Problems solved by technology

[0007] The disadvantage of this scheme is: multiple ports need to be used when implementing VLAN switching, and multiple ports need to be connected to multiple physical lines, which will directly increase the transmission cost; multiple IP addresses must also be used when implementing VLAN switching, which increases the number of IP addresses. Consumption

Abstract

The embodiment of the invention provides a data transmission method, a device and a system of virtual local area networks. The method comprises the following steps: respectively establishing corresponding index for a plurality of virtual local area networks connected with the same port of the device; selecting one established index as the main index and establishing the binding relation between the device port and the main index; and sending the data packet of the device port to a router through the virtual local area network corresponding to the main index. In the embodiment of the invention, corresponding indexes are respectively established for the multiple VLANs which are connected with the same port of the device, and the actually used VLAN is selected by selecting a main index; in the method, device and system of the embodiment of the invention, the connection between the port and a plurality of virtual local area networks can be realized without increasing the number of device ports and the quantity of IP addresses, and data can be sent to the router through a plurality of virtual local area networks, thus reducing the requirements on ports and IP and having no influence on the up-level application.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a data transmission method, device and system of a virtual local area network. Background technique [0002] Ethernet (Ethernet) technology is easy to use, low in price, and has strong bandwidth scalability. Whether it is a service or a network structure, it has been widely used in enterprise networks, metropolitan area networks, and wide area networks. . However, the maintainability and operability of traditional Ethernet are relatively poor. As the scope of Ethernet promotion gradually expands, operators have increasingly strong requirements for Ethernet OAM (Operations, Administration and Maintenance) functions. . [0003] IEEE (Institute of Electrical and Electronics Engineers, Institute of Electrical and Electronics Engineers) has conducted corresponding research work on Ethernet OAM. The current Ethernet OAM can be realized by solutions of two protocols: a solutio...
