SD-WAN SYSTEM, USE METHOD OF SD-WAN SYSTEM, AND RELATED APPARATUS

摘要

The present application relates to the technical field of communications, and discloses an SD-WAN system, a use method of an SD-WAN system, and a related apparatus. In the present application, the SD-WAN system comprises: a virtual logical network layer, a physical network layer, a network interconnection layer, and a user layer. The virtual logical network layer is physically connected to the physical network layer and is communicatively connected to the network interconnection layer. The network interconnection layer is physically connected to the physical network layer and is communicatively connected to the user layer. The network interconnection layer is used to receive data on access of the user layer to the physical network layer, to send an access request generated according to the access data to the virtual logical network layer, and to transfer the access data to the physical network layer under the control of the virtual logical network layer. The virtual logical network layer is used to control, according to the access request, the network interconnection layer to transfer the access data to the physical network layer. The SD-WAN system enables transformation of an existing WAN into an SD-WAN.
