary VM are on different physical hosts.
- Claim: 12. A method, comprising: receiving, by a top of rack (TOR) switch, instruction information, wherein the instruction information comprises a VM identifier of a target virtual machine (VM), and the instruction information is used to instruct the TOR switch not to forward a broadcast, unknown unicast, or multicast (BUM) data packet to the target VM; and skipping, by the TOR switch, forwarding a received BUM data packet to the target VM according to the instruction information when the TOR switch receives the BUM data packet and the received BUM data packet needs to be sent to the secondary VM.
- Claim: 13. The method according to claim 12, wherein the receiving, by a TOR switch, instruction information comprises: receiving, by the TOR switch, a forwarding traffic access control list (ACL), wherein the ACL comprises the instruction information; the method further comprises: generating, by the TOR switch, an outgoing interface list (OIF) based on the ACL, wherein the OIF comprises the instruction information; and the skipping, by the TOR switch, forwarding a received BUM data packet to the target VM according to the instruction information when the TOR switch receives the BUM data packet and the received BUM data packet needs to be sent to the secondary VM comprises: skipping, by the TOR switch, forwarding the BUM data packet to the target VM when the TOR switch receives the BUM data packet and the TOR switch detects that a destination address of the BUM data packet comprises an address of the target VM in the OIF.
- Claim: 14. The method according to claim 12, wherein the instruction information is sent by a network controller to the TOR switch.
- Claim: 15. The method according to claim 14, wherein the network controller and the TOR switch are in a same network.
- Claim: 16. The method according to claim 15, wherein the network is software-defined networking (SDN).
- Claim: 17. A network controller, comprising a processor and a communications interface, wherein the communications interface is configured to receive a virtual machine (VM) event, wherein the VM event comprises a VM identifier and an operating status of a VM corresponding to the VM identifier; the processor is configured to: determine the VM as a target VM based on the VM event when determining that the VM is a secondary VM; determine a top of rack (TOR) switch corresponding to the target VM; and generate instruction information when detecting that the operating status of the secondary VM is a secondary operating state, wherein the instruction information comprises a VM identifier of the target VM, and the instruction information is used to instruct the TOR switch not to forward a broadcast, unknown unicast, or multicast BUM data packet to the target VM; and the communications interface is further configured to send the instruction information to the TOR switch.
- Claim: 18. The network controller according to claim 17, wherein the VM event further comprises one or more of: a name of the secondary VM, a physical host name of the secondary VM, a port group of the secondary VM, and a media access control (MAC) address of the secondary VM.
- Claim: 19. The network controller according to claim 17, wherein an operating status of the target VM is a fault tolerance (FT) state.
- Claim: 20. The network controller according to claim 17, wherein an operating status of the target VM is represented by using a number, or an operating status of the target VM is represented by using a true value or a non-value.
