Embodiment Construction

[0043] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0044] The main solution of the embodiment of the present invention is: use the inherent layer 2 firewall function in the terminal equipment to carry out directional modification to the transmission of the layer 2 message, for example, for the data flow message transmitted to different LAN side ports, some The ports on the LAN side discard data flow packets, and some ports on the LAN side pass data flow packets, thereby realizing the function of a virtual local area network. Thereby, the technical problem that the terminal equipments in the prior art are not compatible due to the absence of a unified standardized protocol among the terminal manufacturers of the Internet of Things is solved.

[0045] refer to figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the virtual local area network imp...

Abstract

The invention discloses a virtual local area network realization method and a terminal device. The method includes: copying the layer-2 data stream messages entered by each LAN side port to each LAN side port; according to at least one preset virtual local area network, and Layer-2 firewall rules are configured for the connectivity between the ports; according to the layer-2 firewall rules, the layer-2 data flow packets that need to be forwarded or discarded in each virtual local area network are respectively determined. The invention realizes the function of the virtual local area network and improves the compatibility of the terminal equipment without increasing the hardware cost of the terminal equipment.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a virtual local area network realization method and terminal equipment. Background technique [0002] With the vigorous development of the Internet of Things technology, it has gradually become a trend to divide different terminal devices in the Internet of Things into different virtual local area networks for unified planning and management. [0003] At present, the standard protocol 802.1Q is mainly used to realize the virtual local area network, that is, the method of adding a VLAN (Virtual Local Area Network, virtual local area network) message header to the common message of the two-layer protocol divides different virtual local area network data packets, Such as using port division, MAC address division, network layer division or IP multicast division. That is, use the VLAN protocol supported by all devices in the LAN to divide the configuration of the virtua...
