[0039] In order to be able to describe the technical content of the present invention more clearly, further description will be given below in conjunction with specific embodiments.
[0040] The technical solution of the present invention re-divides the entire complex network to form multiple sub-networks / clusters. The division principle can be based on geographic location, virtualization technology used, and so on.
[0041] Deploy the SDN controller in a layered manner, deploy a centrally controlled SDN controller, and on-demand SDN controllers in each sub-network / cluster.
[0042] The central SDN controller periodically understands the resource occupancy of each sub-network / cluster through interaction with MANO (Management and Orchestration).
[0043] After the vSwitch in the sub-network / cluster receives the data packet to be forwarded, it judges whether the destination of the data packet is within the sub-network / cluster or needs to cross the sub-network / cluster according to the sto...
