Abstract
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, the SDN controller may distribute a source flow table entry to the vSwitch which uploads the packet related to flow. 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.
