Embodiment Construction
[0039] In order 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 scheme of the present invention re-divides the entire complex network to form multiple sub-networks / clusters, and the division principle can be based on geographic location, virtualization technology used, and the like.
[0041] Deploy SDN controllers in a layered manner, deploy a centrally controlled SDN controller, and on-demand SDN controllers in each subnet / cluster.
[0042] The central SDN controller periodically learns about the resource occupancy of each sub-network / cluster by interacting with MANO (Management and Orchestration, management and orchestration).
[0043] After the vSwitch in the subnetwork / cluster receives the data packet to be forwarded, it judges whether the destination of the data packet is within the subnetwork / cluster or across subnetworks / clusters according to...
