Lotus is resolved to port-mark, then finds that the physical port corresponding to port-mark carried in message is sent out by network boundary
SCN Space Cable Network border finds message.
In a kind of preferred implementation of the embodiment of the present invention, the heading of network boundary discovery message can also be taken
Band finds the information of message for instructing the OpenFlow network equipment to send network boundary by physical port；Based on this information,
The OpenFlow network equipment, can be directly from heading when receiving the network boundary discovery message from OpenFlow controller
In be resolved to this information, the physical port then indicated by this information send this network boundary find message.Such as, network edge
Boundary finds to carry in message for instructing the OpenFlow network equipment 1 to send the information of network boundary discovery message by port 1
Time, the OpenFlow network equipment 1, after receiving corresponding network boundary discovery message, determines and needs to send network by port 1
Border finds message, and sends network boundary discovery message by this port 1.
Under the application scenarios shown in Fig. 2, the OpenFlow network equipment 1 receiving from OpenFlow controller is
When the network boundary of port 1 structure of the OpenFlow network equipment 1 finds message, send this network boundary by port 1 and find
Message.The OpenFlow network equipment 1 is receiving the port 2 for the OpenFlow network equipment 1 from OpenFlow controller
