The method includes receiving, by a physical host through a virtual bridge in the physical host, a network packet sent by a source virtual machine in the physical host, where the network packet carries a source media access control (MAC) address and a target MAC address; obtaining, by the physical host according to the source MAC address and the target MAC address by querying correspondence between each virtual machine MAC address and a security domain, a security domain to which the source virtual machine corresponds and a security domain to which a target virtual machine corresponds; and controlling, by the physical host, the virtual bridge to discard the network packet, when the security domain to which the source virtual machine corresponds is different from a security domain corresponding to the virtual bridge."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method, apparatus, host, and network system for processing packet","description":"A method, an apparatus, a host, and a network system for processing a packet.
