Communication method and device, switch, AP and AC

Abstract

The invention provides a communication method and device, a switch, an AP and an AC, and is applied to the technical field of communication, the wireless AC is used as an authentication NAS point of awireless terminal, a wired switch is used as a micro-segmentation scheme for data forwarding, a VLAN identity identifier is used for representing a micro-segment, the VLAN identity identifier is converted into an SGT form on the wired switch, and on the basis of an Overlay network and the micro-segmentation scheme, wired and wireless integrated communication is achieved. According to the method and the system, communication based on the Overlay technology can be realized without supporting the Overlay protocol by the AP, the requirement on the AP is reduced, network access of various types ofAPs can be realized through the AC, and the method and the system are high in applicability and high in compatibility.

Description

technical field [0001] The present application relates to the technical field of communication, in particular to a communication method, device, switch, AP and AC. Background technique [0002] With the rapid development of wireless networks, wireless networks, as an extension of wired networks, have become a necessary means to improve the level of informatization. How to reasonably plan and integrate the wired network and wireless network to ensure the security of network information and the consistency of network security policies is an urgent problem to be solved. [0003] Overlay (overlay network) is to superimpose a virtual network on the existing physical network. Generally, the virtual network here refers to the virtual layer 2 network. This model can bring many benefits such as configuration simplification and terminal migration. Typical layer 2 Overlay technologies include: VXLAN (Virtual Extensible Local Area Network, virtual extended local area network), NVGRE (N...

Problems solved by technology

[0005] Taking VXLAN technology as an example, based on the above communication process, because the identity is acquired on the AC, in the prior art, the AC assigns the VXLAN identity to the terminal, and the VXLAN tunnel is used between the AP and the Leaf (aggregation switch), so the AP is required to support the VXLAN tunnel. Encapsulation requires high AP performance. For AP networks that cannot support VXLAN technology, VXLAN technology cannot be applied, so network communication based on VXLAN and other Overlay technologies cannot be realized.
