Wherein action corresponding to the source flow table entry may include: for a traffic packet whose destination address matches the destination address, by using MAC address of a vSwitch connected with the source address as outer layer source MAC address and using MAC address of a vSwitch connected with the destination address as outer layer destination MAC address, encapsulating the traffic packet into a packet having double layer VLAN tags, and forwarding the packet from a port leading to a physical network card of the physical server where the vSwitch is deployed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Flow transmission","description":"A SDN controller receives a packet related to flow which is uploaded from a vSwitch, and if source address and destination address of the packet related to flow belong to different physical servers, t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10476981","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
